The spots aren t itchy or irritating just appeared on body Sunday night and was Giving the antibiotics on Friday ? [/INST] Hello, I read carefully your query and understand your concern. The symptoms can be related to an allergic reaction to the antibiotic flucloxacillin. I suggest using an antihistamine such as Cetirizine 10 mg daily. I also suggest using Dexamethasone cream for local application. You should consult your doctor about an alternative antibiotic. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards! Chat Doctor.  </s>
