WHY is this medicine prescribed?
Topiramate is used alone or with other medications to treat certain types of seizures including primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) and partial onset seizures (seizures that involve only one part of the brain). Topiramate is also used with other medications to control seizures in people who have Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). Topiramate is also used to prevent migraine headaches but not to relieve the pain of migraine headaches when they occur. Topiramate is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.
HOW should this medicine be used?
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:
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.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with topiramate and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs) or the manufacturer's website to obtain the Medication Guide.

What should I do IF I FORGET to take a dose?
If you are taking topiramate tablets or sprinkle capsules, take the missed dose as soon as you remember it. However, if it is less than 6 hours before you are scheduled to take your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Tablets and extended-release capsules should be stored at room temperature and away from excess heat and moisture (not in the bathroom). Sprinkle capsules should be stored at or below 77°F (25°C). Never store broken tablets, capsules, or mixtures of sprinkles and soft food. These should be used right away or discarded.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.http://www.upandaway.org
