Does anyone know about adalimubab biologic treatment for colitis and it possibly causing psoriasis rash on the back and torso? DP has nearly had all required injections and was doing very well but last few days nearing the final injection he's come out in what looks like a psoriasis rash. Not sure if this will subside or if it's looking like he might need to try another biologic, he was on azorhioprqne which was horrendous so we were really hoping this would work and looks to be until this rash appeared....
