This medication is used to prevent gout and gouty arthritis. It will not treat a sudden/severe attack of gout and may make it worse. Gout occurs when your uric acid level gets too high, forming uric acid crystals in the joints that cause pain. Sulfinpyrazone belongs to a class of drugs known as uricosurics. It helps the kidneys to get rid of uric acid, thereby lowering high levels of uric acid and preventing crystals from forming. Lowering uric acid levels may also help your kidneys.
Take this medication by mouth, usually twice daily or as directed by your doctor. Take it with food, milk, or antacids to reduce stomach upset. To prevent kidney stones, it is best to drink a full glass of water (8 ounces or 240 milliliters) with each dose and at least another 8 glasses a day while taking this drug. If your doctor has directed you to restrict your fluid intake, consult your doctor for further instructions. Your doctor may also instruct you on how to decrease acidity in your urine (e.g., avoid large amounts of ascorbic acid/vitamin C) to prevent kidney stones. Your doctor may direct you to take other medications (e.g., sodium bicarbonate, citrate) to make your urine less acidic.
Dosage is based on your condition and response to treatment. Your doctor may direct you to take a low dose at first, then adjust your dose based on uric acid levels and your gout symptoms. After you have been symptom-free for several months and your uric acid levels are normal, your doctor may lower your dose to the lowest effective dose. Follow your doctor's directions carefully.
Sulfinpyrazone should not be started during a sudden/severe gout attack. Wait until your current attack is over before starting this medication. You may experience an increase in the number of gout attacks for several months after starting this medicine while the body removes extra uric acid. If you have a gout attack while taking sulfinpyrazone, continue taking it along with your medications for gout pain.
Sulfinpyrazone is not a pain reliever. To relieve pain from gout, continue to take your medicines prescribed for pain from gout attacks (e.g., colchicine, ibuprofen, indomethacin) as directed by your doctor.
