Re: T4 in Synthroid equal to T4 portion in Armour

[Guest guest]

Hi HD-

There is a difference of 1000 between micrograms and milligrams. Although

Armour is manufactured in 60 mg tablets (1 gr), there are roughly only 38

mcg of T4 and 9 mcg of T3 per tablet (PDR 2003). The rest of the tablet is

dye and fillers.

In answer to your question, you'd need 38 mcg of Synthroid to equal the 38

mcg of T4 in Armour. Since Synthroid only comes in 25 or 50 mcg pills, your

doctor would probably prescribe either one or the other.

Take care,
