Colchicine is used as prophylaxis when initiating urate-lowering therapy to accomplish what?

• A. To prevent a gouty flare during initiation of therapy
• B. To rapidly lower serum uric acid
• C. To treat chronic gout pain
• D. To prevent kidney stone formation

Answer: (A)

Starting urate-lowering therapy can mobilize stored urate crystals into the bloodstream and joints, triggering acute gout flares. Colchicine given at low doses during this initiation period acts by inhibiting neutrophil activity and the inflammatory response, reducing the risk and severity of these flares. So its prophylactic use is to prevent a gout flare when therapy is started, not to rapidly lower uric acid, treat chronic pain, or prevent kidney stones.
