I just took brand synthroid for 4 days and thought I was going to die! Cough, allergies, burning in my head, dizzy...you name it! Never again will I touch that stuff. Also..what I talc? When you read the ingredients you have to wonder what is going on..
I would suggest to anyone allergic to the fillers in levothyroxine tablets (whether brand name or generic) trying Tirosint. It's the same active ingredient as levo tablets, but is a gelcap no fillers, except water) and hyopallergenic. Dessicated is a possible alternative also, but not everyone can or should try to tolerate the high T3 content in dessicated (depending on other health problems, general health, age, etc.). Our members who have tried Tirosint seem to have good things to say about it.
Talc is a mineral...it's the main ingredient in talcum powder, but has a wide range of uses.
