1 What Topiramate tablets are and what they are used for

Topiramate belongs to a group of medicines called antiepileptic medicines. It is used

  • alone to treat seizures in adults and children over age 6
  • with other medicines to treat seizures in adults and children over age 2
  • to prevent migraine headaches in adults.

2 Before you take

Do not take Topiramate tablets and tell your doctor

  • if you are allergic (hypersensitive) to topiramate or any of the other ingredients of Topiramate tablets (see section 6).
  • for migraine prevention do not take if you are pregnant or you are able to become pregnant but you are not using effective contraception (see ‘Pregnancy and breastfeeding’ for further information).

Check with your doctor or pharmacist before taking Topiramate tablets if you

  • have kidney problems, especially kidney stones, or are having kidney dialysis
  • have a history of blood and body fluid abnormality (metabolic acidosis)
  • have liver problems
  • have eye problems especially glaucoma
  • have a growth problem
  • are on a high fat diet.

Other warnings

  • 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 other medicine containing topiramate that is given to you as an alternative to Topiramate tablets.
  • You may experience significant and continuing weight loss while taking Topiramate tablets. Therefore your weight should be checked regularly when using this medicine. If you are losing too much weight or if 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 tablets have had thoughts of harming or killing themselves. If at any time you have these thoughts, contact your doctor at once.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription, vitamins and herbal medicines. Topiramate and certain other medicines can affect each other. Sometimes the dose of some of your other medicines or Topiramate tablets 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 as Topiramate may make these pills less effective. If your menstrual bleeding changes, you have breakthrough bleeding or spotting, tell your doctor.
  • other antiepileptic medicines
  • risperidone, lithium, amitriptyline, venlafaxine (for depression)
  • hydrochlorothiazide, propranolol, diltiazem (for angina and high blood pressure)
