Cheilitis is a localized inflammation of the lips. When a patient has cheilitis, applying erythromycin ointment locally can effectively alleviate some inflammatory symptoms on the lips, reducing congestion, swelling, pain, or peeling and bleeding, and can aid in healing. Additionally, patients should pay attention to their diet when experiencing cheilitis by eating light, including fresh vegetables, fruits, grains, and high-quality proteins, as a comprehensive diet can provide essential nutrients and help in the healing of cheilitis. Furthermore, patients should avoid touching their lips frequently with their hands to prevent worsening the inflammation or causing an infection.
