.. yes..I did mean microgram (mcg.) Nick

As you have written: " I take 350mcg=.350mg " the way it is written (with the

decimal) " reads " as..

0.350th of a milligram mg. ie. is a _part of or division_ of one whole

milligram. (1.0mg.)

0.350 mcg. (microgram) is just a bit more than one third of a mg. (milligram)

If one were a large horse or elephant then, perhaps.. one would be taking mg.'s

(milligram's) of thyroxine. But for humans.. mcg.'s (microgram's) will do just

fine. We don't want to kill anyone just treat 'em.

mcg

Stands for " microgram " or one-millionth of a gram. It is not an 'officially'

approved abbreviation. It should be written µg

However, the difficulties of printing the Greek letter " µ " led to the use of

" mcg " .

0.125mcg of t4 ='s an average dose of thyroxine mcg. = micrograms

Two 12.5 mcg. of Cytomel is equal to 0.025 mcg, total.

To the left <-- of the decimal point --> 1.000 is valued as a milligram (mg.)

(1. milligram plus 0.125 micrograms equals 1.125 milligram(s).

To the right --> of the decimal point 0.125 is valued as a microgram (mcg.)

" For well-differentiated thyroid cancer, TSH is generally suppressed to less

than 0.1mU/L. Doses of Synthroid greater than 2mcg/kg/day are usually

required. " (Dr. Ain)

(2mcg. is written as.. 0.002/kg/day)

Cytomel is equivalent to four times as much t4. This means that 0.025 mcg

Cytomel is equal to 0.100 mcg of thyroxine.

If one takes 0.125 mcg of thyroxine together with 0.025 mcg of Cytomel the

combined effect would be equal to taking 0.225 mcg of t4 thyroxine, alone.

You're welcome,
