Medicines and surgery
Hypothyroidism is readily treatable using tablets containing thyroid
hormones, and the symptoms usually improve within days to weeks. Iodine
deficiency can be corrected with iodine supplements.
Hyperthyroidism is initially treated using combinations of therapies.
The overactivity of the gland is reduced using drugs such as carbimazole,
and beta-blockers are used to slow the heart rate and reduce any tremor.
The treatment of Grave's disease is to shrink the gland using radioactive
iodine, which is very safe.
It may be necessary to treat goitres with surgery.
Cancers of the thyroid are often removed surgically, although some can
be successfully treated with radioactive iodine. Some types of thyroid
cancer may spread to other organs. If the tumour is detected early, the
outlook is usually favourable. If the gland is removed during surgery
or destroyed by radioiodine treatment, thyroid hormone replacement may
The American Thyroid Association (ATA) endorses the use of potassium
iodide (KI) to protect people from absorbing radioactive iodine released
during a nuclear emergency. High levels of radioactive iodine exposure
can cause thyroid cancer, especially in babies and children up to 18 years
of age. KI reduces the risk of thyroid cancer in exposed populations.
ATA advocates KI as an essential adjunct to evacuation, sheltering, and
avoiding contaminated food, milk, and water
Thyroid hormone suppression therapy
Thyroid hormone suppression therapy is a form of treatment that involves
giving a patient a pharmacologic preparation of thyroid hormone in an
attempt to try to shrink a thyroid nodule. It is often started on a trial
basis when a nodule has been evaluated and is known to be benign. It may
also be started as part of the process of evaluation to help determine
whether a nodule is likely to be cancer.
In essence, thyroid hormone suppression therapy consists of giving a
patient a dose of thyroid hormone that suppresses TSH, and then monitoring
to see if this helps shrink a nodule.
Levothyroxine, also known as T4, is the predominant form of thyroid hormone
produced by the thyroid gland and released into the bloodstream. It is
converted to another form of thyroid hormone called triiodothyronine,
also known as T3, which is more active in different tissues in throughout
the body. The pharmacologic preparation of levothyroxine is identical
to the natural form that is produced by the body. It is manufactured under
a number of different trade names including Synthroid, Levoxyl‚
and Levothroid. Levothyroxine is also available in generic preparations.
It is available in a number of different doses.
With more than eight million users, Synthroid is one of the leading medications
in the treatment of hypothyroidism (underactive thyroid). Although Synthroid
has been available since 1955,
