What is allopurinol (Zyloprim)? Allopurinol reduces the production of uric acid in your body. Uric acid buildup can lead to gout or kidney stones. Allopurinol is used to treat gout or kidney stones, and to decrease levels of uric acid in people who are receiving cancer treatment. Allopurinol may also be used for purposes not listed in this medication guide.
1 Advise your doctor if you have kidney problems. Allopurinol can be still used, but the dose may need to be adjusted. 2  Common side effects include stomach pain, headache, diarrhea, and rash.  Discontinue allopurinol if you develop a rash or a fever, and call your doctor.
