Hello, I had been on Remicade for 4 1/2 years when my insurance required my changing to the biosimilar. Prior to the change over, I was having wonderful results with few flares and minimal pain between infusions. After the change to the biosimilar, my pain was back to what it was when I was first diagnosed. It was unbearable. Fortunately, with the documentation of my lack of relief from the new medication, my insurance approved my change back to Remicade. As far as insurance payment, I am on traditional Medicare with a Medicare Supplement which between the two covers my infusions in full.
