Zyloprim

Generic name: Allopurinol

Why is Zyloprim prescribed?

Zyloprim 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.

Zyloprim is also used to manage the increased uric acid levels in the blood of people with certain cancers, such as leukemia. It is also prescribed to manage some types of kidney stones.

Most important fact about Zyloprim

Zyloprim will not stop a gout attack that is already underway. However, when taken over a period of several months, this drug will begin to reduce your symptoms. It's important to keep taking it regularly, even if it seems to have no immediate effect.

How should you take Zyloprim?

Take Zyloprim exactly as prescribed. Your doctor will probably start you on a low dosage, increasing it gradually each week until you reach the dosage that is best for you.

A typical starting dose is one 100-milligram tablet per day. You may want to take Zyloprim immediately after a meal to minimize the risk of stomach irritation.

You should avoid taking large doses of vitamin C because of the increased possibility of kidney stone formation.

While taking Zyloprim you should drink plenty of liquids—10 to 12 glasses (8 ounces each) per day—unless otherwise prescribed by your doctor.

To help prevent attacks of gout, you should also avoid beer, wine, and purine-rich foods such as anchovies, sardines, liver, kidneys, lentils, and sweetbreads.

If you have been taking colchicine and/or an anti-inflammatory drug, and others, to relieve your gout, your doctor will probably want you to continue taking this medication while your Zyloprim dosage is being adjusted. Later, when you have had no attacks of gout for several months, you may be able to stop taking these other medications.
