Lorazepam is a benzodiazepine that acts as a γ-aminobutyric acid (GABA)–receptor agonist. Premature infants have been reported to experience seizurelike activity following the administration of lorazepam.1- 4 We report 2 cases of full-term infants, each without evidence of neurologic disorder, who received lorazepam for sedation and subsequently exhibited a seizurelike activity that occurred shortly after administration and resolved within 1 hour.
