Uses for carbamazepine

Carbamazepine injection is used as a substitute for oral carbamazepine to treat adults with specific types of seizures (epilepsy). Carbamazepine acts in the brain and nervous system to manage seizures. This medicine is an anticonvulsant.

This medicine is to be given only by or under the direct supervision of your doctor.

Precautions while using carbamazepine

It is very important for your doctor to monitor your progress closely while you are taking this medicine. Your doctor may want you to have certain tests to check if you are getting the right amount of medicine or if you are experiencing side effects without knowing. Additionally, the dose of this medicine may need to be adjusted frequently.

Using this medicine during pregnancy can harm your unborn baby. Use an effective form of birth control to prevent pregnancy. If you think you might be pregnant while taking this medicine, inform your doctor immediately.

Do not use carbamazepine with a monoamine oxidase inhibitor (MAOI) or within the first 14 days after stopping a MAOI. MAOIs are used for depression, and some examples include isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), or tranylcypromine (Parnate®). Do not take this medicine with boceprevir (Victrelis®), delavirdine (Rescriptor®), and nefazodone (Serzone®).

Serious skin reactions can happen with this medicine. Contact your doctor right away if you experience blistering, peeling, or loose skin, red skin lesions, severe acne or skin rash, sores or ulcers on the skin, a fever, or chills while taking this medicine.

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 the skin. These may be signs of a serious blood problem.

Carbamazepine may cause serious allergic reactions that affect multiple organs (like the liver or kidneys). Contact your doctor right away if you have a fever, dark urine, headache, rash, stomach pain, unusual tiredness, or yellow eyes or skin.

Carbamazepine may make some people feel agitated, irritable, or show other unusual behaviors. It may also cause some people to have suicidal thoughts or to feel more depressed. If you or your caregiver notice any of these side effects, tell your doctor immediately.

This medicine will enhance the effects of alcohol and other CNS depressants (medicines that induce drowsiness). Some examples of CNS depressants include antihistamines or medicines for hay fever, allergies, or colds, sedatives, tranquilizers, sleeping medicines, prescription pain medications or narcotics, medicines for seizures (like barbiturates), muscle relaxants, and anesthetics, including some dental anesthetics. Talk to your doctor before taking any of these while 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. Make sure you understand how this medicine affects you before driving, operating machinery, or doing anything else that could be dangerous if you are not alert or coordinated.

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

Do not stop taking this medicine without first consulting your doctor. Your doctor may want you to gradually decrease your 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 using carbamazepine. Unplanned pregnancies could occur. Use a different or additional form of birth control while taking carbamazepine. If you have questions about this, consult your doctor.

Grapefruit and grapefruit juice may increase the effects of this medicine by raising the levels in your body. You should not eat grapefruit or drink grapefruit juice while taking this medicine.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or over-the-counter (OTC) medicines, as well as herbal or vitamin supplements.

Before using carbamazepine

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

Allergies

Inform your physician if you have ever had any unusual or allergic reaction to this medicine or any other drugs. As well 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 have not been performed on the relationship of age to the effects of carbamazepine injection in the pediatric population. Safety and efficacy have not been established.

Geriatric

Although appropriate studies on the relationship of age to the effects of carbamazepine injection have not been performed in the geriatric population, geriatric-specific issues are not expected to limit the usefulness of carbamazepine injection in the elderly. Nevertheless, elderly patients are more likely to have hyponatremia, which may require caution.

Breast Feeding

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