# When to discard old eye drops?

Eye drops do not last forever, and using them after they expire can increase infection risk or reduce effectiveness.

## General rules for discarding drops

Most bottles have both an expiry date and a recommended period after opening. Once opened, the contents gradually lose sterility, even with preservatives.

- Check the label for "discard X days after opening" guidance
- Many preserved bottles should be thrown away after 28 days
- Single-use vials are for one day only, even if some liquid remains
- Never use drops past the printed expiry date on the box or bottle

## Safe storage and handling

Proper handling keeps drops effective for as long as intended. This is especially important for medicated drops used after surgery or for glaucoma.

- Store as directed, often at room temperature and away from direct sunlight
- Avoid touching the tip to the eye, lashes, or fingers
- Write the opening date on the bottle as a reminder
- Dispose of unused prescriptions safely, following pharmacy advice
