Thyrolar
Thyrolar® is the only synthetic product combining L-triiodothyronine (T3) and levothyroxine sodium (T4) indicated for the treatment of hypothyroidism.
Thyroid disease is one of the most common disorders in the United States, with about
27 million people suffering from some form of the disease. When the thyroid is either
underactive, nonfunctioning, or has been all or partly surgically removed, hypothyroidism
may occur. If left untreated, hypothyroidism and its symptoms usually worsen.
The traditional treatment for hypothyroidism is thyroid hormone replacement. This
involves taking levothyroxine (T4) , liothyronine (T3) , or
a combination product containing both T4 and T3. These treatments
work in the body much like thyroxine, the human hormone normally produced by the
thyroid gland.
Safety Information
Precautions
Thyroid hormones should not be used for the treatment of obesity.
Thyrolar 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 for these endocrinological diseases is necessary if thyroid hormone therapy
is added. If Thyrolar is used in the treatment of myxedema coma, glucocorticoids
should be administered.
