Overview of the Depo-Provera Lawsuit

Depo-Provera, a popular injectable contraceptive manufactured by Pfizer Inc., is currently at the center of a growing number of lawsuits.

These legal actions are primarily focused on allegations that the drug increases the risk of developing brain tumors, specifically meningiomas.

On this page, we will discuss an overview of the Depo-Provera Lawsuit, new research linking Depo-Provera to brain tumors in women, who may qualify for the Depo-Provera Lawsuits, and much more.

Lawyers Are Currently Investigating Depo-Provera Lawsuits

Lawyers across the United States are actively investigating and accepting cases related to Depo-Provera use and subsequent brain tumor diagnoses.

These investigations are in the early stages, with attorneys gathering evidence and assessing potential claims.

Depo-Provera Lawsuit

Key points about the current state of Depo-Provera lawsuits include:

  • Recent Scientific Evidence: The lawsuits are largely based on a March 2024 study published in the British Medical Journal (BMJ), which found that women injected with medroxyprogesterone acetate, the active ingredient in Depo-Provera, had a 5.6-fold higher risk of developing meningioma.
  • Failure to Warn: The primary legal claim is that Pfizer failed to adequately warn users and healthcare providers about the potential risk of brain tumors associated with Depo-Provera use.
  • Eligibility Criteria: Individuals who have used Depo-Provera or its generic form at least two (2) times and later developed a meningioma or another type of brain tumor may qualify to file a lawsuit.
  • Early Stages: These cases are still in the early phases of litigation. No multidistrict litigation (MDL) has been formed, and there have been no settlements or jury verdicts yet.
  • Potential for Consolidation: Given the widespread use of Depo-Provera, with approximately 24.5% of sexually active women having used it at some point (according to the CDC’s 2023 National Health Statistics Report), there is potential for these cases to be consolidated in federal court in the future.

As the litigation develops, more information about the scope and potential outcomes of these lawsuits is expected to emerge.

If you or a loved one has been diagnosed with a meningioma or another brain tumor potentially tied to Depo-Provera use, you may qualify to pursue legal action.

Depo-Provera Lawsuit Investigation

Lawyers across the United States are actively investigating potential lawsuits against Pfizer, the manufacturer of Depo-Provera, due to the alleged link between the contraceptive injection and an increased risk of brain tumors, specifically meningiomas.

What Do the Depo Provera Lawsuits Claim?

The most recent Depo-Provera legal claims include various allegations against Pfizer.

The current Depo-Provera lawsuits primarily claim that:

  1. Pfizer failed to adequately warn Depo-Provera users and healthcare providers about the increased risk of developing brain tumors, particularly meningiomas, associated with long-term use of Depo-Provera.
  2. The company knew or should have known about these risks but did not conduct sufficient research or provide proper warnings.
  3. Patients suffered serious health complications, including brain tumors, as a result of using Depo-Provera without being fully informed of the risks.
  4. Pfizer may have been negligent in the design, testing, and marketing of Depo-Provera.

Previous Lawsuits Involving the Depo-Provera Birth Control Shot

The Depo-Provera birth control shot has faced multiple lawsuits over the years, with legal actions dating back to the early 2000s.

Previous lawsuits filed in relation to Depo-Provera injectable contraceptive shots include, but are not limited to:

  1. Bone Density Loss Claims: Earlier lawsuits focused on the drug’s link to significant bone mineral density loss. The lawsuits claimed that Pfizer did not sufficiently warn the public about the increased risk of osteoporosis and bone fractures.
  2. FDA Black Box Warning: In 2004, the FDA required Pfizer to include a “black box” warning on Depo-Provera’s label, indicating that extended use may lead to permanent and substantial loss of bone density.
  3. Canadian Class Action: In May 2008, a class action lawsuit was certified in Quebec against Pfizer concerning Depo-Provera, representing a nationwide class.
  4. Settlement: In 2021, Pfizer reached a settlement of over $2 million in a Canadian class action lawsuit concerning side effects related to bone density loss.
  5. Pseudotumor Cerebri Claims: Some lawsuits have also alleged that Depo-Provera could cause a condition called pseudotumor cerebri, which occurs when pressure builds up in the brain.

The new wave of lawsuits focusing on the link between Depo-Provera and brain tumors are still in the early stages, with no multidistrict litigation (MDL) formed yet and no settlements or jury verdicts reported.

If you believe you or a loved one may have developed a brain tumor or meningioma after using Depo-Provera birth control injections, we encourage you to reach out to TruLaw to discuss the specifics of your case.

