What is the most important information I should know about porfimer?
Porfimer should only be administered under the supervision of a qualified healthcare provider
experienced in the use of cancer chemotherapeutic agents.
After
porfimer has been administered, exposure to sunlight or bright indoor light
(
examination lamps, dental lights,
operating room lamps, tanning beds, or very close unshaded light
bulbs) must be avoided for at least 30 days. Sensitivity may last for 90 days or more. Exposure to
normal indoor light is good, as this helps the body to eliminate porfimer. Therefore, do not stay in
darkened rooms. Before exposing any area of skin to direct sunlight or bright indoor light, test for
sensitivity by exposing a small area of skin to sunlight for 10 minutes. If there is no reaction (such as
redness, blistering or swelling) within 24 hours, you can gradually increase your sun exposure time. If a
reaction does occur, wait another 2 weeks before testing again. Do not use the face or skin around the
eyes as a test area. If you travel to a place that has more sunlight, you should retest with the 10 minute
exposure procedure. Sun
screens will not prevent a reaction. Sun screens stop UV (invisible) light,
while porfimer makes the skin sensitive to visible light
Porfimer may increase the sensitivity of the eyes to sun, bright lights, or car headlights. Dark
sunglasses which have an average white light transmittance of less than 4% should be worn when
outdoors for 30 days following treatment with porfimer.
