Lucentis (Generic Ranibizumab Injection)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Ranibizumab is used to treat wet age-related macular degeneration (AMD; an ongoing disease of the eye that causes loss of the ability to see straight ahead and may make it more difficult to read, drive, or perform other daily activities). It is also used to treat macular edema after retinal vein occlusion (an eye disease caused by blockage of blood flow from the eye that leads to blurry vision and vision loss), diabetic macular edema (an eye disease caused by diabetes that can lead to vision loss), and diabetic retinopathy (damage to the eyes caused by diabetes). Ranibizumab is in a class of medications called vascular endothelial growth factor A (VEGF-A) antagonists. It works by stopping abnormal blood vessel growth and leakage in the eye(s) that may cause vision loss.
How should this medicine be used?
Ranibizumab comes as a solution (liquid) to be injected into the eye by a doctor. It is usually given in a doctor’s office every month. Your doctor may give you injections on a different schedule if that is best for you.
Before you receive a ranibizumab injection, your doctor will clean your eye to prevent infection and numb your eye to reduce discomfort during the injection. You may feel pressure in your eye when the medication is injected. After your injection, your doctor will need to examine your eyes before you leave the office.
Ranibizumab controls certain eye conditions, but does not cure them. Your doctor will watch you carefully to see how well ranibizumab works for you. Talk to your doctor about how long you should continue treatment with ranibizumab.
