Just switched to synthroid 88 mcg after 8 yrs on Armour. My doctors found an ugly mass on my right thyroid and rushed me to surgery, certain it was Cancer: it was just an ugly goiter..now I have to take thyroid meds the rest of my life. :(
It took a year to get me regulated on Armour and I gained 30 #. 20:20 hindsite. I thought it was good and natural too... for 8 years
BUT here is an FYI: NOBODY TESTS THE PIGS. THERE IS NO QUALITY CONTROL TO SEE HOW MUCH THYROID WE ARE 'REALLY' GETTING.ANIMALS CAN BE HYPO AND HYPERTHYROID TOO.
Sooo... 7 weeks into a 90 day supply of my Armour and my pharmacy recalls it. I mention it to my doc who promply makes the connection and draws my labs, VOILA I am suddenly hyperthyroid AND now I can understand some of my crappy symptoms of late..
Lesson learned. Hoping to be feeling better soon. Hope you all find what works for you but these are all drugs and be aware.
