When are oral antibiotics recommended for acne keloidalis nuchae?

Acne keloidalis nuchae affects hair follicles at the back of the neck and scalp margin. Repeated inflammation can lead to firm bumps, crusting, drainage, and raised scars. An antibiotic may calm inflammation or treat suspected bacterial involvement, but it does not remove established scar tissue or correct shaving and friction triggers. A dermatologist may combine medical treatment with topical care, scar treatment, or hair-removal advice.

Use the medicine exactly as prescribed and complete the planned course unless the prescriber changes it. Avoid close shaving, tight collars, scratching, and picking. Keep the area clean with gentle products and tell the clinician about stomach upset, rash, severe diarrhoea, or other new symptoms. Do not share leftover antibiotics or use them for a new flare without review.

Arrange prompt dermatology care if pain, warmth, pus, swelling, or redness is increasing, or if hair loss and scarring are progressing. Seek urgent help for fever with rapidly spreading redness, facial swelling, or feeling seriously unwell. A non-healing or bleeding bump also needs examination rather than repeated self-treatment.

Ask whether infection or follicle inflammation is driving the flare, how long treatment should continue, which hair and skin-care changes matter most, and how existing scars can be managed.
