The medication treatment of hyperthyroidism mainly includes antithyroid drugs such as methimazole and propylthiouracil, and the time of stopping the medication varies according to the therapeutic effect. Antithyroid medication in our clinic is mainly used to treat hyperthyroidism with methimazole and propylthiouracil, which are divided into the treatment period and maintenance period. It takes about 4 to 8 weeks to control symptoms during the treatment period of hyperthyroidism, and when the serum thyroid hormone reaches normal, the dosage is reduced and the drug is discontinued after 12 to 18 months of maintenance, and the best indicator for discontinuation of the drug is a normal thyroid function and a negative TRAb. It is recommended that patients with hyperthyroidism take the medication as prescribed by the doctor, under the guidance of the doctor, do not take the medication on their own and change the dosage arbitrarily.
