Muscle Relaxant - Atretol (Brand name: tegretol)

INDICATIONS

Tegretol (carbamazepine) is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and pain.
Tegretol is used to treat seizures and nerve pain such as trigeminal neuralgia and diabetic neuropathy. Carbamazepine is also used to treat bipolar disorder.
Tegretol may also be used for purposes not listed in this medication guide.

INSTRUCTIONS  

Take Tegretol exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results.

Do not crush, chew, or break an extended-release Tegretol tablet. Swallow the pill whole. Breaking the pill would cause too much of the drug to be released at one time.

Shake the Tegretol oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

It may take up to 4 weeks before your symptoms improve. Keep using the medication as directed and call your doctor promptly if this medicine seems to stop working as well in preventing your seizures. Tegretol can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill.

To be sure Tegretol is not causing harmful effects, your blood cells and kidney function may need to be tested often. Do not miss any follow up visits to your doctor for blood or urine tests. Your doctor may also recommend having your eyes checked regularly while you are taking this medicine.

Do not stop using Tegretol without first talking to your doctor, even if you feel fine. You may have increased seizures or unpleasant withdrawal symptoms if you stop using this medicine suddenly. Wear a medical alert tag or carry an ID card stating that you take Tegretol. Any medical care provider who treats you should know that you take seizure medication.

STORAGE
