Latest Legal Developments | Depo Provera Lawsuit (2025)

Depo Sub-Q Provera 104, a lower-dose, subcutaneous alternative to Depo-Provera, is expected to play a key role in upcoming litigation. Delivering 104 mg of medroxyprogesterone acetate per dose versus 150 mg in the original, it offers effective contraception with potentially lower meningioma risks due to reduced synthetic progestin exposure.

Questions arise about Pfizer's hesitancy to promote this safer alternative. Critics suggest profit concerns, as lower doses and extended intervals between injections could reduce revenue. Additionally, the need for training in subcutaneous administration may have been seen as a hurdle.

Lawyers will likely scrutinize Pfizer’s internal discussions and documents during depositions to uncover corporate decision-making behind product prioritization.

A Cypress, California woman and her husband claim Depo-Provera caused multiple intracranial meningiomas after nearly 36 injections over nine years. The plaintiff, who started using the contraceptive in 2015, developed symptoms like blurred vision, leading to a 2024 diagnosis of two brain tumors requiring ongoing medical care. This case, like recent similar lawsuits, was filed in federal court in the Central District of California.

A Crestline, California resident has sued Pfizer, claiming Depo-Provera caused severe neurological injuries, including an intracranial meningioma. The plaintiff used the contraceptive injection from 2015 to 2024 under medical guidance. While the Northern District of California was considered a potential venue for an MDL, the Central District, where this case was filed, remains another viable option.

In a new Depo Provera lawsuit, a Fontana, California woman claims Depo-Provera caused her to develop a life-threatening brain tumor. She says that the companies responsible, including Pfizer, Viatris, and their affiliates, failed to disclose the risks despite decades of scientific evidence linking the drug to meningioma. According to the suit, the plaintiff used Depo-Provera injections from 1999 to 2018, after which she began to suffer neurological symptoms that led to the discovery of a large intracranial meningioma requiring invasive surgery.

Where should a Depo Provera MDL be located? This case was filed in the Northern District of California which is increasingly looking like the best option. If this is how it plays out, any Depo shot lawsuit filed in federal court in Texas, New York, Florida, or anywhere else in the country would be transferred for pretrial handling in California.

Some attorneys are investigating liability claims based on marketing tactics alongside failure-to-warn allegations. They argue that Depo-Provera’s promotional materials downplayed risks, focusing heavily on its advantages while insufficiently highlighting the increased meningioma risk linked to long-term use. These cases often cite consumer protection laws, alleging that Pfizer misled consumers by failing to disclose vital safety information.

The connection between Depo-Provera and the development of meningiomas is thought to be influenced by its high levels of synthetic progestin, which mimics the hormone progesterone. Meningiomas frequently express hormone receptors for progesterone and estrogen, and activation of these receptors by hormones can stimulate tumor growth. Extensive research supports the idea that prolonged exposure to elevated progesterone levels could over-stimulate these receptors, thereby promoting the growth of meningiomas.

Moreover, the risk associated with Depo-Provera appears to be dose-dependent, indicating a dose-response relationship. This means that the risk of developing meningiomas increases with the number of Depo-Provera doses received, which is why legal cases typically do not focus on women who have received only one injection. This pattern of risk is similar to that observed in other hormone-sensitive conditions like breast and uterine cancers, where long-term hormonal exposure is linked to a higher risk.

From a legal standpoint, while it is beneficial to understand and potentially explain the biological mechanisms behind Depo-Provera's link to meningiomas, attorneys do not necessarily need to establish this precise causation in court. The primary objective is to demonstrate a clear association between the use of Depo-Provera and the incidence of meningiomas. However, explaining the mechanism can be advantageous in court, as jurors often seek to understand the underlying reasons for the association, enhancing the credibility of the claims. This understanding also underscores why potential risks should have been more apparent to Pfizer, bolstering the case for negligence in failing to warn users adequately.

Pfizer's labeling for Depo-Provera in the European Union and the United Kingdom introduces warnings about the risk of meningiomas linked to long-term use of the drug. This label change, although a step towards greater transparency, is criticized for its lack of specificity and urgency. The wording advises caution for those with a history of meningioma and calls for discontinuation upon diagnosis, but it does not address the risk for patients without previous history, nor does it proactively inform patients of the potential for developing these tumors.

Plaintiffs' attorneys are highlighting these discrepancies as evidence of Pfizer's negligence, particularly pointing out the difference in how risks are communicated to patients in the EU compared to the U.S. The softer language used in the EU, which lacks forceful directives or preventative guidelines, may be seen as inadequate. This is particularly concerning because it fails to emphasize the severity of the risk or the critical need for vigilance among all patients, not just those with a history of meningioma.

