The medications used in the treatment of hyperthyroidism are not hormones. The medications used in hyperthyroidism are mainly called anti-thyroid drugs. These are drugs that inhibit the activity of enzymes related to the thyroid gland, and by inhibiting the activity of the enzymes, they have the effect of suppressing the secretion of thyroid hormones. Therefore, this class of drugs does not belong to the hormone class, much less the conventional sense of glucocorticoids. The drugs for hyperthyroidism do not produce adverse reactions such as corresponding obesity, but still have certain related side effects and adverse reactions, mainly in the form of possible leukopenia, liver function damage and skin rash. Therefore, it is necessary to pay attention to the regular review of blood count and liver function, and to observe the appearance of skin rash after using the drug, so as to reduce or avoid the side effects of the drug and to achieve better treatment of hyperthyroidism.
