Uses
This medication is used to treat a certain inherited eye condition (retinal dystrophy). Voretigene neparvovec is made from a certain virus that has been specially prepared. The virus is used to carry a certain human gene (RPE65) into cells. You will receive this treatment only after tests by your doctor have found that this gene does not work the way it should in your cells. This type of treatment is known as gene therapy. Treatment may improve symptoms of retinal dystrophy, such as decreased vision, loss of side vision, or poor vision at night.
How to use Voretigene Neparvovec-Rzyl Suspension
Your doctor may prescribe medication (such as prednisone) for you to take by mouth daily, starting 3 days before treatment to each eye, and continuing for 2 weeks after the injections. Carefully follow your doctor's directions for taking your medication(s).
This medication is prepared and given by injection into the affected eye(s) by a health care professional. Your doctor will treat each eye on separate days, at least 6 days apart. The eye is numbed before the injection. After the injection, you will remain in the doctor's office for a while, and your eye(s) and vision will be monitored.
After leaving the hospital or clinic, try to rest lying down as much as possible for 24 hours.
During your procedure, an air bubble will form in your eye. This will slowly shrink over 1 week or longer. Do not fly in an airplane, travel to high altitudes, or scuba dive until you are told the air bubble is gone. A change in altitude while the air bubble is in your eye may cause permanent vision loss.
Small amounts of virus may shed from your tears and nose for a short time after the injection. Ask your doctor how to handle and dispose of waste material from dressings, tears, and your nose for up to 7 days after the injection.
Tell your doctor if your condition does not get better or if it gets worse.
