Without a Prescription

Synthroid is prescribed for use alone or in combination with antithyroid agents to treat hypothyroidism, goiter, chronic lymphocytic thyroiditis, myxedema coma, and stupor.
Synthroid is the same as the hormone thyroxine, which is usually produced naturally by the thyroid gland.
Where this does not happen, Synthroid tablets are given to replace this thyroxine.
