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 73 (March-September 2017). 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:

Thank you for the information. I become tolerant to any anticonvulsant after about 1 year and need to switch to another. It would be helpful if you would also indicate the mechanism of action of each drug and the typical length of the period of effectiveness is before patients become tolerant.

Hi Neil
Thank you for your comment.

As everyone is individual and not everyone experiences tolerance to their epilepsy medicine, it’s not possible for us to put time periods

We do however in our treatment information cover many issues about treating epilepsy with epilepsy medicine. This includes information on, how long it takes for epilepsy medicine to work and changes in how well epilepsy medicine works.

epilepsy.org.uk/info/treatment/anti-epileptic-drug-treatment#how-long-it-takes-for-aeds-to-work

We do not talk about the different modes of action of different epilepsy medicines as we are not qualified to do this. If someone wanted such information we would suggest they contact their local pharmacist.

As you have experienced problems with your own treatment, I hope you are still seeing an epilepsy specialist.  This will enable them to review your treatment and if you have tried various types of epilepsy medicines, it may be the specialist could look into other treatment options for you.

epilepsy.org.uk/info/treatment/other-ways-treating-epilepsy

If you are not under a specialist, you will need to ask your family doctor to refer you. This would usually be to a neurologist. The ideal would be to someone with a specialist interest in epilepsy, as there are many different neurological conditions, and neurologists tend to specialise in different ones.
