I have recently noticed that about 10mns after taking levothyroxine I get a burning in my stomach throat and mouth. I also get lots of rumbling sounds and feel very hungry. I take the meds correctly- empty stomach and with plenty of water. I don't think I got as severe symptoms when I took the brand Eltroxin but there have been problems with getting it recently and it's a more expensive brand! It's def the tablet that is causing this as I do t normally suffer with digestive problems . Does anyone here take liquid thyroxine or purified Levo as I have a hunch it's the fillers that are causing this problem.
