1. What this medicine is and what it is used for
Emeside Capsules contain ethosuximide which is an anti-epileptic.
It is used to control epilepsy in children and adults.
Epilepsy is a condition where you have repeated seizures (fits).
Ethosuximide is used to control brief, sudden loss of consciousness (absence seizures, also
called petit mal), and uncontrolled jerking movements (myoclonic seizures).

other ingredients (see Section 6)

Take special care with Emeside Capsules
Before taking the capsules, tell your doctor if you:
 have liver or kidney disease
 are pregnant or planning a pregnancy, or if you are breast-feeding.
A small number of people being treated with anti-epileptics such as ethosuximide have had
thoughts of harming or killing themselves. If at any time you have these thoughts, immediately
contact your doctor.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other
medicines, including medicines obtained without a prescription, and herbal preparations.
Some medicines may be affected by Emeside Capsules or they may affect how well Emeside
Capsules will work. Tell your doctor or pharmacist if you are taking:
 isoniazid , a medicine used for certain types of infections
 other medicines to control epilepsy, in particular carbamazepine, phenytoin, sodium
valproate. If Emeside Capsules are to replace your other medicines for epilepsy, your
doctor will withdraw these gradually to avoid seizures.



Pregnancy and breast-feeding
Ethosuximide may affect the unborn baby.
However, it is very important to control your fits while you are pregnant.
If you need to take ethosuximide, your doctor can help you decide whether or not to take it
during pregnancy.

Ask your doctor for advice before taking any medicine.
