Symptoms
What are the symptoms of pink eye?
The pattern of redness, itching, discharge, and exposure history can help distinguish likely causes, but an eye assessment is important when symptoms are severe or the cause is unclear.
- Redness in the white of the eye or inner eyelid
- Watery discharge or thick yellow or green discharge that may crust the eyelids
- Itching, burning, grittiness, or a foreign-body sensation
- Swollen eyelids or increased tearing
- Symptoms in one or both eyes
Compare options
What treatment options may be considered?
The right option depends on the likely cause, severity, age, pregnancy status, allergies, medicines, and referral triggers. A pharmacist can help you choose a safe next step.
| Option | What it may help | Prescription required? | Important cautions |
|---|---|---|---|
| Lubricants and supportive care | Rinse allergens, soothe grittiness, and support comfort in viral or irritant-related cases. | Usually no. | Use sterile products, wash hands, avoid sharing towels, and stop contact lenses until assessed and resolved. |
| Allergy eye treatment | Relieve itching and watering when allergic conjunctivitis is likely. | OTC and prescription options exist. | Redness-relief drops are not suitable for everyone and prolonged use can worsen redness. |
| Antibacterial eye medication | Treat eligible bacterial conjunctivitis when antibiotics are clinically appropriate. | Some products require a prescription. | Antibiotics do not treat viral or allergic conjunctivitis. Contact-lens wearers and severe cases need careful assessment. |

- The pharmacist assesses the type of symptoms, discharge, affected eye, duration, exposures, contact-lens use, medications, allergies, and red flags.

Frequently asked questions
Pink eye treatment FAQs
Can a pharmacist prescribe pink eye treatment in Ontario?
Yes. Ontario’s minor-ailments framework includes bacterial, allergic, and viral conjunctivitis. The pharmacist assesses the likely cause and checks for eye pain, vision changes, contact-lens risks, injury, and other referral triggers before recommending or prescribing treatment.
Do all cases of pink eye need antibiotics?
No. Antibiotics treat bacterial infections, not viral or allergic conjunctivitis. Lubricants, allergy treatment, hygiene, and time may be more appropriate depending on the cause. An assessment helps avoid unnecessary or unsuitable antibiotic use.
What can I do at home for pink eye?
Wash your hands often, avoid touching your eyes or sharing towels, use clean warm or cool compresses as advised, and switch from contact lenses to glasses until symptoms resolve and a professional says it is safe to resume lens use.
When should I see a doctor for pink eye?
Seek prompt care for eye pain, vision changes, marked light sensitivity, injury, chemical exposure, severe swelling, symptoms in a newborn, or contact-lens-related symptoms. These can indicate a problem more serious than routine conjunctivitis.
