Pronunciation

Generic Name: allopurinol (AL-oh-PURE-i-nol)
Brand Name: Zyloprim

Zyloprim is used for:

Treating gout. It is used to treat high uric acid levels in the blood or urine caused by certain types of cancer chemotherapy. It is also used to treat certain patients with a certain type of kidney stones and high amounts of uric acid in the urine. It may also be used for other conditions as determined by your doctor.

Do NOT use Zyloprim if:

  • you are allergic to any ingredient in Zyloprim
  • you do not have symptoms caused by high blood uric acid levels
  • you are taking didanosine or pegloticase

Contact your doctor or health care provider right away if any of these apply to you.
