What is Zonisamide?

Zonisamide, marketed under several brand names including Zonegran, is a carbonic anhydrase inhibitor and a sulfonamide anticonvulsant. It is used as an adjunctive treatment for partial seizures in adults with epilepsy.


Zonisamide Uses:

Zonisamide is used in combination with other medications to prevent and control seizures (epilepsy). It works by inhibiting certain processes in the brain to reduce the occurrence of seizures.

How to Take Zonisamide:

  • Take zonisamide orally as prescribed by your doctor, typically 1 to 2 times per day, with or without food.
  • Drink plenty of liquids to avoid kidney stones unless instructed otherwise by your doctor.
  • The dosage is determined by your medical condition and response to treatment. Your doctor will start on a low dose and gradually increase it.
  • To get the most benefit, take it regularly at the same times each day.
  • Do not discontinue this medication abruptly; consult your doctor to taper off gradually if needed.
