Overview
Tegretol 200mg Tablet contains carbamazepine 200mg, an anticonvulsant and mood-stabilising medicine. It is used to control certain types of epileptic seizures, to relieve the severe nerve pain of trigeminal neuralgia, and to prevent mood episodes in bipolar disorder. Because it has a narrow safety margin and needs regular blood monitoring, it is only used under specialist supervision.
Carbamazepine works by blocking voltage-gated sodium channels in overactive nerve cells, which stabilises the nerve membrane and reduces the repetitive, uncontrolled electrical firing that causes seizures and nerve pain.
How it Works
Carbamazepine binds to sodium channels in their inactive state, prolonging the time before they can fire again. This reduces the high-frequency repetitive nerve signalling seen in seizures and in trigeminal neuralgia, without normally suppressing single, necessary nerve impulses.
Directions for Use
Take Tegretol 200mg Tablet with food to reduce stomach upset, and try to take it at the same times every day, since consistent blood levels are important for seizure control. Swallow the tablet whole unless your doctor has told you it can be halved. Do not stop taking this medicine suddenly without medical advice, as this can trigger seizures.
Dosage
Tegretol 200mg Tablet dosing is highly individualised: your specialist usually starts at a low dose and increases it gradually while monitoring blood carbamazepine levels, seizure/pain control, and side effects. Never adjust your own dose – even a small change can affect seizure control or cause toxicity, because carbamazepine has a narrow therapeutic range.

Frequently Asked Questions
What is Tegretol 200mg Tablet used for?
Tegretol 200mg Tablet is used to control certain types of epileptic seizures, to treat the severe facial nerve pain of trigeminal neuralgia, and to help prevent mood episodes in bipolar disorder. Your specialist will confirm the specific reason it has been prescribed for you.
Why do I need regular blood tests while taking this medicine?
Carbamazepine has a narrow therapeutic range, meaning the difference between an effective dose and a toxic one is small, and it can rarely affect the liver, blood cell counts, and sodium levels. Regular blood tests let your specialist keep your dose safe and effective and catch any problem early.
Can I stop taking carbamazepine once my seizures or pain are under control?
No. Do not stop or change your dose without your specialist’s advice, as stopping suddenly can trigger seizures even if you have been seizure-free for a long time.
Does this medicine affect my birth control pills?
Yes, carbamazepine can make hormonal contraceptives (the pill, patch, or certain implants) less effective. Discuss reliable alternative or additional contraception with your doctor.
Can I drive or operate machinery while taking this medicine?
Carbamazepine can cause drowsiness and dizziness, particularly when starting treatment or after a dose increase. Avoid driving or operating machinery until you know how this medicine affects you.
