Epitol (Oral)

Carbamazepine is used to treat specific kinds of seizures (for example, partial seizures and tonic-clonic seizures) and bipolar disorder. It is also used to help relieve pain from trigeminal neuralgia (tic douloureux).

This medicine is available only with your doctor's prescription.

It is very important for your doctor to check your or your child's progress at regular visits to ensure this medicine is working properly. Blood and urine tests may be needed to monitor for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to prevent pregnancy. If you think you might be pregnant while using this medicine, tell your doctor right away.

Do not take carbamazepine with a monoamine oxidase inhibitor (MAOI) or within the first 14 days after stopping a MAOI. MAOIs are used for depression, and examples include isocarboxazid (Marplan®), phenelzine (Nardil®), procarbazine (Matulane®), selegiline (Eldepryl®), or tranylcypromine (Parnate®). Do not use this medicine with nefazodone (Serzone®) and certain medicines for HIV/AIDS (like delavirdine, efavirenz, Atripla®, Sustiva®, Rescriptor®).

If you plan to have children, talk to your doctor before using this medicine. Some men using this medicine have become infertile (unable to have children).

Carbamazepine may cause some people to feel agitated, irritable, or show other unusual behaviors. It may also lead some people to have suicidal thoughts and tendencies or to feel more depressed. If you, your child, or your caregiver notice any of these unwanted effects, tell your doctor right away.

Contact your doctor immediately if you have a fever, sore throat, rash, mouth ulcers, nosebleeds, bleeding gums, swollen glands, or small red or purple spots on your skin. These could be signs of a serious blood problem.

This medicine may cause serious skin reactions (such as Stevens-Johnson syndrome and toxic epidermal necrolysis), which can be life-threatening and need immediate medical attention. Contact your doctor right away if you or your child have blistering, peeling, or loosening of the skin, chills, cough, diarrhea, itching, joint or muscle pain, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, or unusual tiredness or weakness while using this medicine.

This medicine can cause a serious allergic reaction called drug reaction with eosinophilia and systemic symptoms (DRESS), which affects multiple body organs (such as liver or kidney). Tell your doctor right away if you have fever, dark urine, headache, rash, stomach pain, swollen, painful, or tender lymph nodes in the neck, armpit, or groin, unusual tiredness, or yellow eyes or skin.

This medicine may lead to agitation, irritability, or other unusual behaviors. It can also cause some people to have suicidal thoughts and tendencies or to feel more depressed. If you, your child, or your caregiver notice any of these side effects, tell your doctor or your child's doctor right away.

This medicine may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Inform your doctor right away if you or your child have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after using this medicine.

This medicine will enhance the effects of alcohol and other CNS depressants (medicines that make you drowsy). Some examples of CNS depressants include antihistamines or medicines for hay fever, allergies, or colds, sedatives, tranquilizers, sleeping medicine, prescription pain medicine or narcotics, medicines for seizures (like barbiturates), muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of these while you or your child are using this medicine.

This medicine may cause some people to feel drowsy, dizzy, lightheaded, or less alert than usual, especially when starting treatment or increasing the dose. It may also cause blurred or double vision, weakness, or loss of muscle control in some people. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Contact your doctor immediately if you experience blurred vision, difficulty reading, or any other changes in vision during or after treatment. Your doctor may want you to see an ophthalmologist (eye doctor).

Some people taking carbamazepine may become more sensitive to sunlight than usual. Even brief exposure to sunlight can lead to skin rash, itching, redness or other discoloration of the skin, or severe sunburn. When you start taking this medicine:

• Stay out of direct sunlight, especially between 10:00 AM and 3:00 PM, if possible.
• Wear protective clothing, including a hat, and sunglasses.
• Use a sunblock with at least SPF 15. Some patients may need a higher SPF, especially those with fair skin. If you have questions about this, check with your doctor.
• Use a sunblock lipstick with at least SPF 15 to protect your lips.
• Do not use a sunlamp or tanning bed or booth.

If you have a severe reaction to the sun, consult your doctor.

Before undergoing any medical tests, inform the medical doctor in charge that you are taking this medicine. The results of some pregnancy tests may be affected by this medicine.

Do not stop taking this medicine without first consulting your doctor. Your doctor may want you or your child to gradually reduce the dose before stopping completely. This can help prevent worsening of seizures and reduce the risk of withdrawal symptoms.

Birth control pills that contain estrogen may not work effectively if you take them while on carbamazepine. Unplanned pregnancies may occur. Use a different or additional form of birth control while taking carbamazepine. If you have questions about this, talk to your doctor.

Do not take other medicines unless your doctor has discussed them with you. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

In deciding to use a medicine, the chances of taking the medication must be weighed against the beneficial it will do. This is a decision you and your doctor will make. For this drug, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medication or any other medicines. Additionally inform your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific issues that would limit the usefulness of Equetro® extended-release capsules in children with partial seizures, generalized tonic-clonic seizures, and mixed seizure patterns. Safety and efficacy have been established.

Appropriate studies have not been performed on the relationship of age to the effects of Equetro® extended-release capsules in children with bipolar disorder and pain of trigeminal neuralgia. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of Tegretol® chewable tablets, suspension, tablets, or extended-release capsules in children with partial seizures, generalized tonic-clonic seizures, mixed seizure patterns, bipolar disorder, and pain of trigeminal neuralgia.

Geriatric

Appropriate studies on the relationship of age to the effects of carbamazepine have not been performed in the geriatric population, geriatric-specific problems are not expected to limit the usefulness of carbamazepine in the elderly. Nevertheless, elderly patients are more likely to have confusion, hyponatremia (low sodium in the blood), or agitation and age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving carbamazepine.

Breast Feeding

There are no adequate studies in women for determining infant chance when using this medicine during breastfeeding. Weigh the potential benefits against the potential chances prior to taking this medicine while breastfeeding.
