Key takeaways:

  • A 2024 study in the British Medical Journal found that Depo-Provera users face a 555% higher risk of meningioma brain tumors, prompting lawsuits against Pfizer for insufficient warnings about these risks.
  • To file a Depo-Provera lawsuit, claimants must have used the contraceptive injection at least twice, have medical proof linking it to a meningioma or brain tumor, and adhere to state-specific filing deadlines.
  • Pfizer is accused of failing to include meningioma warnings on U.S. labels, unlike in Europe, and not adequately disclosing other risks such as bone density loss, blood clots, and depression associated with long-term use.

What is the Depo-Provera Lawsuit?

Question: What is the Depo-Provera lawsuit?

Answer: Depo-Provera lawsuit claims are being filed by women across the United States against Pfizer (the manufacturer of Depo-Provera), alleging the company failed to adequately warn consumers about potential risks and complications associated with long-term use of the contraceptive injection.

Contraceptive drug Depo-Provera (medroxyprogesterone acetate) has been widely used as a contraceptive injection since its FDA approval in 1992, with millions of women receiving the injection every three months for birth control.

Recent investigations have unveiled concerning links between Depo-Provera use and serious health complications.

On this page, we’ll provide an overview of the Depo-Provera lawsuit, eligibility criteria for filing a Depo-Provera lawsuit, meningioma brain tumors associated with Depo-Provera, and much more.

  • January 2025 Updates:

    January 29th, 2025: JPML Hearing on Depo-Provera Lawsuits Scheduled for January 30

    The U.S. Judicial Panel on Multidistrict Litigation (JPML) is set to convene on January 30, 2025, to evaluate whether federal lawsuits related to Depo-Provera should be consolidated into a single multidistrict litigation (MDL).

    The lawsuits, brought against Pfizer and additional manufacturers of the contraceptive injection, allege that the drug raises the likelihood of developing intracranial meningiomas—potentially dangerous brain tumors.

    If approved, the MDL would centralize both existing and future cases before one judge, facilitating coordinated pretrial proceedings, discovery, and early bellwether trials.

    Pfizer and the manufacturers of generic versions of Depo-Provera recognize the need for consolidation, though they remain divided on where the cases should be centralized.

    While the MDL would streamline pretrial matters, each lawsuit will continue to proceed as an individual claim.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be eligible to seek compensation through a Depo-Provera Lawsuit.

    January 29th, 2025: Class Action Lawsuit Seeks Medical Monitoring for Depo-Provera Users

    A new class action lawsuit was filed on January 17 in the U.S. District Court for the Western District of Pennsylvania, seeking medical monitoring for women who received Depo-Provera injections for at least one year.

    The plaintiff, Patricia Bonilla, argues that long-term users of the birth control shot face a heightened risk of developing meningiomas and should have access to ongoing medical surveillance, such as MRIs and CT scans.

    The lawsuit requests the establishment of a nationwide class or state-based subclasses to address these concerns.

    Since its introduction in 1992, Depo-Provera has been prescribed to over 70 million women in the U.S. Although Bonilla has not been diagnosed with a tumor, she asserts that her 11-year use of the drug necessitates lifelong health monitoring.

    This medical monitoring class action is distinct from the numerous personal injury claims filed by women who have already developed meningiomas, many of whom have undergone surgery and experienced severe health effects.

    The central legal question in these cases is whether Pfizer and other drug makers failed to disclose critical safety risks linked to Depo-Provera, potentially leaving thousands of women vulnerable to serious health consequences without proper warnings.

    January 17th, 2025:  Depo-Provera Lawsuits Over Brain Tumor Risks Move Toward Potential MDL Consolidation

    The number of lawsuits alleging a connection between Depo-Provera and the development of meningioma brain tumors is rapidly growing and may soon be consolidated into multidistrict litigation (MDL).

    The U.S. Judicial Panel on Multidistrict Litigation (JPML) has scheduled a key hearing for January 30, 2025, at the Wilkie D. Ferguson, Jr. U.S. Courthouse in Miami, Florida.

    This hearing will determine whether the cases should be centralized under an MDL, a decision that could significantly influence the course of this litigation.

    The choice of MDL venue is a crucial factor in this decision, with New York and California emerging as the primary contenders.

    The venue will directly impact the litigation due to the issue of Innovator’s liability, which governs plaintiffs’ rights.

    Innovator’s liability is a legal principle that holds original manufacturers accountable for injuries caused by their products, even if the injuries stem from generic versions.

    Plaintiffs are advocating for the MDL to be established in California, where innovator liability laws allow claims against Pfizer by individuals who used generic forms of Depo-Provera.

    Notably, 18 of the 22 original lawsuits included in the MDL motion were filed in California.

    On the other hand, Pfizer is pushing for the MDL to be located in New York, where innovator liability is not recognized.

    If the MDL is centralized in New York, individuals who have used generic drug versions may be excluded from pursuing legal action.

    MDL consolidation is an efficient way to manage complex pharmaceutical cases involving numerous plaintiffs with varying injuries.

    Unlike class actions, MDLs preserve the individual nature of each case while centralizing pre-trial proceedings under one federal judge.

    This structure is particularly suitable for Depo-Provera litigation, where injuries like meningiomas associated with high-dose progestin require personalized evaluations of damages and circumstances.

    Once the MDL is established, plaintiffs can file short-form complaints linked to a master complaint, simplifying the process for new claimants and their attorneys.

    The MDL will then proceed toward resolution, including individual settlements or a broader global settlement agreement.

    A global settlement could involve creating a compensation fund to address claims collectively, using a settlement matrix to determine payouts.

    This approach ensures fairness and efficiency by considering each plaintiff’s unique circumstances and injuries, offering victims a streamlined path to justice.

    January 2nd, 2025

    Legal actions involving Depo-Provera are gaining traction not only in the United States but also in Australia, where women have reported developing brain tumors after prolonged use of the contraceptive injection.

    In Australia, a class action lawsuit is being filed against Pfizer, the manufacturer of Depo-Provera, with more women coming forward to report side effects and claim they were not adequately warned about the risks.

    A study published in the British Medical Journal (BMJ) found that women who used Depo-Provera for more than one year had a significantly higher risk—five to six times—of developing meningiomas compared to non-users.

    This alarming finding has led to lawsuits in several countries, including Australia, where the drug has been a widely used contraceptive for decades.

    Law firms are currently seeking participants for a class action lawsuit, arguing that Pfizer failed to properly inform users of the potential for serious risks, including brain tumors.

