Recommended dose:

Adults:The initial normal dose is20 to 60 mg of carbimazol per day orally (4 to 12 Neo-tomizol tablets) depending on the degree of hyperthyroidism, divided into 2-3 doses per day. The initial treatment should be established until the patient's thyroid function normalizes.

Maintenance regimen:

The maintenance dose is usually5 to 15 mg of carbimazol (1 to 3 Neo-tomizol tablets) per day. Treatment should continue normally between 6 and 18 months.

It is recommended to perform analytical controls of thyroid function and adjust the dose as necessary to maintain normal levels of thyroid hormones.

Block and replacement regimen:

The dose is maintained at the initial level of 20 to 60 mg of carbimazol per day orally (4 to 12 Neo-tomizol tablets). L-thyroxine 50-150 mg per day is administered concurrently to prevent hypothyroidism. Treatment should continue between 6 and 18 months.

Children and Adolescents (3 to 17 years old):

The initial normal dose is0.75 – 1 mg/kg/day divided into two equal doses and administered every 8 hours, and adjusted according to thyroid hormone levels. The maintenance dose will be half (50%) of the initial dose (0.4 – 0.5 mg/kg/day).
