I switched from Remicade to Renflexis and it did NOT work the same for me, even though everyone said it should be the same. I had a bad flare and my doctor fought insurance to get me back on Remicade, the only thing that works for me. A nurse closed the door to my infusion room and told me quietly that a lot of Crohn’s patients are experiencing the same thing.
It’s worth a try though because if it works, that’s great because it’s so much cheaper. I had high hopes for the biosimilar. It did take me about a year back on Remicade to get back to feeling as good as I had before they changed me to Renflexis. It was an awful time during which I cursed the insurance company something fierce. Now the company that makes Remicade pays all my out of pocket costs except $5.
