After more than 3 years of treatment, the child’s condition is stable from the current situation and the maintenance treatment has been more than 2 years, so you can consider the issue of stopping the medication. The following are my comments for your reference: 1. The recurrence rate of hyperthyroidism in children after stopping medication is higher than that of adults. The information you provided does not describe the size of the child’s thyroid gland. Generally speaking, the relapse rate is lower in children with a significantly smaller thyroid gland and negative TSAb (thyroid stimulating antibody) or TRAb (TSH receptor antibody) after drug treatment, while the relapse rate is higher in children with a larger thyroid gland or positive TRAb or TSAb at the time of drug discontinuation. 2. Thyroxine tablets do not improve the rate of remission of hyperthyroidism and can be discontinued at this stage. Tabazol can be reduced until discontinued according to your regimen. Most recurrences of hyperthyroidism occur within 3 to 6 months after discontinuation, so it is important to monitor thyroid function at this stage. 3. Thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) can be increased in patients with hyperthyroid Graves’ disease and represent the presence of an autoimmune response in the thyroid gland. The antibodies that have an effect on drug withdrawal are TRAb and TSAb mentioned above (TSAb is a component of TRAb and is more difficult to measure, so sometimes TRAb can be used to represent TSAb), and can be measured before drug withdrawal if possible.
