I started Remicade infusions almost 4 years ago with no side effects. I also take Lialda. And yes I was scared. I do take premeds Claritin and Tylenol before each infusion.
My maintenance dose has been 10mg/kg every 6 weeks for all these years. But I had gotten into a bad/severe flare over the last months caused by the cancer drug Tagrisso. My Calprotectin level was 822 and my C-reactive protein was high too.
So I stopped the drug tagrisso and we moved my Remicade infusion up to 10mg/kg every 4 weeks. I was really afraid it wouldn't work this time and I would have to move on to a different drug. But I was proved wrong and in 7 days I was feeling better and in 10 days I was in no pain and back to normal once again.
Remicade has been a miracle drug for me and it may be a miracle drug for you too.
Keep hanging in there and Good luck.
