Key points

  • SYNTHROID has a narrow therapeutic index, so too much or too little treatment can affect several body functions.
  • TSH is not a reliable way to judge treatment level in secondary or tertiary hypothyroidism.
  • SYNTHROID tablets contain no ingredients derived from wheat, barley or rye.

What Levothyroxine is used for

Levothyroxine sodium supplies T4, a thyroid hormone that the body converts partly to the more active T3. It is listed for Hypothyroidism and may also be used with surgery and radioiodine therapy for Thyroid-stimulating Hormone Suppression in thyrotropin-dependent well-differentiated thyroid cancer.
