Proton Pump Inhibitors Lawsuit

Active Case

Available by prescription and over-the-counter, proton pump inhibitors (PPIs) are a particularly strong class of medication used to treat gastroesophageal reflux disease (GERD), frequent heartburn, ulcers, esophagitis and other conditions arising from an over-production of stomach acid. However, PPIs have been linked to serious injuries including acute interstitial nephritis, chronic kidney disease, kidney failure and other serious, debilitating effects which may result in hospitalization or, tragically, even death.

Hundreds of lawsuits have been filed in the U.S. against PPI manufacturers, alleging effects caused by the drugs. Many plaintiffs claim that manufacturers continue to promote the use of the drugs without proper warning, and that had they known they risks they would not have taken PPIs.

Proton Pump Inhibitors Side Effects

In December 2014, the FDA required that warning labels be included on prescription PPIs to explain the risk of developing acute interstitial nephritis, a dangerous swelling of the kidneys that could lead to damage, “at any point during PPI therapy.” Additionally, a study of more than 250,000 patients published in January 2016 in the Journal of the American Medical Association (JAMA)  found that those taking PPIs were 20 percent to 50 percent more likely to develop chronic kidney disease compared to those who were not on these medications.

Signs of kidney disease and failure may include:

  • Too much or not enough urine leaving the body
  • Swelling in legs, feet ankles and around the eyes
  • Fatigue or tiredness
  • Shortness of breath
  • Muscle cramps
  • Nausea and vomiting
  • Seizures or coma in severe cases
  • Back or abdominal pain or pressure
  • Nosebleeds
  • Skin rash
  • Death
