Why some doctors prescribe levothyroxine tablets to the hyperthyroidism or hypothyroidism patient?😨😨😨

Do you see the doctor do that? Do you feel confused? Let's see why the doctor do it~~

Levothyroxine

It is a thyroid medicine that can substitute hormone normally produced by the thyroid gland to regulate the body's metabolism and energy. 

So, it is easy to understand why the doctor prescribes it to the hypothyroidism patient. It will supply the patient enough material to transform into thyroxine.

But why the hyperthyroidism patient is also prescribed it?

Clinically, the hyperthyroidism patients with exophthalmos or goiter, can be given appropriate amount of levothyroxine. The purpose is to inhibit thyroid stimulating hormone (TSH). Because when the antithyroid drugs are given to treat hyperthyroidism, the patient's thyroxine will gradually decrease, the inhibition of TSH gradually weakens. The increasing TSH will aggravate exophthalmos or goiter.

In another case, some patient will have hypothyroidism when the antithyroid drugs are a little more, and they will have hyperthyroidism when the antithyroid drugs are slightly reduced. It is difficult to adjust the dosage. Using levothyroxine and antithyroid drugs can better balance the level of thyroid hormones.
