What should you know about infective cheilitis?

Cheilitis means inflamed lips; the infective form can involve bacteria, viruses, or yeast. It may affect one area or both lips and can cause fissures at the corners, burning, tenderness, scale, blisters, or yellow crust. Moisture, lip licking, damaged skin, dental appliances, and an underlying skin condition can make the barrier easier to disrupt. A clinician may ask about new products, oral symptoms, medicines, and recent injury before choosing treatment.

Rinse gently, pat dry, and apply a bland protective ointment if it does not sting. Stop fragranced balms, exfoliants, and products that trigger burning. Do not lick or peel the lips, and avoid sharing drinks or lip products. An emollient can support the damaged barrier; a topical corticosteroid may be considered for inflammation in selected cases, but it should not be used on a suspected infection unless a clinician advises it. Treatment must match the organism and site.

Seek prompt medical care for rapidly spreading redness, increasing swelling, pus, fever, severe pain, or sores inside the mouth. Get urgent help for tongue or throat swelling, breathing difficulty, or trouble swallowing. Arrange review if the problem keeps returning, does not improve, or makes eating and drinking difficult.

Ask which type of infection is suspected, whether a swab or dental assessment is useful, whether an emollient is suitable, and when anti-inflammatory treatment is safe.