    The Australian lawsuit encompasses women who received Depo-Provera prescriptions from 1992 to the present, a period during which over 3.5 million prescriptions were dispensed in the country.

    Many of these women allege they were prescribed the injection for more than a decade, far exceeding medical guidelines that recommend a two-year maximum.

    Legal professionals in both Australia and the United States are investigating whether Pfizer neglected to disclose these risks, leaving millions of women unaware of the potential consequences.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be eligible to seek compensation through a Depo-Provera Lawsuit.

  • December 2024 Updates:

    December 30th, 2024: Plaintiffs Seek MDL Consolidation for Depo-Provera Lawsuits, Pfizer Agrees but Disputes Venue

    The Depo-Provera Lawsuit is ongoing. 

    As Depo-Provera lawsuits against Pfizer continue to gain momentum in federal court, plaintiffs have filed a motion to consolidate all cases related to the injectable contraceptive before a single judge.

    While Pfizer has agreed to the consolidation proposal, it disagrees with the plaintiffs’ suggested venue.

    Currently, more than 22 Depo-Provera lawsuits are pending in various U.S. District Courts across the country, including six in the Northern District of California, the venue proposed by the plaintiffs for centralizing discovery and pretrial proceedings.

    The plaintiffs have petitioned to combine the lawsuits into multidistrict litigation (MDL) to streamline the legal process and avoid duplicating efforts in multiple courts.

    Pfizer has supported the MDL consolidation but recommends transferring the cases to the Southern District of New York, citing its proximity to Pfizer’s corporate headquarters as beneficial for accessing key witnesses and evidence.

    The Judicial Panel on Multidistrict Litigation (JPML) is scheduled to review the venue and consolidation request at a hearing on January 30, 2025.

    If approved, all current and future Depo-Provera claims will be overseen by a single judge for pretrial motions.

    Individual cases may still go to trial if settlements are not reached.

    Depo-Provera has been linked to a significantly increased risk of developing meningiomas, a type of brain tumor.

    Research suggests that women who used the drug face a five-fold greater risk compared to those who did not.

    Most lawsuits allege that Pfizer failed to adequately warn consumers about these risks, making the MDL proposal a critical step in ensuring consistency in how these claims are handled.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be eligible to seek compensation through a Depo-Provera Lawsuit.

    December 27th, 2024: University of Plymouth Leads Research on Meningiomas in NF2-Related Schwannomatosis

    Researchers at the University of Plymouth are spearheading a project to investigate meningiomas in NF2-related schwannomatosis (NF2-SWN), a condition caused by the loss of the NF2 gene.

    Although meningiomas are generally non-cancerous, they can significantly impact patients’ quality of life.

    Supported by the Children’s Tumor Foundation, the project focuses on developing a humanized model to study interactions between human immune cells and meningioma tumors.

    This research is essential for advancing new therapies, particularly as meningiomas have shown resistance to chemotherapy.

    While surgery is the primary treatment for most meningiomas, recurring or aggressive cases often require additional drug therapies, highlighting the need for improved treatment options.

    Recent findings have also suggested a possible connection between Depo Provera, a hormonal contraceptive, and an increased risk of meningiomas.

    Over 75 million women globally have reported using this drug.

    Dr. Liyam Laraba leads the research at the University’s Brain Tumor Research Center of Excellence.

    Her team is working to create the humanized model by implanting human immune cells into mice, providing a more realistic approach to evaluating treatments prior to clinical trials.

    This initiative is part of the Children’s Tumor Foundation’s NF Preclinical Hub Funding Program, aimed at expediting drug discovery and preclinical research for neurofibromatosis disorders.

    Building on successful frameworks such as the NF Preclinical and Therapeutics Consortium, the program strives to accelerate the development of therapies for patients.

    The project holds promise for delivering more effective treatments for meningiomas and improving outcomes for individuals with NF2-SWN.

    December 20th, 2024: New Depo-Provera Lawsuit Filed in Louisiana, Alleging Long-Term Use Led to Brain Tumor

    The Depo-Provera Lawsuit is ongoing.

    A new lawsuit has been filed in the Eastern District of Louisiana against several pharmaceutical companies regarding the birth control drug Depo-Provera.

    The plaintiff alleges that long-term use of Depo-Provera led to serious health conditions, including intracranial meningioma and paradoxical vocal cord dysfunction.

    She began quarterly injections of Depo-Provera in 1992, shortly after the FDA approved the drug, and continued for three to four years.

    In February 2020, she was diagnosed with intracranial meningioma, a condition linked to long-term use of Depo-Provera, as supported by numerous studies.

    The lawsuit claims the defendants failed to warn her or her healthcare providers about the potential risks associated with extended use of the drug.

    The plaintiff seeks compensatory damages for medical expenses, lost income, and other harm, as well as punitive damages for alleged negligence.

    Currently, over 22 federal Depo-Provera lawsuits are pending across the United States, with the majority filed in California.

    December 13th, 2024: Depo-Provera Users Pursue Legal Action Against Pfizer Over Brain Tumor Risks

    Women who have used Depo-Provera, an injectable contraceptive produced by Pfizer, are pursuing legal action after experiencing severe side effects, including brain tumors.

    Meningioma, a type of brain tumor that forms in the membranes surrounding the brain, can cause symptoms such as headaches, vision disturbances, and seizures.

    The lawsuits allege that Pfizer failed to provide adequate warnings about the potential dangers of long-term Depo-Provera use.

    Approved by the FDA in 1992 as a contraceptive, Depo-Provera contains medroxyprogesterone acetate, an ingredient used in other treatments since 1959.

    The drug was promoted as a convenient birth control option, requiring only four injections annually, catering to individuals seeking reliable and low-maintenance contraception.

    However, plaintiffs argue that this convenience came at the expense of unreported health risks.

    A French study published in March 2024 found that using Depo-Provera for one year or more increased the risk of developing meningioma by 5.55 times.

    The research analyzed data from over 18,000 women who underwent surgery for meningiomas between 2009 and 2018, supporting claims that prolonged Depo-Provera use significantly raises the risk of these tumors.

    One plaintiff, referred to as T.C. for privacy reasons, stated she used Depo-Provera for three years and was later diagnosed with a meningioma.

    During her use, she experienced prolonged bleeding, intense headaches, and severe fatigue.

    After her diagnosis, T.C. underwent regular MRIs and treatments to monitor the tumor’s growth, which she describes as an ongoing source of anxiety.

    Plaintiffs and their lawyers are advocating for increased awareness of the risks associated with Depo-Provera, urging women to consult medical professionals if they notice adverse symptoms and to consider legal action if a brain tumor develops.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be eligible to seek compensation through a Depo-Provera Lawsuit.

