I found a post from 4 years ago about different makers of levothyroxine and how some people felt worse after a change of manufacturer. No one mentioned teva so I think it must be new -I have not seen it until about 3 months ago when I was given this by the pharmacy I always use. I have 75mcg. I am halfway through my third month on it and have started to feel less well. Nothing else has changed, has anyone else tried this maker?
