What is ranibizumab?

Ranibizumab is used in adults to treat specific eye issues. It can be given as an injection or as an eye implant.

Ranibizumab may be used to treat wet age-related macular degeneration, swelling in the retina, eye issues caused by diabetes, or nearsightedness due to abnormal blood vessel growth in the eye.

The eye implant is only for certain eye problems in people who have previously responded to similar eye injections.

Ranibizumab may also be used for other reasons not mentioned in this medication guide.

This section was rewritten for readability and reviewed for meaning.

How is ranibizumab given?

Follow all directions on your prescription label and read all medication guides or instruction sheets.

Ranibizumab injection is given as an injection into the eye. Your doctor will use a numbing medicine on your eye before the injection. You will receive this injection in your doctor's office or another clinical setting.

Ranibizumab eye implant is placed through the white part of the eye by your healthcare provider. Your implant may need to be refilled about every 6 to 9 months, depending on the condition being treated.

Tell your doctor that you have a ranibizumab eye implant before having an MRI or any procedure on your eye.

Your eyes will be checked to ensure ranibizumab has not caused any serious side effects.

Call your doctor right away if you notice the eye implant has moved out of place.

Wash your hands first if you need to rub your eyes or touch the area where the eye implant is located.
