Levetiracetam (LEV) is increasingly used as adjunctive anticonvulsant therapy because of apparent low toxicity. Somnolence, asthenia, headache, dizziness, and nervousness are the most frequently reported side effects (1). We describe a patient, predisposed to the development of the syndrome of inappropriate antidiuretic hormone secretion (SIADH), in whom hyponatremia developed after two challenges of LEV.
