Allopurinol 100mg

Allopurinol 100mg — Uses and Benefits

Allopurinol is mainly used to control high uric acid levels in the blood, which can cause gout and kidney stones.

WHAT THIS MEDICINE IS USED FOR

• Long-term prevention of gout attacks
• Treatment of high uric acid levels (hyperuricemia)
• Preventing uric acid build-up during chemotherapy or radiotherapy
• Managing recurrent uric acid kidney stones

HOW IT WORKS

• It blocks an enzyme called xanthine oxidase
• This enzyme is needed to make uric acid in the body
• By blocking it, allopurinol lowers uric acid levels over time
• Lower uric acid reduces the chance of gout attacks and stone formation

WHAT IT IS NOT USED FOR

• It does not relieve pain during a sudden, acute gout attack
• It is not a painkiller or anti-inflammatory medicine
• It should not be started during an active gout flare
• It is not used for general joint pain unrelated to uric acid