    December 11th, 2024: California Woman Files Suit Over Depo-Provera-Related Brain Tumor

    Another California resident has initiated legal proceedings in the U.S. District Court for the Eastern District of California, claiming that her use of Depo-Provera for approximately eight (8) years led to the development of an intracranial meningioma.

    The lawsuit targets Pfizer, Inc., Pharmacia & Upjohn Co. LLC, and Pharmacia LLC — alleging strict liability, negligence, and breach of warranty.

    The plaintiff contends that the defendants failed to provide adequate warnings about the risks associated with long-term use of Depo-Provera, particularly the potential for meningioma development.

    Having used the contraceptive from 1994 to 2002, she was diagnosed with a meningioma in 2015 after experiencing severe neurological symptoms.

    This case adds to the growing number of long-term usage claims and further solidifies California’s position as a focal point for Depo-Provera litigation, strengthening the argument for MDL consolidation in the state.

    December 7th, 2024: Philadelphia Resident Files Depo-Provera Lawsuit in State Court

    A new lawsuit has been filed in the Court of Common Pleas for Philadelphia County by a local resident, alleging that extended use of Depo-Provera resulted in the development of a debilitating meningioma.

    The plaintiff, who began using the injectable contraceptive as a teenager, claims that the manufacturers (including Pfizer and affiliated companies) failed to adequately warn users about the risks associated with medroxyprogesterone acetate — the active ingredient in Depo-Provera.

    The plaintiff, who has undergone multiple brain surgeries and continues to suffer from physical and cognitive impairments, is seeking both compensatory and punitive damages.

    The lawsuit also names healthcare providers affiliated with the University of Pennsylvania Health System as defendants — alleging their failure to disclose safer contraceptive alternatives.

    This case underscores the anticipated strong Depo-Provera docket in Philadelphia.

    December 6th, 2024: Inoperable Brain Tumors Emerge as Significant Concern in Depo-Provera Cases

    Legal representatives are observing a higher-than-expected incidence of inoperable meningiomas in Depo-Provera cases.

    These tumors, which cannot be safely removed due to their location or involvement with critical brain structures, pose significant challenges for patients and medical professionals alike.

    The impact of these inoperable tumors is profound, often resulting in persistent symptoms and ongoing health risks.

    Patients frequently report severe headaches, vision loss, memory problems, and other neurological impairments.

    Treatment options for these cases are limited, often restricted to radiation therapy or long-term monitoring, leaving patients to cope with both the physical and emotional toll of their condition.

    December 5th, 2024: Depo Provera Cases Expected to Proceed as MDL, Not Class Action

    Legal experts anticipate that lawsuits against Depo Provera manufacturers will likely be consolidated into a multidistrict litigation (MDL) rather than a traditional class action.

    This approach, common in complex pharmaceutical cases, allows for efficient handling of numerous claims while preserving individual case integrity.

    In an MDL, each plaintiff retains their own lawsuit, unlike a class action where one representative speaks for all.

    Cases are transferred to a single federal court, where a judge oversees pre-trial proceedings, addressing common issues such as the alleged link between Depo Provera’s high-dose progestin and meningiomas, and the adequacy of warning labels.

    The MDL structure offers benefits including individualized case consideration, streamlined pre-trial processes, and the option for either individual settlements or a global settlement agreement.

    This approach is particularly suited to the Depo Provera situation, where injuries and circumstances vary significantly among plaintiffs.

    December 4th, 2024: Proposed Depo-Provera Brain Tumor MDL Would Be Based in the United States District Court for the Northern District of California

    Attorneys representing plaintiffs in Depo-Provera lawsuits have filed a motion to centralize all related cases into a federal multidistrict litigation (MDL).

    The plaintiffs claim that Depo-Provera, a hormonal contraceptive containing medroxyprogesterone acetate, significantly increases the risk of developing brain tumors, with recent studies indicating a fivefold increase in risk for women using the product.

    These lawsuits accuse the drug’s manufacturers of failing to adequately warn both users and the medical community about these potential dangers.

    Many affected women have undergone invasive surgeries to treat their brain tumors and now face long-term consequences, including vision loss, seizure disorders, and lasting neurological damage.

    On November 26, a motion was submitted to the U.S. Judicial Panel on Multidistrict Litigation (JPML), seeking to consolidate at least 22 lawsuits currently pending in eight district courts nationwide.

    The proposed MDL would be based in the Northern District of California, where six of the cases are already filed.

    Plaintiffs argue that centralization is necessary because the lawsuits share nearly identical allegations and legal questions, which would help streamline pretrial proceedings, prevent inconsistent rulings, and reduce legal expenses.

    They also note that the litigation is expected to grow significantly, with additional claims anticipated in the coming months.

    If the JPML grants the motion, all current and future Depo-Provera lawsuits will be assigned to a single judge for coordinated pretrial proceedings, including discovery and motions.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be eligible to seek compensation through a Depo-Provera Lawsuit.

    December 2nd, 2024: 6 Manufacturers Named as Defendants in Proposed Depo-Provera Brain Tumor MDL

    Legal representatives for twenty-two (22) women have initiated federal proceedings against six (6) manufacturers of Depo-Provera and its generic counterparts.

    The motion for multidistrict litigation (MDL) consolidation identifies Pfizer, Pharmacia & Upjohn Co. LLC, Greenstone LLC, Viatris Inc., Pharmacia LLC, and Prasco LLC as defendants.

    Should the consolidation occur, these entities could face liability for producing and marketing a contraceptive associated with brain tumor development in numerous women.

  • November 2024 Updates:

    November 27th, 2024: Judicial Panel to Consider Consolidation of Depo-Provera Lawsuits into Multidistrict Litigation (MDL)

    Plaintiffs in the Depo-Provera lawsuits have filed a motion with the Judicial Panel on Multidistrict Litigation (JPML) to consolidate the cases into a single multidistrict litigation (MDL).

    With 22 cases currently pending, they have suggested the U.S. District Court for the Northern District of California as the venue, citing its track record with major MDLs, including Roundup.

    The next hearing on the motion is set for December 5th, 2024 — meaning the JPML will not review this litigation until 2025.

    If granted, it could become the first significant mass tort of the new year.

    Plaintiffs argue that centralized pretrial proceedings through an MDL are critical to addressing the complexities of Depo-Provera lawsuits, which allege serious health issues (including meningiomas) that are linked to prolonged use of the contraceptive.

