Brand Names: Macugen
What is Macugen?
Macugen (pegaptanib) is made from a human antibody fragment. It works by keeping new blood vessels from forming under the retina (a sensory membrane that lines the inside of the eye). In people with a certain type of eye disease, new blood vessels grow under the retina where they leak blood and fluid. This is known as the "wet form" of macular degeneration.
Macugen is used to treat wet age-related macular degeneration.
Macugen may also be used for purposes not listed in this medication guide.
You should not receive Macugen if you are allergic to pegaptanib, or if you have cataracts or glaucoma, or any type of bacterial, fungal, or viral infection in or around your eyes. Call your doctor at once if you have eye pain or redness, swelling or puffiness around your eyes, or sudden vision problems at any time during treatment.
Before taking this medicine
You should not receive Macugen if you are allergic to pegaptanib, or if you have any type of bacterial, fungal, or viral infection in or around your eyes.
