Proton Pump Inhibitors (PPI)

Nexium · Prilosec · Prevacid — kidney disease and long-term use injuries

Active MDLIn re: Proton-Pump Inhibitor Products Liability Litigation (No. II), MDL No. 2789 (D.N.J., Hon. Claire C. Cecchi).

Proton pump inhibitors (PPIs) — including Nexium (esomeprazole), Prilosec (omeprazole), Prevacid (lansoprazole), Protonix (pantoprazole), and Dexilant (dexlansoprazole) — are widely used to treat heartburn and GERD. Long-term use has been associated with chronic kidney disease, acute interstitial nephritis, acute kidney injury, and end-stage renal disease. Federal cases are consolidated in New Jersey.

Background

What this litigation is about.

PPIs are among the most-prescribed drug classes in the United States, available both by prescription and (in lower doses) over the counter. They work by blocking gastric acid production.

Beginning in the mid-2010s, epidemiologic studies (JAMA Internal Medicine, JASN, BMJ Open, and others) reported associations between long-term PPI use and chronic kidney disease, acute interstitial nephritis, and end-stage renal disease. The FDA has issued label warnings addressing acute interstitial nephritis (2014) and other risks.

The JPML consolidated federal PPI kidney-injury cases in the District of New Jersey as MDL 2789 in August 2017, before Judge Claire Cecchi. Bellwether case selection and expert discovery are ongoing across manufacturers including AstraZeneca (Nexium, Prilosec), Takeda (Prevacid, Dexilant), Pfizer/Wyeth (Protonix), and others.

Reported injuries

Complications documented in this litigation.

Chronic kidney disease (CKD)

Progressive loss of kidney function documented after long-term PPI use.

Acute interstitial nephritis (AIN)

Inflammation of the kidney's interstitial tissue — the injury the FDA has warned about since 2014.

Acute kidney injury (AKI)

Sudden loss of kidney function requiring hospitalization or dialysis.

End-stage renal disease (ESRD)

Kidney failure requiring long-term dialysis or transplant.

Bone fractures

Increased fracture risk associated with long-term high-dose PPI use.

Who may qualify

An honest self-check.

  • You took a PPI (Nexium, Prilosec, Prevacid, Protonix, Dexilant, or a generic) — often for months or years.

  • You were later diagnosed with chronic kidney disease, acute interstitial nephritis, acute kidney injury, or end-stage renal disease.

  • You have pharmacy records and nephrology records documenting the use and the diagnosis.

  • The kidney injury was not otherwise explained by unrelated causes.
