Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Topiramate can be taken with or without food.
Swallow the tablet whole and do not crush, chew, or break it. The Trokendi XR extended-release capsule must be swallowed whole. Do not break or open.
If you cannot swallow a Qudexy XR or Topamax Sprinkle Capsule whole, open it and sprinkle the medicine into a spoonful of applesauce or other soft food. Swallow the mixture right away without chewing. Do not save it for later use.
Carefully follow the swallowing instructions for your medicine.
Topiramate doses are sometimes based on weight in children. Your child's dose needs may change if the child gains or loses weight.
Drink plenty of liquids while you are taking topiramate, to prevent kidney stones or an electrolyte imbalance.
You will need frequent medical tests. If you need surgery, tell the surgeon ahead of time that you are using topiramate. Any medical care provider who treats you should know that you take seizure medication.
Do not stop using topiramate suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Call your doctor if your seizures get worse or you have them more often while taking topiramate.
Store at cool room temperature away from moisture, light, and high heat.

What happens if I miss a dose?
Take the medicine as soon as you can. Do not take two doses at one time. Skip a missed Topamax dose if your next dose is due in less than 6 hours.
Call your doctor if you have missed more than one dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of topiramate can be fatal. Overdose can cause drowsiness, agitation, depression, double vision, thinking problems, problems with speech or coordination, fainting, and seizure (convulsions).
