Hypothyroidism is short for hypothyroidism. Hypothyroid medication generally refers to levothyroxine preparations. In most cases, hypothyroid patients taking levothyroxine cannot stop taking the medication and need to take it for life. Some patients with hypothyroidism, such as those with drug-induced hypothyroidism, can stop taking the medication after their thyroid function has returned to normal, and the exact time to stop taking the medication depends on the individual’s condition. 1. If the destruction of thyroid tissue in patients with hypothyroidism is irreversible, such as thyroid surgery, Hashimoto’s thyroiditis and other causes of hypothyroidism, and pituitary hypothyroidism, etc., you should take levothyroxine sodium tablets as prescribed by the doctor for a long period of time to replace the treatment, and you can not arbitrarily discontinue the medication, so as not to lead to serious consequences. 2. For hypothyroidism caused by overdose of antithyroid drugs, overdose of iodine or postpartum thyroiditis, the thyroid function is often reversible, and after correction through treatment, the thyroid function can be restored to normal, and there is no need to take medication for life. Patients with hypothyroidism should be guided by their doctors and should not stop taking medication without authorization.
