Carbamazepine is used to control seizures and other problems related to the nervous system.
Carbamazepine may cause some unwanted side effects. Generally, the common side effects tend to occur at the beginning of treatment. Such side effects may include:
Inform your doctor if any of the above side effects lasts more than a few days or become severe and bothersome.
If you/your child experiences excessive drowsiness and vomiting, doubled vision and unstable movement, please consult the neurologist as he/she may be too sensitive to carbamazepine, and the doctor may need to adjust the dose.
Rare but serious side effects may manifest as the following symptoms. Contact your doctor as soon as possible, if you notice any of the following:
Stevens-Johnson syndrome (SJS) is a life-threatening skin reaction that is characterized by
skin rash*, multiple mouth ulcers,
blistering rash*, fever, itching and other symptoms.SJS usually occurs within the first few months (monitor closely for the first 3 months) of treatment. Patients who have been taking carbamazepine for more than 3 months without developing skin reactions are at low risk of SJS.
*As SJS is rapidly progressing, caregivers should consult hospital healthcare professionals if patient shows first sign of rash.
It is important to note that certain groups of patients are at a higher risk of SJS after using carbamazepine. In accordance to the Health Science Authority (HSA) regulation, it is therefore compulsory for all patients who are first prescribed with carbamazepine to be tested for the specific gene. Kindly approach your neurologists or pharmacists for further information on this.
Antibiotics such as erythromycin, clarithromycin, azithromycin should not be taken with carbamazepine.
Grapefruit or grapefruit products should also be avoided while taking carbamazepine.
Check with your doctor or pharmacist if you want to give any other medicines, supplements or herbal products to your child.
If you/your child is consulting with a different doctor, inform him/her that you/your child is currently taking carbamazepine before he/she prescribes any other medication.
