My son has pneumonia and has a rash that comes and goes. It looks like hives in places and blisters the size of his fist or bigger in others. It is very itchy and looks very angry. I am wandering how long I can expect this to last. He has had 4 doses of amoxicillin and I am worried about distinguishing this rash from a possible reaction to the antibiotic.
Hi, You may be right. The rash in the form of hives or urticaria may be due to antibiotic. Amoxicillin. However, consult the dermatologist for the perfect diagnosis. I would recommend you to stop amoxicillin and to take antihistamines like cetirizine and if needed, oral steroid in tapering dose. Hope this helps. Chat Doctor.