    However, defendants are expected to oppose the motion and may propose transferring the cases to a District Court in New York.

    Karen Caldwell, the panel chair, will preside over the hearing scheduled for early 2025, with multiple filings expected in the interim.

    November 26th, 2024: Legal Grounds in the Depo-Provera Brain Tumor Lawsuit

    The Depo-Provera litigation centers on allegations that Pfizer neglected to adequately disclose critical side effects on product labels and possessed knowledge of the contraceptive’s link to brain tumors.

    Individuals diagnosed with brain tumors or meningiomas post-Depo-Provera use may be eligible for legal recourse.

    November 22nd, 2024: New Depo-Provera Lawsuits Name Healthcare Entities and Pharmacies

    A recent lawsuit filed on November 15th, 2024, in the Superior Court of California in Alameda County, has named not only the manufacturers of Depo-Provera but also healthcare entities and pharmacies as defendants.

    The plaintiff, Madison Le, alleges that these entities (including Kaiser Permanente International, Kaiser Foundation Health Plan Inc., and the Permanente Medical Group Inc.) were aware of the dangers associated with Depo-Provera through their own research but continued to administer and profit from the drug.

    This lawsuit underscores the expanding scope of liability in Depo-Provera cases — highlighting the role of healthcare providers and pharmacies in the administration of the drug.

    November 21st, 2024: Inoperable Brain Tumors Linked to Depo-Provera Use

    Recent findings have highlighted that some brain tumors associated with Depo-Provera use are inoperable due to their location or infiltration into critical brain structures.

    This means that affected women may require alternative treatments such as radiation therapy, hormone therapy, or participation in clinical trials — which can prolong their suffering and significantly impact their quality of life.

    The inoperability of these tumors underscores the severe consequences of Depo-Provera use and the need for comprehensive preoperative imaging to assess treatment options.

    November 20th, 2024: Las Vegas Woman Diagnosed with Multiple Brain Tumors After Long-Term Depo-Provera Use

    A woman in Nevada has filed a lawsuit against Pfizer, alleging that her 20-year use of Depo-Provera led to the development of three intracranial meningiomas.

    Tina Stephens-Smith experienced symptoms such as headaches, blurred vision, and speech problems before discovering the densely calcified tumors.

    Her case highlights the long-term risks associated with Depo-Provera and the failure of Pfizer to adequately warn U.S. women about these dangers.

    November 19th, 2024: Importance of Preoperative Imaging for Meningioma Patients

    A review article in the Journal of Neuroimaging emphasizes the critical role of preoperative imaging in managing intracranial meningiomas linked to Depo-Provera use.

    The article underscores the need for a strong foundation in the latest meningioma imaging techniques to optimize preoperative planning and improve patient outcomes.

    This highlights the importance of targeted imaging for women who have used Depo-Provera and developed brain tumors that can be treated surgically.

    November 15th, 2024: Study Finds 53% Increased Risk of Meningiomas After Depo-Provera Use

    Lawsuits claim that Depo-Provera (a contraceptive medication manufactured by the defendants) caused significant harm, with scientific research linking the active ingredient in Depo-Provera, medroxyprogesterone acetate (MPA), to meningiomas.

    A recent database analysis found that the injectable form of MPA raised the risk of developing meningiomas by 53%, with the risk increasing the longer the drug was used.

    Additionally, data from 2004 to 2015 show a notable rise in meningioma cases, particularly among females, African Americans, and younger individuals.

    Plaintiffs argue that the defendants were aware of this danger for decades but failed to warn U.S. patients and healthcare providers.

    In contrast to the U.S., warnings about meningiomas have been added to the labels for Depo-Provera in Europe and Canada.

    Depo-Provera’s known risks include:

    • Bone Mineral Density Loss: Long-term use (over two years) may lead to permanent bone loss, especially in adolescents and high-risk individuals.
    • Thrombosis: Discontinuation of the drug is recommended if thrombosis occurs, with further assessment required for any vision or neurological issues.
    • Cancer Risks: Some users may experience an increased risk of breast and cervical cancers, particularly those with a family history of breast cancer.
    • Ectopic Pregnancy: Severe abdominal pain or suspected pregnancy should prompt evaluation for an ectopic pregnancy.
    • Adverse Reactions: Includes anaphylaxis, weight gain, depression, and irregular bleeding.

    November 14th, 2024: Progesterone Study Strengthens Causation Claims in Depo-Provera Lawsuits

    A study by David Bailey from January 2024 provides critical evidence for Depo-Provera lawsuits.

    The study shows that stopping progesterone drugs like Depo-Provera can lead to the regression of meningioma size.

    This finding supports both general and specific causation claims, bolstering the argument that Depo-Provera can cause an increased risk of meningioma and that it caused the meningioma in specific plaintiffs.

    November 13th, 2024: Concerns Over Meningioma Risk Linked to Depo-Provera Continue to Grow

    Concerns about the potential risk of developing brain tumors (particularly meningiomas) after using Depo-Provera continue to escalate.

    Meningiomas are slow-growing tumors that can cause severe health issues due to increased pressure on brain tissue, nerves, and blood vessels.

    As more evidence emerges about the link between Depo-Provera and brain tumors, legal actions against Pfizer for failing to appropriately update the contraceptive’s warning label are intensifying.

    November 12th, 2024: Pfizer Includes Meningioma Warning for Canadian Patients But Not for U.S. Women

    Pfizer has included a warning about the association between Depo-Provera and meningiomas in its product monograph for Canadian patients since at least 2016.

    However, no such warning is included in the prescribing information for U.S. women.

    This discrepancy has led to numerous lawsuits against Pfizer, alleging that the company failed to adequately warn U.S. women about the dangers of Depo-Provera.

    November 9th, 2024: New Depo-Provera Lawsuit Filed in California Alleging Link to Meningioma

    Mayra Valencia has filed a lawsuit in the Eastern District of California, alleging that her 23-year use of Depo-Provera led to the development of a brain tumor.

    The complaint states that Pfizer knew or should have known about the risk of meningioma associated with Depo-Provera and failed to warn U.S. women.

    The lawsuit also highlights studies dating back to 1983 that show a correlation between progesterone use and meningioma.

    November 7th, 2024: Depo-Provera Settlement Amounts Could Be High Due to Several Factors

    Depo-Provera settlement amounts are projected to be substantial due to several factors.

    First, studies have shown a significant increase in the risk of brain tumors — with a 5.5x increased risk being one of the highest observed in mass torts.

    Second, the type of injury (brain tumors) is particularly severe.

