Zyloprim (Allopurinol)

Zyloprim (allopurinol) is a medication that helps prevent attacks of gout.

Zyloprim reduces the body's production of uric acid by inhibiting an enzyme called xanthine oxidase. This enzyme is involved in the chemical process that produces uric acid in the body. Buildups of excess uric acid can lead to gout and kidney stones.

Zyloprim belongs to a class of medications called xanthine oxidase inhibitors.

Taking Zyloprim

Zyloprim is available in 100 and 300 mg oral tablets. The usual dose for Zyloprim is between 50 to 800 mg every day, depending on a doctor's prescription.

It takes time for this medicine to work, and patients may have flares of gout when they start. It is important for people starting Zyloprim to be patient and continue taking the medication as prescribed by their doctor.

If gout flares while taking Zyloprim, patients should see their doctor so that the flare can be treated with a different medicine.
