Nationwide Case Review · 2026

Used Depo-Provera and Later Diagnosed With Intracranial Hypertension?
Cornerstone Law Can Help.

Plaintiffs survived a motion to dismiss in the lead federal case in December 2025, and failure-to-warn and negligent design claims are now proceeding into discovery. The JPML is expected to rule on MDL centralization in mid-2026. Cornerstone Law is reviewing cases nationwide — with no upfront cost to you.

Depo-Provera, the widely used injectable contraceptive manufactured by Pfizer, contains medroxyprogesterone acetate — a synthetic hormone linked to increased cerebrospinal fluid pressure. Plaintiffs allege Pfizer failed to warn about the risk of intracranial hypertension, ignored early safety signals, marketed the drug as safe for long-term use, and downplayed severe neurological side effects including vision loss, chronic migraines, and tinnitus.

Where the Litigation Stands Now

Multiple federal filings allege that long-term use of Depo-Provera caused intracranial hypertension (pseudotumor cerebri), vision loss, and severe neurological symptoms. Cases are most active in the Eastern District of Pennsylvania, Northern District of Georgia, and Southern District of Illinois, with a JPML petition for centralization pending.

Harris v. Pfizer Inc.

Case No. 2:25-cv-01477 — Eastern District of Pennsylvania

December 2025: plaintiffs survived a partial motion to dismiss. The court allowed claims for failure to warn, negligent design, and breach of implied warranty to proceed, and ordered Phase I discovery, including production of internal safety-signal analyses and adverse-event reports related to intracranial hypertension.

In re: Depo-Provera Intracranial Hypertension Litigation

Proposed MDL No. 3112 — requested venue: Eastern District of Pennsylvania

Status: plaintiffs have petitioned the JPML to centralize all federal Depo-Provera cases. The panel is expected to rule in mid-2026. Several cases are already consolidated for coordinated pretrial proceedings in anticipation of MDL formation.

Phase I discovery is already underway in the lead case. Internal safety-signal analyses and adverse-event reports are being produced — the same type of evidence that has proven decisive in prior pharmaceutical MDLs. Filing now helps position your claim ahead of MDL formation.

How Pfizer Is Alleged to Have Failed Depo-Provera Patients

Depo-Provera contains medroxyprogesterone acetate, which plaintiffs allege interferes with cerebrospinal fluid dynamics and can cause dangerous increases in intracranial pressure. Plaintiffs contend Pfizer had access to safety signals indicating this risk and failed to act on them.

Failure to Warn

Pfizer allegedly failed to include adequate warnings about the risk of intracranial hypertension in its labeling, leaving patients and prescribers uninformed about a serious neurological risk.

Ignored Safety Signals

Plaintiffs allege internal safety-signal analyses and adverse-event data showed a link between Depo-Provera and intracranial hypertension, and that Pfizer failed to respond appropriately.

Negligent Design

The drug's formulation and dosing allegedly created foreseeable risks of cerebrospinal fluid pressure increase that plaintiffs say could have been addressed through alternative design.

Misleading Long-Term Safety Claims

Depo-Provera was marketed as safe for long-term use, with neurological side effects allegedly downplayed or omitted from patient-facing materials.

What Clients Ask Us Most

I only used Depo-Provera for a short time — do I still qualify?

Possibly. While longer use is more commonly cited in these cases, both short-term and long-term users may have a claim depending on their specific diagnosis and symptom timeline.

What does it cost to work with Cornerstone Law?

We handle Depo-Provera cases on contingency — no upfront fee, and we only get paid if we recover compensation for you.

Is there a class action or MDL for Depo-Provera yet?

Not formally yet. A petition to centralize federal cases into an MDL is pending before the JPML, with a ruling expected in mid-2026. Several cases are already coordinating in anticipation of that outcome.

My symptoms went away after I stopped using it — can I still file?

Resolved symptoms don't necessarily rule out a claim, particularly if you incurred medical costs, missed work, or experienced lasting effects like vision changes. It's worth having your case reviewed.

Why Cornerstone Law: We track every development in the emerging MDL — from Phase I discovery to JPML rulings to bellwether scheduling — to ensure our clients are positioned for the strongest possible recovery.
