  • What is Westhroid?

    Westhroid is a medicine used to treat hypothyroidism (an underactive thyroid gland). Westhroid is a synthetic hormone that is intended to replace a hormone that is normally produced by your thyroid gland. It is also used to treat or prevent certain other thyroid conditions such as goiter (an enlarged thyroid gland); inflammation of the thyroid gland; thyroid hormone deficiency due to surgery, radiation, or certain medications; or for the management of certain thyroid cancers. Also, Westhroid is used for thyroid suppression tests as a diagnostic agent to evaluate your thyroid function.

  • What is the most important information I should know about Westhroid?

    Westhroid is a replacement therapy, so you need to take it every day for life unless your condition is temporary. Tell your doctor immediately if you experience chest pain, rapid or irregular heartbeats, excessive sweating, heat intolerance, or nervousness.

    If you have heart disease, your doctor may need to start you on a lower dose of Westhroid to see how you respond to the medication.
