Topiramate comes as a tablet, a sprinkle capsule (capsule that contains small beads of medication that can be sprinkled on food), and an extended-release (long-acting) capsule to take by mouth. The tablets and sprinkle capsules are usually taken with or without food once or twice a day. The extended-release capsules are usually taken with or without food once a day. Take topiramate at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take topiramate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
There is another medication with a name similar to the brand name for topiramate. You should be sure that you receive topiramate and not the similar medication each time you fill your prescription. Be sure that the prescription your doctor gives you is clear and easy to read. Talk to your pharmacist to be sure that you are given topiramate. If you think you were given the wrong medication, talk to your pharmacist. Do not take any medication unless you are certain it is the medication that your doctor prescribed.
Topiramate tablets have a bitter taste so you should swallow them whole. It is especially important that you not take topiramate tablets that have been broken for any length of time because tablets that are broken may lose their effectiveness over time.
The sprinkle and extended-release capsules (Qudexy XR brand only) may be swallowed whole or opened and poured over soft food. Swallow extended-release capsules (Trokendi XR brand only) whole; do not split, chew, or sprinkle on food.
To take the sprinkle capsules or extended-release capsules (Qudexy XR brand only) with food, follow these steps:
- Prepare a teaspoonful of soft food such as applesauce, custard, ice cream, oatmeal, pudding, or yogurt.
- Hold the capsule upright over the food.
- Twist off the top of the capsule and pour the entire contents onto the spoonful of food.
- Swallow the entire mixture immediately without chewing.
- Drink fluids right after swallowing to wash down the mixture and to be sure that you swallow all of it.
Your doctor will probably start you on a low dose of topiramate and gradually increase your dose, not more than once every week.
Topiramate may control your seizures or migraines but will not cure your condition. Continue to take topiramate even if you feel well. Do not stop taking topiramate without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop taking topiramate, you may have severe seizures, even if you have not had seizures in the past. Your doctor will probably decrease your dose gradually.
