What you can buy over the counter for pink eye depends on which type you have. Allergic conjunctivitis has the most OTC options, including antihistamine eye drops that directly treat the cause. Viral and bacterial pink eye have fewer store-bought solutions, but artificial tears and cold compresses can relieve symptoms while the infection runs its course. Antibiotic eye drops, which treat bacterial pink eye, require a prescription.
Figure Out Which Type You Have
Before grabbing something off the shelf, it helps to identify what you’re dealing with. The three main types of pink eye look and feel different, and the wrong product won’t help.
Viral pink eye causes redness, irritation, and a clear, watery discharge. It often starts in one eye and spreads to the other within a day or two. It frequently shows up alongside a cold or upper respiratory infection.
Bacterial pink eye produces a thick, yellow or greenish discharge that crusts around your eyes, especially overnight. You may wake up with your eyelids stuck together. The discharge is noticeably thicker than what you’d see with a viral infection.
Allergic pink eye almost always affects both eyes at once. The hallmark symptom is intense itching, along with redness, swelling, and excessive tearing. It tends to flare up around pollen, pet dander, or other known triggers.
OTC Options for Allergic Pink Eye
Allergic conjunctivitis is the type best served by over-the-counter products because antihistamine eye drops are available without a prescription and target the underlying problem.
Ketotifen 0.025% is one of the most widely available options. Sold under brand names like Zaditor and Alaway, it temporarily relieves itchy eyes triggered by pollen, grass, ragweed, and animal dander. It works both as an antihistamine (blocking the itch signal) and as a mast cell stabilizer (preventing your eyes from releasing the chemicals that cause inflammation in the first place). You typically apply one drop in each affected eye every 8 to 12 hours.
Olopatadine is another antihistamine eye drop now available OTC in several strengths under the Pataday brand, including 0.1%, 0.2%, and 0.7% solutions. The higher-concentration versions may only need once-daily dosing, which is more convenient. These products are generally safe for children aged 2 and older, though the age cutoff varies slightly by formulation.
OTC Options for Viral Pink Eye
Viral pink eye has no cure. Like a common cold, it has to run its course, which typically takes one to three weeks. No OTC drop will shorten the infection. What you can buy is comfort care.
Artificial tears (lubricant eye drops) are the primary recommendation. The CDC specifically advises using artificial tears and cold compresses to relieve the inflammation and dryness that come with pink eye. Look for preservative-free artificial tears if you plan to use them frequently throughout the day, since preservatives can irritate already-inflamed eyes with repeated use.
Cold compresses also help. A clean washcloth soaked in cool water and placed over your closed eyes for a few minutes can reduce swelling and soothe irritation. Use a fresh cloth each time and for each eye to avoid spreading the infection.
Why You Can’t Buy Antibiotic Drops OTC
If you suspect bacterial pink eye, you’ll need to see a doctor. Antibiotic eye drops are prescription-only medications in the United States. There is no OTC antibiotic eye drop currently available.
In the meantime, artificial tears and cold compresses can ease discomfort while you wait for an appointment. Mild bacterial pink eye sometimes resolves on its own within a week or so, but prescription drops can speed recovery and reduce the risk of spreading it to others. This is especially important if you wear contact lenses, since bacterial conjunctivitis in contact lens wearers carries a higher risk of a more serious corneal infection.
Be Careful With Redness-Relief Drops
It’s tempting to reach for drops marketed as “redness relievers” (products containing vasoconstrictors like tetrahydrozoline or naphazoline). These work by shrinking blood vessels on the surface of your eye, making the redness temporarily disappear. But they don’t treat any form of pink eye, and they come with a real drawback: overuse can cause rebound redness, where your eyes become even redder once the drops wear off.
Federal labeling rules require these products to carry a warning: if redness or irritation persists for more than 72 hours, stop using them and see a doctor. They’re designed for occasional cosmetic use, not for managing an active infection or allergic reaction. Stick with artificial tears for comfort and antihistamine drops if allergies are the cause.
Hygiene Steps That Actually Matter
What you do outside the pharmacy matters as much as what you buy in it. Pink eye, particularly the viral and bacterial types, spreads easily through contaminated hands and shared items.
If you wear contact lenses, stop wearing them immediately and don’t resume until your symptoms are completely gone. Throw away any disposable lenses and lens cases you used while your eyes were infected. Extended-wear or reusable lenses need to be thoroughly cleaned and disinfected before you wear them again.
Discard any eye makeup or face makeup you used during the infection. Mascara, eyeliner, and eyeshadow can all harbor the virus or bacteria. Don’t share these products, and don’t share towels, washcloths, or pillowcases with anyone in your household while symptoms are active. Wash your hands frequently, and avoid touching or rubbing your eyes, which can spread the infection from one eye to the other or to people around you.
Signs You Need More Than OTC Products
Most pink eye is mild and clears up without complications. But certain symptoms signal something more serious. Eye pain (not just irritation), sensitivity to light, blurred vision, or very intense redness that doesn’t improve after a few days all warrant a prompt visit to an eye doctor. These can indicate a more aggressive infection or inflammation affecting the cornea, which can lead to vision loss if untreated.
Pink eye that keeps coming back or won’t go away after several weeks also needs professional evaluation. Chronic conjunctivitis can sometimes point to an underlying condition that OTC products won’t address.
