what is the active ingredient in the prescription drug synthroid?

Answer 1

Levothyroxine:It is a synthetic thyroid hormone used as a thyroid hormone replacement drug (brand names include Eltroxin, Levothroid, Levoxine, Levoxyl, Synthroid) used to treat an underactive thyroid gland (hypothyroidism). Because not all brands of levothyroxine sodium are equivalent, it is important not to switch between brand names or even between generic formulations. Also, it can take several months to get to the proper dosage of this medication. Therefore, most doctors do lab work approximately every three months.

Synthroid tablets 50mcg contain levothyroxine, a synthetic thyroid hormone that is identical to the naturally occurring thyroid hormone thyroxine or T4 and substitutes for the lack of thyroid hormone in hypothyroidism (underactive thyroid gland) to regulate normal growth and metabolism.
