Key Points

Topamax (topiramate) is taken alone or with other medicines to control certain types of seizures due to epilepsy and for the prevention of migraine headaches. When taken twice a day, the medicine is usually taken in the morning and evening. When increasing your dose at the beginning of treatment, your dose may be taken only at night for a short while.

Topamax is classified as an anticonvulsant (seizure) medication, but is prescribed for other conditions, too, such as migraine. It is available as a generic option which may save you money. Copay cards from the manufacturer are also available.

When you first start treatment, you will start with a low dose of Topamax and slowly increase to the amount needed to control your seizures or migraine and to help limit side effects. Your dose is not usually increased more than once per week.

Topamax can cause drowsiness, dizziness and slowed reactions, so use caution when using this medication. Do not drive, operate machinery or engage in other potentially harmful activities until you know how you will respond to the medicine. Topamax can slow your thinking and motor skills, and may affect your vision.

Topamax used alone for seizures (partial-onset seizures and primary generalized tonic-clonic seizures):

  • Adults and children 10 years of age and older usually start taking Topamax twice a day, in the morning and in the evening. You start with a low dose of Topamax and slowly increase to the amount needed to control your seizures.
  • In children 2 to 9 years of age, treatment may begin with one dose given in at night. After one week, the doctor may increase the dose and give as two doses per day based upon how well the medicine is tolerated and the results. Doses in this age group are based on weight.
