Medical Overview
Allopurinol is listed as Other containing Allopurinol. A medicine used according to its active ingredient, dosage form, and the patient’s condition.
Allopurinol — gout’s foundational urate-lowerer: shuts the xanthine-oxidase factory, dissolving deposits toward a numeric target (<6mg/dl; <5 with tophi). The twin famous rules: start low/titrate with colchicine cover (initiation mobilizes crystals and flares), and never START during an acute attack — but never STOP if already on. Early rash = same-day stop (SJS/DRESS, HLA-B*5801); azathioprine interaction is potentially lethal.
