Hypokalaemia (first report), impaired consciousnessand vomiting: case report
A 15-year-old girl intentionally self-administered six 10-mgtablets of zaleplon [Selofen; total dose 1.2 mg/kg] in a suicideattempt and, 1.5 hours later, started vomiting copiously andwas subsequently hospitalised. On admission, her HR wasregular at 108–115 beats/minute, and she had slurred speech,drowsiness and delayed verbal reactions. About 2.5–3 hoursafter she had taken zaleplon, she developed hypotonia, dilatedpupils with a slow response to light, and ataxia. Biochemicalanalyses identified hypokalaemia (3.2 mmol/L). Afterapproximately 4 hours’ maintenance therapy, her ataxia,hypotonia and slurred speech disappeared; her drowsinessresolved after a further 2–3 hours. She was discharged after36 hours’ observation.
