Pink Eye at Home: What Works, What Doesn't, and When You Need a Clinician

What are the three types of pink eye — and why does it matter?

Conjunctivitis (pink eye) is inflammation of the thin tissue lining the inner eyelid and the white part of the eye. The CDC recognizes three main causes, each handled differently 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk:

Viral conjunctivitis is the most common kind, caused by the same family of viruses responsible for the common cold (including adenoviruses and enteroviruses). It spreads easily, often affects both eyes — one may start first — and produces watery or slightly stringy discharge. Antibiotics do not help it.

Bacterial conjunctivitis causes thicker, pus-like yellow or green discharge that may crust the eyelids shut, especially in the morning. It is more common in children and often starts in one eye. Antibiotic drops or ointment may shorten the course.

Allergic conjunctivitis tends to affect both eyes simultaneously, causes intense itching, and often accompanies a runny nose and sneezing. It is not contagious and is treated with allergy medications, not antibiotics.

Knowing which type you likely have guides what will actually help — and what will not.

What can you safely do at home?

For all types, the CDC recommends 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk: - Apply a clean, damp compress — cool for allergy-related itch, warm for crusting from bacterial discharge — for several minutes a few times a day. - Gently wipe discharge from the inner corner of the eye outward using a clean cloth or cotton ball; use a fresh one for each wipe, and a separate one for each eye. - Wash hands frequently and thoroughly — at least 20 seconds with soap and water. - Do not share towels, pillowcases, or eye makeup. - Remove contact lenses until the infection fully clears.

Over-the-counter lubricating (artificial tear) eye drops can soothe irritation for any type. For allergic pink eye, OTC antihistamine eye drops can help significantly.

Do not use old prescription eye drops from a previous infection without a clinician's guidance — they may be the wrong type or may have expired and could cause harm 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk.

Do you actually need antibiotics?

For viral pink eye: no. Antibiotics treat bacteria, not viruses. Using them when they are not needed contributes to antibiotic resistance without speeding recovery 2Ref 2Chow AW, Benninger MS, Brook I, et al. (2012).IDSA Clinical Practice Guideline for Acute Bacterial Rhinosinusitis in Children and Adults.Antibiotic stewardship principle that antibiotics treat bacteria, not viruses, and should not be used when they provide no benefit — directly applicable to viral conjunctivitis and shared-decision-making context. Viral conjunctivitis typically resolves in 7 to 14 days on its own.

For bacterial pink eye: Antibiotic eye drops or ointment are often prescribed and can shorten the illness and prevent spread to others. However, many mild bacterial cases resolve without treatment within one to two weeks — a clinician can help decide whether the severity warrants a prescription 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk.

For newborns under 28 days old: Any eye discharge should be evaluated the same day. Neonatal conjunctivitis can have serious causes — including gonorrhea or chlamydia transmitted at birth — that require specific treatment and carry real risks if delayed 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk.

How long is pink eye contagious — and when can you return to school or work?

Viral and bacterial pink eye are both contagious, primarily through direct contact with eye discharge or by touching a contaminated surface and then touching your eye 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk. You are typically considered contagious as long as the eye is red and actively producing discharge.

Many schools and workplaces require staying home until 24 hours after starting antibiotic drops (for bacterial) or until symptoms substantially resolve. Allergic pink eye is not contagious.

Consistent handwashing during an active infection is the most important preventive step for household contacts.

When do symptoms warrant a clinician visit?

According to CDC guidance 1Ref 1Centers for Disease Control and Prevention (2024).Conjunctivitis (Pink Eye): Treatment and Prevention.Treatment by type (viral resolves in 7–14 days without antibiotics; bacterial may benefit from antibiotic drops; allergic requires allergy management); home care steps (compresses, hygiene, no shared items); when to see a clinician; neonatal conjunctivitis requiring same-day evaluation; contact-lens-related risk, see a clinician if you notice: - Eye pain — not just mild irritation or grittiness - Blurred vision or sensitivity to light that does not clear with blinking - No improvement after 7–10 days of home care - Contact lens wearers with any eye redness — the risk of corneal infection (keratitis) is significantly higher and may require specific evaluation - Symptoms in a newborn under 28 days old — same-day evaluation - Known exposure to a sexually transmitted infection — gonococcal conjunctivitis can cause rapid corneal damage and requires urgent treatment

People with weakened immune systems and anyone with recent eye surgery or eye trauma should also seek earlier evaluation rather than managing at home.