    Additionally, Pfizer is well-funded and can afford significant settlements.

    Given the relatively low number of potential lawsuits (estimated to be between 5,000 to 30,000), settlement values could be higher than in other mass torts — potentially exceeding $100,000 per case.

    November 2nd, 2024: Depo-Provera Lawsuits Focus on Meningiomas and Potential Breast Cancer Link

    Depo-Provera has been scrutinized for its potential health risks, including an increased risk of meningiomas and possibly breast cancer.

    A 1988 study highlighted criticisms about the drug’s safety, including animal studies suggesting an increased cancer risk.

    While current lawsuits primarily focus on meningiomas, there may also be a link to an increased risk of breast cancer for long-term users of Depo-Provera.

    November 1st, 2024: Another Woman Files Depo-Provera Lawsuit Against Pfizer

    A California woman, Anjanna Lawson, has filed a lawsuit against Pfizer and other defendants after being diagnosed with an intracranial meningioma.

    Lawson started receiving Depo-Provera injections at age 16 and continued until September 2024.

    Despite undergoing a right pterional craniotomy in July 2023 to remove the tumor, a residual tumor was discovered in early 2024, necessitating five sessions of stereotactic radiosurgery.

    The tumor remains uneradicated, causing Lawson to suffer from vision loss, facial spasms, and a burning sensation in her face.

    Her lawsuit seeks damages from Pfizer, Inc., Viatris, Inc., Greenstone, LLC, Prasco, LLC, Pharmacia & Upjohn LLC, and Pharmacia, LLC — alleging that these entities failed to adequately warn about the risks associated with Depo-Provera use.

    Key notes regarding Anjanna Lawson’s Depo-Provera lawsuit:

    • Plaintiff: Anjanna Lawson (a California resident).
    • Defendants: Pfizer, Inc., Viatris, Inc., Greenstone, LLC, Prasco, LLC, Pharmacia & Upjohn LLC, and Pharmacia, LLC.
    • Allegations: Failure to warn about the risks of developing intracranial meningiomas associated with Depo-Provera use.
    • Symptoms: Vision loss, facial spasms, and a burning sensation in the face due to an uneradicated tumor.
    • Treatment: Right pterional craniotomy and stereotactic radiosurgery.
    • Lawsuit Focus: Seeking damages for the harm caused by Depo-Provera use.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be entitled to seek compensation through a Depo-Provera Lawsuit.

  • October 2024 Updates:

    October 30th, 2024: JPML Hearing Set for December 5th, 2024

    The Depo-Provera lawsuit is ongoing. 

    Depo-Provera Lawsuits continue to be actively filed in federal courts, with projections suggesting over 30 cases could be filed by the end of November.

    These filings are primarily concentrated in the Northern District of California and the Southern District of Texas.

    A significant Judicial Panel on Multidistrict Litigation (JPML) hearing (to consider the potential for case consolidation into an MDL) is set for December 5th, 2024. 

    However, the formation of an official multidistrict litigation (MDL) is not expected before year-end.

    An MDL typically forms when 25 or more related cases, addressing similar legal issues and involving the same defendants, are pending in various federal courts.

    This threshold is anticipated to be met with the Depo-Provera cases.

    While plaintiffs may prefer California as the coordination venue, defendants are expected to oppose this and suggest New York instead.

    October 29th, 2024: New Depo-Provera Lawsuit Filed in California with Potential for Multidistrict Consolidation

    The Depo-Provera lawsuit is ongoing. 

    A new case has been filed in the U.S. District Court for the Central District of California, accusing the makers of Depo-Provera of contributing to the development of a meningioma brain tumor in a woman who used the birth control shot for nearly 25 years.

    The plaintiff is bringing legal action against Pfizer, Viatris, Greenstone, Prasco, and Pharmacia & Upjohn — claiming the companies did not provide adequate warnings in the U.S. regarding the risk of brain tumors (a warning that has been included on Canadian labels since 2015).

    According to the lawsuit, the plaintiff began using Depo-Provera injections in 2000 and received a total of 91 doses over her treatment period.

    In 2020, she started experiencing severe symptoms (including headaches, blurred vision, vertigo, and ear itching) — leading to the diagnosis of a calcified meningioma brain tumor that continued to grow.

    Due to its calcified nature, surgical removal has been deemed too dangerous, leaving her with chronic pain and ongoing symptoms.

    The complaint further alleges that Pfizer and related companies failed to adequately research and disclose the potential risks of long-term Depo-Provera use, which could include the development of meningiomas.

    This case adds to the increasing number of Depo-Provera lawsuits being filed nationwide.

    October 25th, 2024: Second Depo-Provera Lawsuit Filed Against Pfizer by Indiana Woman

    An Indiana woman, Lesley Noble, has filed a lawsuit against Pfizer, alleging that her 20-year use of Depo-Provera caused her brain tumor and subsequent injuries.

    Noble underwent invasive surgery to remove her intracranial meningioma in 2017, but the tumor aggressively regrew after six months.

    She then underwent 36 rounds of radiation while still taking Depo-Provera, unaware of its potential causation.

    Noble and her husband, Justin Noble, are demanding a jury trial for her injuries.

    October 22nd, 2024: Pfizer and Co-Defendants Face 9 Accusations In First Depo-Provera Lawsuit

    Pfizer and its co-defendants, including Viatris, Inc., Greenstone LLC, Prasco Labs, and Pharmacia & Upjohn, face nine allegations of wrongdoing in a federal Depo-Provera lawsuit filed by Kristina Schmidt in California.

    The charges include Failure to Warn, Design Defect, Negligence, Negligent Failure to Warn, Negligent Design Defect, Negligent Misrepresentation, Fraudulent Misrepresentation, Breach of Express Warranty, and Breach of Implied Warranty.

    These allegations accuse Pfizer and the other defendants of knowingly designing, marketing, and manufacturing a drug that could cause intracranial meningiomas without proper warning.

    October 17th, 2024: Evidence Suggests Exposure to Hormones in Depo-Provera May Cause Spinal Tumors

    Recent studies have linked Depo-Provera use to brain tumors, specifically intracranial meningiomas.

    New research is focusing on meningiomas that form on the spinal cord.

    An article in Neuro-Oncology Advances notes that while less than 13% of meningiomas are on the spinal cord, they make up about a quarter of spinal cord tumors.

    The article suggests that external hormone sources, such as Depo-Provera injections, may be linked to a higher risk of developing meningiomas in the brain or spinal cord.

