My dr gave me 5mcg rx for cytomel and told me to come back in 30 days for a recheck. But...with the short life of cytomel, does it really take 30 days to get into the system as it takes T4 to get the system? I want to get started on T4. I really can't wait so long - I've waited long enough (years) I need relief!

cytomel/T3 takes at most a week to get into the system, and you should feel (or not) some relief in a couple of days, at least so that you know it's doing the job; i think your doctor is (a bit!) lazy on that score ...

i don't know why he didn't give you synthroid (T4), and unfortunately you haven't posted your numbers (TSH, freeT3, free T4 ideally, but at least a TSH ... do you have them? even your TSH? why is he giving you cytomel? (for me, it works for the worst depression i've ever had, but mine's a pretty bad case of hypothyroid, and went undetected for at least a year) ...

i don't know what a THBR test is, and i would have thought a freeT3 should do it, but there are more experienced people than me on this board ...

i found a definition that implies that it's a test for hypERT? could that be the case?

here it is:

"The Free Thyroxine Index (FTI) is the calculated product of T-3 resin uptake and serum total thyroxine (T-4) and is the best initial screening test for hyperthyroidism. It permits correction of misleading results in T-3 and T-4 determinations caused by conditions that alter the thyroxine-binding protein concentration (e.g. pregnancy estrogens birth control pills). The American Thyroid Association now recommends the term thyroid hormone-binding ratios (THBR)."

pretty dense, eh?? but it DOES have to do w/T3, in answer to your question ...

you could do your own search ... i recommend Google ...
