What is Cytomel?

Cytomel is a man-made form of a hormone that is normally produced by your thyroid gland to regulate the body's energy and metabolism. This medicine is given when the thyroid does not produce enough of this hormone on its own.
Cytomel treats hypothyroidism (low thyroid hormone). This medicine is also given as part of a medical test for thyroid disorders.
Cytomel is also used together with surgery and radioactive iodine therapy in people with thyroid cancer.
Cytomel should not be used to treat obesity or weight problems.
Cytomel may also be used for purposes not listed in this medication guide.

Warnings

Cytomel should not be used to treat obesity or weight problems.
You may not be able to use Cytomel if you have an adrenal gland problem that is not controlled by treatment.
Stop taking Cytomel and call your doctor if you have symptoms of thyroid toxicity, such as chest pain, fast or pounding heartbeats, feeling hot or nervous, or sweating more than usual.

Before taking this medicine

Since thyroid hormone occurs naturally in the body, almost anyone can take Cytomel. However, you may not be able to use this medicine if you have an adrenal gland problem that is not controlled by treatment.
Tell your doctor if you have ever had:
• problems with your pituitary or adrenal gland;

• heart disease, angina (chest pain);

• a bleeding or blood clotting disorder;

• diabetes; or

• osteoporosis or low bone mineral density.

Tell your doctor if you are pregnant or breastfeeding.
Follow your doctor's instructions about using this medicine if you are pregnant. Controlling your thyroid hormone levels is very important during pregnancy, and your dose needs may be different during each trimester.

How should I take Cytomel?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Older adults may be more sensitive to the effects of liothyronine, and doses are generally lower for people in this age group.
If you are switching to Cytomel from any other thyroid medicine, stop using the other medicine before you start taking this medicine.
Cytomel doses are based on weight (especially in children and teenagers). Your dose needs may change if you gain or lose weight.
When given as part of a thyroid suppression test, you will need to take Cytomel for several days in a row in preparation for the test. Tell your doctor if you miss any doses during this time.
Your thyroid function will need to be tested often. Even if you have no symptoms, tests can help your doctor determine if this medicine is effective.
If you need surgery, tell your surgeon you currently use this medicine. You may need to stop for a short time.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Cytomel.
Keep using this medicine as directed, even if you feel well. You may need to take thyroid medication for the rest of your life.
Store at room temperature away from moisture and heat.

What should I avoid while taking Cytomel?

Do not change brands or change to a generic product without first asking your doctor. Different brands of liothyronine may not work the same. If you get a prescription refill and your new pills look different, talk with your pharmacist or doctor.