Recent Developments in the Depo-Provera Litigation

Current Status of Lawsuits Filed

Currently, the Depo-Provera litigation is still in its early stages.

Lawyers across the United States are actively investigating and filing individual lawsuits on behalf of women who developed meningiomas or other brain tumors after using Depo-Provera.

These lawsuits are primarily being filed in state and federal courts against Pfizer, the manufacturer of Depo-Provera.

The number of lawsuits is expected to rise in the coming months as more women learn about the potential connection between Depo-Provera use and brain tumors.

Notable Court Rulings or Developments

While there have been no major court rulings specifically related to Depo-Provera brain tumor cases yet, a few notable developments have occurred:

  1. Scientific Evidence: The March 2024 study published in the British Medical Journal (BMJ) has become a cornerstone of these lawsuits. This study found that women injected with medroxyprogesterone acetate, the active ingredient in Depo-Provera, had a 5.6-fold higher risk of developing meningioma.
  2. Consolidation Efforts: Lawyers representing plaintiffs have begun discussions about potentially consolidating the cases for more efficient handling of pretrial proceedings.
  3. Pfizer’s Response: While Pfizer has not publicly commented on the specific allegations, the company maintains that Depo-Provera’s benefits outweigh its risks when used as directed.

Expectations for Potential Multidistrict Litigation (MDL)

In cases where numerous personal injury claims are filed over the same issue or product, the federal court system allows the consolidation of these cases into a multidistrict litigation (MDL).

If consolidation efforts for Depo-Provera Lawsuits are undertaken, it could mean a more systematic approach for victims to advocate for proper compensation.

An MDL would centralize all federal Depo-Provera lawsuits before a single judge for coordinated pretrial proceedings, including discovery and potential settlement negotiations.

Key points regarding a potential MDL include, but are not limited to:

  1. Timing: While no formal motion has been filed yet, legal experts expect a request for MDL formation to be submitted to the Judicial Panel on Multidistrict Litigation (JPML) within the next 6-12 months.
  2. Location: The location of a potential Depo-Provera MDL is yet to be determined, but it would likely be in a federal court where a large number of cases have been filed or where Pfizer has an established presence.
  3. Benefits: An MDL could streamline the litigation process, reduce costs for all parties involved, and potentially lead to faster resolutions through bellwether trials or global settlements.
  4. Challenges: Establishing general causation between Depo-Provera use and meningiomas may present a notable challenge in these cases, and the outcome of any scientific disputes could strongly impact the direction of the litigation.

As the Depo-Provera litigation continues to evolve, more developments are expected in the coming months.

Potential plaintiffs and their attorneys are closely monitoring the situation for any updates that could impact their cases.

If you or a loved one have used Depo-Provera birth control injections and subsequently developed a meningioma or other brain tumor, you may be eligible to seek compensation through a Depo-Provera lawsuit.

Depo-Provera Injections Potentially Linked to Increased Risk of Cancer and Other Health Issues

What is the Depo-Provera Shot and How Does it Work?

Depo-Provera is an injectable birth control method that uses medroxyprogesterone acetate, a man-made version of the hormone progesterone.

The shot is typically administered every (12) weeks and works by:

  • Preventing ovulation
  • Thickening cervical mucus to block sperm
  • Thinning the uterine lining to prevent implantation

Common Uses of Depo-Provera

Depo-Provera is prescribed to patients for a variety of use cases.

Of these use cases, Depo-Provera is most commonly used for:

  • Contraception (birth control)
  • Treatment of endometriosis-associated pain
  • Management of abnormal uterine bleeding

What are the Problems and Side Effects Linked to Taking Depo Provera?

While Depo-Provera is an effective contraceptive, it has been associated with several side effects and potential health risks.

Side effects and potential health risks linked to Depo-Provera include, but are not limited to:

New Research Links Depo-Provera to Brain Tumors in Women

An important development in Depo-Provera research came from a March 2024 study published in the British Medical Journal (BMJ).

Key findings include:

  • Women using medroxyprogesterone acetate (Depo-Provera) for more than a year had a 5.6-fold higher risk of developing intracranial meningioma.
  • The study examined data from 18,061 women who had surgery for meningioma between 2009 and 2018.
  • Although 92.3% of these meningiomas were benign, they can still lead to serious complications by impacting surrounding brain tissue, nerves, and blood vessels.
  • Two additional progestogen-based medications, medrogestone and promegestone, were likewise linked to a higher risk of meningioma, with increases of 4.1-fold and 2.7-fold, respectively.
  • The authors determined that extended use of medrogestone, medroxyprogesterone acetate, and promegestone raised the risk of developing intracranial meningioma.

