Valproic acid (VPA) is frequently used as an antiepileptic drug. Several side effects are known. We report on a child with onychomadesis as a possible side-effect of treatment with VPA. Normal nail growth was observed after stopping VPA. The pathomechanism of onychomadesis due to VPA treatment remains unclear.
