hi! i am currently on remicade. I will be 16 in less than 4 days!!! [march 4] i was 14 when i started taking it. it was in oct. 2006. It started really helping me after about the 6th treatment. I had a couple of reactions. They were shortness of breath and my heartrate was really high. that happened twice. Then i also got shortness of breath one time later at night. and it gave me really bad migraines until about the 9th treatment. But it has helped me a lot. it really is a miracle drug. it effects everyone's body differently so i guess it's different for everyone. like it will not help everyone. but i love it and i have had 12 or 13 treatments.. haha i forget. i hope it works well for you!! and yeah you need to be more careful because it is an immunosuppressant. i am also on imuran which is an immunosuppressant, so if you are on that as well, you have to be very very careful hah. that is why i carry around bottles of hand sanitizer.. haha.
