The generic name of Euthyrox is Levothyroxine Tablets, which are to be taken on the day of review in the first month after total thyroidectomy. The thyroid gland is the organ that secretes thyroid hormones, which play an important role in the normal metabolism of various organs and tissues in the human body. After total thyroidectomy, the lack of thyroid hormone in the body will lead to abnormal metabolism, so you need to take levothyroxine tablets for thyroid hormone replacement therapy. After the operation, the drug usually needs to be taken regularly, and regular rechecks are required to adjust the dosage of the drug in time according to the condition of the thyroid function, so that the thyroid hormone in the body can reach the normal level. Therefore, it is also necessary to take levothyroxine tablets on the day of the first month’s review according to the doctor’s prescription in order to reflect the true level of thyroid hormones, so that the doctor can easily adjust the medication. Levothyroxine tablets generally have no significant adverse effects when taken in the right amount, but may have adverse effects such as tachycardia and angina pectoris when taken in the wrong dosage. Levothyroxine Tablets are contraindicated in those who are allergic to Levothyroxine Tablets and its excipients, untreated hypoadrenalism, pituitary insufficiency and thyrotoxicosis, acute myocardial infarction, acute myocarditis, acute total carditis, and women during pregnancy. Note that levothyroxine tablets are not used in combination with antithyroid drugs to treat hyperthyroidism.
