PUVA is an acronym that stands for Psoralen plus ultraviolet A (UVA) therapy. It is a medical treatment used primarily for skin disorders like psoriasis, eczema, vitiligo, and other similar conditions. The therapy involves the combination of a medication known as psoralen and exposure to UVA light.
Psoralen is a photosensitizing agent that can be taken orally or applied topically, depending on the specific condition being treated. It works by making the skin more sensitive to UVA light. UVA light, on the other hand, is a specific type of ultraviolet light with a longer wavelength than UVB light.
During a PUVA treatment session, the patient takes psoralen orally or applies it to their skin a specific amount of time before being exposed to UVA light. The UVA light is provided by a specialized light booth or box. The duration of each session and the number of sessions required vary depending on the condition being treated and the individual's response to the therapy.
PUVA therapy works by suppressing the immune system and slowing down the production of skin cells. This helps to reduce the inflammation, scaling, and itching associated with skin disorders such as psoriasis. The treatment may require several weeks or months to achieve noticeable improvements in the skin condition.
It is important for patients undergoing PUVA therapy to protect their eyes and cover other sensitive body areas during the treatment as UVA light can be harmful. Regular monitoring by a healthcare professional is also necessary to evaluate the progress and adjust the treatment plan accordingly.
In conclusion, PUVA therapy is a medical treatment that combines psoralen medication with exposure to UVA light to manage various skin disorders by suppressing the immune system and slowing down the production of skin cells.
