Can erythromycin eye ointment be applied to the lips?

Generally, if a patient has lip dermatosis, erythromycin eye ointment can be applied to the lips as directed by a physician. However, if the dermatosis is not related to the lips or eyes, using erythromycin eye ointment is usually not recommended. Detailed explanations are as follows:

The main ingredient of erythromycin eye ointment is erythromycin, a macrolide antibiotic that can be used to treat ocular infections such as trachoma, conjunctivitis, and blepharitis, exerting antibacterial and anti-inflammatory effects. If a patient has lip dermatosis, such as papules or pustules, erythromycin eye ointment can be applied to the lips under medical guidance. Additionally, erythromycin eye ointment can moisturize, protect, and aid in the repair of lip mucosa. The erythromycin component can also help prevent infection.

However, if the skin condition does not involve the eyes or lips, erythromycin eye ointment is generally not recommended, as it may have limited therapeutic effects and could potentially worsen symptoms. If the lips are dry and peeling, applying erythromycin eye ointment locally may provide moisturizing and protective effects.

Before using erythromycin eye ointment, consult a healthcare professional. Ensure the lip area is thoroughly clean before application to avoid worsening infection. Follow medical instructions carefully and avoid self-medicating or overusing the ointment to prevent unnecessary harm to the body.
