The redness, pain and hardness of facial insect bites indicate that the inflammatory infection is more obvious. It is necessary to conduct routine blood tests, C-reactive protein and blood sedimentation. If the total white blood cell count, C-reactive protein and blood sedimentation of routine blood infection indicators are elevated, it indicates that the inflammation is more serious. Oral penicillin V potassium tablets or roxithromycin capsules can be taken, together with topical application of clindamycin phosphate gel and compound polymyxin B ointment to provide anti-inflammatory and pain-relieving therapeutic effects. Anti-allergic treatment is also needed. You can take oral levocetirizine hydrochloride oral solution and desloratadine dry suspension with compound glycyrrhizin capsules, and for obvious redness and swelling, you can add erdin capsules to clear the fire and detoxify the toxin.
