How Much Does Synthroid Cost

Generically known as levothyroxine, Synthroid is a medicine tablet that is used to treat Hashimoto’s disease and hypothyroidism. Its active ingredient is the levothyroxine sodium, which is identical with thyroxine, a hormone naturally produced by the thyroid gland. The medication works effectively if taken on a regular basis as prescribed by the doctor. Moreover, Synthroid is not for patients with hyperthyroidism, and it should not be taken for losing weight.
