Can only take accord or actavis and almus but not Teva. Any one know why?

Does it matter, as long as there are brands that work for you?

it’s likely to do with the fillers (excipients). Teva uses mannitol which some people react to. The others use lactose among other things. helvella has an amazing document with all of them listed .

Actavis was simply renamed as Accord a while after ownership of the company changed.
Almus is Accord but put into Almus boxes. Look on the card outer - it says Accord.

MiloMutley I couldn't tolerate TEVA at all, very bad gut issues and came to the conclusion it was the acacia powder filler in the tablets. I used to take Almus/Accord but now take Vencamil/Aristo alongside some Sigma Pharma liothyronine and no longer have any gut issues. I am also Gluten free and avoid normal milk and cream , have Lactose free items instead. OK with cheese and yoghurt as lactose in them is very low and pills with lactose not a problem for me.
Lots of people can't tolerate Teva.
