Safety Considerations for Using LEVOXYL

Before you start, and while you are taking medication to treat your hypothyroidism, there are important things that you should know and discuss with your doctor. The information below summarizes some important safety considerations for LEVOXYL. Please see the full Prescribing Information for additional Important Safety Information.

Information for Patients 

Patients should be informed of the following information to aid in the safe and effective use of LEVOXYL:

Notify your physician if you are allergic to any foods or medicines, are pregnant or intend to become pregnant, are breast-feeding, or are taking any other medications, including prescription and over-the-counter preparations.

Notify your physician of any other medical conditions you may have, particularly heart disease, diabetes, clotting disorders, and adrenal or pituitary gland problems. Your dose of medications used to control these other conditions may need to be adjusted while you are taking LEVOXYL. If you have diabetes, monitor your blood and/or urinary glucose levels as directed by your physician and immediately report any changes to your physician. If you are taking anticoagulants (blood thinners), your clotting status should be checked frequently.

Use LEVOXYL only as prescribed by your physician. Do not discontinue or change the amount you take or how often you take it unless directed to do so by your physician.

Not an actual patient.

The levothyroxine in LEVOXYL is intended to replace a hormone that is normally produced by your thyroid gland. Generally, replacement therapy is to be taken for life, except in cases of transient hypothyroidism, which is usually associated with an inflammation of the thyroid gland (thyroiditis).

Take LEVOXYL in the morning on an empty stomach, at least one-half hour before eating any food.

LEVOXYL may rapidly swell and disintegrate, resulting in choking, gagging, the tablet getting stuck in your throat, or difficulty swallowing. It is very important that you take the tablet with a full glass of water. Most of these problems disappeared when LEVOXYL tablets were taken with water.

It may take several weeks before you notice an improvement in your symptoms.

Notify your physician if you experience any of the following symptoms: rapid or irregular heartbeat, chest pain, shortness of breath, leg cramps, headache, nervousness, irritability, sleeplessness, tremors, change in appetite, weight gain/loss, vomiting, diarrhea, excessive sweating, heat intolerance, fever, changes in menstrual periods, hives or skin rash, or any other unusual medical event.

Notify your physician if you become pregnant while taking LEVOXYL. It is likely that your dose of LEVOXYL will need to be increased while you are pregnant.

Notify your physician or dentist that you are taking LEVOXYL prior to any surgery.

Partial hair loss may occur rarely during the first few months of LEVOXYL therapy, but this is usually temporary.

LEVOXYL should not be used as a primary or adjunctive therapy in a weight control program.

Keep LEVOXYL out of the reach of children. Store LEVOXYL away from heat, moisture, and light.
