The Depo-Provera lawsuit side effects have gained attention as women who used the injectable birth control report serious health issues, including meningioma brain tumors and bone density loss. As of September 2025, more than 800 lawsuits are consolidated in a federal multidistrict litigation (MDL) overseen by Judge Casey Rodgers in Florida, alleging Pfizer failed to adequately warn about these risks despite evidence dating back years.

Depo-Provera, an injectable contraceptive containing medroxyprogesterone acetate, is administered every three months to prevent pregnancy by suppressing ovulation. While effective for many, prolonged use has been associated with significant health concerns. These Depo-Provera lawsuit side effects form the basis of ongoing litigation, with plaintiffs claiming inadequate labeling from Pfizer.
Common long-term side effects linked to Depo-Provera include:
Women using Depo-Provera for over a year face heightened risks, particularly for meningiomas, prompting calls for stronger warnings similar to those issued in Canada since 2016.
Meningiomas, tumors on the brain or spinal cord's protective layers, are a primary focus in Depo-Provera lawsuits. A March 2024 BMJ study showed women using the shot for more than one year had over five times the risk of developing these tumors compared to non-users. Though often non-cancerous, meningiomas can cause severe symptoms such as:
Treatment may involve surgery, radiation, or monitoring, with recovery varying by tumor size and location. Pfizer's U.S. label omits this risk, unlike international versions, fueling claims of negligence.
Depo-Provera's progestin suppresses estrogen, crucial for bone health, leading to significant density loss up to 5-7% in the first two years. This increases fracture risk and osteoporosis, especially in younger users whose bones are still forming. Factors like low calcium or vitamin D intake exacerbate the issue.
Past litigation, including a class action, resulted in over $2 million in settlements for failure to warn about this risk. Supplementation and monitoring are recommended, but long-term damage can persist post-discontinuation.
Hormonal fluctuations from Depo-Provera often trigger headaches, from tension types to intense migraines that disrupt daily life. These may stem from vascular changes or, in rare cases, signal an underlying meningioma. Persistent headaches warrant immediate medical evaluation, as they could indicate tumor growth.
Many users report mood swings, heightened anxiety, or depression, potentially due to progestin's effects on brain chemistry. Untreated, these can strain relationships and productivity. Meningiomas may worsen symptoms by affecting emotional regulation areas, highlighting the need for prompt intervention.
Seizures are a reported Depo-Provera lawsuit side effect, particularly in those with seizure histories, as the hormone may alter brain electrical activity. Symptoms like sudden convulsions or loss of awareness require urgent care and could tie to tumor development.
Untreated issues can escalate:
Early detection through screenings can mitigate harm, but many learned of risks too late due to labeling gaps.

Meningioma tumors (5x risk after one year) and bone density loss leading to osteoporosis top the list, alongside seizures and mood disorders.
Yes, prolonged use elevates meningioma risk, as confirmed by 2024 research; lawsuits claim Pfizer underreported this.
Over 800 cases form an MDL as of September 2025, not a traditional class action, allowing individual compensation pursuits.
Women using the shot for 1+ year with meningioma diagnosis or severe bone loss; family for wrongful death.
Pfizer advises no more than two years unless necessary, due to escalating risks like tumors and bone issues.
Yes, for bone loss; meningioma warnings appear in Canada but not U.S. labels, central to lawsuits.
Weight gain affects many via metabolism shifts; clots risk is nearly four times higher, per National Library of Medicine data.
Studies suggest yes, especially with multi-year use, due to progestin's tumor-promoting effects.
