Neomercazole 5 mg contains the active ingredient Carbimazole, which belongs to the group of medicines known as anti-thyroid agents. It is used to reduce the formation of thyroid hormones in adults and children with an overactive thyroid gland. The condition is often referred to as hyperthyroidism. Neomercazole can also be used in more serious cases, for example, to restore normal function of the thyroid before its partial removal by surgery. 

This medicine may also be used in combination with other treatments for hyperthyroidism.

Always take Neomercazole exactly as your doctor has told you. In case of any confusion, please check with your doctor. The tablet should be taken orally with a glass full of water. You can take the tablet before, after, or during meals. The total number of daily tablets you take may be divided into two dosage intervals (morning and evening) or three intervals (morning, afternoon, and night).   The recommended starting dose for adults is four to twelve 5 mg tablets daily. Once control is achieved, your doctor will gradually reduce your dose to one to three 5 mg daily. For children, the recommended starting dose is three 5 mg tablets daily. The dosage will be decided by your doctor as per the individual needs and may be changed at intervals during treatment. Do not make any changes to your dosing regimen without consulting your doctor first. Your doctor may add a tablet to help control your condition. Some improvement is usually felt within one to three weeks. However, the full effects usually take four to eight weeks. To maintain control of the thyroid gland, you may need to take Neomercazole tablets for several months. Your doctor will advise you about when to stop the treatment. Your doctor may conduct blood tests to help determine how you are responding to the treatment.
