Tyrvaya Nasal Spray for Dry Eye: Does It Actually Work?

When you think of dry eye treatment, you probably think of… eye drops.

But Tyrvaya takes a completely different approach.

It’s a nasal spray—not a drop—and it works by stimulating your body’s natural tear production through a reflex pathway.

So how does that actually work? And who is it for?

Let’s break it down.

What is Tyrvaya?

Tyrvaya (varenicline solution) nasal spray is an FDA-approved prescription treatment for dry eye disease.

Instead of being applied to the eyes, it’s sprayed into the nose—where it activates a nerve pathway connected to tear production.

How Tyrvaya works

Tyrvaya targets something called the nasal–lacrimal reflex.

Here’s what that means:

• The inside of your nose contains nerve endings connected to your tear glands
• When stimulated, those nerves signal your eyes to produce tears
• Tyrvaya activates this pathway using varenicline, a nicotinic receptor agonist

In simple terms:
👉 Spray in the nose → stimulate the nerve → increase natural tear production

What makes Tyrvaya different?

Most dry eye treatments fall into two categories:

• Add moisture (artificial tears)
• Reduce inflammation (like cyclosporine or lifitegrast)

Tyrvaya does neither directly.

👉 It works by triggering your body to make more of its own tears

No drops. No direct contact with the eye.

How to use Tyrvaya

Typical dosing:

• 1 spray in each nostril, twice daily

A few tips:

• Prime the spray if needed (per instructions)
• Do not inhale deeply while spraying—just a gentle spray is enough
• Use consistently for best results

How long does Tyrvaya take to work?

Some patients notice effects fairly quickly.

What to expect:

Early on:

• Tear production may increase shortly after use

First few weeks:

• More consistent moisture
• Reduced dryness symptoms

Longer-term:

• Continued benefit with regular use

👉 Because it stimulates a reflex, some effects can happen relatively quickly, though results vary.

What do clinical trials show?

Clinical studies of Tyrvaya found:

• Increased tear production (measured by Schirmer test)
• Improvement in dry eye symptoms for some patients

As with most treatments, response varies—but the mechanism is well established and measurable.

Common side effects

The most notable side effect is also the most talked about:

Sneezing

• Occurs in a large percentage of patients
• Usually happens right after spraying
• Often mild and short-lived

Other possible side effects:

• Cough
• Throat irritation
• Nasal discomfort

👉 Importantly: side effects are generally non-ocular (not in the eye itself)

Who may benefit from Tyrvaya

Tyrvaya may be a good option if:

• You prefer not to use eye drops
• You have reduced tear production
• You want to stimulate natural tears, not just supplement them
• You haven’t responded fully to other treatments

It may be especially helpful for patients with aqueous-deficient dry eye.

What Tyrvaya does—and doesn’t do

Tyrvaya helps:

• Stimulate natural tear production
• Increase moisture without eye drops
• Activate a natural reflex pathway

Tyrvaya doesn’t:

• Directly treat inflammation
• Address tear evaporation (oil layer issues)
• Replace a full dry eye routine

How it compares to other treatments

• Vs. Restasis/Xiidra:
  Targets tear production reflex vs inflammation
• Vs. Miebo:
  Stimulates tear production vs preventing evaporation

👉 Different tools for different root causes

The bottom line

Tyrvaya is one of the most unique dry eye treatments available.

• Delivered as a nasal spray
• Works through a nerve reflex, not the eye surface
• Designed to increase natural tear production

For the right patient, it offers a completely different way to approach dry eye.

A note from us

At Peeq, we’re not medical providers—but we believe understanding your treatment matters.

Dry eye is complex. While treatments like Tyrvaya can help stimulate tear production, long-term comfort often comes from addressing multiple factors—like tear quality, gland health, and daily habits.
