How to take it

Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

How much to take

Your doctor will decide the right dose for you depending on your medical conditions.

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.

Epilepsy
Adults - 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.

Children (2 years and over) - 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.

Migraine
Adults only - 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 per day, until the most suitable dose is reached.

How to take it

Swallow the tablet with a glass of water, with or without food.

When to take it

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

Try to take EPIRAMAX at about the same time each day. This will have the best effect on your condition. It will also help you to remember when to take it.

How long to take it

Continue taking EPIRAMAX for as long as your doctor tells you. EPIRAMAX can help to control your condition. So, you should keep taking the tablets regularly unless advised otherwise by your doctor.

If you forget to take it

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

Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.

Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.

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

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 (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much EPIRAMAX.

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

If you take too much EPIRAMAX, you may have headache, dizziness, light-headedness, drowsiness, convulsions, speech disturbances, double or blurred vision, difficulty with thinking, abnormal coordination, stomach pain, depression, agitation, faster breathing or you may lose consciousness.

While you are taking it

Things you must do

Tell all doctors, dentists and pharmacists who treat you that you are taking EPIRAMAX.

If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are taking EPIRAMAX.

Make sure you drink enough water during exercise and in hot weather when you are taking EPIRAMAX. EPIRAMAX has been known to cause kidney stones and drinking water may help prevent this.

Tell your doctor if you become pregnant while taking EPIRAMAX.

Take EPIRAMAX exactly as your doctor has prescribed. Otherwise, you may not get the benefits from treatment. Also, your doctor may think that it is not working and change your treatment unnecessarily.

Things you must not do

Do not stop taking EPIRAMAX or change the dosage, unless advised by your doctor.

Do not use EPIRAMAX to treat any other medical complaints unless your doctor tells you to.

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

Do not drive or operate machinery until you know how the medicine affects you.

Do not drink alcohol at the same time with EPIRAMAX.

Things to be careful of

Be careful driving or operating machinery until you know how EPIRAMAX affects you. EPIRAMAX may cause drowsiness, dizziness or other symptoms that could affect your ability to drive or operate machinery in some people.

Make sure you know how you react to EPIRAMAX before you drive, operate machinery or do anything else that could be dangerous if you are dizzy or light-headed.

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

Be careful with alcohol. Avoid drinking alcohol while taking EPIRAMAX, as alcohol may increase the risk of unwanted side effects, such as drowsiness.
