This medicine and PUVA can increase your risk of getting skin cancer. Show your doctor or health care professional any unusual sores or blemishes that develop. If your skin gets very dry, ask your doctor or health care professional before you use any skin products.

This medicine can increase sensitivity of the skin to sun or UV light. This could lead to a serious burn. Keep out of the sun for at least 24 hours before and 48 hours after PUVA.

Do not apply sunscreen to areas of psoriasis until after light therapy. Do not use sun lamps, sun tanning beds or booths. Certain foods can increase your sensitivity to sunlight while using this medicine. Avoid eating limes, figs, parsley, parsnips, mustard, carrots, and celery while using this medicine.

You can get permanent premature aging of the skin if you use this medicine for a long time. This effect is similar to the result of too much sunbathing.
