What NOUMED TOPIRAMATE is used for
NOUMED TOPIRAMATE tablets contain the active ingredient topiramate.
Topiramate belongs to a group of medicines called anti-epileptics. These drugs prevent seizures and migraines by acting on the nerves and chemicals in the brain.
NOUMED TOPIRAMATE is used to treat various types of epilepsy in adults and children over 2 years of age, and to prevent migraines in adults.
This medicine is available only with a doctor’s prescription.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

How to take NOUMED TOPIRAMATE
How much to take
The amount of NOUMED TOPIRAMATE you or your child will take is determined by your doctor.
Your doctor will start with a low dose and slowly increase the dose to the lowest amount needed to control your condition. The changes in dose are made at intervals of one week or longer to help you cope with its effects.
The doses shown below are the recommended doses.
The dose depends on whether NOUMED TOPIRAMATE is taken alone (monotherapy), or used with another medication (add-on therapy).
In adults, treatment starts at 25 mg to 50 mg per day then increased by 25 to 100 mg until a suitable effective dose of 100 to 400 mg is reached.
In children 2 years or older, treatment starts at 25 mg or less per day depending on the child’s body weight then gradually increased to 3 to 9 mg per day for every kg weight.
Migraine (adults only)
Treatment starts at 25 mg per day then increased by 25 mg in intervals of one week or longer until an effective dose of 50 to 200 mg per day is reached.
Ask your doctor or pharmacist if you are unsure of the correct dose for you or do not understand the instructions. They will tell you exactly how much to take.
Follow all directions they give you carefully. If you take the wrong dose, NOUMED TOPIRAMATE may not work as well and your condition may not be adequately controlled.
How to take it
Swallow the tablets whole with plenty of water.
You can take the tablets with or without food.
When to take it
At the start of treatment, NOUMED TOPIRAMATE may be taken once a day, preferably at night. After the dose is increased, it is taken twice a day.
Take your medicine at about the same times each day. Taking it at the same times each day will have the best effect. It will also help you remember when to take it.
How long to take it
You should continue taking NOUMED TOPIRAMATE until your doctor tells you to stop.
Before stopping, it is recommended that the dose be reduced gradually.
If you forget to take it
Take your dose as soon as you remember, and 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 that you missed. This may increase the chance of you getting an unwanted side effect.
If you have missed more than one dose, or are not sure what to do, ask your doctor pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
