Synthroid is a alternate for a hormone that is naturally generated by your thyroid gland to control the body's energy and metabolism. Levothyroxine (generic Synthroid) is given when the thyroid does not create enough its own hormone.
Levothyroxine heals hypothyroidism (low thyroid hormone). Synthroid is also used to cure or preclude goiter (enlarged thyroid gland), which can be caused by hormone imbalances, surgery, radiation treatment, or cancer.
Levothyroxine should not be used to cure obesity or some weight problems.
Since thyroid hormone happens usually in the body, almost anybody can take levothyroxine. Patient should not use this medication if you have had a heart attack, an adrenal gland problem that is not controlled by treatment, or a thyroid disorder called thyrotoxicosis.