The expectation is that Pfizer will eventually update the U.S. label, but if this update mirrors the EU's vague phrasing, it will likely be deemed insufficient by plaintiffs’ lawyers. They argue that only a strong, clear warning that explicitly outlines the risks and necessary precautions will suffice. Anything less may be considered as virtually no warning at all, potentially exacerbating Pfizer's legal challenges and impacting patient safety negatively. This situation underscores the importance of consistent, transparent, and proactive patient communication regarding pharmaceutical risks.

Depo-Provera lawsuits primarily allege that Pfizer failed to warn consumers about the drug’s risks. Additionally, plaintiffs assert a strict liability design defect, claiming Depo-Provera’s high-dose progestin makes it inherently dangerous and unreasonably unsafe.

Pfizer developed Depo-SubQ Provera 104, a safer, lower-dose alternative administered subcutaneously. By promoting the higher-dose Depo-Provera and not informing the medical community and consumers of the risks, Pfizer is accused of prioritizing market share over safety.

Plaintiffs argue that Pfizer should have marketed the safer Depo-SubQ Provera 104 or redesigned Depo-Provera to reduce health risks. This internal availability of a safer option strengthens the strict liability claim, as it demonstrates that Pfizer had the means to mitigate the dangers without relying on competitor products.

These factors make the design defect claims compelling, highlighting Pfizer’s responsibility for the injuries caused by Depo-Provera’s inherent risks.

Significant usage patterns of Depo-Provera among American women highlight the potential scale of ongoing litigation. The December 2023 National Health Statistics Report reveals that 24.5% of sexually experienced women in the U.S. used Depo-Provera between 2015 and 2019. Usage rates are particularly high among specific demographics, with 27.2% of Hispanic women and 41.2% of Black women utilizing the contraceptive during the same period.

This widespread use indicates that a substantial number of women may be affected and could pursue lawsuits related to Depo-Provera injections. The demographic data clarifies the issue's scope and underscores the importance of addressing these concerns through the legal process.

The disparity in Depo-Provera labeling between the U.S. and Europe highlights significant concerns about patient safety and transparency. In Europe, Pfizer has updated the drug’s label to include warnings about the potential risk of meningiomas, a move prompted by new research and regulatory demands. However, in the U.S., despite existing studies linking hormonal contraceptives to meningiomas, neither Pfizer nor the FDA has introduced a corresponding warning.

This inconsistency not only jeopardizes patient safety but also damages Pfizer’s reputation, suggesting a lack of commitment to transparency in the U.S. market. The urgent need for the FDA to mandate a meningioma risk warning on Depo-Provera in the United States is clear, aiming to align with European standards and ensure informed decision-making for American consumers.

Legal teams are intensifying their investigation into the potential link between Depo-Provera and brain tumors. They are now also examining the risks associated with hormone replacement therapy (HRT), which contains similar hormones. Concerns focus on whether prolonged exposure to these hormones may promote abnormal cell growth in the brain, increasing the risk of meningiomas.

There is a growing demand for comprehensive research to validate the hypothesis that hormone-based therapies like HRT could similarly elevate the likelihood of developing brain tumors. This investigation aims to clarify the extent of these risks and ensure that appropriate measures are taken to protect and inform patients.

Depo-Provera lawyers are fine-tuning eligibility criteria for meningioma lawsuits, focusing on the necessary number of injections to link the drug to tumor development. Due to the dose-response relationship observed between Depo-Provera use and increased meningioma risk, our firm opts for a threshold of at least two injections. This decision rests on two primary considerations:

1. Scientific Ambiguity: Current research does not conclusively determine the minimum number of injections required to induce meningioma. Given this uncertainty, a lower threshold allows more affected women to pursue claims, ensuring broader access to justice.
2. Significant Risk Increase: The key study in this area shows a risk ratio of 5.5, indicating a 450% increase in meningioma risk. This dramatic rise in risk supports the notion that even a minimal exposure—such as two injections—could be substantial enough to establish causality, especially in cases where no other significant risk factors (e.g., radiation exposure or genetic predispositions) are present.

This approach effectively equips plaintiffs with a compelling argument in court, suggesting that Depo-Provera likely represents the critical factor in their meningioma diagnosis, akin to the final missing piece in a nearly complete puzzle.

