In December 2012, Virginia House Delegate John M. O'Bannon, III introduced the Interchangeable biosimilar biological products bill (H.B. 1422). This proposed legislation seeks to permit pharmacists to dispense a biosimilar drug that has been licensed by the U.S. Food and Drug Administration as interchangeable with a prescribed biological product unless the prescriber indicates such substitution is not authorized or the patient insists on dispensing of the prescribed biological product.
