Topiramate is an antiepileptic drug with a beneficial clinical effect on various seizure types. Topiramate does not seem to be associated with serious adverse effects and is also well tolerated in pediatric patients. Only few cases of hypohidrosis have been described. This report presents one young patient with complex partial seizures who was medicated with topiramate when she developed fatigue, headache, intermittent hyperthermia, inability to produce sweat secretion, and dryness of the skin. Reduced sweat response was determined using the Wescor Macroduct collection procedure. Topiramate was discontinued, and within 3 weeks a repeat sweat test was completely normal. At that time, clinical signs had also disappeared. Hypohidrosis is an uncommon and reversible side effect reported in association with topiramate therapy. It is rare in patients on monotherapy. Although a definite causal relationship still needs to be established, this side effect might be attributed to an autonomic dysfunction by inhibition of isoenzymes of carbonic anhydrase localized in human eccrine sweat glands.
