Patient leaflet - CARBAMAZEPINE MEDREICH 400 MG TABLETS
1. What Carbamazepine Tablets are and what they are used for
Carbamazepine, the active ingredient in Carbamazepine Tablets, can affect the body in several different ways. It is an anti-convulsant medicine (prevents fits), it can also modify some types of pain and can control mood disorders.
Carbamazepine is used:
- To treat some forms of epilepsy
- To treat a painful condition of the face called trigeminal neuralgia
- To help control serious mood disorders when some other medicines don’t work.
12. What you need to know before you take Carbamazepine Tablets
If you are allergic to carbamazepine or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include swelling of the face or mouth (angioedema), breathing problems, runny nose, skin rash, blistering or peeling.- If you are allergic to similar kind of drugs as carbamazepine such as oxcarbazepine (Trileptal), or to any of a related group of drugs known as tricyclic antidepressants (such as amitriptyline or imipramine). If you are allergic to carbamazepine there is a one in four (25%) chance that you could also have an allergic reaction to oxcarbazepine.
- If you have any heart problems.
- If you have ever had problems with your bone marrow.
- If you have a blood disorder called porphyria.
- If you have taken drugs called monoamine oxidase inhibitors (MAOIs), used to treat depression, within the last 14 days.
A small number of people being treated with anti-epileptics such as carbamazepine have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Serious skin rashes (Stevens- Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of carbamazepine. Frequently, the rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes are often preceded by influenza-like symptoms fever, headache, body ache (flu-like symptoms). The rash may progress to widespread blistering and peeling of the skin. The highest risk for occurrence of serious skin reactions is within the first months of treatment.
These serious skin reactions can be more common in people from some Asian countries. The risk of these reactions in patients of Han Chinese or Thai origin may be predicted by testing a blood sample of these patients. Your doctor should be able to advise if a blood test is necessary before taking carbamazepine.
If you develop a rash or these skin symptoms, stop taking carbamazepine and contact your doctor immediately.

1. What Carbamazepine Tablets are and what they are used for
Carbamazepine, the active ingredient in Carbamazepine Tablets, can affect the body in several different ways. It is an anti-convulsant medicine (prevents fits), it can also modify some types of pain and can control mood disorders.
Carbamazepine is used:
- To treat some forms of epilepsy
- To treat a painful condition of the face called trigeminal neuralgia
- To help control serious mood disorders when some other medicines don’t work.
- If you are allergic to carbamazepine or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include swelling of the face or mouth (angioedema), breathing problems, runny nose, skin rash, blistering or peeling.
- If you are allergic to similar kind of drugs as carbamazepine such as oxcarbazepine (Trileptal), or to any of a related group of drugs known as tricyclic antidepressants (such as amitriptyline or imipramine). If you are allergic to carbamazepine there is a one in four (25%) chance that you could also have an allergic reaction to oxcarbazepine.
- If you have any heart problems.
- If you have ever had problems with your bone marrow.
- If you have a blood disorder called porphyria.
- If you have taken drugs called monoamine oxidase inhibitors (MAOIs), used to treat depression, within the last 14 days.
A small number of people being treated with anti-epileptics such as carbamazepine have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Serious skin rashes (Stevens- Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of carbamazepine. Frequently, the rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes are often preceded by influenza-like symptoms fever, headache, body ache (flu-like symptoms). The rash may progress to widespread blistering and peeling of the skin. The highest risk for occurrence of serious skin reactions is within the first months of treatment.
These serious skin reactions can be more common in people from some Asian countries. The risk of these reactions in patients of Han Chinese or Thai origin may be predicted by testing a blood sample of these patients. Your doctor should be able to advise if a blood test is necessary before taking carbamazepine.
If you develop a rash or these skin symptoms, stop taking carbamazepine and contact your doctor immediately.
