Carbatrol : Uses, Side Effects, Interactions & More

IMPORTANT WARNING:

Carbatrol (Carbamazepine) can cause life-threatening allergic reactions called Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). These allergic reactions can cause serious damage to the skin and internal organs. The risk of SJS or TEN is higher in people of Asian descent who have a genetic (inherited) risk factor. If you are Asian, your doctor will usually order a test to see if you have the genetic risk factor before prescribing Carbatrol. If you do not have this genetic risk factor, your doctor may prescribe Carbatrol, but there is still a slight risk that you will develop SJS or TEN. Call your doctor right away if you develop a painful rash, hives, blistering or peeling of the skin, easy bruising, mouth sores, or fever during your treatment with Carbatrol. Stevens-Johnson syndrome or toxic epidermal necrolysis usually occurs during the first months of treatment with Carbatrol.

Carbatrol can lower the number of blood cells made by your body. In rare cases, the number of blood cells can decrease enough to cause serious or life-threatening health problems.

If you experience any of the following symptoms, call your doctor immediately: sore throat, fever, chills, or other signs of infection that come and go or do not go away; difficulty breathing; fatigue; unusual bleeding or bruising, such as heavy menstrual bleeding, a nosebleed, or bleeding gums; small red or purple spots or spots on the skin; or mouth sores ..
