Precautions
Before using porfimer sodium, tell your doctor or pharmacist if you are allergic to it; or to certain natural pigments (porphyrins); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: a certain blood disorder (porphyria), certain esophagus problems (tracheoesophageal/bronchoesophageal fistula, esophageal varices, esophageal ulcers), a certain stomach problem (gastric varices). Before using this medication, tell your doctor or pharmacist your medical history, especially: radiation treatment. This medication will make your eyes and skin more sensitive to the sun and bright indoor light (e.g., unshaded light bulbs, dental lamps) for at least 30 days. Some patients have been sensitive to light for 90 days or more. Avoid direct sun exposure, tanning booths, and sunlamps. Wear protective clothing and dark sunglasses when outdoors. Sunscreens will not protect your skin from this type of sun sensitivity. Consult your doctor or pharmacist for more details, and report any light sensitivity reactions (e.g., blistered/red/swollen skin). Also, talk with your doctor about how and when to test whether your skin is still sensitive to the sun or bright light. Exposure of the skin to normal indoor lighting will help to decrease the amount of active drug in the skin. Therefore, do not avoid indoor lighting, and expose your skin to this type of light. This medication is not recommended for use during pregnancy. Consult your doctor for more details and to discuss using at least 2 reliable forms of birth control (e.g., condoms, birth control pills) while taking this medication. If you become pregnant or think you may be pregnant, tell your doctor immediately. It is not known whether this drug passes into breast milk. Because of the possible risk to the infant, breast-feeding while using this drug is not recommended. Consult your doctor before breast-feeding.
