What are Eye Drops?
Eye drops are a common form of medication used to treat various eye problems such as allergies, dryness, infections, and glaucoma. They are a simple and effective way to deliver medication directly to the eyes, where it is absorbed quickly.
What Happens When Eye Drops Expire?
Like any medication, eye drops have an expiry date. This date signifies the point at which the medication is no longer guaranteed to be safe and effective to use. When eye drops expire, the chemicals in the medication can start to break down, or the preservatives used to prevent bacteria growth may no longer be effective. This can lead to a decrease in the effectiveness of the medication or even the growth of harmful bacteria.
Is it Safe to Use Expired Eye Drops?
While it is possible to use expired eye drops, it is not recommended. Eye drops that are past their expiry date may not be as effective as they once were, and some may even be harmful to your eyes.

- The eye drops may not work as expected and could lead to further eye damage
How Can You Tell if Eye Drops are Expired?
Every bottle of eye drops has an expiry date printed on the label. This date can typically be found on the side or bottom of the bottle. If you are unsure if your eye drops are still safe to use, it is best to check the expiry date before using them.
You should also keep in mind that once a bottle of eye drops has been opened, the expiry date no longer applies. Instead, the drops should be used within a certain time frame, typically between 30 and 90 days, depending on the medication.
How to Store Eye Drops to Prevent Expiration
To ensure that your eye drops last as long as possible, it is essential to store them correctly. It is recommended to store eye drops in a cool, dry place, away from direct sunlight. You should also avoid touching the dropper tip to any surface or letting it come into contact with your eyes to prevent contamination.
How to Dispose of Expired Eye Drops Safely?
If you have eye drops that have expired, the safest way to dispose of them is to bring them to a pharmacy that accepts medication for safe disposal. Do not pour them down the sink or toilet as this can lead to contamination of the water supply.
