Methoxsalen is a very strong medicine that increases the skin's sensitivity to sunlight. In addition to causing serious sunburns if not properly used, it has been reported to increase the chance of skin cancer. Also, like too much sunlight, PUVA can cause premature aging of the skin. Therefore, methoxsalen should be used only as directed and should not be used simply for suntanning. Before using this medicine, be sure that you have discussed its use with your doctor.

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people.
