Sulfinpyrazone is used in the treatment of chronic gout (gouty arthritis), which is caused by too much uric acid in the blood. The medicine works by removing the extra uric acid from the body. Sulfinpyrazone does not cure gout, but after you have been taking it for a few months it may help prevent gout attacks. This medicine will help prevent gout attacks only as long as you continue to take it. Sulfinpyrazone is sometimes used to prevent or treat other medical problems that may occur if too much uric acid is present in the body.
Side effects of sulfinpyrazone are uncommon and usually mild. The most frequent adverse reactions involve stomach upset. Accordingly, combining the drug with food, milk or antacids is advised. Sulfinpyrazone, however, can cause kidney pain and uric acid kidney stones. Rarely, it has caused severe anemias.
