My son has been on Imuran for one month now while tapering his Prednisone. He is feeling great and has just overcome a cold, but has also had a few warts pop up since starting the Imuran. He is 10 and weighs 65 pounds (was at 57lbs. when diagnosed two months ago). He is currently on 75mg of Imuran. I have been googling all of the awful possible Imuran side effects and am in desperate need of encouragement! Also, our pediatric GI specialist has not been testing his blood on this medicine. He said he wants to see him after two months and will check his blood then, should I be concerned about this? Any advice/encouragement is greatly appreciated! Thank you!
