It may be that Doctors are favoring Entyvio over Remicade due to less side effects and/or more targeted mechanism of action, although I would like to hear if that is in fact the reasoning of BS's doctor. My doctor did mention to me that Entyvio has a different mechanism of action than Remicade. I am looking at Entyvio as my "relief pitcher" in the bullpen should I ever develop antibodies against Remicade.
