Treatment

Pink eye is a minor infection and can be easily treated at home:

1. Loosen and clean the eye discharge with a cotton ball soaked in warm water


2. Artificial tears (sold over the counter) can be used to relieve mild irritation


3. Antibiotic drops or ointment may be required if the following symptoms are present:
• Bright red discoloration of the eyes (eyes look red from across the room)


• Frequent accumulation of thick yellow or green discharge (must be cleaned every hour)


• Use the medicine for the length of time prescribed, even if the symptoms have resolved.
4. If the cause of the pink eye is allergies, your doctor may recommend an anti-histamine such as Benadryl


5. Symptoms usually resolve in three to seven days

Contagiousness

The viruses and bacteria that can cause pink eye are very contagious. Family members should not share wash clothes, towels, pillows, etc, with the affected family member. A child may return to school or day care once the discharge has improved.
