Frequently asked questions
Should I take allopurinol during a gout attack?
Do not start it during an attack, and if you already take it, do not stop. Starting can briefly worsen a flare, so it is begun after an attack settles, often with cover.
Do I need gout medicine for life?
Urate-lowering treatment is often long-term to keep uric acid low and prevent attacks and joint damage. Diet helps but usually is not enough alone.
