In view of the current hot summer and the shortage of hyperthyroidism treatment drugs, hyperthyroidism patients are advised to pay attention to the following matters: 1. 2. The summer heat makes it easy to suffer from gastrointestinal diseases, so it is necessary to take precautions to avoid aggravating hyperthyroidism. 3, hyperthyroidism patients like cold and aversion to heat, but need to pay attention to the use of air conditioning to moderate. 4. Recently, we found that some patients have discontinued methimazole for hyperthyroidism because they could not buy it, leading to aggravation of hyperthyroidism and even serious dangerous situations such as severe atrial fibrillation and heart failure. Therefore, it is recommended: do not discontinue allopathic drugs, such as benzoyl, betalactam, etc. Patients with mild disease try to find methimazole, if they do not get treatment for a longer period of time, they can consider switching to second-line drugs —- propylthiouracil, but pay attention to monitoring liver function and guard against possible other adverse reactions, if methimazole is available, switch back to this drug in time. In case of older hyperthyroid patients, it is recommended to consult the nuclear medicine department directly for iodine 131 treatment. For patients with more severe hyperthyroidism, they need to change to propylthiouracil or consult the Nuclear Medicine Department for iodine 131 treatment in a timely manner, remembering not to cut off the medication and let it go, which may lead to serious consequences.
