Can erythromycin ointment be applied to red and swollen ears?

Generally speaking, red and swollen ears can usually be treated with erythromycin ointment in most cases. The specific analysis is as follows:

Redness and swelling of the ear may be caused by various factors, such as external ear canal infections, allergic reactions, or skin conditions. Erythromycin ointment is a topical antibiotic containing erythromycin, which has anti-inflammatory and antibacterial properties. It is suitable for treating and preventing skin infections, including impetigo and other pyogenic skin diseases, minor burns, infected ulcerated surfaces, and common acne.

Erythromycin ointment can be applied for ordinary cases of ear redness and swelling, as it helps reduce inflammation and fight bacterial infection, thereby alleviating symptoms. However, if there is significant pus or discharge inside the ear, or if a boil has already ruptured, applying erythromycin ointment may not be appropriate. Erythromycin ointment might hinder the drainage of secretions and delay recovery from inflammation. In such cases, it is recommended to first seek medical treatment at a hospital for proper cleaning before considering the use of erythromycin ointment.

In daily life, individuals should always consult a doctor or licensed pharmacist before using any medication to avoid self-medication and ensure the safe and effective use of drugs.
