Topiramate
Summary
Topiramate is used to treat epilepsy, which is a disorder causing seizures, and to prevent migraines, which are severe headaches often accompanied by nausea and sensitivity to light.
Topiramate stabilizes electrical activity in the brain, which helps control seizures and reduce migraine frequency. It affects neurotransmitters, which are chemicals that transmit signals in the brain.
The usual starting dose for adults is 25 mg once daily, often in the evening. The dose may be gradually increased by a doctor. Topiramate is taken orally, with or without food, and tablets should be swallowed whole.
Common side effects include tingling in the hands and feet, loss of appetite, weight loss, and dizziness. These effects are usually mild to moderate.
Topiramate should not be used if allergic to it. Caution is needed for conditions like kidney stones. It can cause vision problems and increase the risk of metabolic acidosis, which is a condition where too much acid builds up in the body.
