Uses & Benefits
Hypothyroidism (underactive thyroid), congenital hypothyroidism, thyroid hormone replacement after thyroidectomy or radioiodine therapy, TSH suppression in differentiated thyroid cancer (as advised by specialist)
How It Works
Levothyroxine is a synthetic form of thyroxine (T4), a natural thyroid hormone. It is converted to the active hormone triiodothyronine (T3) in tissues, which regulates metabolism, energy, growth and body temperature, thereby normalizing thyroid function and TSH levels.
