What is narrowband UVB?
Ultraviolet radiation from artificial light sources have been used by dermatologists for over 100 years and is a widely used and effective for treating a number of skin conditions.
Choice of UVB over other forms of light treatment depends on a wide range of factors including age, disease, skin type, previous therapy, current medication.
In Newcastle we use narrowband UVB (TL01) which is often more effective than conventional broadband UVB in the treatment of psoriasis and possibly other skin diseases too. We may therefore recommend it even if previous conventional (broadband) UVB treatments have been disappointing.
What is the aim of treatment?
The aim of the treatment is to clear your skin, although it will not be effective for everybody. It is difficult to know how long your skin will remain clear for after treatment, but it is likely that you will require further treatment in the future.
Most patients are not routinely followed up after successful treatment, but you can ask your GP to refer you back if further treatment is required.
Are there any risks?
The most common side effect of this treatment is erythema/sunburn-like reaction to exposed skin. If this occurs you must inform the phototherapy team prior to your next treatment.
Other potential short term side effects include
- Cold sores (if you are prone to these, cover the area affected with sun block before you have ultraviolet treatment).
- Polymorphic light eruption (a usually itchy spotty reaction appearing within a few hours to a day following treatment).
- Blistering within areas of psoriasis.
- Worsening of skin disease.
- Dry/ itchy skin.
- Tanning – is an increase in pigmentation to the treated area.
Please inform the phototherapy nurse prior to your treatment if you experience any side effects.
Longer-term side effects of repeated courses of UVB include skin ageing and potentially skin cancer. Skin cancer risk is related to total lifetime exposure to ultraviolet light, as well as other factors such as how easily you burn. However, narrowband UVB is safer than PUVA (an alternative form of phototherapy involving a Psoralen and ultraviolet A).
Do
- Bring your own clothing if you do not wish to wear the hospital gowns.
- Moisturise your skin at least 3 times per day. Dry flaky skin will deflect the light, rendering UVB therapy ineffective. You can moisturise your skin up to 2 hours before your exposure to light.
- Use your prescribed steroid ointment/other topical treatment every evening as necessary.
- Inform the doctor or nurse if you are taking, or about to start any new medications including herbal medications (prescribed or otherwise) or cream while having UV therapy.
- On bright days, protect treated areas from the sunlight, by wearing long sleeves, a hat etc. Sun block (SPF 30) can be used after treatment or on non-treatment days.
- Wear clothing/underwear and jewellery e.g. rings; if you wear these at the start of treatment. You should wear these at every treatment thereafter. Areas covered at the start will cause a sunburn reaction if subsequently exposed.
- Make sure you attend all appointments to maximise the benefits of UVB.
Don’t
- Use moisturiser and make up that contains SPF unless directed otherwise by the phototherapy team.
- Wear fragrances and sunblock before treatment unless you have been told otherwise.
- Use sunbeds and keep sunlight exposure to a minimum during your course of treatment as this may cause erythema (sunburn).
Your treatment
The unit is open Monday to Friday between 7.30am and 4.45pm.
Following your consultation with the doctor in the phototherapy clinic, your named nurse will discuss your appointment and treatment procedure with you.
Please make sure to attend your appointments at the times and dates scheduled.
Treatment is given either twice a week on a Tuesday and Thursday, or three times a week on a Monday, Wednesday and Friday.
Appointments are given on a block booking basis. A course of treatment will last up to 8-12 weeks (24-30 treatments).
At the first visit an arm test may be performed on small patches of normal skin on your arm. This is read 24 hours later and tells us how sensitive your skin is to the treatment.
This allows us to choose a safe but effective dose of UVB to start the course of treatment. At subsequent visits the increase in dose depends on disease and skin response (or lack of response) after the previous treatments. Treatment is given as a prescribed dose of J/cm2.
Ideally you will develop mild skin redness/pinkness with no discomfort after each treatment.
Please tell the phototherapy nurse prior to your treatment if your skin becomes sore or uncomfortable.
All treatments are nurse supervised and given in stand up cabinets surrounded by fluorescent lamps.
Goggles must be worn at all times unless specified by the prescribing doctor.
Men should avoid exposing the skin of the penis and scrotum to ultraviolet light. To allow treatment to your thighs/ buttocks, it is best for men to wear a jockstrap or a black sock to protect the genital area during treatment. More information is available from nursing staff.
UVB is safe to use in pregnancy.
