  • For migraine prevention if you are pregnant or if you are a woman of childbearing potential unless you are using effective contraception (see section ‘pregnancy and breastfeeding’ for further information). You should talk to your doctor about the best kind of contraception to use while you are taking Topiramate.

  • have liver problems
  • have eye problems, especially glaucoma
  • have a growth problem
  • are on a high fat diet (ketogenic diet)

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using this medicine.

It is important that you do not stop taking your medicine without first consulting your doctor.

You should also talk to your doctor before taking any medicine containing topiramate that is given to you as an alternative to topiramate.

You may lose weight if you use topiramate so your weight should be checked regularly when using this medicine. If you are losing too much weight or a child using this medicine is not gaining enough weight, you should consult your doctor.

A small number of people being treated with anti-epileptic medicines such as topiramate have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.

Topiramate can cause serious skin reactions, tell your doctor immediately if you develop a skin rash and/or blisters (see also section 4 ‘Possible side effects’).

Topiramate may in rare cases cause high levels of ammonia in the blood (seen in blood tests) which can lead to a change in brain function, especially if you are also taking a medicine called valproic acid or sodium valproate. Since this may be a severe condition, tell your doctor immediately if the following symptoms occur (see also section 4 ‘Possible side effects’):

  • difficulty thinking, remembering information, or solving problems
  • being less alert or aware
  • feeling very sleepy with low energy

At higher doses of Topiramate, the risk of developing these symptoms may increase.

Other medicines and Topiramate tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Topiramate and certain other medicines can affect each other. Sometimes the dose of some of your other medicines or topiramate will have to be adjusted.

Especially, tell your doctor or pharmacist if you are taking:

  • other medicines that impair or decrease your thinking, concentration, or muscle coordination (e.g. central nervous system depressant medicines such as muscle relaxants and sedatives).
  • birth control pills. Topiramate may make your birth control pills less effective. You should talk to your doctor about the best kind of contraception to use while you are taking Topiramate.

Tell your doctor if your menstrual bleeding changes while you are taking birth control pills and Topiramate.

Keep a list of all the medicines you take. Show this list to your doctor and pharmacist before you start a new medicine.

Other medicines you should discuss with your doctor or pharmacist include other anti-epileptic medicines, risperidone, lithium, hydrochlorothiazide, metformin, pioglitazone, glibenclamide, amitriptyline, propranolol, diltiazem, venlafaxine, flunarazine, St. John's wort (Hypericum perforatum) (a herbal preparation used to treat depression), warfarin used to thin the blood.

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using this medicine.

Topiramate tablets with food and drink

You can take Topiramate with or without food. Drink plenty of fluids during the day to prevent kidney stones while taking topiramate.You should avoid drinking alcohol when taking topiramate.

Pregnancy and breast-feeding

Migraine prevention

Topiramate can harm an unborn baby. You must not use Topiramate if you are pregnant. You must not use Topiramate for migraine prevention if you are a woman of childbearing potential unless you are using effective contraception. Talk to your doctor about the best kind of contraception and whether Topiramate is suitable for you. Before the start of treatment with Topiramate a pregnancy test should be performed.

Treatment of epilepsy:

If you are a woman of childbearing potential you should talk to your doctor about other possible treatments instead of Topiramate. If the decision is made to use Topiramate, you should use effective contraception. Talk to your doctor about the best kind of contraception to use while you are taking Topiramate. Before the start of treatment with Topiramate a pregnancy test should be performed.

Talk to your doctor if you wish to become pregnant.

As with other anti-epileptic medicines, there is a risk of harm to the unborn child if topiramate is used during pregnancy. Make sure you are very clear about the risks and the benefits of using topiramate for epilepsy during pregnancy.

  • If you take Topiramate during pregnancy, your baby has a higher risk for birth defects, particularly, cleft lip (split in the top lip) and cleft palate (split in the roof of the mouth). Newborn boys may also have a malformation of the penis (hypospadia). These defects can develop early in pregnancy, even before you know you are pregnant.
  • If you take Topiramate during pregnancy, your baby may be smaller than expected at birth. Talk to your doctor if you have questions about this risk during pregnancy.
  • There may be other medicines to treat your condition that have a lower risk of birth defects.
  • Tell your doctor straight away if you become pregnant while taking Topiramate. You and your doctor should decide if you will continue to take Topiramate while you are pregnant.

Breast-feeding

The active substance in Topiramate passes into human milk. Effects have been seen in breastfed babies of treated mothers, including diarrhea, feeling sleepy, feeling irritable, and poor weight gain. Therefore, your doctor will discuss with you whether you abstain from breast-feeding or whether to abstain from treatment with Topiramate. Your doctor will take into account the importance of the medicine to the mother and the risk for the baby.

Mothers who breastfeed while taking topiramate must tell the doctor as soon as possible if the baby experiences anything unusual.

Ask your doctor or pharmacist for advice before taking any medicine.
