ADVERSE EFFECTS
Does PDT have any complications or side effects?
Porfimer sodium makes the skin and eyes sensitive to light for approximately 4 weeks after treatment. Thus, patients are advised to avoid direct sunlight and bright indoor light for at least 4 weeks.
Photo-sensitizers tend to build up in tumors and the activating light is focused on the tumor. As a result, damage to healthy tissue is minimal. However, PDT can cause burns, swelling, pain, and scarring in nearby healthy tissue. Other side effects of PDT are related to the area that is treated. They can include coughing, trouble swallowing, stomach pain, painful breathing, or shortness of breath; these side effects are usually temporary.
