Colchicine is contraindicated in which disorder?

Colchicine is contraindicated in which disorder?

• A. Renal failure
• B. Hypertension
• C. Hyperlipidemia
• D. Hypothyroidism

Answer: (A)

Colchicine has a very narrow margin between therapeutic and toxic levels, and its clearance relies heavily on the kidneys. When renal function is impaired, the drug is cleared more slowly and can accumulate, increasing the risk of serious toxicity such as severe gastrointestinal symptoms, bone marrow suppression, and neuromuscular toxicity. Because of this accumulation risk, renal failure constitutes a contraindication to using colchicine (or requires careful adjustment and monitoring). The other conditions listed do not inherently prevent colchicine use in the same way, since they do not majorly affect renal clearance.
