I have seen many on the patient to patient thyroid
community see dramatic differences from generic vs
. brand-name. They may never know why.
I believe to be consistent when you take your meds, how long you wait to eat afterwards, when you have your bloodraws taken and that the same mfg. makes the meds.
Just my 2 cents as a patient on 75mcgs name brand Synthroid.
Synthroid may give coupons/discounts on their website if that is helpful.
