Topical application of erythromycin ointment for folliculitis can usually cure in 7-10 days. Folliculitis is usually an inflammation caused by bacterial infection after hair follicle blockage. The common causative organism is Staphylococcus aureus, and a few folliculitis are caused by fungal infection. Erythromycin ointment is a macrolide antibiotic ointment that can treat folliculitis due to bacterial infection. A single episode of folliculitis can be cured with topical medication for about 7-10 days. If folliculitis worsens and a localized abscess forms, the abscess should be incised to drain the pus, the medication should be changed regularly, and oral antibiotic therapy should be administered. In addition, multiple folliculitis may also be related to diabetes, poor dietary habits, and lifestyle habits, which require comprehensive treatment. Therefore, patients are advised to work and rest regularly, eat a light diet, avoid spicy and stimulating foods, and exercise appropriately to improve resistance and reduce the incidence of folliculitis.
