It depends on the type of pink eye you have. Antibiotic eye drops, which treat bacterial pink eye, require a prescription in the United States. But several over-the-counter products can relieve symptoms or, in the case of allergic pink eye, treat the underlying cause directly.
Why Antibiotics Aren’t Available Over the Counter
If your pink eye is caused by bacteria, the standard treatment is antibiotic eye drops or ointment prescribed by a doctor. You cannot buy antibiotic eye drops over the counter in the U.S. This means that for true bacterial pink eye, with its hallmark thick yellow or green discharge and crusted-shut eyelids in the morning, you’ll need to visit a healthcare provider to get the right medication.
Bacterial pink eye can sometimes clear on its own within a week or two, but antibiotics speed recovery and reduce the window during which you can spread the infection to others.
What You Can Buy Without a Prescription
Two categories of OTC eye products are genuinely useful for pink eye: artificial tears and antihistamine drops. Which one matters depends on the cause.
Artificial Tears
Preservative-free artificial tears (lubricating eye drops) are the go-to OTC option for viral pink eye, which is the most common type. There’s no medication that kills the virus. Like a common cold, viral pink eye runs its course over one to three weeks, and treatment is purely about comfort. Artificial tears soothe the gritty, burning sensation and help wash away discharge. Cold compresses applied to closed eyelids also reduce inflammation and provide relief.
The CDC specifically recommends cold compresses and artificial tears as over-the-counter measures for relieving pink eye symptoms. Preservative-free formulas are the better choice because preservatives can irritate already-inflamed eyes.
Antihistamine Eye Drops
If your pink eye is caused by allergies, you’re in luck. OTC antihistamine eye drops like ketotifen and olopatadine treat allergic conjunctivitis directly by blocking the histamine response that causes itching, redness, and watering. These are true treatments, not just symptom relief. Ketotifen has been available over the counter for years, and olopatadine (once prescription-only) is now sold without a prescription as well. You’ll typically notice improvement within minutes of the first drop.
Allergic pink eye is usually easy to identify: both eyes are affected, itching is the dominant symptom, and you likely have other allergy symptoms like sneezing or a runny nose. It’s not contagious.
Skip the Redness-Relief Drops
It’s tempting to grab a bottle of redness-relief drops to make your eyes look better fast. These contain decongestants that constrict blood vessels, temporarily reducing redness. The problem is what happens after they wear off. Your eyes can become even redder than before, a cycle called rebound redness that worsens with repeated use and can lead to persistently bloodshot eyes.
The American Academy of Ophthalmology recommends using preservative-free artificial tears instead. If lubricating drops alone clear the redness, you avoid the rebound effect entirely.
How to Apply Drops Without Spreading Infection
Pink eye is highly contagious (bacterial and viral types), and sloppy drop application can spread the infection to your other eye or contaminate the bottle. A few steps make a real difference:
- Wash your hands with soap and water before touching anything near your eyes.
- Tilt your head back, pull your lower eyelid down to create a small pocket, and squeeze the drop into that pocket rather than directly onto your eyeball.
- Keep the bottle tip away from your eye, eyelid, and fingers. If the tip touches your infected eye, the entire bottle is contaminated.
- Press gently on the inner corner of your eye (near your nose) for about a minute after the drop goes in. This keeps the medication in your eye instead of draining into your tear duct.
If only one eye is infected, use a separate bottle or be extremely careful not to let the tip contact the infected eye before using it on the healthy one.
How to Tell Which Type You Have
Choosing the right OTC product requires knowing what kind of pink eye you’re dealing with. Here’s a quick breakdown:
- Viral: Watery discharge, often starts in one eye and spreads to the other, frequently accompanies a cold or upper respiratory infection. Treat with artificial tears and cold compresses.
- Bacterial: Thick yellow or green discharge, heavy crusting on lashes after sleep, can affect one or both eyes. Needs prescription antibiotics.
- Allergic: Intense itching in both eyes, watery or stringy discharge, occurs alongside seasonal allergy symptoms. Treat with OTC antihistamine drops.
Signs That Need Medical Attention
Most pink eye is uncomfortable but harmless. However, certain symptoms signal something more serious. The CDC advises seeing a healthcare provider if you experience eye pain, sensitivity to light, blurred vision, or intense redness. These can indicate a deeper eye infection, corneal involvement, or a condition that isn’t actually conjunctivitis at all. Newborns with any eye redness or discharge need immediate medical care.
