Important safety information:
- Photofrin will make your eyes and skin extremely sensitive to sunlight and intense indoor light (eg, dental lamps, unshaded light bulbs) for at least 30 days. Sensitivity may last up to 90 days or more after treatment. For at least 30 days after receiving Photofrin and laser light treatment, it is important to protect your eyes and skin from exposure to sunlight or brightly focused indoor light. Do not avoid all indoor light, just intense light. Sunscreens, even those with high SPF factors, will not provide adequate protection from sunlight. After 30 days, expose a small area of skin to the sun for 10 minutes. If your skin turns red, swells, or blisters within 24 hours after exposure to sunlight, avoid the sun for 2 weeks before retesting. The tissue around the eyes may be very sensitive; do not use the face for testing. If you travel to an area that has stronger sunlight, test your skin before exposure to the stronger sunlight. Discuss any questions or concerns with your doctor.
- Do not use heating pads while being treated with Photofrin. Applying heat may cause skin redness and blistering.
- Sunlight, bright lights, and car headlights may cause eye discomfort while you are taking Photofrin. Wear dark sunglasses outdoors for at least 30 days and until eye sensitivity resolves after receiving Photofrin.
- If nausea, loss of appetite, vomiting, or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions on how to lessen these effects.
- Lab tests, including biopsies of treated tissues, may be performed while you use Photofrin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
