What are PUVA light therapy side effects?

PUVA has a definite potential to cause skin cancer, including melanomas. The risk of developing skin cancer is directly related to the amount of energy administered. It is well known to cause photo-aging that is unavoidable. If not appropriately monitored, PUVA can produce severe ultraviolet light burns. Occasionally, Oxsoralen can cause nausea so susceptible patients take the drug with food.

How effective is PUVA therapy?

PUVA is a safe and effective treatment for psoriasis. Recently, a newer treatment has supplanted it to some extent, utilizing a different wavelength of light called "narrow band UVB." Although a visit to a physician's office is still necessary to administer the light, it is not necessary to take a drug by mouth. Both types of treatments are similar in their effectiveness.
