From the Guidelines

Tirosint (Levothyroxine) is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone.

Common Uses

  • Treatment of overt hypothyroidism
  • Treatment of subclinical hypothyroidism, although the likelihood of improvement is considered small and should be balanced against the potential risks of therapy 1

Important Considerations

  • Levothyroxine may be prescribed for patients with subclinical hypothyroidism who have symptoms compatible with hypothyroidism, but the decision to continue therapy should be based on clear symptomatic benefit 1
  • The natural history of subclinical hypothyroidism and the risk of progression to overt hypothyroidism should be considered when making treatment decisions 1

From the FDA Drug Label

TIROSINT-SOL is a prescription medicine that contains a hormone called levothyroxine which is normally produced by the thyroid gland TIROSINT-SOL is used: to replace or give extra levothyroxine in people whose thyroid does not produce enough of this hormone; or with surgery and radiodine therapy to manage a type of thyroid cancer called thyroid-dependent well-differentiated thyroid cancer

Tirosint (Levothyroxine) is used for:

  • Replacing or giving extra levothyroxine in people with hypothyroidism (underactive thyroid)
  • Managing thyroid-dependent well-differentiated thyroid cancer with surgery and radiodine therapy 2
