Overview

Zonegran 100mg Tablet contains Zonisamide 100mg and is available as a tablet. It is classified as a prescription medicine and may only be obtained with a valid prescription from a registered medical practitioner.

Only product, safety and handling information is published here. Anything beyond that is explained to you directly by your doctor or pharmacist as part of your consultation.

DoctorOnCall is a licensed online pharmacy. Orders for Zonegran 100mg Tablet are processed only after a doctor has assessed your suitability and issued a prescription, and every order is checked by a registered pharmacist before it is sent out.

Directions for Use

Take the tablet by mouth, swallowed whole with a glass of water, with or without food, at the same time(s) each day as directed by your doctor to maintain consistent blood levels.

Dosage

The dose is started low and gradually increased by the treating doctor based on individual response and tolerability, as this medicine requires careful, individualised titration and must never be adjusted or stopped without specialist advice.

Storage Instructions

Contraindications

  • Known hypersensitivity to zonisamide, other sulfonamide medicines, or any ingredient in the tablet
  • Severe kidney or liver impairment, unless specifically directed by a specialist
  • Pregnancy, unless the treating doctor determines the benefit clearly outweighs the risk, due to potential harm to the developing baby

Drug / Food Interactions

  • Other medicines that induce or inhibit liver enzymes (such as carbamazepine, phenytoin, or rifampicin) can significantly change zonisamide levels in the blood.
  • Other carbonic anhydrase inhibitors (such as topiramate or acetazolamide) may increase the risk of kidney stones and metabolic side effects when combined with zonisamide.
  • Alcohol and other sedating medicines can increase drowsiness and impair concentration when combined with zonisamide.
  • Inform your doctor of all medicines you are taking, including other anti-epileptic medicines.

Quick Tips

  • Never stop taking this medicine suddenly, as this can trigger seizures – your doctor will guide any dose changes gradually.
  • Drink plenty of water during treatment to help reduce the risk of kidney stones.
