Proper Use
A nurse or other trained health professional will give you this medicine. This medicine is given through a needle placed in one of your veins.
Treatment with porfimer and laser light occurs in three steps. First, the porfimer is injected into your body. Second, about 2 days later, a laser light is directed at the cancer. Then, about 2 or 3 days after the light is applied, your doctor will remove the cancer cells that have been destroyed.