    October 11th, 2024: Pfizer’s Legal Battle Over Depo-Provera and Generic Drug Liability

    A central issue in the Depo-Provera lawsuit is whether Pfizer is legally responsible for meningiomas caused by generic versions of Depo-Provera.

    The Supreme Court’s ruling in Mutual Pharmaceutical Co. v. Bartlett states that generic drug manufacturers are not liable if their drug has the same active ingredient as an approved drug.

    However, in the Depo-Provera case, the generic manufacturers are mostly wholly owned subsidiaries of Pfizer, and the drugs were manufactured at the same sites as Depo-Provera.

    This issue is expected to be aggressively litigated as part of the lawsuit.

    October 10th, 2024: Statute of Limitations Considerations in Depo-Provera Lawsuits

    The Depo-Provera lawsuits have highlighted important legal issues regarding the statute of limitations in such cases.

    There are two (2) key factors that may allow individuals to file lawsuits for Depo-Provera-related injuries without being hindered by the statute of limitations:

    1. The “Discovery Rule”
    2. The Doctrine of Fraudulent Concealment

    The first is the “Discovery Rule” — which is recognized in many states and allows the statute of limitations to be extended.

    This rule delays the filing deadline until the injured party becomes aware of both the injury and its cause.

    In the case of Depo-Provera, recent studies have uncovered a possible link between the drug and brain tumors, a connection that was not widely known before.

    Because this evidence has only recently emerged, plaintiffs were not expected to know about the potential link between their conditions and Depo-Provera until now.

    The second factor is the Doctrine of Fraudulent Concealment, which could also apply.

    This legal doctrine allows the statute of limitations to be paused if the defendant deliberately hides key safety information.

    Plaintiffs claim that Depo-Provera’s manufacturers concealed the drug’s risks by altering safety warnings and product labeling — making it difficult for consumers to identify the potential connection between Depo-Provera and brain tumors like meningiomas.

    This alleged concealment means plaintiffs may argue they were unable to learn of the risks in time — effectively extending their window to file a lawsuit.

    Together, the discovery rule and fraudulent concealment may provide a strong foundation for plaintiffs to challenge statute of limitations issues in the Depo-Provera lawsuits.

    October 4th, 2024: Woman Files Lawsuit Against Pfizer Alleging Depo-Provera Caused Her Brain Tumor

    Kristina Schmidt has filed a lawsuit against Pfizer in the Northern District of California, alleging that Depo-Provera caused her intracranial meningioma.

    Her attorneys claim that Pfizer knew or should have known for decades that Depo-Provera could cause or substantially contribute to the development of meningiomas.

    Since her diagnosis, Schmidt has endured significant, invasive treatments and experienced serious injuries.

    This case is part of a growing number of lawsuits against Pfizer for their injectable contraceptive.

    October 3rd, 2024: Depo-Provera Tied to Highest Cancer Rate Increase Among Commercial Drugs

    Lawyers are highly interested in pursuing Depo-Provera lawsuits because early studies indicate that the drug makes the diagnosed injury over five times more likely to occur, one of the highest increases in cancer rates among commercially available drugs.

    This contrasts with the Roundup lawsuit, where lawyers argued that Roundup causes a 69% increase in the likelihood of cancer — leading to several verdicts over $1 billion.

    The proof in the Depo-Provera case is believed to be even stronger.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be entitled to seek compensation through a Depo-Provera Lawsuit.

  • September 2024 Updates:

    September 30th, 2024: Depo-Provera Lawsuit Expands as More Plaintiffs Learn of Potential Risks

    The Depo-Provera lawsuit is gaining momentum as more potential plaintiffs become aware of the allegations against Pfizer.

    A French study has established a link between Depo-Provera injections and meningiomas (tumors that arise from the protective membranes covering the brain and spinal cord).

    Symptoms of meningioma may include (but are not limited to):

    • Headaches
    • Vision changes
    • Seizures
    • Memory loss
    • Dizziness

    Further research is needed to understand why Depo-Provera may increase the risk of tumor growth.

    With 74 million women worldwide having used the drug, the potential scale of this litigation is significant.

    September 25th, 2024: Depo-Provera’s Tumultuous History and Rising Legal Challenges

    Depo-Provera’s journey has been marked by regulatory ups and downs since its development in 1959.

    Initially approved by the FDA in 1974, the drug’s approval was revoked in 1978 due to cancer-related concerns.

    It regained FDA approval in 1992 as a contraceptive.

    Recent research (including a study published in the British Medical Journal) has uncovered a potential link between Depo-Provera use and the development of meningiomas and other brain tumors.

    Given its widespread use over five decades, experts anticipate a significant increase in lawsuits in the coming years.

    September 17th, 2024: Pfizer Confronts New Wave of Legal Action Over Depo-Provera

    Pfizer is facing renewed legal scrutiny regarding Depo-Provera.

    A recent study revealed that women who received as few as two Depo-Provera injections have a more than fivefold increased risk of developing meningiomas.

    This isn’t the first time the drug has been at the center of legal disputes.

    Previous lawsuits (such as the 2008 case Cassandra Colville v. Pharmacia & Upjohn) focused on allegations of bone density loss associated with the drug’s use.

    Since then, Pfizer has acquired the rights to manufacture and distribute Depo-Provera.

    September 13th, 2024: Study Reveals High-Value Potential of Meningioma Lawsuits Linked to Depo-Provera

    A 2020 analysis of 47 meningioma lawsuits has caught the attention of legal professionals investigating cases involving women who used Depo-Provera.

    The study found that in 68.1% of cases, failure to diagnose was the primary basis for legal action.

    Notably, the average verdict in these lawsuits amounted to $3,409,650.22 — with settlements averaging $867,555.56.

    These figures suggest that meningioma cases could result in substantial compensation.

    If a causal link between Depo-Provera and increased meningioma risk is established, legal experts project settlement values could reach several hundred thousand dollars — considering Pfizer’s financial capacity.

    September 10th, 2024: Potential Federal Consolidation of Depo-Provera Brain Tumor Claims

    Approximately one-quarter of sexually active women have used Depo-Provera at some point in their lives.

    As a result of its widespread use, numerous women diagnosed with brain tumors are now pursuing legal action against the drug’s manufacturers.

    Legal experts anticipate that these cases will likely be consolidated in federal court — paving the way for coordinated legal proceedings against the pharmaceutical companies involved.

    September 5th, 2024: Depo-Provera’s Complex Regulatory Past and Emerging Health Concerns

    Depo-Provera faced multiple FDA rejections throughout the 1970s and 1980s before finally gaining approval in 1992.

