Key Points

  • Seizures can occur as an adverse effect of a large number of drugs from different pharmacological categories.
  • No characteristic clinical features differentiate drug-induced seizures from idiopathic epileptic seizures.
  • Use of drugs known to cause seizures should be avoided in patients with predisposition to seizures.
  • Most drug-induced seizures resolve after discontinuation of the offending drugs, but some patients require supplementary treatment.
  • Intravenous diazepam is the most frequently used drug for the control of drug-induced seizures.
