What should I watch for while taking carbamazepine?
Visit your prescriber or health care professional for a regular check on your progress. Report any unusual side effects to your prescriber promptly.
Do not change brands or dosage forms of carbamazepine without discussing the change with your prescriber or healthcare professional.
If you are taking carbamazepine for epilepsy (seizures) do not stop taking it suddenly. This increases the risk of seizures. Wear a Medic Alert bracelet or necklace. Carry an identification card with information about your condition, medications, and prescriber or health care professional.
Carbamazepine is available by many different branded names, such as Carbatrol®, Epitol®, Equetro., or Tegretol®. The different brands may be used for different illnesses, such as seizures or manic-depression. You should not take more than one brand name of carbamazepine at one time. If you do so, you could become seriously ill. If you are not sure if you are taking more than one brand, ask for health care provider immediately.
You may get drowsy, dizzy, or have blurred vision. Do not drive, use machinery, or do anything that needs mental alertness until you know how carbamazepine affects you. To reduce dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can increase drowsiness and dizziness. Avoid alcoholic drinks.
If you are female and are taking birth control pills (contraceptive pills) or other hormonal birth control methods (like injections), you should know that the birth control may not work as well while you are taking carbamazepine. You may need to talk to your prescriber about effective ways to prevent pregnancy. Let your prescriber know if you experience any unusual menstrual-type bleeding or spotting or if you think you might be pregnant while on this medicine.
Carbamazepine may make your skin more sensitive to the sun or ultraviolet light. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen (at least SPF 15). Do not use sun lamps or sun tanning beds or booths.
If you are going to have surgery, tell your prescriber or health care professional that you are taking carbamazepine.