    Since its approval, the drug has been associated with reduced bone density and significant side effects upon discontinuation.

    Originally developed by Upjohn, Depo-Provera is now manufactured by Pfizer.

    Recent studies have further complicated the drug’s history by suggesting a potential link to brain tumors — adding to the existing health concerns surrounding its use.

    If you or a loved one developed a brain tumor after using Depo-Provera, you may be entitled to seek compensation through a Depo-Provera Lawsuit.

The Risks of Depo-Provera Usage

A 2024 study published in the British Medical Journal highlighted a significant link between the use of Depo-Provera and increased risks of developing brain tumors, particularly intracranial meningiomas.

Historically, concerns about other health risks such as osteoporosis and the serious dangers associated with prolonged Depo-Provera use were also known, indicating possible gaps in disclosure by Pfizer.

Scientific Studies Linking Depo-Provera to Brain Tumors

Recent scientific studies have shown a troubling link between the use of Depo-Provera and the development of specific types of brain tumors, such as meningiomas.

A study published in the British Medical Journal in March 2024 reported a 555% increased risk for meningiomas among Depo-Provera users compared to non-users.

This type of tumor grows within the meninges—the layers protecting the brain and spinal cord—which, despite being typically benign, can cause significant health issues due to their location.

These findings have intensified the scrutiny of Depo-Provera and its potential side effects, especially for users who have developed a brain tumor, making it a subject of concern for healthcare providers and patients alike.

Possible scientific implications and risks identified in studies include:

  • Significant increase in risk of intracranial meningiomas
  • Development of tumors within the meninges
  • Potential for pressure on brain structures causing symptoms

The linkage between Depo-Provera and meningiomas has been underscored by significant statistical data, which resonates deeply within the medical community.

While these tumors are usually benign, their presence can lead to complications depending on their size and location, affecting vital neurological functions.

Consequently, these findings have prompted further research into long-term safety and risk management for patients opting for hormonal contraceptive solutions like Depo-Provera.

Historical Warnings and Pfizer’s Knowledge of Risks

Pfizer, the manufacturer of Depo-Provera, has faced criticism for its handling of known risks associated with the contraceptive injection.

Historically, Depo-Provera has been flagged for its potential impact on bone health, specifically increasing the risk of osteoporosis.

The drug’s labeling includes warnings about the potential reduction in bone density, especially in women with additional risk factors such as metabolic bone disease or a family history of osteoporosis.

This has raised questions about whether Pfizer adequately communicated all the risks associated with long-term use of its product.

PTS: Pfizer’s historical risk disclosures include:

  • Osteoporosis risk due to bone density reduction
  • Impact on bone health during critical periods of bone accretion
  • Additional risks for patients with pre-existing risk factors like metabolic bone disease

The acknowledgment of such risks by Pfizer only partially addresses concerns, as some patients and health advocates argue more should have been done to ensure comprehensive awareness.

The historical warnings mainly emphasized bone health, seemingly overlooking or under-representing other potential severe side effects like brain tumors. Notably, Depo-Provera’s label in the U.S. lacks a meningioma warning, which is present on European labels. This discrepancy has sparked legal actions seeking accountability from Pfizer for what some claim is a failure to fully disclose the spectrum of risks associated with Depo-Provera, amplifying scrutiny over pharmaceutical practices and patient safety notifications.

Meningioma Brain Tumors Associated with Depo-Provera

Depo-Provera, a commonly used injectable contraceptive, has been linked to an increased risk of developing meningioma brain tumors.

Women who have been diagnosed with meningiomas after using Depo-Provera are being encouraged to file lawsuits against Pfizer, the manufacturer. These Depo-Provera meningioma lawsuits focus on the health risks of brain and spinal cord tumors linked to the contraceptive’s use and discuss the consolidation of lawsuits into multidistrict litigation (MDL).

This has given rise to a new wave of product liability claims, particularly as awareness spreads of the potential long-term health risks associated with this contraceptive.

The connection between meningiomas and Depo-Provera is now drawing significant legal attention in the area of product liability and pharmaceutical litigation.

Product Liability Claims Against Pfizer

Recent lawsuits have been filed against Pfizer, the manufacturer of Depo-Provera, primarily alleging that the company failed to adequately warn users about the risks of developing meningioma brain tumors.

Several cases highlight that long-term use of Depo-Provera has been linked to these tumors, which can lead to serious health complications. These Depo-Provera claims emphasize issues of negligence, design defects, and failure to provide adequate warnings about the risks, particularly focusing on the experiences of women who have suffered significant health issues after prolonged use of the contraceptive.

These lawsuits are significant as they focus on alleged negligence by Pfizer in informing the public and healthcare professionals about the potential risks involved with prolonged use of Depo-Provera.

Claims against Pfizer may include, but are not limited to:

  • Failure to warn patients of risks
  • Negligence in drug safety studies
  • Misrepresentation of product safety
  • Lack of adequate label warnings

These claims are rooted in the belief that Pfizer possessed or should have possessed sufficient knowledge about the risks associated with long-term Depo-Provera use, yet failed to inform users properly.

Lawsuits have been gaining momentum, with more individuals reporting adverse effects after years of using the contraceptive.

Judges and juries are now tasked with determining whether Pfizer’s actions or inactions constituted a breach of their duty to consumers, which has larger implications for pharmaceutical accountability.

Eligibility Criteria for Filing a Depo-Provera Lawsuit

To qualify for filing a lawsuit against Pfizer regarding Depo-Provera, individuals must typically meet certain eligibility criteria.

Claimants are often required to demonstrate that they have used Depo-Provera or its generic counterpart at least twice.

Furthermore, they must show medical documentation linking their use of the contraceptive to the subsequent development of a meningioma or similar brain tumor.

Meeting these criteria is crucial for establishing a legitimate legal claim against the pharmaceutical giant.

Eligibility criteria for filing include:

  • Use of Depo-Provera or equivalent at least twice
  • Development of meningioma or equivalent brain tumor
  • Medical records substantiating the link between drug use and health issues
  • Filing within the timeframe allowed by state laws

Prospective plaintiffs should gather comprehensive medical and pharmaceutical records to support their claims.

This documentation serves as the foundation for proving that Depo-Provera was a direct factor in their health issues.

Meeting these criteria and assembling the required documentation helps strengthen the case against Pfizer.

Additionally, consulting with an attorney specializing in product liability can provide further guidance on the viability and strategy for their case.

Pfizer's Liability in Depo-Provera Cases

Pfizer, the manufacturer of Depo-Provera, is facing lawsuits alleging failure to warn users about the risk of brain tumors linked to their contraceptive injection.

