Allopurinol

What is Allopurinol used for?

Allopurinol is a medicine that helps lower uric acid levels in your blood. High uric acid can cause gout, which is painful swelling in your joints. It can also cause kidney stones. Doctors prescribe it for people with gout symptoms like joint pain, swelling, or kidney problems caused by high uric acid. It's also used for some people with cancer who have high uric acid. However, it's not used if you just have high uric acid without any symptoms.

How does Allopurinol work?

Allopurinol is a medicine that lowers uric acid in your body. It works by blocking an enzyme (xanthine oxidase) that makes uric acid. This means less uric acid is produced. A part of the medicine, oxypurinol, also helps lower uric acid. Your body absorbs most of the medicine when you take it, and your kidneys get rid of it.
