Allopurinol contains the active ingredient allopurinol, a xanthine oxidase inhibitor. It primarily treats and prevents kidney stones and gout by lowering excess uric acid levels in the bloodstream. Allopurinol can also be used to prevent high uric acid levels in individuals receiving chemotherapy medications.

Allopurinol is available in tablet form (Zyloprim) with strengths of 10 mg and 300 mg and as a solution for intravenous injection with a strength of 20 mg/ml. The recommended dosage of Allopurinol varies depending on the patient’s condition and age. For gout, adults typically start with 100 to 300 mg per day, with a maximum of 800 mg per day. A doctor determines children’s dosage. Allopurinol works by inhibiting xanthine oxidase, an enzyme involved in uric acid production, thus reducing uric acid levels in the body.

Common side effects of Allopurinol include abnormal liver function tests, diarrhea, drowsiness, increased gout attacks during initial doses, kidney problems, nausea, rashes, and vomiting. Adverse side effects can include severe allergic reactions, liver problems, signs of infection, and blood vessel inflammation. It is crucial to follow the instructions given by your physician, undergo regular medical tests, and report any unusual symptoms. Store Allopurinol in its original container at room temperature, away from light, heat, and moisture. Avoid consuming alcohol while taking Allopurinol. Always consult your healthcare provider or physician for medical advice about side effects and proper usage.
