Our lawyers are reviewing potential lawsuits for people who developed acute interstitial nephritis (AIN) after taking Aciphex (generic: rabeprazole), a proton pump inhibitor (PPI) heartburn medication. AIN occurs when the kidneys are unable to filter wastes and fluid properly because of inflammation.

What’s the Problem?
Acute interstitial nephritis is a rare but important cause of kidney failure (end stage renal disease or ESRD), and proton pump inhibitors are thought to be a leading cause of the condition. The first case  of AIN specifically linked to rabeprazole (the active ingredient in Aciphex) in the U.S. was reported in 2005. At least 4 cases  have been linked to the drug in Canada, as well as one in France  in which an 84-year-old woman underwent a renal biopsy because of rapidly progressive renal failure. Rabeprazole-induced AIN was diagnosed, and the study’s authors cautioned that the condition may complicate the course of any proton pump inhibitor treatment. Clinician's awareness of nephritis is essential for early diagnosis and prompt recovery, according to the researchers.
FDA Warning on Aciphex
In December 2014, the U.S. Food & Drug Administration (FDA) updated Aciphex labels  to include a warning about acute interstitial nephritis. The agency said that nephritis is a hypersensitivity reaction that can occur at any time during treatment with Aciphex.
What is AIN?
Acute interstitial nephritis is characterized by the presence of an inflammatory cell infiltrate in the interstitium of the kidney. Untreated AIN can lead to kidney failure, and it is estimated that up to 15% of hospitalizations for acute renal failure may be due to the condition.
- Blood in the urine
- Increased or decreased urine output
- Mental status changes (drowsiness, confusion, coma)
- Swelling of the body
- Weight gain
The mainstay of treatment for acute interstitial nephritis is supportive therapy. After a diagnosis of AIN has been confirmed, potentially offending medications should be discontinued and underlying infections treated. If Aciphex is determined to be the likely cause of your nephritis, you may want to consider discontinuing treatment in favor of a heartburn drug with less severe side effects. However, you should never quit taking a medication without consulting your physician first.
