Question: What is the lawsuit against the Depo Shot?

Answer: The lawsuit against the Depo Shot (Depo-Provera) alleges that Pfizer failed to warn users about the increased risk of meningiomas associated with long-term use of their birth control drug.

Studies have shown that using Depo-Provera for over a year can increase the risk of developing meningiomas by up to 5.6 times.

Plaintiffs are seeking compensation for medical expenses, lost wages, and pain and suffering resulting from Pfizer’s alleged negligence in not disclosing these serious health risks.

Individual claims have been filed nationwide against Pfizer Inc., the manufacturer of Depo-Provera, and other associated entities.

On this page, we’ll discuss this question in further depth, an overview of the Depo-Provera lawsuit, steps to file a Depo-Provera shot lawsuit, and much more.

Investigating the Lawsuit Against the Depo Shot

The basis of these legal actions focuses on the manufacturer’s negligence and failure to adequately disclose the risks of developing brain tumors to plaintiffs using the Depo Provera shot.

A study published in the British Medical Journal found that women injected with medroxyprogesterone acetate (the active ingredient in Depo-Provera shots) had a 5.6-fold higher risk of developing meningiomas (brain tumors).

The defendants named in these lawsuits include:

  • Pfizer Inc.: The primary manufacturer and marketer of Depo-Provera.
  • Viatris Inc.: A global healthcare company producing and distributing pharmaceuticals, including generic versions of Depo-Provera.
  • Greenstone LLC: A subsidiary of Pfizer responsible for manufacturing generic pharmaceutical products.
  • Prasco Laboratories: A pharmaceutical company that markets authorized generic versions of brand-name drugs.
  • Pharmacia & Upjohn Company LLC: A legacy company now part of Pfizer, historically involved in developing and distributing Depo-Provera.

The litigation is still in the early stages, with more lawsuits expected to be filed as awareness of the potential link between Depo-Provera and brain tumors increases.

If you or a loved one developed severe health conditions after receiving Depo-Provera injections, you may be eligible to seek compensation.

What is the Lawsuit Against the Depo-Provera Shot?

The lawsuit against the Depo-Provera shot centers on claims that the birth control injection, manufactured by Pfizer, has led to severe and lasting health complications for some users.

Plaintiffs argue they were not adequately warned about the risks of taking Depo-Provera.

Known Side Effects of Depo-Provera

The Depo-Provera shot has been linked to a variety of side effects, some of which may have serious long-term consequences for users.

Individuals who have received this contraceptive injection may experience the following:

  • Bone Density Loss: Depo-Provera has been associated with significant bone density reduction, which may increase the risk of fractures and osteoporosis, particularly with prolonged use.
  • Mental Health Issues: Some users report mood swings, depression, and anxiety after starting Depo-Provera, which can impact daily functioning and quality of life.
  • Menstrual Irregularities: Many users experience changes in menstrual cycles, including irregular periods, amenorrhea (absence of menstruation), or prolonged bleeding.
  • Weight Gain: Significant weight gain has been noted among users, which can contribute to additional health concerns, such as metabolic issues.
  • Hair Loss and Skin Changes: Some users report thinning hair or increased acne, which may affect self-esteem and emotional well-being.

These side effects vary widely in intensity, with some users experiencing only minor symptoms while others face more severe, life-altering health impacts.

As litigation progresses, affected individuals are seeking compensation for medical costs, pain and suffering, and other damages associated with the side effects of this birth control shot.

Research and Scientific Studies in the Depo-Provera Lawsuits

Extensive research and scientific studies have explored the potential health risks associated with Depo-Provera, with findings suggesting significant concerns for long-term users.

The data collected from various studies have raised alarms about potential links between Depo-Provera use and serious medical conditions, including bone density loss and neurological impacts.

Plaintiffs in these lawsuits cite this growing body of research to argue that they were not adequately warned about severe risks, including the possibility of brain tumors and other life-altering complications.

These scientific findings are critical to ongoing legal arguments that aim to hold the manufacturer accountable for any associated harm.

Depo-Provera Brain Tumor Risk

Recent scientific studies indicate a possible association between Depo-Provera use and an increased risk of certain types of brain tumors.

Though more research is needed to establish causation conclusively, studies have found that users of progestin-based contraceptives, like Depo-Provera, may face a higher risk of developing brain tumors such as meningiomas.

Meningiomas are typically benign but can lead to severe complications, including headaches, vision changes, and neurological deficits, particularly if they grow or are located near critical areas of the brain.

The presence of progestin, a hormone in Depo-Provera, is thought to stimulate meningioma growth in individuals predisposed to these tumors.

