Ethosuximide syrup

Dear Patient

The NHS carries out regular reviews of medicines to make sure that patients continue to receive high quality and effective treatment that costs the NHS less.

The latest review involves a change in one of the medications for epilepsy on your prescription. The full details of the change are shown below. The new medication will be given to you when you collect your next repeat prescription.


WHAT IT WILL CHANGE TO: Emeside® 250mg/5ml syrup

This new medicine contains the same active ingredient as your old medication so please continue to take it in the same way and at the same dose as before.

Please finish using all the medicine you currently have before starting on the new Emeside® syrup.

As this is a syrup, it may not be suitable for you if you have diabetes. Check your blood glucose levels after switching to Emeside® syrup and contact your GP surgery if you have any concerns. Your current medicine may already contain sugar or you may be already receiving this brand from your pharmacy as it is often supplied by pharmacies when a brand is not specified on a prescription.

Good oral hygiene is important when taking medicines containing sugar.

You should notice no difference in how the new version of your medicine works for your epilepsy as it is equally effective and has the same side effects listed as your old version.

We would also like to take this opportunity to remind you to order only the medicines you need whenever you submit your repeat prescription request.

If you are concerned or wish to discuss the matter, please do not hesitate to contact the practice.

Yours sincerely
