What is narrowband UVB phototherapy, and when is it used?
Narrowband UVB is a medically supervised light treatment for selected cases of psoriasis, vitiligo, eczema and other diagnosed skin conditions. Dose and sessions are tailored to skin response. It differs from tanning beds and does not guarantee permanent cure.
Details
How is treatment planned?
The dermatology team considers the diagnosis, skin type, previous response and medicines. Doses follow a monitored protocol and may need adjustment after redness or missed sessions. Do not copy another person’s schedule or use a home device without a supervised plan.
Precautions during treatment
Follow instructions for eye protection and covering areas that do not need treatment. Report new medicines or supplements because some increase light sensitivity. Do not add tanning sessions or deliberate sun exposure to increase the dose.
Monitoring and adverse effects
Dryness, redness or burns may occur. Tell the team about pain or blistering before another session. Discuss expected benefits, possible relapse and cumulative exposure risks, particularly with previous phototherapy or skin cancer. Attendance and side-effect reporting help the team adjust treatment safely.
