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

You should not use this medicine 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.

What is allopurinol?

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.

How should I take allopurinol?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

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.

Take with food if allopurinol upsets your stomach.

You may have gout attacks more often when you first start taking allopurinol. Your doctor may recommend other gout medication to take with allopurinol. Keep using your medication as directed and tell your doctor if your symptoms do not improve after 6 weeks of treatment.

You may need to follow a special diet while using allopurinol. Follow all instructions of your doctor or dietitian. Learn about the foods to eat or avoid to help control your condition.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.

Avoid drinking alcohol. It may worsen your condition.

Stop using allopurinol and call your doctor at once if you have:

any skin rash, no matter how mild;
flu symptoms, joint pain, easy bruising, unusual bleeding;
painful urination, blood in the urine;
little or no urination;
numbness, tingling, burning pain;
worsening gout symptoms; or
liver problems --loss of appetite, weight loss, stomach pain (upper right side), itching, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
