Bacterial pink eye usually clears up in 2 to 5 days without treatment, though it can linger for up to two weeks. Antibiotic eye drops or ointment speed recovery, reduce the chance of complications, and help you stop spreading the infection sooner. Most cases are mild and straightforward to treat at home once you have the right medication.
Whether You Need Antibiotics
Mild bacterial pink eye can resolve on its own without antibiotics. But there are good reasons to get a prescription anyway: antibiotics shorten the infection, lower the risk of complications, and cut down how long you’re contagious. Without treatment, you can spread the infection for as long as symptoms last. With antibiotics, that contagious window drops to roughly 48 hours after your first dose.
If your symptoms are limited to redness, some discharge, and mild irritation, you may be fine waiting a day or two to see if things improve. But if you have significant yellow or green discharge, if both eyes are affected, or if symptoms aren’t improving after a couple of days, getting antibiotics is the practical move.
What Antibiotic Treatment Looks Like
The most common prescription is antibiotic eye drops, typically applied to the affected eye every three hours, up to six times a day, for 7 to 10 days. Some providers prescribe an antibiotic ointment instead, which is applied less frequently but can blur your vision temporarily after each application. Ointments are often preferred for young children since drops are harder to administer.
The key rule: finish the entire course, even if your eye looks and feels normal after a few days. Stopping early can allow surviving bacteria to rebound, and you may end up right back where you started. Try to space your doses evenly throughout the day to keep a steady level of medication in the eye.
Cleaning Discharge and Crust
Bacterial pink eye produces more discharge than the viral type, often thick and yellow-green. It tends to build up overnight, sometimes crusting your eyelids shut by morning. To clean it safely, use a clean, damp cloth or moist cotton and wipe from the inner corner of your eye outward. Use a fresh section of the cloth for each wipe to avoid dragging bacteria back across the eye. Wash your hands before and after every time you touch your face or eyes.
A compress can help loosen stubborn crust and soothe irritation. Either cool or warm water works. A cool compress tends to feel more soothing for most people, but use whichever temperature is more comfortable. Hold the compress gently against the closed eyelid for a few minutes, then clean away any loosened crust. Use a separate cloth for each eye if both are infected.
Preventing Reinfection and Spread
Bacterial pink eye spreads easily through direct contact, shared items, and contaminated hands. While you’re infected, a few habits make a big difference:
- Wash your hands constantly. This is the single most effective step. Wash before and after applying eye drops, touching your face, or handling anything shared.
- Don’t share towels, pillowcases, or washcloths. Switch to a fresh pillowcase daily if possible.
- Avoid touching your eyes. If you need to wipe or itch, use a tissue and throw it away immediately.
- Stop wearing eye makeup. Don’t apply any cosmetics near your eyes until the infection has fully healed. Once it clears, throw away any eye makeup you used before or during the infection, especially mascara, eyeliner, and eyeshadow. Old contaminated products can reintroduce bacteria.
Contact Lens Rules During Infection
Stop wearing contact lenses the moment you suspect pink eye. Switch to glasses until the infection and any remaining irritation are completely gone. If you wear soft disposable lenses, throw away the pair you were using when symptoms started. Also discard your contact lens case, your current bottle of contact solution, and any eye drops that may have been contaminated. Start fresh with new supplies once you’re fully recovered. Before resuming lens wear, check with your provider to confirm the infection has cleared.
Going Back to Work or School
With antibiotic treatment, you’re generally no longer contagious about 48 hours after starting the medication. Many schools and workplaces follow this 24-to-48-hour rule, similar to policies for strep throat. Without antibiotics, you remain contagious for as long as symptoms persist, which could be up to two weeks. If avoiding close contact with others matters for your job or your child’s school, antibiotics significantly shorten that quarantine period.
Symptoms That Need Urgent Attention
Standard bacterial pink eye is uncomfortable but not dangerous. Certain symptoms, however, suggest something more serious is going on. Get prompt medical attention if you develop eye pain (not just irritation, but real pain), sensitivity to light, blurred vision that doesn’t clear when you blink away discharge, or intense redness that seems to be getting worse rather than better. These can signal a deeper infection, a corneal ulcer, or another condition that needs different treatment than standard pink eye drops.
