Any
generic T4 med is very inexpensive. However,
Cytomel, a T3 drug, not so much. The
Cytomel, to ease your mind, you will only be taking for a very short time. You take this prior to your surgery and pre-RAI only. Because T3's short lived in the body (about 4 hours), they can take you off of any T4 meds early, prior to surgery. Then they don't have to wait and weene you off post surgery and wait for RAI. Because of this, you will be quickly ready for RAI.
