Just came across this blog, some interesting info on it. I am athyreotic after thyroidectomy due to Graves, and seemingly will only grow to rue that decision in time, because 3 years post-surgery, I've changed one problem for another... Even with continually suppressed TSH (it just won't raise no matter how low a dose they put me on), I've gained 16 lbs while watching diet lots more carefully than before and staying active 5-6x a week... Anyway, I just learned that Euthyrox changed formulation a while back such that its excipients include maltitol now, vs the lactose it did in the prior formula. In theory that should be good, because lactose can impair levothyroxine absorption, but the thought of being somewhat of a Guinea pig does not inspire trust.

ReplyDeleteI had problems replying for some weeks. Apologies.
DeleteIt contains mannitol (not maltitol).
The Aristo and Henning formualtions contain neither mannitol nor lactose.
