1) What Carbimazole is and what it is used for
Carbimazole belongs to a group of medicines called anti-thyroid medicine.
Carbimazole is used for adults and children with an over-active thyroid gland
(called 'hyper-thyroidism')
• It works by reducing the amount of thyroid hormones made in your
thyroid gland
• It can be used on its own, or with other treatments for an over-active
thyroid gland
• It can also be used before part of the thyroid gland has been removed by
surgery. It helps the thyroid gland work properly before the surgery.

2) What you need to know before you take Carbimazole
Do not take Carbimazole if:
• You are allergic (hypersensitive) to carbimazole or any of the ingredients
of Carbimazole tablets (listed in Section 6)
• You are allergic (hypersensitive) to other anti-thyroid medicines such as
thiamazole, methimazole or propylthiouracil
• You are breast-feeding.
• You have a severe liver disorder
• You have a serious blood disorder.
Do not take Carbimazole tablets if any of the above apply to you. If you are
not sure, talk to your doctor or pharmacist before taking Carbimazole.

If you are not sure if the above applies to you, talk to your doctor or

Children
Do not give this medicine to children under the age of two years because it
may not be safe or effective.
Other medicines and Carbimazole
Please tell your doctor or pharmacist if you are taking or have recently taken
any other medicines.
This includes medicines obtained without a prescription, including herbal
medicines. This is because Carbimazole can affect the way some medicines
work. Also some medicines can affect the way Carbimazole works.
In particular tell your doctor or pharmacist if you are taking any of the
following:
• Medicines to thin your blood or to stop clotting
• A medicine to help your breathing called 'theophylline'
• Steroids such as prednisolone
• An antibiotic called erythromycin
• A medicine for heart failure called digitalis
• Medicines for high blood pressure called beta-blockers.
If any of the above apply to you (or you are not sure), talk to your doctor or
pharmacist before taking Carbimazole.
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. This is because there is a very small chance that your
baby may be affected.
In some cases, your doctor may prescribe Carbimazole while you are
pregnant. He or she will talk to you about this. If they do, they will lower the
possibility of any effects on your baby by:
• Using the lowest possible dose
• Stopping treatment three to four weeks before you are due to give birth.
Do not breast-feed if you are taking Carbimazole. This is because small
amounts may pass into the mother's milk.
Driving and using machines
You can drive when taking Carbimazole, but do not drive until you know how
it affects you.
Carbimazole tablets contain lactose
If you have been told by your doctor that you cannot tolerate or digest some
sugars (have an intolerance to some sugars), talk to your doctor before taking
this medicine.

You may need to keep taking Carbimazole for several months to keep control
of your thyroid gland. Your doctor will decide when treatment can be stopped.

treatment is working.
Your doctor may decide to add an additional tablet (l-thyroxine), to help
control your condition.

need radio-iodine treatment your doctor will tell you to stop taking
Carbimazole tablets for a while.
