Correct answer: B — 6 months

When commencing urate-lowering therapy, anti-inflammatory prophylaxis (colchicine 500 mcg daily is preferred) should be continued for a minimum of 6 months to prevent mobilisation flares that occur as tissue urate deposits dissolve. Some guidelines recommend extending to 3–6 months after achieving target serum urate. Ongoing prophylaxis beyond 6 months may be needed if the patient continues to experience flares. NSAIDs or low-dose prednisolone are alternatives if colchicine is contraindicated.
