Levothroid^® (levothyroxine sodium tablets, USP) is a synthetic product containing the hormone levothyroxine (T₄). It is indicated for the treatment of hypothyroidism. Levothroid is available in 12 strengths ranging from 25 mcg through 300 mcg to allow for proper titration of thyroid function.¹ This gives your doctor a range of options to prescribe the most precise dose for your particular needs.

Thyroid hormones should not be used for the treatment of obesity.

Levothroid tablets should be used with caution in patients with cardiovascular disease, including hypertension. The development of chest pain or other exacerbation of cardiovascular symptoms will require a decrease in dosage. Thyroid hormone may increase symptoms of diabetes mellitus, diabetes insipidus, or adrenal insufficiency. Adjustment of treatment measures for these endocrinological diseases is necessary if thyroid hormone therapy is added. If Levothroid is used in the treatment of myxedema coma, glucocorticoids should be administered.

Levothroid is available by prescription only.
