[Heat stroke and topiramate]. / Coup de chaleur et topiramate.

Heatstroke, which is a major disorder related to environmental hyperthermia, is a rare event in children. The risk is increased with predisposing medical conditions and specific medications. We report the case of a 10-year-old epileptic patient, who received topiramate. Topiramate causes hypohydrosis and hyperthermia. We suggest that topiramate treatment may be a risk factor for heatstroke.
