Why do I need this medicine?

Allopurinol is used to reduce the high level of uric acid in your body.

Build-up of uric acid in your body can cause gout, gouty arthritis, kidney or urinary tract stones. Allopurinol is used to prevent or treat these conditions.

This medicine is also used to treat high levels of uric acid that may occur in people with G6PD deficiency.

Allopurinol does not treat sudden gout attacks as it cannot relieve acute pain. Your doctor may give you extra medicines during the early part of Allopurinol therapy to help you cope with acute pain.
