Rhabdomyolysis following a short course of clarythromycin.

A healthy 5-year-old girl developed myalgia and an elevated creatine kinase concentration after 4 days of normal doses of clarithromycin. Myalgias resolved and creatine kinase values returned to normal following discontinuation of clarithromycin. No other precipitating factors or interacting drugs were identified; hence, clarithromycin was suspected as the cause of the rhabdomyolysis.
