Thyroid-stimulating hormone (TSH) suppression therapy may be given to shrink noncancerous thyroid nodules. This uses medicines
such as levothyroxine (for example, Synthroid, Levoxyl, or Levothroid),
liothyronine (for example, Cytomel), liotrix (Thyrolar), or desiccated
thyroid (for example, Armour Thyroid).
It is not clear how well
thyroid-stimulating hormone suppression therapy works to shrink noncancerous
thyroid nodules. If you have a noncancerous nodule, talk to your doctor about
whether TSH suppression therapy is right for you.

therapy can raise your risk of heart and bone problems, especially if you have
heart disease or
osteoporosis. If you have heart disease, this kind of
medicine can make chest pain or problems with your heart rhythm worse. It can
also raise your chances of
heart attack. If you have osteoporosis, TSH
suppression therapy can further weaken your bones.
What to think about
Hypothyroidism (too little thyroid
hormone) occurs in some people after being
treated with radioactive iodine for thyroid nodules.
For this reason, your doctor will check your thyroid hormone levels regularly
after you have this treatment.
If a thyroid nodule is not
cancerous but is making too much thyroid hormone, causing
hyperthyroidism, antithyroid medicines may be used
before radioactive iodine treatment. For more information on treating
hyperthyroidism, see the topic
