How should this Topamax medicine be used?
Topamax/Topiramate comes as a tablet to take by mouth. Topamax usually is taken twice a day. Topamax may be taken with or without food. Your doctor may adjust your Topamax dosage over the first few weeks, until your seizures are better controlled. Follow the Topamax directions on your Topamax prescription label carefully, and ask your doctor or Topamax pharmacist to explain any part you do not understand. Take Topamax/topiramate exactly as directed. Do not take more or less of Topamax or take Topamax more often than prescribed by your doctor.
Topamax/Topiramate controls epilepsy but does not cure it. Continue to take Topamax/topiramate even if you feel well. Do not stop taking Topamax/topiramate without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will decrease your Topamax dose gradually. This Topamax drug must be taken regularly for a few weeks before its full effect is felt.
Topamax/Topiramate has a bitter taste, so do not break or chew the tablet. If you cannot swallow the tablet, crush it, mix it with applesauce or oatmeal, and then eat it immediately.
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.
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.
