Your doctor may want you to have a number of blood tests before you are treated with Carbamazepine and sometimes during your treatment. This is quite usual and nothing to worry about.
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.
If you experience any of the below signs and symptoms suggestive of allergic reactions, stop taking carbamazepine and contact your doctor immediately:
- Immediate allergic reactions such as skin rash, itching, hives and swelling, sometimes of the face and mouth (angioedema). These allergic reactions may be severe (anaphylaxis).
- Serious skin rashes (Stevens-Johnson syndrome, toxic epidermal necrolysis). 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. - In very rare cases, patients of Japanese descendance can develop a very fast progressing form of diabetes (fulminant type 1 diabetes), usually in association with an allergic skin reaction. This disease can be fatal within 24 hours. If you have a rash, plausibly related to carbamazepine use and you experience symptoms like increased thirst and hunger, frequent need to urinate, nausea and vomiting, stomach pain, weakness or fatigue, shortness of breath, fruity-scented breath, and confusion, immediately seek medical attention.
Some people may have a reduced response to carbamazepine treatment, if they bear a specific genetic variant of a transporter protein (ABCB1 transporter). If carbamazepine is not working as expected and your disease is not adequately controlled, your doctor may decide to test you for the presence of this specific gene and adjust the treatment.
If you experience dizziness, drowsiness, decrease in blood pressure, confusion, due to carbamazepine treatment, this may lead to falls.
You should also ask yourself these questions before you use Carbamazepine Essential Pharma Suppositories. If the answer to any of these questions is YES, discuss your treatment with your doctor or pharmacist because Carbamazepine Essential Pharma Suppositories might not be the right medicine for you.
- Are you pregnant or planning to become pregnant?
- Are you breast-feeding?
- Do you suffer from the sort of epilepsy where you get mixed seizures which include absences?
- Do you have any mental illness?
- Are you allergic to an epilepsy medicine called phenytoin, primidone or phenobarbital?
- Do you have liver problems?
- Do you have kidney problems associated with low sodium blood level or do you have kidney problems and you are taking certain medicines that lower sodium blood levels (diuretics such as hydrochlorothiazide, furosemide)?
- Are you elderly?
- Do you have any eye problems such as glaucoma (increased pressure in the eye) or do you have difficulty retaining your urine?
There is a risk of harm to the unborn child if Carbamazepine Essential Pharma is used during pregnancy. Women of childbearing age should use effective contraception during treatment with Carbamazepine Essential Pharma and for at least two weeks after the last dose (see Pregnancy and breast-feeding).
It is important to tell your doctor or pharmacist if you are taking any other medicines for epilepsy at the same time as carbamazepine and you are pregnant, think you may be pregnant, or are planning to have a baby (see also the information in Section 2 on pregnancy and breast-feeding).
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
If you are a woman who is able to have a baby and are not planning a pregnancy, you should use effective contraception during treatment with Carbamazepine Essential Pharma. Carbamazepine Essential Pharma may affect how hormonal contraceptives, such as the contraceptive (birth control) pill, work and make them less effective at preventing pregnancy. Talk to your doctor, who will discuss with you the most suitable type of contraception to use while you are taking Carbamazepine Essential Pharma. If treatment with Carbamazepine Essential Pharma is discontinued you should continue using effective contraception for at least two more weeks following discontinuation.
If you are pregnant, or think you may be pregnant, you must tell your doctor straight away and discuss possible risks the epilepsy medicine you are taking might pose to your unborn baby.
If you are planning to become pregnant you should discuss your epilepsy treatment with your doctor as early as possible before you become pregnant.
You should not stop your treatment without discussing this with your doctor. Suddenly stopping may lead to breakthrough seizures which may harm you and your unborn baby. It is important that your epilepsy remains well controlled.
Taking carbamazepine during pregnancy increases the chance that the baby may have a physical birth abnormality (major congenital malformations). Studies with women treated with carbamazepine for epilepsy have shown that on average 4-5 babies in every 100 will have serious physical birth abnormalities. This is compared with 2 to 3 babies in every 100 born to women who do not have epilepsy.
These abnormalities can develop early in pregnancy, even before you know you are pregnant. The most common types of major congenital malformations reported for carbamazepine include spina bifida (where the bones of the spine are not properly developed); facial and skull malformations including cleft lip/palate; skeletal, heart, urinary tract and sexual organ malformations.
Studies have found that the risk of physical birth abnormalities increases with increasing doses of carbamazepine. Therefore, it is important that where possible you are prescribed the lowest dose to control your epilepsy.
Problems with neurodevelopment (development of the brain) have been reported in babies born to mothers who used carbamazepine during pregnancy. Some studies have shown that carbamazepine negatively affects neurodevelopment of children exposed to carbamazepine in the womb, while other studies have not found such an effect. The possibility of an effect on neurodevelopment cannot be ruled out.
Ask your doctor about taking folic acid when trying for a baby and during pregnancy. Folic acid may lower the general risk of serious physical birth abnormalities that exists with all pregnancies.
Taking more than one epilepsy medicine at the same time may also increase the risk of physical birth abnormalities. This means that where possible, your doctor should consider using one epilepsy medicine to control your epilepsy.
Studies suggest that taking carbamazepine during pregnancy does not increase the risk the child may have difficulties with learning and thinking ability.
If you take Carbamazepine Essential Pharma Suppositories during pregnancy, your baby is also at risk for bleeding problems right after birth. Your doctor may give you and your baby a medicine to prevent this.
Breast-feeding
Mothers being treated with Carbamazepine Essential Pharma Suppositories can breastfeed their babies, but you must tell the doctor as soon as possible if you think that the baby is suffering side effects such as excessive sleepiness, skin reaction or yellow skin and eyes, dark urine or pale stools.
Fertility (Women of childbearing potential)
You should use an effective method of contraception throughout your treatment with Carbamazepine Essential Pharma Suppositories and for a period of 28 days, after discontinuation of treatment. Irregularity of the menstrual period may occur in women taking hormonal contraceptives (birth control medicines) and Carbamazepine Essential Pharma Suppositories. The hormonal contraceptive may become less effective and you should consider using a different or additional non-hormonal contraceptive method. Ask your doctor about effective contraception.
