Common Uses

Zyloprim is a drug used primarily to treat conditions arising from excess uric acid, most notably chronic gout. It is used in the treatment of many symptoms of gout, including acute attacks, tophi (collection of uric acid crystals in the tissues, especially around joints), joint destruction, and uric acid stones. Gout is a form of arthritis characterized by increased blood levels of uric acid. Zyloprim works by reducing uric acid production in the body, thus preventing crystals from forming.

How to Take

Use Zyloprim as directed by your doctor. Check the label on the medicine for exact dosing instructions. Take Zyloprim by mouth after meals to decrease stomach upset. Drinking extra fluids while you are taking Zyloprim is recommended. Check with your doctor for instructions. Continue to take Zyloprim even if you feel well. Do not miss any doses.

Zyloprim may cause drowsiness. This effect may be worse if you take it with alcohol or certain medicines. Use Zyloprim with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

You may experience an increase in gout attacks for several months after you begin taking Zyloprim. Your doctor may give you another medicine (colchicine) to help decrease these gout attacks. Contact your doctor if you experience frequent or severe gout attacks.
