Emeside syrup discontinued

28 Apr 2017

Essential Pharma has discontinued its version of ethosuximide syrup, Emeside.

If you take Emeside syrup, you will need to switch to a generic version of ethosuximide syrup. This is because the other branded version of the syrup, called Zarontin, has also been discontinued.

If you have any concerns about this, speak to your doctor, epilepsy nurse of pharmacist.

Hi all, we are having terrible trouble obtaining this syrup in Surrey. None of the pharmacies will stock it due to cost (now about £173 per bottle up from £4.40 when someone else had a share of the market....) and even if they order it in, a lot of their stockist depots don't have it. It took me 4 hours to locate the SINGLE bottle of 200mls in Surrey on Friday. I am currently in discussions with a couple of local pharmacies to stockpile for us, but our Consultant today said that all her patients (children) are struggling to obtain it. Any tips on how to make it more easily available? thanks

Hi Joanna 

It is a worrying time when medicine isn’t readily available. 

We have checked the availability of the generic version of ethosuximide and there are no supply problems. You could tell your pharmacy it is available for the wholesalers Alliance and AAH

Even if the price has increased, your chemist has a duty to fulfil your prescriptions.  If your pharmacist isn’t willing to buy large quantities of this medicine, could you come to some agreement that you will phone and let them know a week before you are due to put your prescription in.

You could also talk to the practice manager at your GPs. They may have a good relationship with a local pharmacy. 

If you are unhappy with the service you received at your pharmacy, speak or write to your pharmacist (or the manager of the pharmacy they work for) first. If you feel too uncomfortable to complain to the pharmacist directly then you can make a complaint to NHS England.

If we can be of any more help, please feel free to contact our helpline team directly. You can email helpline@epilepsy.org.uk or phone the Epilepsy Action Helpline freephone 0808 800 5050. Our helpline is open Monday to Friday, 8.30am until 5.30pm.

Hi Abdellah

I am guessing your daughter is taking the liquid. You don’t say how old she is. I wonder if she would get on any better with the capsules?

Here is the general information about Emeside: http://www.medicinesforchildren.org.uk/ethosuximide-preventing-seizures

And here are some suggestions about how to help your child take medicine. And here is their information on helping your child to swallow tablets or capsules: http://www.medicinesforchildren.org.uk/sites/default/files/content-type/leaflet/pdf/Guide%20to%20swallowing%20tablets%2030.11.17.pdf

I hope this information helps.
