Types of Ultraviolet Light Treatments
Ultraviolet B light is usually our first line of light treatment. We administer two types of ultraviolet B light - Broad Band (BB) and Narrow Band (NB). PUVA
is our third available treatment choice. It consists of the ingestion
of an oral medication (Psoralen) followed by the administration of UVA (sun tanning)
light rays, hence the name PUVA. The psoralen becomes deposited in the
skin and is activated by the UVA light that is administered 1 - 2 hours
later. Treatments are initially given 2-3 times per week and are tapered
upon remission, usually after 20-25 treatments. Localized
psoriasis of the palms and soles is a difficult therapeutic problem as
it often does not respond well to topical medications. The administration of psoralen, usually by ingestion but occasionally by topical
absorption through the application of an ointment or a 15 minute soak, followed by
UVA light exposure, can prove to be helpful in many instances.
*Any of these
treatments can be, and often are administered in combination with topical
medications, such as corticosteroid vitamin D (Dovonex) or retinoid
(Tazorac) preparations and/or oral medications, such as retinoids (Soriatane), methotrexate, "biologic" drugs
(Enbrel, Amevive, and others) and cyclosporine.
