Oxsoralen (Methoxsalen) belongs to the group of medicines called psoralens. Oxsoralen (Methoxsalen) is used along with ultraviolet light (found in sunlight and some special lamps) in a treatment called PUVA to treat vitiligo, a disease in which skin color is lost, and psoriasis, a skin condition associated with red and scaly patches.
Oxsoralen (Methoxsalen) is also used with ultraviolet light in the treatment of white blood cells. This treatment is called photopheresis and is used to treat the skin problems associated with mycosis fungoides, which is a type of lymphoma.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if you think you have taken an overdose or if any of the following side effects occur, since they may indicate a serious burn:
Blistering and peeling of skin; reddened, sore skin; swelling (especially of feet or lower legs).
Other side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. These include itching of skin, nausea, dizziness, mental depression, nervousness and/or trouble sleeping.
