Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests before and during treatment to check your body's response to carbamazepine.
Carbamazepine is used alone or in combination with other medications to treat certain types of seizures in patients with epilepsy. It is also used to treat trigeminal neuralgia, a condition that causes facial nerve pain. Carbamazepine is in a class of medications called anticonvulsants. It works by reducing abnormal excitement in the brain.
How should this medicine be used:
Carbamazepine comes as a tablet, a chewable tablet, an extended-release (long-acting) tablet, an extended-release capsule, and a suspension (liquid) to take by mouth. The regular tablet, chewable tablet, and liquid are usually taken two to four times a day with meals. The extended-release tablet is usually taken twice a day with meals. The extended-release capsule is usually taken twice a day with or without meals. To help you remember to take carbamazepine, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take carbamazepine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them. The extended-release capsules may be opened and the beads inside sprinkled over food, such as a teaspoon of applesauce or similar food. Do not crush or chew the extended-release capsules or the beads inside them.
Shake the liquid well before each use to mix the medication evenly.
Your doctor will start you on a low dose of carbamazepine and gradually increase your dose.
It may take a few weeks or longer before you feel the full benefit of carbamazepine. Continue to take carbamazepine even if you feel well. Do not stop taking carbamazepine without talking to your doctor. Stopping carbamazepine suddenly may cause your seizures to become worse. Your doctor will probably decrease your dose gradually.
