Most febrile seizures are brief and the seizure has usually ended prior to the child being assessed.
If the seizure has not stopped, treatment with intravenous lorazepam (0.1 mg/kg over 1 min; maximum dose 4 mg), intravenous diazepam (0.3 mg/kg over 2 min; maximum dose 5 mg in infants and 10 mg in older children) or buccal midazolam (0.5 mg/kg; maximum dose 10 mg) is indicated.
Rectal diazepam (0.5 mg/kg; maximum dose 10 mg) may also be administered, but is less effective than buccal midazolam.
