Tegretol, the generic name for carbamazepine, is an anti-epileptic and manic-depressive prescription medication. The drug may also be prescribed for facial nerve pain. It is taken orally in tablet or liquid form. Although rare, some patients have experienced severe allergic reactions to the medication. If you are considering taking Tegretol, consult a physician.
How It Works
Tegretol is an anticonvulsant that targets over-active electrical activity in the brain. According to Novartis, the pharmaceutical company that distributes the drug, the exact mechanisms for its anti-epileptic and pain-relieving properties are not completely clear. In clinical trials, the drug was shown to reduce seizures by decreasing specific nerve responses.
Uses
Tegretol is primarily used to treat seizures but it can also be used to treat facial nerve pain. In people with manic-depression, the drug combats the symptoms of mania, a condition in which mood is abnormally elevated. It also works in patients suffering from both mania and depression. According to the National Library of Medicine, Tegretol may also be used to treat drug withdrawal symptoms, stress disorders and some pain syndromes.
Precautions
Certain people should be wary of taking Tegretol. Before beginning treatment, patients should discuss the pros and cons. For example, the Mayo Clinic cautions that individuals with allergies to foods, dyes, preservatives and other medications may also have an adverse reaction to Tegretol. The National Library of Medicine further warns that Tegretol can cause a severe allergic reaction called Stevens-Johnson syndrome that can damage the skin and internal organs. In addition, older patients may experience harsher side effects. Women who are pregnant or breast feeding may be putting their infant at risk. Some medical conditions may make a patient more susceptible to side effects. These include heart disease and anemia.
Side Effects
Side effects vary. The Mayo Clinic lists as common side effects clumsiness, nausea and mild drowsiness. Some side effects can be severe and may require medical attention. Common severe side effects include changes in vision such as double or blurred vision. Symptoms of an overdose of Tegretol could include spasms, irregular heartbeat and severe drowsiness. If you experience any of these side effects, or if side effects worsen, contact a doctor immediately.
Proper Use
Depending on the form of carbamazepine taken, different instructions apply. Oral tablets are best taken with meals. Grapefruit or grapefruit juice can impair the body's ability to get rid of Tegretol, resulting in a higher concentration of the medicine in the body. For this reason, grapefruit should be avoided during treatment. Each patient is given a specific dosage and dosing regimen. If a dose is missed, take another as soon as remembered unless the next scheduled dose is near. Physician directions regarding use of Tegretol should always be closely followed.
