Beyond Artificial Tears: A Patient's Guide to Prescription Dry Eye Medications
If you suffer from the gritty, burning, and irritating sensation of dry eye disease, you know it’s more than just a minor annoyance. It can significantly impact your quality of life, making reading, driving, or working on a computer a daily challenge.
While over-the-counter artificial tears are often the first step, many people find they aren’t enough to manage their symptoms. Fortunately, the field of dry eye treatment has advanced significantly, offering a range of prescription medications designed to address the underlying causes of the condition.
This guide will walk you through the different types of prescription medications your eye doctor might discuss with you.
The Foundation: Over-the-Counter (OTC) Artificial Tears
Before we dive into prescriptions, it's important to understand the role of artificial tears. They work by supplementing your natural tear film, providing lubrication and temporary relief.
Preservative vs. Preservative-Free: If you use drops more than four times a day, your doctor will likely recommend preservative-free options. Preservatives can irritate the eyes with frequent use.
Gels and Ointments: Thicker than regular drops, these are excellent for providing long-lasting relief, especially when used overnight.
If OTC options aren't cutting it, it may be time to explore prescription treatments.
Prescription Medications: Targeting the Root Causes
Prescription medications go beyond simple lubrication. They are designed to treat the underlying issues driving your dry eye, such as inflammation, poor tear production, or rapid tear evaporation.
1. Medications to Reduce Inflammation
For many people, dry eye is an inflammatory condition. Your immune system mistakenly attacks the glands that produce tears, leading to a vicious cycle of irritation and dryness. Medications that target this inflammation are a cornerstone of modern dry eye therapy.
Cyclosporine (Brand Names: Restasis®, Cequa®)
How it works: This is an immunomodulator. It works by calming the immune response on your eye's surface, which helps your body produce more of its own natural, healthy tears over time.
What to expect: This is not a quick fix. It can take 3 to 6 months of consistent use to experience the full benefits. It's designed for long-term management.
Lifitegrast (Brand Name: Xiidra®)
How it works: This medication also targets inflammation but through a different pathway. It blocks a specific protein on the cell surface that is responsible for activating the inflammatory response.
What to expect: Some patients may notice relief in as little as two weeks, though for others it may take longer. A common side effect is a temporary unusual or metallic taste after administration.
Corticosteroids (Brand Names: Lotemax®, Eysuvis®, Flarex®)
How it works: Steroid eye drops are potent anti-inflammatories. Think of them as a "fire extinguisher" for your eyes—they are excellent at quickly calming a severe flare-up of dry eye symptoms.
What to expect: They provide rapid relief but are generally prescribed for short-term use only. Long-term use of steroids can increase the risk of side effects like high eye pressure (glaucoma) and cataracts. Your doctor will monitor you closely while you are using them.
2. Medications to Prevent Tear Evaporation
For many patients, the problem isn't a lack of tears, but that their tears evaporate too quickly. This is often due to a problem with the oily layer of the tear film, a condition known as Meibomian Gland Dysfunction (MGD).
Perfluorohexyloctane (Brand Name: Miebo®)
How it works: This unique medication is an eye drop that contains no water. It is designed to directly target tear evaporation. It forms a protective, thin layer over your tear film, acting like a shield to prevent your tears from drying out.
What to expect: It is often used by patients with MGD. The primary goal is to make the tears you have last longer, improving eye comfort and stability.
3. A Dual-Action Approach: Inflammation and Evaporation
A newer category of medication combines two approaches into a single drop, targeting both inflammation and tear evaporation.
Cyclosporine 0.1% (Brand Name: Vevye™)
How it works: Vevye uses the same trusted anti-inflammatory ingredient as Restasis and Cequa (cyclosporine) to help your body produce more of its own tears. The key difference is its delivery vehicle. It is formulated in a special, water-free solution that serves a dual purpose: it helps the cyclosporine penetrate the eye's surface more effectively and it also spreads across the tear film to help prevent evaporation, similar to the goal of Miebo.
What to expect: This combination may lead to faster symptom relief than other cyclosporine drops. It offers a two-pronged approach for patients who have both inflammatory and evaporative dry eye. The most common side effects are temporary stinging upon instillation and blurred vision.
4. Neurostimulators: Signaling for More Tears
This novel class of medication works by stimulating the nerves responsible for producing a complete tear film (water, oil, and mucin). Instead of supplementing tears, these drugs tell your body to make its own.
Varenicline Nasal Spray (Brand Name: Tyrvaya®)
How it works: This is a prescription nasal spray, not an eye drop. By stimulating a specific nerve inside your nose (the trigeminal nerve), it signals your eyes and glands to produce a complete, natural tear film.
What to expect: It works quickly, producing more tears within minutes of use. The most common side effect is sneezing right after application. It’s a great option for people who don’t like putting drops in their eyes.
Acoltremon Ophthalmic Solution 0.003% (Brand Name: TRYPTYR)
How it works: Working on the same principle as the nasal spray, TRYPTYR is an eye drop that acts as a neurostimulator. When applied to the eye, it directly activates nerve endings on the surface, sending a signal to your glands to increase natural tear production.
What to expect: This offers a different delivery method for neurostimulation. It also acts quickly to increase tear production. It is a good alternative for patients who prefer a traditional eye drop to a nasal spray. Common side effects may include temporary redness or stinging in the eye after use.

Partnering with Your Eye Doctor
Dry eye disease is complex, and there is no one-size-fits-all solution. The best treatment for you depends on the specific cause of your condition—whether it’s a lack of tear production, excessive evaporation, inflammation, or a combination of factors.
Your eye doctor can perform tests to diagnose the root cause of your dry eye and recommend the most appropriate medication. Be open about your symptoms, the treatments you've already tried, and any side effects you experience. Finding the right regimen can take time, but with the advanced options available today, significant relief is possible.
