Proton-Pump Inhibitor (PPI) Kidney Damage Claims

Proton-pump inhibitors—commonly known as PPIs—are among the most widely prescribed and over-the-counter medications in the world. Brands like Prilosec, Nexium, Prevacid, Protonix, and Dexilant have been used by tens of millions of Americans to treat heartburn, acid reflux, and gastroesophageal reflux disease. Many people took these drugs daily for months or years, often without being told that long-term use could quietly destroy their kidneys.

How PPIs Can Damage the Kidneys

PPIs work by reducing the amount of acid produced in the stomach. While they are effective at managing symptoms of acid reflux, long-term use has been linked to a cascade of kidney problems. The most common pathway begins with acute interstitial nephritis, an inflammatory condition of the kidneys that can develop without obvious symptoms. If undetected, this inflammation can progress to chronic kidney disease—a condition in which the kidneys gradually lose their ability to filter waste from the blood. In the most severe cases, chronic kidney disease advances to end-stage renal disease, requiring dialysis or a kidney transplant.

Studies have found that long-term PPI users face up to a 50 percent increased risk of developing chronic kidney disease compared to non-users. The risk grows with duration of use, and many patients were prescribed or self-medicated with PPIs for far longer than originally intended.

Who May Be Eligible

Individuals who took PPI medications for extended periods and were subsequently diagnosed with kidney inflammation, chronic kidney disease, or end-stage renal disease may be eligible to pursue compensation. This includes patients who were prescribed PPIs by their doctors as well as those who purchased over-the-counter versions for self-treatment of heartburn and acid reflux.

Litigation and Settlements

The PPI litigation has been one of the larger mass tort proceedings in recent years, with more than 18,000 lawsuits filed against manufacturers including AstraZeneca, GlaxoSmithKline, Procter & Gamble, Pfizer, and Takeda. A total settlement of approximately $590 million has been reached, with AstraZeneca contributing the largest share at $425 million. The litigation is substantially resolved, but some claims remain active.

Compensation Available

PPI injury claimants may be entitled to compensation for kidney disease treatment costs, dialysis expenses, kidney transplant costs, medical monitoring and specialist care, lost wages and reduced earning capacity, pain and suffering, and diminished quality of life. Each case is evaluated based on the severity of the kidney injury and its impact on the individual’s health and daily life.

If you took Prilosec, Nexium, Prevacid, or another PPI medication long-term and were diagnosed with kidney disease, you may have the right to seek compensation.
