it is a good idea to ask your pharmacist about the differences in brand and generic drugs. I take Synthroid (brand name thyroid replacement) because the absorbtion varies a lot with generics. The pahrmacist may be a better source of this info than your doc. Leta 53/53, (R.N. 31 years) _________________________________________________________ DO YOU YAHOO!?
