The Moment a Birth Control Shot Becomes a Brain Tumor Diagnosis
We know why you are here. You are likely sitting at a kitchen table with a folder of medical records, or perhaps you are reading this from a hospital bed after a craniotomy. For years, you trusted a three-month injection to be a maintenance-free part of your healthcare. You were told it was safe. Now, you have been diagnosed with a meningioma—a tumor growing in the tissues that cover your brain and spine—and you are realizing that the manufacturer may have known about this risk long before they finally warned you.
This is a crisis of trust as much as a crisis of health. At Attorney911, we believe that when a multi-billion-dollar pharmaceutical company chooses its profit margins over the safety of the women using its products, it must be held answerable. Our trial team takes pharmaceutical injuries personally because we see the human cost behind the clinical data.
If you have been diagnosed with a brain tumor after long-term use of Depo-Provera (medroxyprogesterone acetate), the law provides a path for you to seek accountability. We offer a free consultation and we operate on a contingency fee—which means we don’t get paid unless we win your case. You can reach our emergency hotline 24/7 at 1-888-ATTY-911.
Why Pfizer and Pharmacia & Upjohn Face Thousands of Lawsuits
As of June 2026, there are 3,769 active lawsuits consolidated in federal court against Pfizer, its subsidiary Pharmacia & Upjohn, and various authorized generic manufacturers. These cases are not about the drug’s effectiveness at preventing pregnancy; they are about a failure to warn.
The core of our argument is that these companies knew, or should have known, for years that synthetic progesterone can contribute to the development of intracranial meningiomas. While regulators in Europe and Canada issued direct warnings about this link as early as 2024, the U.S. label was not updated until December 2025. For many women, those months or years of missing information were the difference between a healthy life and a life-altering surgery.
We are pursuing these claims under several legal theories:
* Failure to Warn: The manufacturers had a duty to provide adequate warnings to patients and their doctors about the risk of brain tumors associated with long-term use.
* Strict Product Liability: The drug was unreasonably dangerous as it was designed and marketed without these essential neurological warnings.
* Negligent Pharmacovigilance: The companies failed to properly analyze adverse event reports and clinical studies, such as the 2024 French study that showed a 5.6-fold increase in meningioma risk for users exceeding one year of treatment.
Understanding MDL 3140: How the Federal Courts Handle Depo-Provera Claims
Because there are thousands of women across the country suffering from similar injuries caused by the same drug, the federal court system has consolidated these cases into a Multidistrict Litigation, known as MDL 3140.
An MDL is not a class action. In a class action, everyone’s case is merged into one. In an MDL, your case remains your own. The court centralizes the “discovery” phase—where we demand internal emails, testing data, and corporate memos from Pfizer—to make the process faster and more efficient.
We represent mass tort litigation clients by working through the complex federal system while maintaining the individual attention your specific injury requires. While the MDL handles the groundwork in a single federal district court, the law that governs your actual damages is often the law of the state where you received the injections.
The Science of Silence: When the Company Knew and Why the FDA Lagged
The scientific evidence linking medroxyprogesterone acetate to brain tumors has become impossible to ignore. A landmark 2024 study published in the BMJ found that women using the Depo-Provera shot for more than a year faced a significantly increased risk of developing a meningioma. A follow-up American study in the journal Cancers confirmed this, showing a 53% increase in odds that escalated the longer the drug was used.
The legal question we are asking is: why did Pfizer wait until the end of 2025 to update the American label?
“The FDA’s December 2025 label update serves as the ‘gold standard’ evidence that the previous labels were inadequate. The contrast with the 2024 European Medicines Agency (EMA) and Canadian regulatory actions provides a timeline of ‘actual knowledge’ for the defendants.”
Under federal regulation 21 CFR § 201.57, drug companies are required to update labels as soon as there is reasonable evidence of an association of a serious hazard with a drug. Furthermore, the “Changes Being Effected” (CBE) regulation allows a manufacturer to strengthen its warnings even before receiving formal FDA approval. Pfizer had the data, they had the legal mechanism to warn you, and they chose to wait.
Proving a Meningioma Claim: The Evidence that Decides Your Case
Winning a failure to warn lawsuit requires a mountain of medical and corporate evidence. We don’t just claim the drug caused the tumor; we prove it. The most central pieces of proof in your case will include:
- Prescribing Records and Pharmacy Logs: These establish your “duration of use.” Because the risk increases 5.6x after one year of use, proving how many years you were on the shot is the primary driver of your claim’s value. We move quickly because retail pharmacies often purge these records after 7 to 10 years.
- Pathology Samples and Imaging (DICOM): We work with experts to examine the tumor tissue. We are looking for “progesterone-receptor-positive” meningiomas. When a tumor has these receptors, it is like a lock that only the synthetic progesterone in Depo can open. This creates a biological “fingerprint” linking the tumor directly to the drug.
- Internal Corporate Communications: We seek the “smoking gun” emails that prove what Pfizer executives knew about the French study in early 2024 and why they decided to delay the U.S. warning.
