Epilepsy medicines available in the United Kingdom

Print this page

The main way of treating epilepsy is with epilepsy medicines. You may hear these referred to as anti-epileptic drugs (AEDs).

The following information is taken mainly from the British National Formulary (BNF) Number 74 (September-March 2018). Published by the British Medical Association and the Royal Pharmaceutical Society of Great Britain, it is updated twice a year. 

The medicines listed are those usually prescribed for everyday seizure control. Other medicines, such as diazepam or midazolam, are available for emergency use. We have not included emergency medicines on this list.

Under the heading Indications in epilepsy, the main use of each medicine is given. This information is taken from the BNF. Sometimes a doctor may prescribe medicines for other seizure types than those listed. Epilepsy medicines are available in a number of different formulations such as tablets, capsules, chewtabs, sugar-free liquid, syrup, dispersible tablets, crushable tablets and sprinkle capsules.

There are various ways to get further information about epilepsy medicines, side-effects, and dosages:
