Vyzulta (latanoprostene bunod) is a prescription drug used in adults and certain children to treat high pressure in the eye caused by open-angle glaucoma or ocular hypertension. Vyzulta comes as a liquid eye drop.

Vyzulta basics

Vyzulta contains the active ingredient latanoprostene bunod. It belongs to a group of drugs called prostaglandin analogs.

Vyzulta is a brand-name medication. A generic version of the drug isn’t currently available.

Vyzulta is used to treat increased pressure in the eye caused by open-angle glaucoma or ocular hypertension. The drug may be prescribed for adults and for children ages 17 years and older.

Your eyes are filled with a clear liquid that gives them their shape and provides nutrients to their cells. Changes in the amount of this liquid can lead to high or low pressure in your eye.

If not treated, increased eye pressure can damage your optic nerve, which carries information from your eyes to your brain. Increased eye pressure is the leading cause of glaucoma, a condition that can lead to permanent vision loss or blindness.

High eye pressure often does not cause symptoms until it has already caused advanced damage to your optic nerve. It’s typically detected during an eye exam when an eye doctor measures your eye pressure.

Glaucoma does have some possible symptoms, such as:

  • reduced vision, including loss of peripheral (side) vision
  • redness in the white of your eye
  • bulging or swelling in your cornea

Vyzulta works to treat high pressure in your eye by increasing drainage of the clear liquid from your eyes.

Like most drugs, Vyzulta may cause mild to serious side effects. The lists below contain some of the more common side effects Vyzulta may cause, but they don’t include all possible side effects.

Vyzulta comes as a liquid solution that is given as an eye drop. It’s important that you avoid touching the tip of the container with your hands or any other surface. Doing so can contaminate the dropper tip with bacteria, which can lead to a bacterial infection in your eye (called bacterial keratitis).

You should not use other eye drops at the exact same time as a dose of Vyzulta. If you use other eye drops in addition to Vyzulta, separate their doses by at least 5 minutes.

If you wear contact lenses, remove them before using Vyzulta. After using the eye drops, wait at least 15 minutes before putting your contacts back in.
