A Common Drug With a Dangerous Side Effect: Acute Rhabdomyolysis Caused by the Synergistic Effect of Isotretinoin and Exercise in an Adolescent

摘要

Isotretinoin or 13-cis-retinoic acid, a derivative of vitamin A, is a highly effective?therapy?for severe?and resistant acne.?Its usage is restricted worldwide because of its teratogenic potential. The most common side effects are dermatologic, cheilitis, increased skin fragility, and susceptibility to sunburns. Rare side effects include myalgias and arthralgias.?It also causes transient laboratory abnormalities such as elevated creatine kinase (CK). Very few cases of isotretinoin-induced severe muscle injury leading to rhabdomyolysis have been reported in the literature. We report a 15-year-old adolescent who developed rhabdomyolysis after a bout of vigorous exercising while on long-term isotretinoin therapy.