Findings from studies linking Depo-Provera to brain tumor risks include:

  • Meningioma Development: Evidence suggests a possible link between long-term Depo-Provera use and the growth of meningiomas, especially in high-dose or extended-use cases.
  • Hormone Influence: Hormone progestin in Depo-Provera may act as a growth factor for brain cells, increasing the likelihood of meningioma formation in susceptible individuals.
  • Patient Reports: Some patients have reported neurological symptoms after prolonged use of Depo-Provera, which may be related to tumor development.
  • Increased Risk with Duration: Data shows that prolonged Depo-Provera use correlates with an elevated likelihood of tumor-related complications.
  • Medical Studies: Studies published in recent years support further investigation into the link between progestin-based contraceptives and brain tumor formation.

Although a definitive cause-and-effect relationship has yet to be proven, the association between Depo-Provera and meningiomas is becoming a pivotal area in litigation.

Depo-Provera lawyers argue that had they been informed of this risk, then plaintiffs may have opted for alternative forms of contraception.

Other Severe Health Risks Depo-Provera Patients Face

In addition to the potential brain tumor risk, Depo-Provera has been linked to various other severe health risks that can significantly impact a patient’s quality of life.

Long-term users of the drug report conditions that affect their bone health, cardiovascular health, and even metabolic balance.

These severe risks have led to heightened scrutiny of the contraceptive injection Depo Provera in medical and legal circles, with numerous studies suggesting that the risks may outweigh the benefits for some patients.

Some of the major health risks associated with Depo-Provera include:

  • Bone Density Reduction: Extensive studies reveal that Depo-Provera can lead to decreased bone mineral density, elevating the risk of osteoporosis and fractures.
  • Cardiovascular Risks: Certain studies have shown that Depo-Provera may contribute to an increased risk of blood clots, hypertension, and related cardiovascular events.
  • Increased Cancer Risk: Research has pointed to a possible link between Depo-Provera and certain cancers, including cervical and breast cancer, although findings remain inconclusive.
  • Severe Mood Changes: Users may experience significant mood swings, depression, or anxiety, potentially requiring medical intervention.
  • Immune System Impact: Some reports indicate that Depo-Provera may affect immune function, leaving users more susceptible to infections.

These health risks underscore the importance of thorough medical counseling before using Depo-Provera birth control, especially for patients who may have predisposing factors for these conditions.

The lawsuit argues that Depo-Provera’s manufacturer failed to provide adequate warnings and research to ensure patient safety.

If you or a loved one developed severe health conditions after receiving Depo-Provera injections, you may be eligible to seek compensation.

Manufacturers of Depo-Provera Named in the Lawsuits

As Depo-Provera lawsuits continue to grow, an expanding list of defendants includes companies involved in the drug’s manufacturing, marketing, and distribution.

The primary manufacturers and distributors named in federal lawsuits include:

  • Pfizer Inc.: As the principal manufacturer of Depo-Provera, Pfizer is the primary defendant.
  • Viatris Inc.: Following the merger of Mylan and Upjohn (a Pfizer subsidiary), Viatris is implicated in certain lawsuits due to its role in the production and distribution of Depo-Provera and its generic equivalents.
  • Greenstone LLC: A Pfizer subsidiary, Greenstone manufactures authorized generic versions of Depo-Provera.
  • Prasco Laboratories: As an authorized generic distributor, Prasco faces allegations of distributing Depo-Provera generics without adequate risk warnings, contributing to patients’ lack of informed consent.
  • Pharmacia & Upjohn Company LLC: A Pfizer subsidiary involved in the early development and marketing of Depo-Provera, Pharmacia & Upjohn has also been named in some lawsuits.

Federal Lawsuits Filed Nationwide

Numerous federal lawsuits have been filed across the U.S., with plaintiffs pursuing claims against Depo-Provera’s manufacturers in states including California, Indiana, and Texas.

The following are notable individual claims filed in federal courts against Depo-Provera manufacturers:

  • Schmidt v. Pfizer Inc. et al.: Filed in the Central District of California, this lawsuit alleges that prolonged Depo-Provera use led the plaintiff to develop a meningioma, necessitating brain surgery.
  • Noble v. Pfizer Inc. et al.: In this case, the plaintiff claims that 20 years of Depo-Provera use caused a brain tumor diagnosed in 2017, which required surgery and radiation treatment. The plaintiff reportedly continued using Depo-Provera, unaware of its possible link to her condition.
  • Monique Jones v. Pfizer Inc. et al.: Filed in the Central District of California, Jones asserts that her Depo-Provera use from 2000 to 2024 led to an intracranial meningioma diagnosis in 2020. Due to the tumor’s location, surgery was deemed too risky, leaving her with persistent symptoms.
  • Kathleen Fazio v. Pfizer Inc. et al.: Another case in the Central District of California, this lawsuit claims that Fazio’s nearly 25-year use of Depo-Provera resulted in a calcified meningioma, diagnosed in 2020. Surgical removal was considered too dangerous, resulting in chronic pain and ongoing complications for Fazio.
  • Unnamed Plaintiff in Texas: Filed in the Southern District of Texas, this lawsuit alleges that Depo-Provera use led to the development of a brain tumor.