As of 2025, multiple cases have been filed, particularly concerning the development of meningiomas. These Depo-Provera lawsuit filed actions highlight claims against Pfizer and other manufacturers for their failure to disclose the risks associated with long-term use of Depo-Provera, despite existing scientific evidence.

The lawsuits claim that Pfizer was negligent in informing patients about the potential long-term risks associated with using Depo-Provera.

While the legal battles continue, the link between Depo-Provera and brain tumors, as well as Pfizer’s responsibility, is being scrutinized in court alongside ongoing Transvaginal Mesh Lawsuit issues.

Factors Contributing to Pfizer’s Liability

Pfizer’s liability in cases related to Depo-Provera and Transvaginal Mesh primarily stems from allegations of inadequate warnings regarding health risks. The ongoing Depo-Provera litigation highlights various legal developments, including bellwether trials aimed at evaluating jury responses to evidence linking the contraceptive to serious health risks like brain tumors. Significant settlements achieved in related cases and the potential transition to multidistrict litigation (MDL) to efficiently handle numerous individual claims against the manufacturers further underscore the broader legal context.

The lawsuits argue that for years, Depo-Provera users were not properly informed about the increased likelihood of developing brain tumors.

Investigations and lawsuits have revealed that using Depo-Provera can significantly elevate the risk of meningiomas, a type of brain tumor, especially with long-term use.

Consequently, Pfizer’s failure to provide sufficient warning is seen as a breach of their duty of care to consumers.

The key factors contributing to this liability include:

  • Failure to Warn: Pfizer allegedly did not adequately inform users about the risks of brain tumors.
  • Negligence in Communication: A lack of proper communication regarding potential side effects over long-term use.
  • Scientific Evidence: Studies indicate a significant correlation between Depo-Provera use and increased tumor risk.
  • Regulatory Scrutiny: Ongoing examinations by health authorities and legal entities.

Pfizer’s approach towards labeling and communicating health risks has come under intense focus.

The legal community and plaintiffs argue that, had there been clearer warnings, many could have avoided using Depo-Provera or switched to alternative methods sooner.

Discussions around the responsibility for adequate consumer safety information continue to be central to these lawsuits.

The outcomes of such cases may have broader implications for pharmaceutical companies regarding product transparency and consumer protection.

Potential Settlement Amounts in Depo-Provera Brain Tumor Lawsuits

Settlement amounts in Depo-Provera related brain tumor lawsuits are influenced by various factors, including the severity of the condition and the degree of negligence attributed to Pfizer.

Legal proceedings are showing that plaintiffs seek significant compensation due to the health complications experienced. The establishment of a Depo Provera MDL (Multidistrict Litigation) has been crucial in handling these cases efficiently while maintaining the individuality of each plaintiff’s claim.

Moreover, the emotional and economic burdens borne by victims and their families are often reflected in these settlements.

Although precise amounts vary, the expectation is for substantial settlements to be reached in 2025.

Potential settlement amounts in these lawsuits may include:

  • Medical Expenses: Reimbursements for all medical treatments related to the brain tumor.
  • Lost Wages: Compensation for income lost due to inability to work.
  • Pain and Suffering: Damages for physical and emotional distress suffered by the plaintiff.
  • Punitive Damages: Additional sums meant to punish Pfizer for neglect.

As lawsuits proceed through the courts, legal experts anticipate that the final settlement figures will serve as precedents for future pharmaceutical litigations.

The impact of these settlements transcends mere financial compensation, emphasizing the importance of corporate accountability.

For plaintiffs, achieving a settlement is not only about resolving current grievances but also potentially protecting future consumers from similar issues.

These cases underscore the vital role of the legal system in mediating disputes between individuals and large corporations, particularly in health-related matters.

    Depo-Provera lawsuit claims allege that Pfizer (the manufacturer of Depo-Provera) failed to adequately warn consumers about potential risks and complications associated with long-term use of the contraceptive injection.

  • What are the main health risks linked to Depo-Provera use?

    Recent studies have identified serious health complications associated with the injectable contraceptive Depo-Provera, including a 555% increased risk of developing brain tumors (meningiomas).

    Other significant risks include bone density loss, osteoporosis, increased fracture risk, blood clots, and depression.

    These risks may increase with longer duration of use and can potentially persist after discontinuing the medication.

  • Who qualifies for filing a Depo-Provera lawsuit?

    To qualify for a Depo-Provera lawsuit, you must have received at least two Depo-Provera injections and developed a meningioma or related brain tumor.

    You’ll need medical documentation that establishes a link between your prolonged Depo-Provera use and the development of the tumor.

    The lawsuit must also be filed within your state’s legal time limits.

    Consultation with a specialized attorney can help determine your eligibility.

  • What is the basis for the Depo-Provera lawsuits against Pfizer?

    The lawsuits against Pfizer primarily allege that the company failed to adequately warn users about the risk of developing meningioma brain tumors.

    A 2024 British Medical Journal study showed that Depo-Provera users face a significantly higher risk of meningiomas compared to non-users.

    Plaintiffs claim Pfizer knew or should have known about these risks but failed to properly inform patients and healthcare providers. They argue that a thorough review of patients’ medical history, particularly those with prolonged use of hormone-based medications like Depo-Provera, could have established a clearer link between the medication and the development of meningiomas.

  • What compensation can be expected from a Depo-Provera lawsuit?

    Compensation in Depo-Provera lawsuits may cover medical expenses, lost wages, pain and suffering, and potentially punitive damages.

    The settlement amounts vary based on factors such as the severity of the condition, extent of medical treatments required, and impact on quality of life. As an alternative contraceptive option, Depo-SubQ Provera is often highlighted for its reduced concentration of progestin and shorter duration in the body, which some argue underscores potential negligence by the manufacturer in failing to adequately warn about the risks associated with the original drug.

    While specific amounts aren’t predetermined, settlements aim to address both economic and non-economic damages suffered by victims.

  • How are brain tumors (meningiomas) related to Depo-Provera use?

    Scientific studies have revealed that Depo-Provera use significantly increases the risk of developing meningiomas, which are tumors that grow in the protective layers surrounding the brain and spinal cord.

    While typically benign, these tumors can cause serious health complications due to their location and potential pressure on brain structures, leading to various neurological symptoms.

  • What historical warnings existed about Depo-Provera risks?

    Before recent brain tumor findings, Pfizer’s warnings primarily focused on bone health risks, including increased risk of osteoporosis and bone density reduction.
