My mom took remicade. She has several autoimmune problems. I cannot say my mom had long term good results, but short term she felt better. She is now on arrava (sp?) and is doing much better.
I was on Enbrel injections. They worked a bit, but not much. I just switched to humira last week. They are similar to remicade. With the kind of arthritis I have remicade is not supposed to work as well as the humira. But it is one of our next options (will have to try the humira for at least 4 months first).
I am so sorry your daughter is sick enough she needs this, but hopefully it will make a huge difference for her. Several of the women at the lupus/RA support group here absolutely love remicade. (Part of the love for 3 of them is the IV bit - they have small kiddoes and it is their "break" - they all go together and have a lovely time chatting!)
Hugs,
Susie
