What is the most important information I should know about allopurinol (Zyloprim)?

Do not use this medication if you have ever had a serious allergic reaction to allopurinol. Stop taking the medicine and call your doctor at once if you have any signs of skin rash, no matter how mild.

Take each dose with a full glass of water. To reduce your risk of kidney stones forming, drink 8 to 10 full glasses of fluid every day, unless your doctor tells you otherwise.

Allopurinol can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often. Visit your doctor regularly.

Avoid drinking alcohol. It can make your condition worse.

Allopurinol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
