Carbimazole (CMZ) is a medication used to treat overactive thyroid, including Grave's disease.[3] In the United Kingdom, it is the first choice antithyroid medicine.[3] It can take a month or two before full effects.[3] It is taken by mouth.[3]
Side effects may include fever, rash, and joint pain.[2] Rare side effects may include bone marrow problems resulting in low white blood cells.[3] Other side effects may include pancreatitis.[3] Use during pregnancy may harm the baby; though, it has been used in pregnancy due to there also being harms of high thyroid.[3][2]
It is a type of thioamide, along with propylthiouracil (PTU).[4][2] After absorption it is converted to the active form, methimazole.[2] Methimazole prevents the thyroid peroxidase enzyme from adding iodine and coupling the tyrosine residues on thyroglobulin, hence reducing the production of T3 and T4.[4]
Carbimazole came into medical use in 1952.[5] It is on the World Health Organization's List of Essential Medicines as an alternative to methimazole.[6] It is available as a generic medication.[3] In the United Kingdom three month at a dose of 20 mg per day costs the NHS about £6 as of 2023.[3]