With similar claims emerging by Depo-Provera users across various federal courts, these cases may be consolidated into a multi-district litigation (MDL) to streamline the legal process.

Consolidation through MDL allows for shared handling of evidence and witness testimony, which can increase efficiency and consistency in addressing plaintiffs’ claims nationwide.

If you or a loved one developed severe health conditions after receiving Depo-Provera injections, you may be eligible to seek compensation.

Steps to File a Depo-Provera Shot Lawsuit

If you or a loved one have experienced severe health complications due to Depo-Provera use, filing a lawsuit may provide an opportunity to seek compensation for medical expenses, lost wages, and other damages.

Legal action involves several steps, including assessing eligibility and gathering evidence to strengthen your claim.

Eligibility Criteria for Plaintiffs

To qualify for filing a Depo-Provera lawsuit, plaintiffs must meet specific criteria to demonstrate that their health complications are directly linked to the contraceptive shot.

Plaintiffs should generally consider the following eligibility factors:

  • Prolonged Use: Many claims involve long-term use of Depo-Provera, as extended exposure is often associated with more severe side effects, such as bone density loss or brain tumors.
  • Documented Health Complications: Eligible plaintiffs typically must provide medical records showing they have been diagnosed with conditions like meningiomas, osteoporosis, or other serious health issues linked to Depo-Provera.
  • Timeliness: Meeting the statute of limitations is essential, as plaintiffs must file within the allowable period following their diagnosis or discovery of harm.
  • Physician Documentation: Having medical professionals confirm that the condition is potentially linked to Depo-Provera use can support the credibility of a claim.
  • Demonstrated Impact on Daily Life: Showing how the health issue has disrupted work, daily activities, or quality of life may strengthen the case.

Meeting these criteria can improve the strength of your lawsuit and demonstrate that Depo-Provera’s side effects substantially impact your health.

Consulting with an experienced product liability lawyer at TruLaw can provide an instant case evaluation and additional guidance on building a case.

Gathering Evidence for Your Claim

Building a strong Depo-Provera lawsuit involves compiling comprehensive evidence to establish a link between Depo-Provera use and your health complications.

Evidence gathering is a critical step, as it forms the foundation of your case and can significantly influence the outcome.

To prepare for your claim, gather the following key evidence:

Frequently Asked Questions

  • What is the main reason for the lawsuit against Depo-Provera?

    The lawsuit against Depo-Provera primarily alleges that prolonged use increases the risk of developing meningiomas (brain tumors). Studies show women injected with the active ingredient had a 5.6-fold higher risk of developing these brain tumors.

  • Who are the main defendants in the Depo-Provera lawsuits?

    Pfizer Inc. is the primary defendant as the main manufacturer of Depo-Provera, along with other companies, including Viatris Inc., Greenstone LLC, and Prasco Laboratories.

    These companies manufacture and distribute both brand-name and generic versions of the drug.

  • What is the statute of limitations in the Depo Provera lawsuit?

    The Depo-Provera lawsuit statute varies by state, typically ranging from one to six years.

    This period generally begins either from the date of injury or from when the plaintiff reasonably became aware of the connection between Depo-Provera use and the development of a brain tumor or other serious health condition.

  • Is there a Depo-Provera Class Action Lawsuit?

    No, there is no current Depo-Provera class action lawsuit.

    Instead, individual claims are being filed in federal courts nationwide.

    This increase in individual claims may eventually lead to the consolidation of cases into a mass tort or multidistrict litigation (MDL), where each plaintiff’s claim is treated individually within a coordinated legal process.

    Unlike a class action, where plaintiffs are grouped into a single lawsuit with a shared outcome, mass torts allow each claim to be evaluated based on its unique circumstances and damages.

  • Is Depo-Provera (Depo-SubQ Provera) banned in the US?

    In 1978, the FDA refused the request of Depo-Provera’s manufacturer, the Upjohn Company, to approve the drug for contraception in the U.S.

    However, it was approved and used for treatment of endometrial and renal cancer during that time.

    After further studies and evaluations, the FDA approved Depo-Provera for contraceptive use in 1992.

    Therefore, while it was not banned, its approval for contraceptive purposes was delayed due to earlier safety concerns.
