Clinico-laboratory characteristics and outcome of patients with eucalyptus oil-induced/provoked seizures: A case series and systematic review of the published patients.

Seizures triggered by skin application, inhalation or ingestion of over-the-counter medications containing eucalyptus oil are known. We report five children who suffered likewise. We made a systematic search for all reported cases and performed a pooled analysis to provide a comprehensive estimate of the type of seizures, their management and outcome. In 110 cases (49 children), inhalational use was the most predominant, generalised tonic-clonic (the commonest semiology) and levetiracetam was the most common anti-convulsant treatment used. Most cases had an uneventful recovery. Adults were less likely to have prolonged and multiple seizures, requiring intensive care or mechanical ventilation.
