Product Information
Levothyroxine or L-thyroxine is a synthetic thyroid hormonethat is chemically identical to thyroxine (T4), which is naturally secreted by the follicular cells of the thyroid gland. It is used to treatthyroid hormone deficiency, and occasionally to prevent the recurrence of thyroid cancer. Like its naturally secreted counterpart, levothyroxine is a chiral compound in the L-form. The related drug dextrothyroxine (D-thyroxine) was used in the past as a treatment for hypercholesterolemia(elevated cholesterol levels) but was withdrawn due to cardiac side effects.
