Have you ever felt a gritty, burning sensation in your eyes, as if a tiny piece of sand is stuck underneath your eyelid? Maybe your eyes turn red and irritated by the end of a long day staring at your computer screen.
This common condition is known medically as dry eye disease. It can be triggered by long hours of screen time, certain health conditions, aging, and many other environmental factors.
Today, we are going to look at an exciting modern treatment option prescribed by doctors: a nasal spray. The unique part about this medicine is that you spray it into your nose rather than putting drops directly into your eyes.
Key Takeaways
- Varenicline nasal spray is a prescription treatment designed specifically for dry eye disease.
- Instead of artificial teardrops, it stimulates your body's own nervous system to produce natural tears.
- Always follow your doctor's exact instructions and read the package insert carefully before use.
- Common mild side effects include temporary sneezing, coughing, or minor nasal irritation.
- Discard the spray bottle 30 days after opening or once it reaches its expiration date.

What Is Varenicline Nasal Spray?
Simply put, this is a medicine used to treat dry eye disease. You may find it available on the market under the brand name Tyrvaya.
The most surprising thing about this treatment is that you spray it into your nose instead of placing drops into your eyes. You might wonder how a nasal spray could possibly help your eyes feel better.
Here is how it works: inside your nose, there is a special nerve that connects directly to the tear glands around your eyes. When you spray Varenicline into your nostrils, it gently stimulates that nerve.
This stimulation tells your body to produce more natural tears on its own. Instead of relying on artificial tears, your eyes are kept moist by your body's own natural moisture.
Things to Tell Your Doctor Before Using This Medicine
Before you start using this nasal spray, you must discuss several important health details with your doctor to ensure your complete safety.
Make sure to mention if you have any allergies. Tell your doctor if you have ever had an allergic reaction to Varenicline, any other medicines, foods, or preservatives.
If you are pregnant, planning to become pregnant soon, or currently breastfeeding a baby, you must inform your doctor right away.
How to Use This Medicine Correctly
Because this is a nasal spray, knowing the correct technique is essential for getting the best results from your treatment.
Always follow your doctor's exact instructions for how often and when to use the spray. If you are told to use it twice a day, try to stick to the exact same times every day. Never use more than the prescribed amount.
Read the step-by-step instructions for use that come inside the medicine box. The leaflet will explain how to prime the spray bottle before your first use and how to hold it at the correct angle inside your nose. If anything is unclear, ask your doctor or pharmacist to show you.
If you are considering giving this medicine to a child, you must consult your pediatrician first, as special safety precautions apply.
What Happens If You Use Too Much? (Overdose)
If you accidentally use more of this nasal spray than prescribed, stay calm but take action quickly. Contact your local emergency services or go to the nearest hospital emergency room right away. Never ignore an accidental overdose.
What to Do If You Miss a Dose
If you forget to use your nasal spray at the scheduled time, do not panic. Simply skip the missed dose entirely.
Take your next dose at your usual scheduled time. Never take two doses at the same time to make up for a forgotten one.
