Re: How long does it take to clear synthroid from system

I am not sure, but I read somewhere that half-life of thyroxine is 7 days, which means that if you take, say, 100 mcg every day over some period of time and stop, then:

in first 7 days - 50 mcg (=100\2) remains in your system
in next 7 days - 25 mcg (=50\2) remains,
in next 7 days - 12,5 mcg (=25\2)remains
and so on.

But it is not exactly correct, because thryoxine builds up in your tissues, and overall amount in your entire body - stored and circulating - is not 100 mcg, but .. (400 mcg?..) or so.

I read it somewhere when I was browsing Interent for something else, now I cannot find this place... I also would like to know, how you can judge that all your medication came out?
