Thousands of women in the U.S. are pursuing legal claims after using the injectable contraceptive Depo-Provera (the “Depo Shot”), alleging that long-term use led to brain tumors known as meningiomas—and that manufacturers failed to adequately warn of the risk. These claims, filed against Pfizer Inc. and other parties, center on allegations of defective design, failure to warn, and causation of serious injury. As of, 2025, more than 1,200 cases have been consolidated in a federal multidistrict litigation (MDL) in Florida; no nationwide settlement or class-wide verdict has yet been publicly disclosed.
This article dissects the legal, medical, and financial facets of the Depo shot litigation. It describes how these cases are handled, what proof is required, and the maximum compensation to which victims are entitled.
What Is the Depo Shot?
Depo-Provera is an injectable contraceptive that releases medroxyprogesterone acetate (MPA), a synthetic form of the hormone progesterone. Each injection prevents pregnancy for about three months and has been FDA-approved since the 1990s.
While effective as a contraceptive, long-term use has been linked in scientific literature to several side effects — including loss of bone density, mood changes, and, in recent research, an elevated risk of meningioma.
In 2023 and 2024, European health regulators and the U.S. FDA required updated product labeling to include warnings about possible brain-tumor risk with prolonged exposure.
Why Are Women Filing Depo Shot Lawsuits?
Women who filed Depo-Provera lawsuits claim they did not receive proper warning about the side effects. These cases target companies like Pfizer, Pharmacia & Upjohn, and related manufacturers. Plaintiffs argue that the drugmakers:
- Failed to warn doctors and patients of long-term risks
- Misrepresenting the drug’s safety in advertising
- Ignored or downplayed adverse event data
- Did not conduct enough safety research
The key argument is the lack of informed consent. Many users say they would have chosen another method without knowing the risks. Bone fractures, memory loss, autoimmune disease, and reproductive damage are among the most common injuries cited.
Common Side Effects Named in Depo Shot Lawsuits
Medical records show that Depo users have experienced a wide range of physical and emotional symptoms. These symptoms often worsened over time. Long-tail keyword research shows users frequently search for phrases like:
- “Depo shot bone loss lawsuit”
- “Can Depo-Provera cause permanent damage?”
- “Neurological side effects from Depo shot”
- “Depo-Provera infertility claim”
- “Autoimmune reaction after Depo injection”
Here are the most commonly reported conditions:
- Severe bone density loss or osteoporosis
- Cognitive decline or memory problems
- Chronic fatigue or autoimmune flare-ups
- Mood swings, anxiety, or depression
- Irregular or absent menstrual cycles
- Infertility or long-term reproductive harm
In extreme cases, women lose mobility due to spinal or hip fractures.
Who Qualifies to File a Depo Shot Lawsuit?
You may qualify to file a Depo shot lawsuit if:
- You received multiple Depo-Provera injections over an extended period (typically more than one year)
- You suffered from a medically diagnosed condition linked to Depo use (such as osteoporosis, cognitive decline, or autoimmune disease)
- You did not receive a full warning about the risks from your doctor or pharmacist
- Your injuries caused lasting damage or required ongoing treatment
Some states impose strict statutes of limitations. That means your window to file a claim could expire soon. Speak to a Depo-Provera injury lawyer immediately to find out if you are still eligible.
Evidence and Scientific Support
Several peer-reviewed studies have examined the link between progestin exposure and meningioma development. For example:
2022 French epidemiological study found a dose-dependent association between medroxyprogesterone acetate and meningioma incidence.
FDA safety communication (2023) acknowledged rare reports of brain tumors in long-term users and updated labeling requirements.
These findings do not prove causation for any individual case but support the scientific basis of the claims now under review in federal court.
Legal Strategy in Depo Shot Litigation
Most Depo shot lawsuits fall under product liability law. These cases argue that the product was defective in its warning label, design, or manufacturing. Your attorney may build a case based on the following claims:
- Failure to warn: The company did not inform patients of known risks properly.
- Negligence: The company ignored danger signs or failed to research long-term outcomes.
- Misrepresentation: The manufacturer advertised the shot as safe while hiding its risks.
Some law firms also file claims under medical malpractice if a doctor prescribed the drug despite clear contraindications.
How Much Can Victims Receive in Depo Shot Lawsuits?
The value of your claim depends on the extent of your injury. Some victims may receive compensation for:
- Medical bills (past and future)
- Lost income or earning potential
- Pain and suffering
- Emotional trauma
- Loss of fertility or quality of life
- Legal experts estimate settlements could range from $50,000 to over $500,000, depending on the damage and state laws. In rare cases, punitive damages may apply if the court finds the manufacturer acted recklessly.
How Long Do You Have to File?
Every state sets a time limit to file personal injury or product liability claims. This limit is called the statute of limitations. For Depo shot lawsuits, the time frame often starts when you first noticed the injury. In most states, you must file within 2 to 3 years of that date.
Some states allow exceptions if:
- The injury was not discovered until years later
- The victim was a minor when they received the injection

Recent Legal Trends and Case Updates
Legal momentum is building. In recent years, several women received compensation through settlements or individual verdicts. Although no mass tort or class action lawsuit currently exists, the volume of claims continues to grow. Law firms across the U.S. are actively recruiting Depo shot victims for individual cases.
According to court records, plaintiffs have targeted companies like:
- Pfizer Inc.
- Pharmacia & Upjohn Co.
- Wyeth Laboratories
Some of these companies have already faced similar litigation over hormone-based drugs in the past. This history strengthens current claims.
