Best over-the-counter options for pink eye (conjunctivitis)
Over-the-counter only — nothing here needs a prescription. Want the prescription options too? Every pink eye (conjunctivitis) option we rate, prescription included →
Most pink eye is viral or allergic, not bacterial — and neither responds to antibiotics. The American Academy of Ophthalmology calls viral conjunctivitis "the most common" type, and the CDC notes viral pink eye "usually clears up in 7 to 14 days" (sometimes 2 to 3 weeks), and bacterial "usually clears up in 2 to 5 days ... but can take 2 weeks." There is no OTC antibiotic eye drop in the United States — antibiotic drops are prescription-only, and the CDC states plainly that "Antibiotics will NOT improve viral pink eye; these drugs are not effective against viruses" (and antibiotics do not help allergic pink eye either). So "OTC pink eye medicine" is really supportive care: artificial tears and a cool compress to ease viral irritation, and OTC antihistamine/mast-cell drops for the allergic kind. What actually matters is knowing the danger signs — vision changes, real pain, light sensitivity, a contact-lens wearer, or a newborn — that mean you skip the drugstore and see a clinician.
Your OTC options, honestly rated
Artificial tears / lubricating eye drops
Relieves symptomsPreservative-free or standard lubricating drops rinse and soothe the eye surface, diluting irritants and easing the gritty, burning feeling of viral or irritant conjunctivitis. They do not kill any germ — they only make the eye more comfortable while your body clears the infection.
CDC: "Use cold compresses and artificial tears to help relieve some of the inflammation and dryness caused by pink eye. You can purchase these over the counter without a prescription." AAO and CDC agree viral conjunctivitis has no specific cure and resolves on its own.
Caution: Comfort only — not a cure and not a substitute for a clinician if red-flag signs appear. Use single-use vials or don't touch the dropper to the eye to avoid re-contaminating; discard eye makeup and don't share drops. Avoid contact lenses until symptoms fully clear.
Cold compress
Relieves symptomsA clean, cool, damp cloth held over closed eyes reduces the swelling, heat and itch of viral and allergic conjunctivitis. It is the simplest, cheapest form of relief and is explicitly endorsed by major eye-health authorities.
CDC: "Use cold compresses and artificial tears" to relieve inflammation and dryness. NHS advises "a cold flannel to the eyes for several minutes" for relief. NHS advises "a cold flannel to the eyes for several minutes" for relief.
Caution: Use a fresh, clean cloth each time and never share it — viral and bacterial conjunctivitis spread easily by contact. Symptom relief only; does not shorten or cure the infection.
OTC antihistamine / mast-cell-stabilizer drops (ketotifen — e.g. Zaditor, Alaway)
Effective first-line OTCKetotifen is an OTC dual-action antihistamine and mast-cell stabilizer that blocks the allergic response driving itchy, watery, red eyes. It targets the ALLERGIC form of conjunctivitis specifically — the mechanism that makes eyes itch on exposure to pollen, dander or dust.
CDC on allergic pink eye: patients may use "allergy eye drops to help with the itchiness and puffiness," and the AAO notes "Allergic conjunctivitis is not contagious." MedlinePlus and NHS both list antihistamine drops as appropriate for the allergic type. Ketotifen is FDA-approved for OTC sale for itching due to allergy.
Caution: Works only for ALLERGIC conjunctivitis — useless against viral or bacterial infection. If itch is not the dominant symptom, or there's significant discharge, pain or vision change, this is the wrong tool. Not for children under about 3 without a clinician; NHS notes under-2s need a prescriber.

Relieves symptomsA warm, damp cloth softens and loosens the crusting and sticky discharge common in bacterial and some viral conjunctivitis, and gentle lid cleaning removes debris so eyes open more comfortably in the morning.
NHS self-care: wash eyelids with "boiled, cooled water" and gently wipe lashes with clean cotton wool to remove crusts. Hygiene is supportive comfort/cleanliness, not an antimicrobial treatment.
Caution: Cleaning away crust does not cure a bacterial infection — it manages symptoms. Use a clean cloth/cotton once and discard; wash hands before and after. If sticky discharge is heavy and persistent, or a newborn has a sticky red eye, see a clinician.
"Redness-relief" vasoconstrictor drops (naphazoline, tetrahydrozoline — e.g. Visine)
Limited evidenceThese OTC drops constrict the eye's surface blood vessels to make redness fade cosmetically. They do nothing to the virus, bacteria or allergy causing conjunctivitis — they only mask the red appearance for a few hours.
Cosmetic "redness relief" vasoconstrictor drops are not a treatment for the underlying infection, and regular use causes rebound redness (conjunctivitis medicamentosa): vessels dilate worse as the drop wears off, driving a dependence cycle.
Caution: Not a treatment. Masking redness can hide a worsening infection and delay needed care, and rebound redness makes eyes look worse over time. Skip these for pink eye — reach for artificial tears (for comfort) or antihistamine drops (for allergy) instead.

See a clinician if…
- Changes in vision — blurring, wavy lines, or flashing lights (AAO/NHS list vision change as a reason to be seen right away)
- Eye pain, light sensitivity, or blurred vision that does not clear when discharge is wiped away (on the CDC’s "see a healthcare provider" list)
- Increased sensitivity to light (photophobia) — CDC and NHS both flag this
- Intense redness of the eye (CDC danger sign)
- You wear contact lenses — stop wearing them and be evaluated; CDC warns contact-lens wearers risk bacterial keratitis
- A newborn (under ~4 weeks) with a red, sticky or discharging eye — CDC: newborns "should see a doctor right away" as it can cause serious harm
- Symptoms that get worse instead of improving, or don't improve after 1–2 weeks (CDC/AAO)
- A weakened immune system — e.g. from HIV or cancer treatment (CDC warrants medical care), or symptoms after an eye injury
Bottom line
Most pink eye is viral or allergic and clears on its own — the honest "OTC treatment" is supportive: artificial tears and a cool compress for viral irritation, and OTC ketotifen antihistamine drops (Zaditor, Alaway) if it's the itchy, allergic kind. There is NO over-the-counter antibiotic eye drop in the US — antibiotic drops are prescription-only and useless against viral or allergic pink eye anyway. Skip cosmetic redness-relief drops (naphazoline/tetrahydrozoline): they don't treat anything and cause rebound redness. See an eye doctor for vision changes, real pain, light sensitivity, intense redness, a newborn, or if you wear contact lenses.
