Zeptol CR 400 mg Tablet

Zeptol CR 400 mg Tablet is a controlled-release tablet that contains 400 mg of carbamazepine in each tablet. It belongs to the anti-convulsant medicine class and is used to help control certain types of seizures. Zeptol CR 400 mg Tablet is also prescribed for some nerve pain conditions and, in some patients, bipolar disorder when a doctor thinks it is appropriate. Because it is a controlled-release tablet, it is designed to release medicine gradually rather than all at once.

How it works: Carbamazepine helps calm overactive nerves in the brain by reducing the rapid electrical signals that can trigger seizures. In Zeptol CR 400 mg Tablet, the controlled-release tablet form releases carbamazepine slowly so the medicine works more evenly over time.

Zeptol CR 400 mg Tablet is a higher-strength option than Zeptol CR 200 mg Tablet, so it may suit people who have already been titrated upward and need a larger single dose. This strength is not usually the first dose for everyone; a doctor may choose Zeptol CR 400 mg Tablet when a higher maintenance dose or fewer tablets per day is needed. The controlled-release tablet may also help provide steadier carbamazepine levels across the day.
