Bugdustt posted a topic in Side Effects - It Turned Me into a Newt! A Newt? I Got Better.I've been on 2 mg of Rex for 2 1/2 weeks now. It's been amazing. About 3 days ago I noticed a rash on my left shoulder. It is really tiny bumps with white heads on them like tiny pimples. They have a slight itch as well. I thought nothing of it until applied some hydrocortisone to the affected area a couple of times a day for 2 days. Needless to say the rash is still there and has spread to my other shoulder. Could this be caused by the rexulti? I read that one of the side effects is a rash. Has anyone experienced this? Tonight I took a benedryl.
