Thyrox 75 mcg contains Levothyroxine, a synthetic form of the thyroid hormone T4. It is prescribed to patients with Hypothyroidism (underactive thyroid).

8. How It Works
-
Levothyroxine replaces the body’s natural T4 hormone when the thyroid gland cannot produce enough.
-
It converts into T3, the active hormone responsible for:
