Lucentis 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 certain types of eye disorders, new blood vessels grow under the retina where they leak blood and fluid.

Lucentis is used to treat the "wet form" of age-related macular degeneration.

Lucentis is also used to treat swelling in the retina caused by diabetes or by a blockage in the blood vessels.

You should not receive Lucentis if you are allergic to ranibizumab, or if you have any type of infection in or around your eyes.

Before you receive Lucentis, tell your doctor if you have glaucoma, or a history of blood clots or stroke.

Call your doctor at once if you have sudden vision problems, eye pain or irritation, discharge or bleeding from the eye, swelling around your eye, seeing flashes of light or "floaters" in your vision, sudden numbness or weakness in your body, sudden severe headache, or problems with speech or balance.

The timing of your monthly injections is very important for this medication to be effective. Call your doctor for instructions if you miss an appointment to receive your Lucentis injection.

Lucentis is given as an injection into your eye. Your doctor will use a medicine to numb your eye before giving you the injection. You will receive this injection in your doctor's office or other clinic setting.

For a short time after your injection, your eyes will be checked periodically to make sure the injection has not caused any side effects.

Lucentis is usually given once every month.

For people with macular degeneration: After you have received the first 3 or 4 injections, your doctor may change your injection schedule to once every 3 months.
