Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about TAMATE tablets.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

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

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

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

What TAMATE is used for

The name of your medicine is TAMATE. It contains the active ingredient topiramate.

TAMATE belongs to a group of medicines known as antiepileptics. TAMATE is used for the treatment of various types of seizures in adults and children, aged 2 years and over.

It can also be used for the prevention of migraines in adults. TAMATE is not used to treat severe migraines that come on suddenly (acute).

It prevents seizures and migraines by acting on the nerves and chemicals in the brain.

Your doctor may prescribe TAMATE on its own, or in addition to another medicine for controlling your seizures or migraines.

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

Information available indicates that there is an association between the use of TAMATE in humans during pregnancy and birth defects including cleft lip/ palate, and neurodevelopmental disorders such as autism spectrum disorders and intellectual disability. However, it is very important to control your fits while you are pregnant. If it is necessary for you to take TAMATE, your doctor can help you decide whether or not to take it during pregnancy.

How to take TAMATE

How to take it

Follow your doctor's instructions about when and how to take TAMATE

You can take the tablets with or without food. Always swallow the tablets whole with plenty of water.

The doses shown below are the usual recommended doses. However, your doctor may tell you to take higher or lower doses. Your doctor will start with a low dose and slowly increase the dose to the lowest amount needed to control your epilepsy.

At the start of treatment TAMATE may be taken once a day, preferably at night. After the dose is increased, it is taken twice a day.

You should continue taking TAMATE until your doctor tells you to stop. Before stopping, it is recommended that the dose be reduced gradually.

Adults

Epilepsy

Treatment starts at a low dose of 25 mg to 50 mg per day. The dose is then gradually increased by 25 mg to 100 mg over weekly periods or longer, until the most suitable dose is reached.

Migraine

Treatment starts at a low dose of 25 mg nightly for one week. The dose is then increased over weekly periods or longer by 25 mg/day, until the most suitable dose is reached.

Children (2 years and over) - epilepsy only

Treatment starts at 25 mg or less per day, depending on the body weight. This dose is then gradually increased over weekly periods or longer, until the most suitable dose is reached.

If you forget to take it

Take your dose as soon as you remember, and then continue to take it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you have missed more than one dose, or are not sure what to do, check with your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre for advice, or go to Accident & Emergency at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Things to be careful of

Changes to your medication

If you are seizure free or your seizures are well controlled, a reduction in your dose, discontinuation or substitution of your current medication should first be assessed by your doctor and pharmacist, and any changes should be implemented gradually.

Effects on thoughts and behaviour

Medicines used to treat epilepsy can increase the risk of suicidal thoughts and behaviour. If you experience feelings of deep sadness and unworthiness (depression) or a worsening of these feelings, any unusual changes in your mood or the emergence of suicidal thoughts, behaviour or thoughts of self-harm, you should report this to your doctor immediately.

Decreased sweating and elevation in body temperature

TAMATE may cause decreased sweating and increased body temperature (fever). People, especially children, should be watched for signs of decreased sweating and fever, especially in hot temperatures. Some people may need to be hospitalized for this condition. Call your healthcare provider right away if you have a high fever, a fever that does not go away, or decreased sweating.

Effects on driving and operating machinery

TAMATE may cause drowsiness, dizziness or other symptoms which could affect your ability to drive or operate machinery. It may also cause visual disturbances and/ or blurred vision. Make sure you know how you are affected by this medicine before you drive or use machinery.

Particular care is recommended when you first start taking TAMATE or if the amount of TAMATE or any other medicine you are taking is increased or decreased.

Effects of food and alcohol

TAMATE can be taken with or without food. Do not drink alcohol while taking TAMATE. Alcohol may increase the risk of unwanted side effects, such as drowsiness.
