Aciphex is an anti-heartburn medication that contains rabeprazole. It works by decreasing the amount of acid in the stomach.
Aciphex and Nephritis
Evidence linking Aciphex and nephritis has been growing for over a decade. The first case report was published in 2005 in the journal Nephrology. In another report, an 84 year-old woman rapidly developed kidney failure after taking Aciphex.
FDA Updates Warning Label
In December 2014, the FDA updated the label on Aciphex with new warnings about acute interstitial nephritis. The FDA also contraindicated Aciphex in patients with hypersensitivity reactions.
Studies Link PPIs and Nephritis
In April 2015, a study published in CMAJ Open associated the use of Proton Pump Inhibitors (PPIs) with a tripled increased risk of nephritis. The researchers analyzed data on 290,000 adults over 66 years old in Ontario, Canada.
What is Nephritis?
Nephritis means “kidney inflammation,” and acute interstitial nephritis is a sudden inflammation of the interstitial tissue. It causes swelling in the spaces between tubules, which help the kidneys clean the blood. It is also sometimes called “tubulo-interstitial nephritis.”
What Causes Nephritis?
Nephritis has many causes, but the most common is an allergic reaction to medications in the bloodstream. Patients will need to stop taking Aciphex and any other medication that might be causing kidney problems. Over 100 medications are known to cause nephritis, but the most common culprits are Proton Pump Inhibitors (PPIs).
Symptoms of Interstitial Nephritis
- Blood in the urine
- Decreased or increased urine output
- Nausea, vomiting
- Loss of appetite
- Fluid retention
- Swelling in the body
How is Interstitial Nephritis Treated?
Most patients with interstitial nephritis will need to be hospitalized, where they will typically receive anti-inflammatory medications (corticosteroids). About 50% of patients with nephritis develop symptoms of kidney failure.
When kidney function drops below 15% of normal, patients will need dialysis to mechanically clean the blood. The kidneys can recover from moderate damage, but the longer nephritis goes untreated, the higher the risk of kidney failure.
