Reversible myopathy due to labetalol.
A severe, generalized myopathy developed in 2 children treated with labetalol. An 11-year-old girl and a 14-year-old boy demonstrated proximal weakness and markedly elevated creatine kinase levels during labetalol therapy. Clinical improvement began immediately when labetalol administration was halted; muscle strength was normal within 2 months. Muscle biopsies were consistent with rhabdomyolysis.
