Izervay (avacincaptad pegol) is a prescription drug that’s used to treat an eye condition called geographic atrophy due to age-related macular degeneration. The drug is given as an injection into your eye.

Izervay basics

Izervay is a brand-name medication. It contains the active ingredient avacincaptad pegol. (An active ingredient is what makes a drug work.)

There are currently no generic versions of Izervay.

Izervay is used in adults to treat geographic atrophy due to age-related macular degeneration (AMD).

With AMD, factors related to aging cause damage to your retina (the light-detecting tissue in your eye). This condition usually gets worse over time, resulting in vision problems.

Izervay treats geographic atrophy, which is the most advanced stage of AMD. With geographic atrophy, some parts of your retina waste away, leading to loss of central vision. (Central vision refers to the ability to see objects directly in front of you.)

An overactive immune system is believed to play a role in retina damage from AMD. Izervay works by blocking certain proteins involved in the immune system. The goal of Izervay treatment is to slow the worsening of retina damage. However, Izervay doesn’t reverse the damage you already have.

Your eye doctor can help determine whether Izervay may be a fit for you.

Like most drugs, Izervay may cause mild or serious side effects. The lists below describe some of the more common side effects that Izervay may cause. These lists don’t include all possible side effects.

Combining a drug with certain other medications, vaccines, foods, and other things can affect how the drug works. These effects are called interactions.

The main difference between these drugs is their dosing schedule. Izervay injections are given once per month, while Syfovre injections are given once every 25–60 days.

Is Izervay used for cataracts?

No, Izervay is not used to treat cataracts. Izervay is prescribed to treat geographic atrophy due to age-related macular degeneration (AMD) in adults.

Cataracts occur when the lens of your eye becomes cloudy, leading to blurry vision. Currently, there are no prescription eyedrops or injections approved to treat cataracts. Surgery is an option to replace the cloudy lens with a clear, artificial lens.

To learn more about treatment options for cataracts, such as cataract surgery, talk with your doctor.
