No, you should not use eye drops after their expiration date.
Why You Shouldn't Use Expired Eye Drops
Using expired eye drops, regardless of whether they are for pink eye (conjunctivitis) or another condition, is risky. Several sources confirm this:
- Loss of Sterility: Expired eye drops are no longer sterile and can introduce harmful bacteria or contaminants into your eyes, potentially leading to infection or irritation. [Source: River Height Eye Care]
- Reduced Effectiveness: The active ingredients in eye drops may degrade over time, rendering them ineffective at treating your condition. [Source: GoodRx, River Height Eye Care]
- Exacerbated Conditions: Using expired eye drops could worsen an existing eye condition like conjunctivitis instead of helping it. [Source: Calgary Optometry]
This applies to both opened and unopened bottles. Always check the expiration date on the bottle and discard any eye drops that have passed it.

Specific Considerations for Pink Eye
While some home remedies may temporarily alleviate pink eye symptoms (such as cool compresses), it's crucial to remember that pink eye can have various causes. Bacterial, viral, and allergic conjunctivitis require different treatments. Using expired eye drops for any type of pink eye is ill-advised and might hinder proper treatment. The CDC highlights the seriousness of pink eye in newborns, often necessitating antibiotic eye drops. [Source: CDC] Improper treatment can lead to severe eye damage. If you suspect you have pink eye, consult an ophthalmologist or your doctor for proper diagnosis and treatment.
