Pink eye treatment depends entirely on what’s causing it. Viral pink eye, the most common type, clears up on its own in 7 to 14 days without medication. Bacterial pink eye improves faster with antibiotic drops but also resolves without them in more than half of cases. Allergic pink eye responds best to antihistamine eye drops you can buy over the counter. The first step is figuring out which type you’re dealing with.
Identifying Which Type You Have
The three main types of pink eye look and feel different enough to narrow down at home, though there’s overlap that can make it tricky.
Viral pink eye typically starts in one eye and spreads to the other within a day or two. The discharge is watery and clear, not thick. It often shows up alongside a cold, sore throat, or upper respiratory infection. This is the most common form and the most contagious.
Bacterial pink eye produces a thick, yellow or greenish discharge that crusts your eyelids shut overnight. Your eyelids may look swollen, and the eye can feel painful rather than just irritated. It can affect one or both eyes.
Allergic pink eye almost always affects both eyes at once and causes intense itching. If you also deal with hay fever, asthma, or eczema, allergies are the likely culprit. The discharge tends to be watery, and you’ll often notice other allergy symptoms like sneezing or a runny nose at the same time.
Treating Viral Pink Eye
There’s no medication that kills the viruses responsible for most pink eye infections. Like a common cold, you ride it out. Most mild cases clear up within 7 to 14 days, though some take 2 to 3 weeks.
What you can do in the meantime: apply cold compresses to the affected eye several times a day to reduce inflammation and soothe the irritation. Artificial tears (available without a prescription) help with the dryness and grittiness. Use a clean washcloth each time you wipe your eyes, and wash your hands constantly to avoid spreading the virus to your other eye or to other people.
Antibiotics won’t help viral pink eye. Taking them unnecessarily just increases the risk of side effects and antibiotic resistance.
Treating Bacterial Pink Eye
Antibiotic eye drops or ointments are the standard treatment, and your doctor will need to prescribe them. A typical regimen involves drops every two to four hours for the first two days, then four times daily for about five more days.
Here’s something worth knowing: a large review of clinical trials found that about 56% of bacterial pink eye cases resolved on their own within a week, even without antibiotics. With antibiotics, that number rose to 68%. So antibiotics do speed things up and improve your odds, but bacterial pink eye isn’t an emergency in most cases. The bigger benefit of antibiotics is reducing how long you’re contagious and lowering the small risk of complications.
If you wake up with eyelids glued shut by discharge, soak a clean washcloth in warm water and hold it over your closed eyes for a minute or two to soften the crust before gently wiping it away.
Treating Allergic Pink Eye
Allergic pink eye won’t go away until you reduce your exposure to the allergen or block your body’s reaction to it. The fastest relief comes from over-the-counter antihistamine eye drops. Look for drops containing ketotifen (sold as Zaditor or Alaway), which both block histamine and stabilize the cells that release it. One drop every 8 to 12 hours typically controls symptoms.
Another OTC option is olopatadine (Pataday), which works similarly and only requires one drop per day. These dual-action drops tend to work better than simple decongestant eye drops, which only reduce redness temporarily and can cause rebound redness if used for more than about 72 hours.
Cold compresses help here too, and oral antihistamines you may already take for seasonal allergies can reduce eye symptoms as part of your overall allergy management. If OTC drops aren’t enough, prescription options include stronger antihistamine drops or short courses of mild steroid drops for severe flare-ups.
What to Do About Contact Lenses
Stop wearing contacts immediately, regardless of which type of pink eye you have. Don’t put them back in until your symptoms are completely gone.
If you wear soft lenses, throw them away along with the case and any solution that was open during the infection. Soft lens solutions can kill the virus, but viral fragments may remain on the lens surface and trigger a recurrence. Disinfect the area where you store your lens supplies as well.
Rigid (hard) lenses can be saved by soaking them in hydrogen peroxide for at least 10 minutes, but the case and solution still need to be replaced. Start fresh with new supplies once your eyes have healed.
Stopping the Spread
Viral and bacterial pink eye are both highly contagious. They spread through direct contact with infected eye discharge or through touching contaminated surfaces, like a shared towel or pillowcase. You can be contagious for as long as your eyes are red and producing discharge.
Practical steps that actually matter:
- Wash your hands every time you touch your face or apply drops
- Use separate towels and pillowcases from the rest of your household, and change them daily
- Don’t share eye makeup, and throw away any eye cosmetics you used while infected
- Avoid touching your eyes, especially if only one eye is affected (this is how it spreads to the other)
Most schools and workplaces don’t require you to stay home with pink eye, but you’re actively contagious as long as symptoms are present. Kids tend to spread it easily in classrooms, so keeping them home for the first day or two, particularly while discharge is heavy, is reasonable.
Signs of Something More Serious
Most pink eye is uncomfortable but harmless. However, certain symptoms suggest something beyond routine conjunctivitis. Pay attention if you notice significant changes in your vision, like blurriness that doesn’t clear when you blink away discharge. Intense pain (not just irritation), sensitivity to light, or a feeling that something is stuck in your eye that won’t go away all warrant a prompt eye exam.
Pink eye that affects only one eye and appears alongside small blister-like sores near the eye or on the eyelid could be related to herpes simplex virus, which requires antiviral treatment to prevent damage to the cornea. And if symptoms haven’t started improving after a week of home care, or if they’re getting worse after the first few days, it’s time to get a professional evaluation rather than waiting it out.
