What is LEVOXYL?

LEVOXYL is a prescription medicine that contains a hormone called levothyroxine, which is similar to the hormone produced by your thyroid gland. LEVOXYL is used to treat children and adults:

• to replace or give extra levothyroxine in people whose thyroid does not produce enough of this hormone.
• who need surgery and radioiodine therapy to manage a type of thyroid cancer called well-differentiated thyroid cancer.

LEVOXYL should not be used to treat people who are recovering from swelling of the thyroid gland (thyroiditis) and whose bodies do not produce enough levothyroxine for a short time.Do not use LEVOXYL if your adrenal glands are not working well and you have not been treated for this problem.Before you take LEVOXYL, tell your healthcare provider about all of your medical conditions, including if you:

• have or had heart problems.
• have or had thyroid nodules.
• have adrenal or pituitary gland problems.
• have any food or drug allergies.
• have a low red blood cell count (anemia).
• have diabetes.
• have weak bones (osteoporosis).
• have or had a history of blood clotting problems.
• have recently received radiation therapy with iodine (such as I-131).
• are pregnant or plan to become pregnant. Your healthcare provider may need to increase your LEVOXYL while you are pregnant.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements. LEVOXYL may affect the way other medicines work, and other medicines may affect how LEVOXYL works. You can ask your healthcare provider or pharmacist for a list of medicines that interact with LEVOXYL.Tell every healthcare provider including your dentist who treats you that you are taking LEVOXYL before any surgery.
