Does narrowband UVB phototherapy treat atopic dermatitis?

Atopic dermatitis is an inflammatory condition that can cause itch, dryness, redness, and recurrent flares. Narrowband UVB is a supervised light treatment intended to reduce inflammatory activity across affected skin. It may be discussed when moisturising, trigger avoidance, and prescribed topical treatment have not provided enough control, or when another treatment is unsuitable. It is not a cure and does not repair the skin barrier on its own. The decision depends on the extent and location of eczema, skin sensitivity, medicines, and previous reactions to light.

Keep using the eczema plan provided by your clinician, including regular emollient application, unless you are told to change it. Give the phototherapy team a complete medicine and supplement list, and mention cold sores, light sensitivity, or a history of skin cancer. Protect the eyes as directed and avoid extra ultraviolet exposure. Record worsening itch, burning, persistent redness, or blistering after sessions so the team can adjust or stop treatment when needed.

Get prompt care if eczema becomes painful, rapidly worsens, leaks fluid, develops yellow crusts, or is accompanied by fever, because infection may need treatment. Urgent help is needed for facial swelling, breathing difficulty, or a widespread blistering rash. A flare that affects sleep, eating, work, or a child’s behaviour should be reviewed rather than managed by increasing light exposure yourself.

How active is my atopic dermatitis, and why would light treatment fit my plan? Which moisturisers and medicines should continue? How will dose and response be monitored, and what should I do after a missed session?
