    What is Zonegran used for?

    Zonegran (zonisamide) is a sulfa drug prescribed to help prevent partial seizures. Zonegran gets used in combination with other anti-convulsant medications to treat partial seizures for adults with epilepsy. 

    Zonegran capsules contain zonisamide. This is a medication that is commonly used to treat epilepsy. It works to stabilize electrical activity in the brain.

    Zonegran prevents epileptic fits by stopping the excessive electrical activity in the brain. It’s not fully understood exactly how this medication works. It is thought to act on calcium and sodium channels on the nerve cells in the brain. Sodium has to move into the nerve cells in order for an electrical signal to build up and then get passed on to the other nerve cells. Zonegran might prevent sodium from entering the nerve cells when they start firing abnormally repetitive and rapid electrical signals. This helps stabilise electrical brain activity and prevents the excessive signals that cause seizures from spreading throughout the brain.

    How to Use Zonegran?

    Always take Zonegran exactly as your doctor prescribes it. Follow the directions on your prescription label. Don’t take Zonegran in any way other than what your doctor has instructed. 

    Take Zonegran with a full glass of water. You should drink 6-8 glasses of water per day to prevent kidney stones while under treatment with Zonegran. 

    You can take Zonegran with or without food. Ensure you always swallow the capsule whole, do not break, chew, open, or crush it. You may need frequent blood tests while on Zonegran. 

    If you have to get surgery, inform the surgeon you are taking Zonegran in advance as you may have to stop taking this medication for a short time. 

    Do not stop Zonegran abruptly, even if you feel fine. Stopping suddenly can cause an increase in seizures. Your doctor will help you taper your dose. 

    Seizures often get treated with a combination of drugs. Use all the medications as directed by your doctor and read the instructions or medications guides you’re given.
