I was on Remicade for 12 years. I go way back to the days that the infusions were at 0 weeks, 2 weeks, and 6 weeks from Day 0 (Week 0) and then that was it. In theory your body was supposed to have forgotten how to make the faulty T-cells and you'd be sympom free from then on.
Fortunately they figured out that it was a maintenance dose kind of drug and I was on it every 8 weeks. I felt a little off on infusion day but that was probably due to the pre-meds. It was about 10 years before I needed the pre-meds. Anyway, within a few days of getting my infusion I felt better than I had in years. I had energy and I had an appetite. Around week 7 I started feel what I called "punky" but then I was back to being 100% a day or two after infusion.
I had only 1 Crohn's surgery during those 12 years and that was to deal with a fistula that had popped up prior to Remicade.
Since I've had Crohn's since I was 17 and had a bunch of surgeries when I was 21 I always got the best insurance my employer offered. Remicade was $5,000 a shot back then but I only paid $50 at the GE. The hospital's infusion center added all kinds of fees that jacked the price up to $500 and the service was worse!
I did Stelara later and as others have said Centicore had a program where they'd reimburse your co-pay less $5.
So do your homework. If they want to much to infuse you look for a cheaper infusion center. If the manufacturer has a program to lower the fee then look closely.
Note that if you have a Flexible Spending Account you CANNOT then go to that for further reimbursement. That could get you banned from the company's rebate program.
I hope Remicade helps you as much as it helped me.
