Eglet and Dimopoulos Law Firms File Groundbreaking Lawsuit Against Pfizer, Alleging Birth Control Shot Depo-Provera Causes Brain Tumors

Listen to this blog post:

A landmark lawsuit was filed today by Eglet Law Group and the Dimopoulos Law Firm in Nevada’s District Court against Pfizer and several generic pharmaceutical manufacturers, including Viatris, Greenstone, Prasco, and Pharmacia & Upjohn Co., on behalf of a woman who claims to have developed multiple brain tumors directly linked to the use of Depo-Provera, a widely prescribed contraceptive injection.

The lawsuit contends that these companies neglected to adequately warn consumers of known risks associated with the drug, which is marketed under the name “Depo Shot.”

According to the complaint, Depo-Provera caused the plaintiff to suffer “serious and potentially debilitating intracranial meningiomas” after years of regular use.

The plaintiff alleges that despite mounting evidence, the companies failed to include warnings on U.S. labels about this risk, even as labels in Canada and the European Union began to do so.

The complaint asserts that the defendants knew or should have known of the “highly increased risk of brain tumors,” based on “decades of scientific literature” that documented a correlation between high-dose progestin contraceptives and brain tumor development.

“Women trust pharmaceutical companies to prioritize their health, and if that trust is broken, we are here to help them seek justice,” said attorney Robert Eglet.

“We are committed to holding these companies accountable for the safety of their products,” said attorney Steve Dimopoulos.

The complaint highlights research published in the British Medical Journal earlier this year that found a 555% increased risk of intracranial meningiomas in patients who used Depo-Provera long-term, a finding cited as further evidence that the defendants failed to adequately inform consumers and the medical community in the U.S.

The suit also claims that in July 2024, U.S. labels for Depo-Provera were updated but still did not include a warning about meningiomas, despite the overwhelming body of research.
