The redness and swelling caused after ant bite is mainly treated with anti-allergic treatment. It is recommended to take oral anti-allergic drugs such as paracetamol, cetirizine, imipramine tablets, loratadine tablets, etc. Choose 1-2 kinds. As ant acid and histamine of ants can cause strong allergic reactions, such as the poor effect of anti-allergic drugs alone, it is recommended to inject paracetamol or dexamethasone injection intramuscularly, and dexamethasone injection 5mg is sufficient. Patients who have the condition are recommended to combine with oral compound glycopyrrolate tablets, which can shorten the course of treatment and improve the efficacy. For local treatment, it is recommended to first rinse with saline, disinfect with iodophor, and apply topical dexedrine cream or hydrocortisone butyrate cream twice a day. Minimize scratching, keep the area dry and clean, do not use hot water to scald, and drink less alcohol during the period.
