I have had two docs tell me to use synthroid only - the generic is "unreliable" and "it could come from honduras for all he knows" that "each
pill of generic could be different, you might get 80 mcg today and 99 tomorrow" and that the pharmicist "makes more money from the generic, that's why they push it".
Synthroid has been known to have been "spiked" - have additional med in it than it says ( and it performs "better" than the same dose of a generic -as jade says, if you happen to need more). One FDA presentation says our docs want to know that switching products poses no patient risk. But obviously, if Synthroid contains more T4 than a generic yet it SAYS it is the same dose, this is WRONG to do. Of course, instead of being ok for you when you switch brands if you need more T4, it could be worse if you need less and throw you into hyper.
Public Meeting for Levothyroxine Sodium Therapeutic Equivalence
May 23, 2005, Washington, DC:
lots of presentations. I also found an article in the "Formularly Journal" about the levothyroxine spectrum: Bioequivalence and cost considerations
This was interesting:
Section E 2. Overages was interesting -the proposed shelf life should not depend on the existence of a stability overage. In other words, don't spike it! Make them like aspirin - all brands with the same amt of meds.
Pharmacist I asked last night about the $$ difference they make from synthroid/generic didn't know - but said they were TAUGHT
that the generic was the same as the brand name.
In the end, when your doc gets your TSH or whatever he measures by, to where YOU feel normal, it shouldn't matter WHICH one you are taking - it is the right amount for YOU.
Does anybody really know?
