Prescription Drug Index

Topamax is an antiepileptic drug prescribed to control both the mild attacks known as partial seizures and the severe tonic-clonic convulsions known as grand mal seizures. It is typically added to the treatment regimen when other drugs fail to fully control a patient’s attacks.

ADULTS

Topamax therapy usually begins with a dose of 50 milligrams once daily during the first week. The daily dosage is then increased each week until by the eighth week the patient is taking 200 milligrams twice a day.

For people with poor kidney function the dosage is usually cut in half. On the other hand those undergoing hemodialysis may need a supplemental dose.

If you are also taking Dilantin or Tegretol the dosage of Topamax may need adjustment. Likewise the doctor may adjust your dosage if you have liver problems.

CHILDREN

The usual daily dose for children 2 to 16 years of age is 5 to 9 milligrams for every 2.2 pounds of body weight divided into two doses. Topamax therapy usually begins with a dose of 25 milligrams (or less) once daily during the first week. The daily dosage is then increased each week until the doctor is satisfied with the patient’s response. It may take eight weeks to reach the ideal dose.
