There are two types of hyperthyroidism medications, methimazole and prothiouracil, and their side effects mainly include neutropenia, allergic reactions, vasculitis, liver damage, and gastrointestinal system symptoms.
Methimazole: The side effects of methimazole mainly include neutropenia, which leads to the inability of the immune system to resist bacterial invasion, and is prone to serious infections, as well as allergic reactions such as hives, liver damage, gastrointestinal dysfunction, and so on.
Propylthiouracil: The side effects of propylthiouracil are mainly neutropenia and ANCA-associated vasculitis, which may result in hemoptysis and hematuria, as well as gastrointestinal dysfunction, leading to nausea and vomiting.
If the side effects of hyperthyroidism occur, the drug should be discontinued, and the treatment should be carried out under the guidance of the doctor and the next step in the treatment.
