October 2025 Update — Truvada & TDF Drug Lawsuits
As of October 2025, the Truvada and TDF drug lawsuits continue to advance in both federal and state courts across the country. These cases target Gilead Sciences, the manufacturer of Truvada, Viread, Atripla, Complera, and Stribild, alleging that the company’s tenofovir disoproxil fumarate (TDF) drugs caused serious kidney damage, renal failure, and bone density loss—and that Gilead intentionally withheld a safer alternative formulation.
Key developments include:
- The TDF Products Liability Litigation (MDL No. 2881) in the Northern District of California remains active, with more than 26,000 pending cases as of fall 2025.
- Plaintiffs claim Gilead knew as early as the early 2000s that its TDF-based HIV and PrEP drugs were highly toxic to the kidneys and bones, but delayed developing or releasing a safer version—tenofovir alafenamide fumarate (TAF)—to maximize profits before patent expiration.
- In 2025, the court ruled that failure-to-warn and design defect claims could proceed, rejecting Gilead’s arguments that federal preemption shielded it from liability.
- Several bellwether cases are now in discovery, with the first trials expected in mid-2026. These outcomes will help establish the strength of evidence potentially linking TDF toxicity to long-term organ damage.
- Gilead continues to deny all allegations, asserting that the FDA-approved labeling adequately warned of potential risks and that its TDF medications remain safe and effective when used as prescribed.
- Settlement negotiations have been intermittent, but no global resolution has been announced. Legal experts expect renewed discussions following the first bellwether verdicts.
As of October 2025, the Truvada and TDF drug lawsuits remain in the active discovery phase. The coming year will be pivotal as key expert testimony is tested, trial dates are finalized, and the court determines whether Gilead may face broad liability for alleged long-term kidney and bone injuries associated with its HIV and PrEP medications.
Individuals who have experienced kidney or bone-related health issues after using Truvada or other TDF-based medications are encouraged to consult with a legal professional to understand their rights and potential avenues for compensation.

What is Truvada and Truvada PrEP?
Truvada is a medicine used to treat and even prevent HIV. Truvada is manufactured by Gilead Sciences Inc. and is approved to both treat people who have tested positive for HIV, and protect HIV-negative adults from contracting the virus.
When used as protection instead of treatment, the medicine is called Truvada for pre-exposure prophylaxis, or Truvada for PrEP.
Truvada is made of emtricitabine and tenofovir disoproxil fumarate. When used to treat HIV-positive individuals, it is used in combination with other medicines such as nucleoside reverse transcriptase inhibitors (NRTIs).
While there is no cure for HIV or AIDS, Truvada has been approved as an effective treatment and, in the case of individuals who have not contracted HIV, a preventative measure (marketed as Truvada for PrEP).
