What Valprease is used for
Valprease is a medicine used to for the treatment of epilepsy in adults and children.
Epilepsy is a condition where you have repeated seizures (fits). There are many different types of seizures, ranging from mild to severe.
Valprease belongs to a group of medicines called anticonvulsants.
These medicines are thought to work by controlling brain chemicals which send signals to nerves so that seizures do not happen.
Valprease may also be used to control mania, a mental condition with episodes of overactivity, elation or irritability.
Valprease may be used alone or in combination with other medicines to treat your condition.
Your doctor, however, may have prescribed Valprease for another reason.
Ask your doctor if you have any questions about why it has been prescribed for you.
There is no evidence that Valprease is addictive.
This medicine is available only with a doctor's prescription.

How to take it
How much to take
Your doctor will tell you how much to take, and in what form (liquids or tablets) you should take it. This may depend on your age, your conditionand whether or not you are taking any other medicines.
Your doctor may recommend that you start with a low dose of Valprease and slowly increase the dose to the lowest amount needed to control your condition.
Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.
Follow the instructions they give you. If you take the wrong dose, Valprease may not work as well.
How to take it
Swallow the tablets whole with a glass of water or other liquid.
Do not crush or chew the tablets. The tablets have a special coating to stop them dissolving until they have gone through the stomach and into the intestines. If you chew them, the coating is destroyed.
When to take it
Your doctor will advise you when to take Valprease.
Always follow your doctor's instructions.
Take Valprease at about the same time each day. Taking your tablets at the same time each day will have the best effect. It will also help you remember when to take the tablets.
If you are not sure when to take it, ask your doctor.
How long to take it
Continue taking your medicine for as long as your doctor tells you. Valprease helps control your condition but does not cure it. Therefore you must take it every day.
If you forget to take it
Always remember to take your prescribed dose otherwise you may find that either your seizures or manic symptoms may return.
If you forget a dose, take your next dose as usual. Do not take a double dose to make up for the dose that you missed. This may increase the chance of your getting unwanted side effects.
If you are not sure what to do, ask your doctor or pharmacist.

What do I need to consider about contraception?

If you are a girl or woman of childbearing age, you must use at least one effective method of birth control (contraception) without interruption during your entire treatment with Valprease. Your doctor should discuss with you the most appropriate method of contraception for you
Valprease should have little effect on the oral contraceptive pill, however, you should let your doctor know that you are taking it.
