Ive been forced to change brands and types of thyroid meds about 8 times in the last 20n years. Some of which is not even offered in the US today.
What I learned: Your body will almost NEVER make a smooth transition from one thy med to another.
Why? - Because of diff fillers used that WILL have effect on absorb ability to the INDIVIDUAL.
This means experiencing differing levels "un-comfortableness", flashes, hypo , hyper, flushed feeling - since it takes time for the receptors to recognize a new looking hormone. Optimal is not reached till even after the 6 week test point many times, but 6 week point is a pretty good idea, just not complete yet.
Again, changed 8 times, and more going back and forth since the US has complete history of manufacturing changes and limited and zero supply of certain brands in the past. This even costs people employment in the past. Its pathetic. Im really tired of continuous changes.
Even T4 only has changes , just not as often. The Puerto Rico manufacture facility was whipped out when the hurricane hit 2018-2017-2016? That brand was done for a while.
