Home phototherapy
Treating psoriasis with a UVB light unit at home can be an economical, convenient choice. Home UVB can be quite effective in controlling psoriasis, but it requires a very consistent treatment schedule. Patients are usually treated initially at a medical facility and eventually begin using a light box at home. However, all phototherapy requires a prescription.
A dermatologist experienced in home phototherapy will provide instruction for the schedule you should follow. How long you should expose your skin to the ultraviolet light will depend on your skin type (see chart), the type of UVB device and the intensity of light emitted from the home UVB lamps.
Just as with office-based phototherapy, people should take care to protect their eyes and other sensitive areas. Goggles, wrap-around UV-opaque glasses or coated lenses must be worn whenever you expose your eyes to the light. Men should shield their genitals with clothing or sunscreen (click here for more details). Your doctor will be able to provide guidance in this area.
The most important rule in using home phototherapy as a treatment for psoriasis is to follow your doctor's instructions and continue with regular check-ups. Home phototherapy is a medical treatment and requires monitoring by a medical professional.
Choosing a unit
More detailed information about the types of home phototherapy units available can be obtained from the treatment guide home phototherapy equipment listings or by talking with your dermatologist.
Here are a few important tips to keep in mind when choosing a unit:
- Look for safety features in home UVB equipment, such as key switches or disabling keys, that render the unit inoperative when the owner is not around.
- Make sure the unit has a reliable timer.
- Check for safety guards or grids over the lamps.
- Evaluate the durability and stability of the equipment.
- Ask whether the price includes shipping and/or assembly charges.
- Find out if the company sells replacement lamps, and the cost.
Some insurance companies will pay a percentage of the cost of home UVB equipment. A call to your health insurance company prior to purchase is worthwhile. Home UVB equipment is usually covered as durable medical equipment.
