What is liotrix?

Liotrix is a man-made form of a hormone that is normally produced by your thyroid gland to regulate the body’s energy and metabolism. Liotrix is given when the thyroid does not produce enough of this hormone on its own.

Liotrix is used to treat hypothyroidism (low thyroid hormone).

Liotrix is used in combination with antithyroid medication to treat thyrotoxicosis (excess thyroid hormone).

Liotrix is also used to treat or prevent goiter (enlarged thyroid gland).

Liotrix is also given as part of a medical tests for thyroid disorders.

Liotrix should not be used to treat obesity or weight problems.

Liotrix may also be used for purposes not listed in this medication guide.

You may not be able to use liotrix if you have thyrotoxicosis or an adrenal gland problem that is not controlled by treatment.

Stop taking liotrix 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.

Since thyroid hormone occurs naturally in the body, almost anyone can take liotrix. However, you may not be able to use this medicine if you have:

  • an adrenal gland problem that is not controlled by treatment;

  • thyrotoxicosis that is not treated with antithyroid medication; or

  • certain heart conditions.

Tell your doctor if you have ever had:

  • problems with your pituitary or adrenal gland;

  • heart disease, angina (chest pain);

  • coronary heart disease;

  • pernicious anemia;

  • 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 liotrix?

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 liotrix, and may need a lower dose than adults younger than 65.

Your thyroid function will need to be tested often. Even if you have no symptoms, tests can help your doctor determine if liotrix 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 liotrix.

What should I avoid while taking liotrix?

Follow your doctor’s instructions about any restrictions on food or beverages. You may need to avoid certain foods that are high in fiber and can make it harder for your body to absorb liotrix.

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