Jack, I disagree with the use of the term "generic biosimiliars" as I consider it a misnomer. Since one cannot exactly duplicate a biologic medication and therefore cannot make an exact copy, the resulting medication is a "biosimilar". A generic medication is an exact copy of a chemical medication. Linking the two terms is both incorrect and potentially creates even more confusion from the implications. There should not be any differences with generics; we know there are differences with biosimilars. The amount of education necessary for both patients and providers about biosimilars is YUUGGGE and I believe we need to limit any potential implications that biosimilars are equivalent to generics whenever possible. But, as Dennis Miller used to say, "That's just my opinion; I could be wrong." Harry L Gewanter, MD, FAAP, FACR Richmond, VA US
