What you get for pink eye depends entirely on the type you have. Most cases are viral, which means no prescription medication will speed them up. Bacterial pink eye is treated with antibiotic eye drops or ointment, and allergic pink eye responds to antihistamine drops. Here’s what to expect for each type and what you can do on your own in the meantime.
Viral Pink Eye: No Prescription Needed
Most pink eye in adults is viral, and there’s no antibiotic or antiviral drop that treats the common forms. It clears on its own, usually within one to two weeks. That doesn’t mean you have to just suffer through it, though. The standard approach is comfort care at home:
- Artificial tears for lubrication, used four times a day or up to ten times daily if you choose preservative-free drops
- Cool compresses with a wet washcloth held against the eye area for symptom relief
- No contact lenses until symptoms fully resolve
That’s essentially the full playbook. A doctor visit often confirms it’s viral and sends you home with these same instructions. The focus shifts to keeping yourself comfortable and not spreading it to your other eye or to other people. Wash your hands frequently, don’t share towels, and avoid touching your eyes.
Bacterial Pink Eye: Antibiotic Drops or Ointment
If your doctor determines the infection is bacterial (thick yellow or green discharge is a common clue), you’ll likely get a prescription for antibiotic eye drops or an ointment. Almost all cases of bacterial pink eye are self-limiting and will clear within about 10 days even without treatment, but antibiotics can shorten the course and reduce symptoms faster, particularly in the first two to five days.
The most commonly prescribed options fall into a few categories. Fluoroquinolone drops like moxifloxacin or ofloxacin are widely used. Erythromycin ointment is a go-to choice, especially for children, applied as a small ribbon of ointment directly into the eye up to six times a day depending on severity. Combination drops containing polymyxin B and trimethoprim are another common choice. Your doctor picks based on the likely bacteria involved, your age, and whether you wear contacts.
Contact lens wearers with bacterial pink eye need extra attention. Wearing lenses during an infection raises the risk of a more serious corneal infection. Remove your lenses right away, throw away the pair you were wearing, and replace your lens case, solution, and any eye drops that may be contaminated. Don’t put contacts back in until the infection and all irritation are completely gone.
Allergic Pink Eye: Antihistamine Drops
If your pink eye is triggered by pollen, pet dander, or dust rather than an infection, the treatment looks different. Itching is the hallmark symptom here, and the fix is antihistamine eye drops that block the allergic reaction right at the surface of the eye.
Several are available over the counter. Ketotifen drops are one of the most accessible options and work as both an antihistamine and a mast cell stabilizer, meaning they block the itch and help prevent it from coming back. Prescription-strength options include olopatadine and alcaftadine, which work similarly but at higher potency. These drops are typically used once or twice daily and provide relief within minutes.
Cold compresses and preservative-free artificial tears help here too, flushing allergens off the eye surface and soothing inflammation. If your allergies are seasonal and predictable, starting antihistamine drops before peak season can prevent symptoms from developing in the first place.
What About Redness-Relief Drops?
If your instinct is to grab a bottle of redness-relief drops from the pharmacy, hold off. These drops work by constricting blood vessels in the eye to temporarily reduce redness, but they don’t treat the underlying cause. Ophthalmologists generally discourage their use for pink eye. They can mask symptoms, cause rebound redness when you stop using them, and delay proper treatment. Artificial tears are a better over-the-counter choice regardless of which type of pink eye you have.
Herpes-Related Pink Eye: Antiviral Treatment
In rare cases, pink eye is caused by the herpes simplex virus. This is a more serious situation and requires antiviral medication rather than the “wait it out” approach used for typical viral conjunctivitis. Treatment usually involves an antiviral ointment or gel applied to the eye five times a day for about two weeks, sometimes paired with an oral antiviral pill. People with recurring herpes eye infections may take a low-dose oral antiviral daily for six months to a year to prevent flare-ups. If your doctor suspects herpes involvement, you’ll typically be referred to an ophthalmologist promptly.
How Long Until You Feel Better
Timelines vary by type. Bacterial pink eye with antibiotic treatment often improves noticeably within two to three days, though you should finish the full course of drops as prescribed. Without antibiotics, expect up to 10 days. Viral pink eye is the slowest to resolve, commonly lasting one to two weeks with a peak in symptoms around days three through five. Allergic pink eye improves the fastest once you start antihistamine drops, often within the same day, but it can return whenever you’re re-exposed to the allergen.
Regardless of the type, if your vision changes, you develop significant pain (not just irritation), or symptoms worsen after several days of treatment, that warrants a follow-up visit. These can signal a more serious condition like a corneal infection that needs different management.
