The name of your medicine is Zarontin. It comes as oblong amber coloured capsules containing a clear liquid and printed P-D in white on the side. Each capsule has 250 mg of the active ingredient Ethosuximide PhEur.

The capsules also contain the following inactive ingredients: polyethylene glycol 400 E124 E104 gelatin and glycerin.

The active ingredient Ethosuximide PhEur is one of the group of medicines called anti-epileptic drugs which are used in the treatment of epilepsy.

The product licence holder is Parke Davis & Company and the manufacturer is Parke Davis & Co Ltd at Usk Road Pontypool Gwent NP4 0YH.

Zarontin can be used for the prevention of absence seizures (petit mal epilepsy) and may be taken with other anti-epileptic drugs.

Before you start to take Zarontin:

Are you pregnant trying to become pregnant or breastfeeding?

Have you ever had a reaction to Zarontin or other similar drugs?

Are you taking any other anti-epileptic medicines that your doctor may not be aware of ?

Do you suffer from kidney or liver disease? Zarontin may affect your liver and kidneys. Your doctor may take regular blood samples to test for this.

If you answer YES to any of these questions do not take the capsules. Talk to your doctor or pharmacist at once.

Follow your doctor s instructions exactly and never change the dose yourself. Your doctor will have decided what dose of Zarontin is right for you.

The dosage of Zarontin varies from one person to another. Adults and children over six usually start on two capsules a day and build up slowly to four or six capsules a day. Even higher doses are sometimes needed.

Children under six usually take Zarontin syrup.

Try to take the medicine at the same time every day.

If you forget to take a dose take another as soon as you remember unless it is time for your next dose. Do not take 2 doses at the same time.

If you accidentally take too much Zarontin, tell your doctor at once. If you can t do this go to the nearest hospital casualty department. Take along any capsules that are left, the container and the label so that the hospital staff can easily tell what medicine you have taken.

Do not stop taking Zarontin or change the amount you take unless your doctor tells you to.

You might notice this first as being unable to fight off infections, fever and sore throat or bruising and bleeding.

If your doctor decides to end your treatment return the leftover capsules to your pharmacist. Only keep them if your doctor tells you to.
