I was on hydroxychloroquine for approximately 3 1/2 weeks when I woke up one morning and was covered in a rash from my chest under my breasts. It spread through my whole body and took five separate courses of prednisone to calm down the drug eruption it scared my previous rheumatologist to the point where she was under medicating me for Ari and I got to the point where I almost couldn’t walk. Luckily I am now on a better medication and have a competent rheumatologist.