In response to these findings, Pfizer, the manufacturer of Depo-Provera, is working with regulatory authorities to update product labels and patient information regarding this potential risk.

This recent research has led law firms to begin accepting cases from women who repeatedly used Depo-Provera and subsequently developed meningiomas.

It’s important to note that while this study shows a correlation, it does not definitively prove causation.

If you or a loved one has been diagnosed with a brain tumor or meningioma after using Depo-Provera birth control injections, you may be eligible to file a claim for compensation.

We encourage you to reach out to us with any questions about your potential case.

Our team is here to guide you through the process — you can use the chat on this page for an instant case evaluation to quickly determine if you qualify to file a Depo-Provera lawsuit.

Do You Qualify for the Depo-Provera Shot Lawsuit?

To determine if you qualify for a Depo-Provera lawsuit, you must meet specific criteria related to your use of the birth control medication and subsequent health issues.

Eligibility Criteria in the Depo-Provera Lawsuit

To qualify for a Depo-Provera lawsuit, potential claimants must meet specific requirements that establish a connection between their use of the medication and their health condition.

To be eligible for a Depo-Provera lawsuit, you generally must meet the following criteria:

  1. Depo-Provera Usage: You must have used brand-name Depo-Provera, Depo-SubQ Provera 104, or an authorized generic version of medroxyprogesterone acetate.
  2. Frequency: You must have received at least two injections of Depo-Provera or its authorized generic version.
  3. Timing: You must have used Depo-Provera or its authorized generic version any time after 1992.
  4. Diagnosis: You must have been diagnosed with a meningioma or another type of brain tumor after using Depo-Provera.
  5. Causation: The brain tumor diagnosis must have occurred after starting Depo-Provera use.

It’s worth noting that individuals who used Depo-Provera for extended periods might have stronger legal claims compared to those who used it only a handful of times.

The criteria above is strictly intended to give you an idea of factors that may be weighed when determining your eligibility for a Depo-Provera lawsuit — this should not be taken as a guarantee that you will qualify to file a claim or as legal advice.

Depo-Provera Lawsuit Statute of Limitations and Deadlines

To ensure your right to file a lawsuit is preserved, it’s important to seek legal advice as soon as you notice any side effects that could potentially be linked to your usage of Depo-Provera.

The statute of limitations for filing a Depo-Provera lawsuit differs by state and can greatly affect your ability to pursue legal action:

  1. Time Limits: Depending on your state, the statute of limitations could be as short as two (2) years from when the side effects of Depo-Provera became noticeable or reasonably should have been noticed.
  2. Discovery Rule: In some states, the statute of limitations may begin when you discovered or reasonably should have discovered the link between Depo-Provera and your brain tumor.
  3. Urgency: It’s important to contact an attorney promptly after a diagnosis to ensure you don’t miss the deadline for filing a claim.
  4. State Variations: The specific time limit can vary widely from state to state, so it’s important to consult with a lawyer who is knowledgeable about the laws in your jurisdiction.
  5. Exceptions: Some states may have exceptions that extend the statute of limitations under certain circumstances, such as for minors or in cases of fraudulent concealment.

Given the detailed nature of these time limits and the potential for variations based on individual circumstances, it’s strongly advised to consult with an experienced Depo-Provera lawsuit attorney as soon as possible.

Process for Filing a Depo-Provera Lawsuit

Pursuing a Depo-Provera lawsuit involves carefully following several key steps — this can help ensure your case is strong and increase your chances of a successful claim.

Hire an Experienced Product Liability Lawyer

The first and most important step in filing a Depo-Provera lawsuit is to hire an experienced product liability lawyer.

Here’s why this is important:

  • Expertise: Product liability cases, particularly those involving pharmaceuticals, can be challenging. An experienced lawyer will be familiar with the details and subtleties of these cases.
  • Resources: Established law firms have the resources to thoroughly investigate your claim and build a strong case.
  • Negotiation Skills: Your lawyer will be able to negotiate effectively with Pfizer’s legal team.
  • No Upfront Costs: Most product liability lawyers work on a contingency fee basis, meaning you don’t pay unless you win your case.

Depo-Provera Brain Tumor Lawsuit Settlement and Payout Amounts

When it comes to estimating potential settlement amounts for Depo-Provera brain tumor lawsuits, it’s important to recognize that this litigation is still in the very early stages.

As a result, any projections about possible compensation remain uncertain at this time.

We still need to determine whether the scientific evidence linking Depo-Provera to brain tumors will be considered admissible in court.

