Hi, I am glad that you are starting to feel better. I have always been told that what it takes to ACHIEVE remission (medication-wise) is what it takes to MAINTAIN remission long term.
It sounds like you had a very serious flare of crohn's and through experience, I know that often though we're feeling better, we can still have active disease in our GI tract that can be damaging. Prednisone can be a wonder drug and can carry us through some rough patches, but it is definately not something you want to be on for a very long period of time as there are very serious side effects to your health with extended use.
I've been on Remicade in the past and was very very happy with the results. Out of all the meds I've been on (Azothiaprine, Remicade, Humira, Cimzia, among many others) I believe it had helped me the most. The only reason I stopped is bc I had an allergic reaction--uncommon. You will definately want to talk with your GI specialist about this, but I am pretty positive that Remicade is not a med that you do once or twice and then stop. It is a med that you will do "loading doses" of infusions closer together and then maintain dosage of infusion every 8wks.
Please take the MAINTENANCE of your health very seriously. I also have very severe crohn's. In the past, I haven't had insurance and had been off meds, maintaining the best I could with toughing it out and the occasional regimen of prednisone. I believe that I did myself a disservice and during that time, disease was permanently damaging my GI tract and now I do have serious consequeses from that. I've had many abcesses/fistulas and now a permanent colostomy. Though I am at peace with my health status, in retrospect, I wish I had found a way to better maintain a consistent remission of disease and inflammation.
Hope you find a way to keep feeling your best, whatever you may decide!
