About:Levoxyl, a synthetic thyroid hormone may be given in any of the following cases:
- If your own thyroid gland is not making enough hormone;
- If you have an enlarged thyroid (a goiter) or are at risk for developing a goiter;
- If you have certain cancers of the thyroid;
- If your thyroid production is low due to surgery, radiation, certain drugs, or disease of the pituitary gland or hypothalamus in the brain.
How Taken:Take Levoxyl as a single dose, preferably on an empty stomach, one-half to one hour before breakfast. The drug is absorbed better on an empty stomach. If an infant or child cannot swallow whole tablets, you may crush a Synthroid tablet and mix it into 1 or 2 teaspoonfuls of water.
While taking Levoxyl, your doctor will perform periodic blood tests to determine whether you are getting the right amount. If you are taking Levoxyl to make up for a lack of natural hormone, it is important to take it regularly at the same time every day. You will probably need to take it for the rest of your life.
Missed Dose:Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time. If you miss 2 or more doses in a row, consult your doctor.
