Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Valprease. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking Valprease against the benefits they expect it will have for you.

Talk to your doctor or pharmacist if you have any concerns about taking this medicine.

Keep this leaflet with your medicine. You may need to read it again.

What Valprease is used for

Valprease tablets contain sodium valproate as the active ingredient, which belongs to a group of medicines called anticonvulsants.

Valprease is used to control epilepsy. Epilepsy is a condition where you have repeated seizures or fits. There are many different types of seizures, ranging from mild to severe. It is 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.

Ask your doctor if you have any questions about why it has been prescribed for you. Your doctor may have prescribed it for another reason.

There is no evidence that it is addictive.

This medicine is available only with a doctor's prescription.

Before you start to take it

Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.

If you are a female patient of child-bearing age, make sure you talk to your doctor about the risks associated with taking Valprease during pregnancy.

Tell your doctor if you are pregnant or intend to become pregnant. Valprease may affect your developing baby if taken in the first trimester of pregnancy as it is suspected of causing an increased risk of malformations in the exposed foetus. Also, children born to mothers who take Valprease throughout their pregnancy may be at risk of impaired cognitive development or withdrawal syndrome. However, do not stop taking Valprease unless your doctor says so as there are risks to the mother and the child from uncontrolled epilepsy or uncontrolled mania episodes.

Your doctor may want to adapt your treatment and prescribe dietary supplements of folate.

Your doctor will discuss the risks and benefits of taking Valprease if you are pregnant.

Tell your doctor if you are breast-feeding or wish to breast-feed. Medicines used in the treatment of epilepsy pass into breast milk. Your doctor will discuss the risks and benefits of taking Valprease when breast-feeding.

Tell your doctor if you drink alcohol. If you have more than 2 drinks per day, you may be putting yourself at risk of a seizure or fit.

Tell your doctor if you have or have had any medical conditions especially the following:

  • liver problems (any hepatic insufficiency or disease)
  • pancreas problems
  • kidney problems
  • urea cycle disorders
  • ornithine transcarbamylase (OTC) deficiency
  • carnitine palmitoyltansferase (CPT) type II deficiency
  • systemic lupus erythematosus (a disease affecting the skin, joints and kidneys)
  • family history of genetic problem causing mitochondrial disorder.

Tell your doctor if you plan to have surgery.

If you have not told your doctor or pharmacist about any of the above, tell them before you start to take Valprease.

Taking other medicines

Use in children

If Valprease has been prescribed for your child, ensure that your child’s doctor is aware of any other medications that your child is taking, e.g. other medicines to treat epilepsy or aspirin. Children, especially young children, can be more sensitive to some of the side effects of this medicine.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Valprease.

How to take it

How much to take

Your doctor will tell you how many tablets you need to take each day. This depends on your age, your condition and whether or not you are taking any other medicines.

Your doctor may recommend that you start with a low dose and slowly increase the dose to the lowest amount needed to control your condition.

Follow all directions given to you by your doctor and pharmacist carefully. If you take the wrong dose, VALPREASE may not work as well.

How to take it

Swallow the tablets whole, with or after food, with a little water if necessary. Do not crush or chew the tablets. VALPREASE tablets have a special coating to stop them dissolving until they have gone through the intestines. If you crush or chew the tablets, the coating is destroyed and they will not work as well.

When to take it

Take VALPREASE at about the same time each day. This will have the best effect and also help you remember when to take it.

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 you missed. This may increase the chance of you getting unwanted side effects.

Ask your doctor or pharmacist if you are not sure what to do.

How long to take it

Keep taking Valprease for as long as your doctor recommends.

This medicine helps control your condition but does not cure it. To properly control your condition, it must be taken regularly.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Valprease. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of overdose are variable and include coma, below normal or absent reflexes, trouble breathing and feeling dizzy or drowsy.

While you are taking it

Things you must do

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Valprease.

Tell your doctor immediately if you become pregnant while taking this medicine.

If you have to have surgery or emergency treatment that requires a general anaesthetic, tell your doctor or dentist that you are taking Valprease.

Be sure to keep all of your doctor’s appointments so that your progress can be checked. Your doctor will check your progress and may want to take some tests from time to time. This helps prevent unwanted side effects.

Things you must not do

Do not stop taking Valprease or lower the dose without checking with your doctor.

Do not take more than the recommended dose unless your doctor tells you to.

Do not use this medicine to treat any other conditions unless your doctor tells you to.

Do not give it to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how Valprease affects you. This medicine may cause dizziness or drowsiness in some people, especially at the beginning of treatment. If either of these occurs, do not drive, operate machinery or do anything else that could be dangerous.

Children should not ride a bike, climb trees or do anything else that could be dangerous if they are feeling drowsy or sleepy.

Be careful drinking alcohol. Combining Valprease and alcohol can make you more drowsy or dizzy. Your doctor may suggest you avoid alcohol while you are being treated with this medicine.

Things to consider about contraception

Use an effective method of contraception and consult your doctor before planning pregnancy. Unplanned pregnancy may not be desirable in patients taking anticonvulsants. You should use an effective method of contraception.

If you are planning pregnancy, your doctor may want you to start taking folate tablets to help prevent neural tube defects in the baby.

Valprease should have little effect on the oral contraceptive pill, however tell your doctor if you are taking it.

Side effects

Keep the tablets in the protective blister foil until it is time to take them. If you take the tablets out of the pack they may not keep as well.

Store the medicine in a cool dry place where the temperature stays below 25°C.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

Keep this medicine where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
