This medicine helps reduce seizures in people with epilepsy.
Typically, start with 50 mg twice a day. Your doctor will slowly increase this to a maintenance dose of 100-300 mg twice a day (when used alone) or 100-200 mg twice a day (with other medicines).
Take the tablets twice a day, about 12 hours apart. Swallow them whole with water, with or without food. Try to take them at roughly the same time each day.
The maximum daily dose is usually 600 mg.
Suitable for older adults, with specific precautions. Reduce the dose in severe renal impairment. Common adverse effects include dizziness and nausea. (updated 6.10.2025)