However, we can make an educated guess based on similar tort cases that involve comparable injuries and facts.

It’s important to note that the projections discussed below are strictly to give affected individuals a general idea of what these settlement values could end up looking like if claims are successful — as the litigation progresses, more accurate estimates may become possible.

Depo-Provera Lawsuit Settlement Predictions

If the causation evidence stands up in court, lawyers believe that successful Depo-Provera brain tumor cases involving significant complications could potentially have a settlement value ranging from $100,000 to $500,000.

These estimates should not be taken as a guarantee and actual settlement amounts in successful Depo-Provera claims may vary substantially based on a wide variety of factors.

This wide range reflects the different degrees of severity associated with meningiomas.

The symptoms, treatment options, and long-term prognosis for different forms of meningioma can vary greatly based on the grade of meningioma:

Grade I Meningiomas (Non-Cancerous)

Grade I meningiomas are generally less serious and not life-threatening:

  • Classification: Benign meningiomas
  • Rarity: Account for roughly 78-81% of all meningiomas.
  • Aggressiveness: Grade I meningiomas are the least aggressive type, growing slowly with distinct borders.
  • Growth Rate: They tend to grow at a very slow rate compared to higher-grade meningiomas.
  • Invasiveness: Grade I meningiomas typically do not invade surrounding brain tissue.
  • Treatment: Surgery may not be required unless the tumor is causing symptoms or discomfort.

Grade III Meningiomas (Cancerous)

Grade III meningiomas are much more dangerous and could be life-threatening:

  • Classification: Anaplastic or malignant meningiomas
  • Rarity: They are relatively rare, accounting for only about 1-4% of all meningiomas.
  • Aggressiveness: Grade III meningiomas are the most aggressive and fastest-growing type of meningioma.
  • Growth Rate: They grow and spread quickly compared to lower-grade meningiomas.
  • Invasiveness: These tumors tend to invade surrounding brain tissue and have a high likelihood of recurring after treatment.
  • Treatment: Due to their aggressive nature, Grade III meningiomas typically require more intensive treatment, often involving a combination of surgery and radiation therapy.

Other Factors

Other factors that may influence settlement amounts include, but are not limited to:

  • Duration of Depo-Provera use
  • Age of the plaintiff
  • Impact on quality of life and ability to work
  • Strength of evidence linking Depo-Provera to the tumor

It’s still too early to predict how many cases will fall into each of these categories, but some attorneys expect that Depo-Provera cases involving Grade III meningiomas could lead to substantial compensation.

If these cases go to trial, some settlements could reach millions of dollars.

While a global settlement might not result in average payouts at this level, it’s possible that some individual cases could settle for over $1 million, depending on how this litigation unfolds.

Another factor to consider is that Pfizer, the manufacturer of Depo-Provera, is a company valued at over $150 billion.

With its recent profits, Pfizer has the financial resources to support substantial settlements if necessary.

Unlike some other mass tort cases where a defendant’s ability to pay is a concern, this isn’t an issue in the Depo-Provera litigation.

Comparison to Similar Litigations

Previous settlements in cases with comparable injuries can also help provide a benchmark for potential outcomes in Depo-Provera litigation.

To provide context, we can look at settlements in other pharmaceutical cases involving similar injuries:

Timeline for Settlements

Given the early stage of the litigation, it may be several years before any settlements are reached.

Typically, pharmaceutical mass tort cases follow this general timeline:

  1. Notice of public issue
  2. Lawyers investigate allegations being made in claims
  3. Initial lawsuits are filed
  4. Cases consolidated into multidistrict litigation (MDL)
  5. Discovery phase and pretrial proceedings
  6. Bellwether trials to test the strength of claims
  7. Global settlement negotiations

Frequently Asked Questions

  • Who is the manufacturer of Depo Provera?

    Pfizer Inc. is the current manufacturer of Depo-Provera, a popular long-acting reversible contraceptive (LARC).

    The drug was initially developed by Upjohn, a pharmaceutical company that eventually merged with Pharmacia and was subsequently acquired by Pfizer in 2003.

  • Have Depo-Provera products been proven to be dangerous?

    While Depo-Provera is FDA-approved, it has been associated with some serious side effects.

    Studies have linked its use to bone density loss and an increased risk of meningioma brain tumors.

    To address these concerns, the FDA added a black box warning about bone density loss in 2004.

  • Has Pfizer issued any warnings or recalls related to Depo-Provera and brain tumors?

    Pfizer has not issued any specific recalls related to brain tumors in Depo-Provera.

