Abstract
Neuromyopathy is a rare side effect of chronic colchicine therapy, most often occurring in patients with chronic renal failure. Drugs interacting with colchicine metabolism through CYP(3)A(4) and P-glycoprotein can accelerate accumulation and toxicity. We describe a case of an interaction between clarithromycin and colchicine resulting in acute neuromyopathy, and we conclude that combined use of macrolides and colchicine should be avoided.
