In reply to Synthroid or Cytomel -what's the diff, posted by Maxime on February 2, 2004, at 9:56:11
Cytomel is liothyronine sodium (aka L-triiodothryonine or LT3), a synthetic form of the T3 thyroid hormone. Synthroid is levothyroxine sodium (aka L-3,3',5, 5'-tetraiodothyronine or T4), also a synthetic thyroid hormone.
Both drugs are indicated for hypothyroidism, among other things. Beyond that, I couldn't really tell you the difference! I'm not sure if they can be used interchangeably or what... perhaps someone else could answer this.
Just FYI, there are also formulations that contain both T3 and T4 -- Thyrolar and Liotrix are the two that I know of.
