Because of the possibilities of ocular damage, aging of the skin, and skin cancer (including melanoma), the patient should be fully informed by the physician of the risks inherent in this therapy.

Methoxsalenbelongs to the group of medicines called psoralens. It is used along with ultraviolet light (found in sunlight and some special lamps) to treat the white blood cells from your blood in a process called photopheresis. The treated white blood cells are returned to your body to control skin problems associated with cutaneous T-cell lymphoma, a cancer of the lymph system.
Methoxsalen is to be administered only by or under the supervision of your doctor or other health care professional.

Eating certain foods while you are receiving methoxsalen treatment may increase your skin's sensitivity to sunlight. To help prevent this, avoid eating limes, figs, parsley, parsnips, mustard, carrots, and celery while you are being treated with this medicine.
Your doctor should check your progress at regular visits to make sure this treatment is working and that it does not cause unwanted effects. You also should have regular eye examinations.
This medicine increases the sensitivity of your skin to sunlight and also may cause premature aging of the skin. Therefore, exposure to the sun, even through window glass or on a cloudy day, could cause a serious burn. If you must go out during the daylight hours:
For 24 hours after your methoxsalen treatment, your eyes should be protected during daylight hours with special wraparound sunglasses that totally block or absorb ultraviolet light (ordinary sunglasses are not adequate). This is to prevent cataracts. Your doctor will tell you what kind of sunglasses to use. These glasses should be worn even in indirect light, such as light coming through a window, or on a cloudy day.

Premature aging of the skin may occur as a result of prolonged methoxsalen therapy. This effect is permanent and is similar to what happens when a person sunbathes for long periods of time.
