Taken off Levo.

I went to the endo about 6 weeks ago and she took me off the Levothyroxine.  I am suppose to retest about now to 8 weeks.  I was just wondering if any of you knew how long it takes for the Levo to leave the body and the thyroid to take over again.  I was on levo for 4 months.
Does it make a difference if I wait 2 more weeks?

This is not a big deal.  If you wait long enough, 8 weeks,  it will be correct.

So when I go get retested the results won't be accurate? I can't seem to find anything on the web to help me out.  I just want to make sure when I get retested it is the correct level being tested. I am sure I won't be retested if it is normal, but if its normal, then is it really? or is it lingering Levo?

one levothyroxin pill last 6 1/2 days in our system.  add that to the pills already taken to date.  
i believe that is longer than a week.  8 weeks sounds more feasible.

armour has a shorter shelf life, so will have a shorter time lasting in the system.

wait the the other 2 weeks to make it a total of 8.  better to be safe.

I too have this question - have read 48hrs to 72hrs for Armour and up to 6 1/2 days for synthetic - I would especially like to know answer too - also saw your other post and I too feel best at 10 Tsh and my doctor is fine w/ up to 10 but not over. Anxious to see what input you get from others