For women considering Depo-Provera litigation, statute of limitations issues are less daunting due to two key legal principles:

1. Discovery Rule: This rule delays the start of the statute of limitations until the injury and its link to the defendant’s actions are known or should reasonably be known. In Depo-Provera cases, many women could not have connected their meningioma diagnoses to the drug before recent scientific revelations. Previously, the association between Depo-Provera and brain tumors was not widely acknowledged by the medical community or the public, making early discovery of these claims unlikely.
2. Fraudulent Concealment: This legal doctrine may apply if it can be shown that Depo-Provera's manufacturers and marketers intentionally concealed the drug's risks. If the defendants are found to have manipulated labeling, omitted safety warnings, and withheld critical information about the risk of intracranial meningiomas, the statute of limitations may be tolled. This tolling occurs because the defendants' actions would have prevented plaintiffs from becoming aware of the potential claims.

Together, these doctrines provide a robust argument for extending the timeframe in which affected women can file claims, addressing common concerns about meeting legal deadlines in these complex cases.

The experience of being diagnosed with a meningioma is deeply distressing for patients, particularly due to the tumor's potential neurological effects and the emotional turmoil it causes. These tumors, while often benign, can significantly disrupt daily life and mental health. Patients report severe anxiety that affects their cognitive functions and emotional stability, magnifying their suffering.

This anxiety is not just about health but extends to the fear of surgical treatments and their possible complications, such as hematomas, and the ongoing worry about the tumor's recurrence. Research indicates that these emotional disturbances may be exacerbated by hormonal changes linked to the tumor's growth. These factors together frame the pain and suffering arguments in the lawsuits, highlighting the profound impact on the victims' quality of life and their concerns about their future health and well-being.

Nationwide plaintiffs are filing Depo Provera lawsuits in Pennsylvania’s Philadelphia Court of Common Pleas, leveraging its experienced judiciary and expertise in complex mass tort and product liability cases. The court’s Complex Litigation Center efficiently manages large caseloads and consistently rules in favor of plaintiffs.

A strategic advantage is that Viatris Inc., a key defendant, is headquartered in Canonsburg, Pennsylvania. This allows plaintiffs to include all defendants in state court. Pennsylvania’s procedural laws support case consolidation, lowering litigation costs and reducing time. Additionally, the state’s flexible standards for expert testimony strengthen plaintiffs’ scientific evidence.

Philadelphia juries are known for their empathy towards victims of corporate negligence, often awarding substantial verdicts against large corporations. This reputation positively influences settlement negotiations, resulting in more significant offers from defendants like Pfizer.

Meningioma risk is influenced by genetic factors, such as neurofibromatosis type 2 (NF2), Gorlin syndrome, and Li-Fraumeni syndrome, as well as environmental factors like ionizing radiation and elevated hormone levels from contraceptives or HRT. Our firm does not accept claims involving these specific risk factors. Notably, none of the over 150 women who have contacted us fall under these exclusions.

Plaintiffs are pursuing claims against Pfizer for generic Depo-Provera, arguing the company distributed an "authorized generic" through subsidiaries without adequate warnings about meningioma risks. By controlling the generic’s production and marketing, Pfizer is alleged to have retained responsibility for updating safety labels, making it accountable for failing to disclose risks linked to both the brand-name and generic versions of the drug.

Depo-Provera cases are expected to follow a Multidistrict Litigation (MDL) approach instead of a class action, due to the unique injuries involved. MDLs allow individual case evaluations and separate trials if necessary. State-level MDLs may also form in states like Ohio, Pennsylvania, and New York, where defendants are based, streamlining pretrial proceedings while addressing individual claims.

Plaintiffs allege Pfizer’s control over Greenstone, Viatris, and Prasco ties the company to Depo-Provera generics' failure to warn. Despite the generics’ distribution through these subsidiaries, Pfizer’s oversight allegedly included identical formulations and labeling. Lawyers argue Pfizer bears responsibility for inadequate warnings, citing its direct influence and profit from the generics' operations.

A nurse diagnosed with a brain tumor believes progesterone in HRT, Depo-Provera, and IVF treatments caused her condition. Symptoms included headaches and speech comprehension issues. After May 2024 surgery, she is recovering but faces ongoing memory challenges.

Following new evidence linking Depo-Provera to meningioma brain tumors, Pfizer revised the prescribing information and guidelines for the contraceptive. However, the company has not updated the drug's warning label to reflect these findings.

Pfizer has acknowledged the potential risk of meningioma associated with prolonged use of Depo-Provera. The company is working with regulatory agencies to update product labels and patient information leaflets to reflect this risk.

A British Medical Journal study links Depo-Provera to a 5.5x higher risk of meningioma (brain tumor) in users compared to non-users. This strong evidence is likely to speed up litigation against the manufacturer.
