What is Synthroid®?

> Synthroid is used when the thyroid gland does not produce enough hormone.

> It contains levothyroxine sodium, the same as the T4 hormone produced by the thyroid gland.

> It is intended to replace the T4 that is normally produced by your thyroid gland because low levels of T4
    affect the proper function of many of your organs and your metabolism.

Synthroid is usually taken for life – don’t stop
taking your medication, even if you are feeling better,
unless directed by your doctor to do so.

How do I take Synthroid®?

Take Synthroid as a single dose, preferably on an empty stomach, one half to one hour before breakfast.
Synthroid should be taken at the same time every day with a full glass of water.
As food and drink can change the absorption of Synthroid, be consistent in how you take it with regards to meals (either always take it on an empty stomach, which is preferred, or always take it with food).
Always take Synthroid exactly as your doctor has prescribed it.
If you forget to take a tablet, take it as soon as you remember, unless it’s almost time for your next dose. If it’s almost time for your next dose, take the dose you missed at the time you take your next dose.
If you miss two or more doses in a row, check with your doctor.