The Insurance-Defense Playbook: How Manufacturers Protect Their Profits
You need to know what the other side is doing right now. Pfizer and their insurance-defense teams have been preparing for this litigation for years. Having an attorney like Lupe Peña on your side—a former insurance-defense lawyer who sat in those very rooms—is a central advantage. He knows their tactics because he was trained to use them.
Expect the manufacturer to use these three “plays” to devalue your claim:
* The “Learned Intermediary” Defense: They will argue that they did warn your doctor, and if your doctor didn’t warn you, it’s your doctor’s fault. Our counter is that the warning they gave to doctors was also late, weak, and insufficient.
* The “Alternative Cause” Argument: They will look through your entire medical history for any other reason you might have developed a tumor—genetics, dental X-rays, or environmental factors. We use neuro-oncologists to rebut these claims by pointing to the specific receptor-positive nature of your tumor.
* The “Watch and Wait” Lowball: If your tumor is currently small and your doctors are monitoring it rather than operating, the insurance company will argue you aren’t “injured enough” for a high settlement. We fight this by highlighting the psychological trauma and the permanent cost of lifelong MRI monitoring.
The 2026 Settlement Framework: Tiers of Compensation
In early 2026, both sides tentatively agreed to a settlement framework to resolve thousands of these cases. While details are being finalized, compensation is expected to be stratified into “points-based” tiers.
Cases involving invasive neurosurgery (craniotomies), permanent neurological disability, or death sit at the highest end of the value range, which can exceed $2,500,000. Mid-tier cases involve tumors that were treated with radiation or caused permanent symptoms like vision or hearing loss. The lower-tier cases, which still carry significant value starting around $150,000, are for women whose tumors require ongoing monitoring but have not yet required surgery.
We work until the evidence is frozen to ensure our clients are placed in the highest possible tier their medical record supports. Past results depend on the facts of each case and do not guarantee future outcomes, but we fight for the maximum measure of your losses, including:
* Past and future medical bills for surgeries, radiation, and MRIs.
* Loss of earning capacity if you can no longer work due to cognitive deficits.
* Permanent hearing or vision impairment.
* Seizures and the cost of anti-seizure medications.
* Pain, suffering, and the terror of a brain tumor diagnosis.
The Clock is Ticking: The Statute of Limitations
The most important thing you can do today is check your deadline. While every state is different, the “Discovery Rule” is the central issue here. This rule says the clock to file a lawsuit starts when you knew or should have known that the drug caused your injury.
For most women, the “trigger date” is December 2025—the moment the FDA finally forced the company to put the warning on the label. This means for many, the window to file a claim is closing fast. Waiting to see if your tumor grows could mean losing your right to sue entirely.

Frequently Asked Questions
Does Depo-Provera actually cause brain tumors?
Scientific studies, including a 2024 study in the BMJ and a 2024 study in Cancers, have shown a strong association between long-term medroxyprogesterone acetate use and an increased risk of meningioma. Specifically, users of the shot for more than one year showed a 5.6-fold increase in risk. While the litigation focuses on the failure to warn, the biological link is established through progesterone receptors found in these specific tumors.
I haven’t had surgery yet. Can I still file a lawsuit?
Yes. Even if your doctors have recommended a “watch and wait” approach with regular MRIs, you have a real injury. The cost of lifelong monitoring, the psychological distress of having a brain tumor, and the potential for future growth are all compensable damages. Under the 2026 settlement framework, even non-surgical cases are eligible for compensation.
What are the symptoms of a Depo-related meningioma?
Many women deal with fatigue and headaches for years without realizing they are signs of a tumor. Other serious symptoms include:
* Vision problems or sudden vision loss.
* Hearing loss or ringing in the ears (tinnitus).
* New-onset seizures or convulsions.
* Memory loss and confusion.
* Weakness in the arms or legs.
* Numbness or tingling in the face.
Is the Depo-Provera shot still on the market?
Yes. Despite the FDA label update in December 2025 and thousands of lawsuits, the drug has not been recalled. It is still available for use in the U.S. This makes it even more central for women to be aware of the risks and to discuss alternatives with their healthcare providers.
How do I know if my tumor is “progesterone-receptor-positive”?
This is determined through a pathological examination of the tumor tissue, usually after it has been surgically removed. If you have not had surgery, we can still move forward with your claim based on your usage history and clinical diagnosis. If you have had surgery, we work to preserve the tissue blocks from the hospital so they can be tested by our experts.
What if I was on a generic version of the shot?
You may still have a case. The MDL 3140 consolidation includes cases against authorized generic manufacturers. Because generic makers are required to use the same labeling as the brand-name drug (Pfizer), their failure to warn mirrors the parent company’s failure.
How long does a Depo-Provera lawsuit take?
Mass torts are a marathon, not a sprint. However, because MDL 3140 is already established and a tentative settlement framework was agreed upon in 2026, the process for new claimants may be more streamlined than in the early years of the litigation. During our free consultation, we can give you a better idea of the current timeline.
How much does it cost to hire Attorney911?
It costs you nothing upfront. We work on a contingency fee basis: 33.33% if the case is settled before trial, and 40% if it goes to trial. We pay for the experts, the filing fees, and the records requests. We only get paid if we successfully recover money for you.
