This information is a guide only, and lists the usual daily doses of anti-epileptic drugs (AEDs). The dose taken may be different to those listed above.
Treatment of neonatal seizures (from birth to 28 days of age) is not covered.
Most doses are listed as ‘mg/kg’: this means milligrams of AED per kg of the child’s weight.
Children starting AED treatment at the age of 12 may start on adult doses. Some AEDs are only used for children aged 12 and over (including eslicarbazepine acetate, lacosamide, perampanel, pregabalin, retigabine and tiagabine).
Some AED doses are listed as ‘twice daily’ (for example ‘5mg/kg twice daily’). This means that the dose listed is taken each time (and so the total daily dose will be double that listed).
Some AED doses are listed as ‘divided into 2 (or 3) doses’ (for example ‘25 - 30mg/kg daily divided into 2 doses’). This means that the total amount listed is divided into two to give the dose taken each time.
‘Effective’ means the seizures it works for. ‘Monotherapy’ means the AED is taken on its own. ‘Add-on therapy’ means the AED is taken alongside other AEDs. ‘Tolerance’ means that a drug becomes less effective the longer you take it.
