neomercazole for patients
This belongs to the group of medicines known as antithyroid drugs.
An overactive thyroid gland produces too much thyroid hormone which causes a condition known as hyperthyroidism.
This can lead to symptoms such as fast or irregular heartbeat, sweating, mood swings, shaking, weight change, weakness, tiredness, intolerance of hot temperatures, worry, menstrual problems. Carbimazole is given as a medicine to correct this hormone imbalance. It may also be used together with other treatments for hyperthyroidism.
Carbimazole is also used in the preparation of patients for thyroidectomy (part or total removal of the thyroid gland) and before radioiodine treatment.
Carbimazole is available in tablet form.
It is also sometimes known as: Neo-Mercazole. You may notice the use of any of these names on the packaging of your medicine.
