1. What NeoMercazole is and what it is used for
NeoMercazole contains the active substance carbimazole. NeoMercazole belongs to a group of medicines called anti-thyroid agents. NeoMercazole is used to reduce the formation of thyroid hormones in adults and children with an overactive thyroid gland. The condition is called hyperthyroidism. NeoMercazole is also used in more serious cases, for example, to restore the normal function of the thyroid before its partial removal by surgery. It may also be used together with other treatments for hyperthyroidism.

Other medicines and NeoMercazole
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 NeoMercazole can affect the way some medicines work. Also, some medicines can affect the way NeoMercazole works. In particular tell your doctor or pharmacist if you are taking any of the following:
■ Theophylline used to treat asthma or breathing problems.
■ Medicines called anticoagulants, which are used to thin the blood e.g. warfarin.
■ Steroids such as prednisolone.
■ An antibiotic called erythromycin.
■ A medicine for heart failure called digitalis.

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.
Your NeoMercazole treatment is important for you and may need to be continued during pregnancy but very rarely it can cause harm to a developing foetus. However, to reduce the possibility of any effects on your baby:
■ Your doctor should prescribe the lowest dose possible.
■ Your treatment may be discontinued three to four weeks before you are due to give birth.
■ You should not breast-feed if you are using NeoMercazole. This is because small amounts may pass into the mother's milk.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
You can drive when taking NeoMercazole, but do not drive until you know how it affects you.
NeoMercazole contains lactose and sucrose.
If your doctor has told you that you have an intolerance to some sugars, contact your doctor before taking this medicine.
3. How to take NeoMercazole
Always take NeoMercazole exactly as your doctor has told you.
You should check with your doctor or pharmacist if you are not sure.
■ The tablets should be taken by mouth.
■ You can take the tablets before, after or during meals.
■ Each day's tablets may be divided into two (morning and evening) or three daily doses (morning, noon and night).
Adults and the elderly: The recommended starting dose is one to three 20mg tablets, or four to twelve 5mg tablets daily. Once control is achieved your doctor will gradually reduce your dose to one to three 5mg tablets each day.
Use in children: The recommended starting dose is three 5mg tablets daily.
The dosage will be decided by your doctor according to your individual needs, and may be changed at intervals during treatment.
Do not change the dosage without consulting your doctor first.
Your doctor may decide to add an additional tablet (l-thyroxine), to help control your condition.
Some improvement is usually felt within one to three weeks. However, full beneficial effects usually take four to eight weeks.
In order to maintain control of the thyroid gland, you may need to continue to take NeoMercazole tablets for several months. Your doctor will decide when treatment can be stopped. They may ask you to have occasional blood tests to help them to determine how you are responding to treatment.
Radioiodine is another treatment for hyperthyroidism. If you need radioiodine treatment, your doctor will tell you to stop taking NeoMercazole temporarily.
If you take more NeoMercazole than you should
If you take more NeoMercazole than you should, contact your doctor or nearest hospital emergency department immediately. Take the container and any remaining tablets with you.
If you forget to take NeoMercazole
If you forget to take NeoMercazole take the next dose as soon as you remember. If your next dose is due, take both doses together.
If you have any further questions of the use of this medicine ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, NeoMercazole can cause side effects, although not everybody gets them.
Allergic reactions
If you have an allergic reaction, stop taking NeoMercazole and see a doctor straight away. The signs may include: sudden rash, swelling or difficulty breathing.
Stop taking NeoMercazole and see a doctor straight away if you notice any of the following side effects:
■ Sore throat.
■ Mouth ulcers.
■ High temperature or fever.

NeoMercazole can sometimes cause bone marrow depression which causes a reduction in the number of blood cells and reduces the ability to fight infection.
