If hyperthyroidism still occurs after completing a course of medication, iodine-131 treatment or thyroidectomy may be considered as an option. Patients not in remission on tabazol therapy may be considered for longer term low dose therapy; 6. Definition of remission of hyperthyroidism: TSH, FT4 and T3 remain normal for up to 1 year after termination of drug therapy. The remission rate is about 20-40%.

The main adverse reactions of anti-hyperthyroid drugs are as follows: 1. Granulocytopenia: It causes leukopenia with an incidence of about 10%. It occurs mainly within 2-3 months after the start of treatment and should be discontinued when peripheral blood leukocytes are below 3×109/L or neutrophils are below 1.5×109/L. However, care should be taken to distinguish whether the leukopenia is due to hyperthyroidism itself or to medication. It is necessary to check leukocytes weekly before and after treatment. 2. Skin rash: The incidence is about 2% to 3%. Antihistamines can be tried first. When the rash is serious, the drug should be stopped in time to avoid exfoliative dermatitis. 3, cholestatic xanthogranuloma, angioneurotic edema, toxic hepatitis, acute arthralgia and other adverse reactions are relatively rare, such as the occurrence of immediate discontinuation of the drug. 4.Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis can involve multiple organs throughout the body such as lungs, kidneys, joints, etc., resulting in dysfunction of the corresponding organ tissues. For example, renal failure.
