Talk with your doctor about the best treatment plan for you. You treatment will depend on the cause of your acute interstitial nephritis. Treatment options include the following:

If medications are the cause of your interstitial nephritis, your doctor may have you stop taking medications or prescribe a different one.

Antibiotics used to treat an infection and a corticosteroid or cyclophosphamide medicine may also be used to treat interstitial nephritis. Usually, a kidney biopsy is done to confirm the diagnosis before starting a corticosteroid or cyclophosphamide.

Some people with interstitial nephritis need dialysis. During dialysis, a machine does the work of your kidneys by removing waste.

Prevention

To help reduce your chances of developing acute interstitial nephritis, your doctor may suggest you avoid certain medications such as penicillin or nonsteroidal anti-inflammatory drugs.
