I can tell you from experience that the Remicade is giving you the weird acne. I took my first 2 infusions while I was still on Prednisone, which masked the effects. I could see like a weird prickly heat. than after my third infusion, and off the Prednisone, I started really breaking out. Currently I'm only on Pentasa and I'm not going to take Remicade anymore, I don't think it helped and it also screwed my mind up. My dermatologist was familiar with Remicade. He didn't think it caused the acne, but he's given me a prescription of Brevoxyl cream for my face along with 500 mg of Amoxocylin twice a day. neither has any bad effect for the crohns. I have only gotten more spots from the small little dots that were held back from the prednisone. nothing new. if you google, "remicade and acne" you see some other people who got it.
