- 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 (levothyroxine sodium) ®.

If you are taking anticoagulants (blood thinners), your clotting status should be checked frequently.
- Use LEVOXYL (levothyroxine sodium) ® 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.

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 (levothyroxine sodium) ® in the morning on an empty stomach, at least one-half hour before eating any food.
