As you grow older or manage conditions like diabetes, you might notice your eyesight starting to blur or change.

If you are facing these vision challenges, your eye doctor might suggest a special treatment given directly into your eye called Faricimab.

Faricimab is a modern medical breakthrough designed to protect your sight and slow down certain eye conditions. Understanding how this medicine works, what the injection process looks like, and how to care for your eyes afterward will help you feel confident and prepared for your treatment journey.

What Is Faricimab and How Does It Work?

Simply put, Faricimab is a specialized prescription medicine given as an injection directly into the eyeball to treat two major eye conditions affecting your vision. It is commonly known by its brand name, Vabysmo, though your doctor may also refer to it by its generic name, Faricimab.

The two main conditions treated with Faricimab include:

  • Wet age-related macular degeneration: This is an eye condition linked to aging where abnormal blood vessels grow under the retina, leaking fluid and causing blurry or lost central vision.
  • Diabetic macular edema: This is a complication of diabetes where high blood sugar damages retinal blood vessels, causing them to leak fluid and swell in the part of the eye responsible for sharp vision.

The primary goal of this medicine is to stop your eye condition from getting worse and help protect your current level of vision. However, you should remember that while it protects and stabilizes your sight, it does not completely cure the underlying disease.

Key Takeaways About Faricimab

  • Faricimab is an eye injection used to treat wet macular degeneration and diabetic macular edema.
  • It helps preserve your remaining vision and prevents your eye condition from worsening over time.
  • The injection must be given by a trained eye specialist in a sterile clinical or hospital environment.
  • You must strictly avoid pregnancy during treatment and for three months after your last dose.
  • Always report sudden vision changes, eye pain, or redness to your doctor right away.

Things to Tell Your Doctor Before Starting Treatment

Before you receive your first Faricimab injection, giving your doctor a complete and accurate picture of your health is essential. Sharing your full medical background helps your care team keep you safe and prevent unwanted complications.

Make sure you tell your eye specialist if any of the following apply to you:

  • You currently have an active infection in or around your eye.
  • You have any eye inflammation, swelling, or unusual eye redness.
  • You have been diagnosed with glaucoma or high pressure inside your eye.
  • You have known allergies to Faricimab, other medicines, foods, or dyes.
  • You are pregnant, planning to become pregnant, or think you might be pregnant.
  • You are currently breastfeeding your baby or plan to breastfeed.

How Is Faricimab Given?

This is not a medicine you can take at home by yourself. Faricimab is given as an intravitreal injection. This the medicine is injected straight into the jelly-like substance inside your eyeball.

This procedure is delicate and must be performed by a specially trained ophthalmologist or eye care team in a clean clinical or hospital setting. If this medicine is being considered for a child or younger patient, specialized pediatric precautions and care plans will apply.

What Happens If You Receive Too Much Medicine?

Because trained medical professionals give Faricimab in a controlled hospital setting, receiving an accidental overdose is very rare. However, if you ever suspect you received too much medicine or feel unwell, contact your local emergency services or poison control center right away.

In the United States and Canada, call 911. In the United Kingdom, call 999 or go right away to your nearest hospital Emergency Department (ER or A&E).

What Happens If You Miss a Dose?

Keeping every scheduled appointment is critical for the success of your eye treatment. Sticking to your doctor's timeline ensures steady protection for your vision.

If you miss an appointment or forget your injection date, contact your doctor's office right away. Reschedule your visit as soon as possible to keep your treatment plan on track.

Things to Watch Out For During Treatment

Taking care of your eyes during your Faricimab treatment requires a bit of extra daily attention from you. Follow these guidelines to protect your health:

  • Routine eye checks: Your doctor will test your vision and examine your eyes carefully before and after every single injection.
  • Report vision changes: If you notice any sudden changes in your sight—such as blurriness, wavy lines, or dark floating spots—tell your doctor right away.
  • Temporary blurry vision: Right after your injection, your vision may be blurry for a short time. Do not drive or operate heavy machinery until your clear vision returns.
  • Strict pregnancy prevention: This is extremely important. You must not become pregnant while receiving Faricimab. Women must use an effective birth control method during treatment and for three months after the final dose because this medicine can harm an unborn baby. Tell your doctor right away if you suspect you are pregnant.

Potential Side Effects to Know

Like all medicines, Faricimab can cause side effects, though not everyone experiences them. Some side effects require urgent medical attention. This others are milder.

This list does not cover every possible side effect. If you notice any unusual symptoms or feel that something is wrong with your eye, speak with your doctor right away.

When to Seek Emergency Medical Help