    However, at the FDA’s request, the company added a black box warning to the drug’s label in 2004 to highlight the potential risk of bone density loss with prolonged use.

  • What are the exclusions or disqualifying factors that might prevent me from filing a Depo-Provera lawsuit?

    Several factors could disqualify you from filing a Depo-Provera lawsuit.

    These include, but are not limited to:

    • Not using brand-name Depo-Provera: Generic alternatives might not be included in legal actions.
    • Using it fewer than two times: Limited exposure might not be sufficient.
    • Using it before 1992: The drug’s formulation changed in 1992, which could affect legal claims.
    • Not being diagnosed with meningioma: The lawsuit is specifically related to this type of brain tumor.
    • Falling outside your state’s statute of limitations: There are time limits for filing legal claims.

  • What are the Serious Side Effects of Depo Provera Injections?

    Depo-Provera can have serious side effects, including but not limited to:

    • Bone density loss: Long-term use can lead to weakened bones.
    • Increased risk of meningioma brain tumors: Studies have linked Depo-Provera to a higher risk of this type of tumor.
    • Blood clots: There’s a slightly increased risk of blood clots, especially in the legs and lungs.
    • Liver problems: In rare cases, Depo-Provera can cause liver damage.
    • Ectopic pregnancy: While rare, there’s a slightly increased risk of ectopic pregnancy if conception occurs while using Depo-Provera.
    • Severe allergic reactions: Some individuals may experience severe allergic reactions to the medication.

  • What are the Minor Side Effects of Depo Provera?

    Depo-Provera can cause many common minor side effects, including but not limited to:

    • Irregular menstrual bleeding: This is a common side effect, especially during the first few months of use.
    • Weight gain: Certain individuals might notice an increase in weight.
    • Headaches: Headaches can occur in some users.
    • Mood changes: Mood swings or changes in emotional state are possible.
    • Decreased sex drive: A lower sex drive is a potential side effect.
    • Breast tenderness: Breast sensitivity or tenderness may occur.

    These minor side effects often improve over time as the body adjusts to the hormone.

    If you experience any side effects that are bothersome or persist, it’s important to consult with your healthcare provider.

  • How Many Women Receive the Depo Shot Regularly?

    Approximately 2 million women in the United States regularly receive the Depo-Provera shot.

    This makes it a popular long-acting reversible contraceptive (LARC) option.

    Globally, injectable contraceptives (including Depo-Provera and other options) are used by around 74 million women.

  • What are the Different Types of Depo Provera Shots?

    There are two (2) primary types of Depo-Provera:

    1. Traditional Depo-Provera (150 mg): This is an intramuscular injection administered every 12-14 weeks.
    2. Depo-subQ Provera 104 (104 mg): This is a lower-dose subcutaneous injection, also administered every 12-14 weeks.

    Both options offer effective birth control but may have different side effect profiles.

  • How Does the Depo Provera Birth Control Shot Work?

    Depo-Provera works by releasing the hormone progestin, which prevents pregnancy in three (3) ways:

    1. Suppresses ovulation: This means the ovaries don’t release an egg each month.
    2. Thickens cervical mucus: This creates a barrier that blocks sperm from reaching the egg.
    3. Thins the uterine lining: This makes it less likely for a fertilized egg to implant in the uterus.

  • Is there a Depo-Provera Class Action Lawsuit?

    While there is currently no active Depo-Provera class action lawsuit specifically for brain tumor claims, individual lawsuits are being filed.

    Women who have developed meningiomas after using Depo-Provera are pursuing legal action.

    These cases are currently in their early stages, and attorneys are investigating potential claims.

    There’s a possibility that these individual cases may be consolidated into a multidistrict litigation (MDL) in the future, but this has not occurred yet.

  • What are the primary legal claims in the Depo-Provera brain tumor lawsuits?

    The primary legal claims in Depo-Provera brain tumor lawsuits are failure to warn and product liability.

    Plaintiffs allege that Pfizer, the manufacturer, failed to adequately inform users and healthcare providers about the increased risk of developing meningiomas (brain tumors) associated with prolonged use of Depo-Provera.

    These claims suggest that Pfizer knew or should have known about the risk but failed to take appropriate measures to protect consumers.

  • Are there any studies linking Depo-Provera to brain tumors?

    Yes, there is a study linking Depo-Provera to brain tumors.

    A March 2024 study published in the British Medical Journal (BMJ) found a significant association between long-term use of medroxyprogesterone acetate (the active ingredient in Depo-Provera) and an increased risk of developing intracranial meningioma.

    This study analyzed data from over 18,000 women who underwent surgery for meningioma.
