Does narrowband UVB phototherapy help with itchy skin?

The treatment delivers a carefully controlled band of ultraviolet B light to affected skin. For some inflammatory conditions, repeated sessions can quiet immune activity in the skin, which may ease itching as the underlying flare settles. It does not treat every cause of itch; infections, medication reactions, dry skin, nerve-related itch, and internal illnesses may need different care. Response is gradual, and the treatment area, skin tone, medicines, and previous light exposure all affect the plan.

Arrange a skin assessment before starting, especially if the itch is new, widespread, or unexplained. Tell the clinician about light sensitivity, previous skin cancers, medicines, supplements, and products that have caused reactions. Attend only the prescribed sessions, protect untreated skin as instructed, and use the moisturiser recommended for your skin. Report increasing redness, tenderness, blistering, or a new rash after a session so the dose can be reviewed.

Seek urgent medical help for itch with facial swelling, breathing difficulty, faintness, or rapidly spreading hives. Contact a clinician promptly if the skin becomes painful, blistered, infected-looking, or involved around the eyes, or if severe itch prevents sleep and daily activities. These features need assessment rather than assuming light therapy is appropriate.

What is causing my itch, and is narrowband UVB suitable for that cause? Which areas will be treated, how will my dose be adjusted, and what reactions should I report? Could any of my medicines increase sensitivity to light?
