The redness, swelling and itchiness of ant bites should not be squeezed, as this may cause infection to occur. In this case, the blood test should be done to see if the total white blood cell count and neutrophil fraction are elevated. If they are elevated, oral amoxicillin capsules or roxithromycin capsules should be combined for antibacterial and anti-infective treatment. It is also necessary to apply topical Ravnol solution twice a day for 20 minutes and then apply mupirocin ointment twice a day afterwards for treatment. If the redness and swelling subsides, and only a pimple-like rash appears, you can apply topical Denide ointment or mometasone furoate cream, and take oral levocetirizine hydrochloride capsules or chlorpheniramine maleate tablets for anti-allergy and anti-itch treatment.
