My daughter has an itchy rash on both arms, more on the underside. She was taking Augmentin for a severe sinus infection so was on her second 10 day script when it started. It s getting worse. She has taken before and no h/o of antibiotic allergy. I have a picture if that is possible. 17 yo . Healthy otherwise. She does have vitiligo and when I was searching for possible best course of treating this rash - lupus rash came up so now I am mildly concerned because I remember her doc at CHOP mentioned a lupus, thyroid and others to keep an eye on with her autoimmune disease. I know it s a stretch and assuming this could even just be r/t dermatitis. Suggestions?
