Oral anti-inflammatory medication is needed to prevent infection after ear piercing. Generally, it is to prevent Staphylococcus aureus infection, and patients can take oral cephalosporins as well as penicillins, such as cefixime, cefaclor, cefuroxime, amoxicillin, cefdinir, penicillin V potassium tablets, etc. If cephalosporin allergy is present, then oral macrolides such as roxithromycin, azithromycin, erythromycin, and levofloxacin tablets can be administered for treatment. Patients should ideally be able to disinfect locally with alcohol or iodine volts 1-2 times, usually for 3 days, but after 3 days if local swelling and congestion of the earlobe is found to be more pronounced and there is local pain, then a bacterial infection is considered. Patients need to go to the hospital to check the local area of the ear. If there is abscess formation, it is necessary to cut and drain the pus, and change the local medication twice a day, and not to wear earrings.
