Why Do Some Eye Drops Need to Be Refrigerated?

Eye drops are a crucial component in the management and treatment of various eye conditions, including glaucoma, dry eye, allergies, conjunctivitis, and others.

But improper storage conditions, and especially temperatures of your eye drops can significantly affect their efficacy and safety.

Eye drop storage temperatures

The need for refrigeration in some eye drops is primarily due to the ingredients they contain. Many formulations, especially those that are preservative-free, need a cool environment to maintain their stability and prevent bacterial growth. Refrigeration can extend the shelf life of these eye drops and ensure that their therapeutic properties remain effective until their expiration date. For drops containing sensitive compounds, cool temperatures prevent degradation, ensuring that each dose administered is both safe and effective. The recommended refrigeration temperature for these refrigerated eye drops is typically between 2°C and 8°C (35°F to 46°F).

Additionally, depending on your specific eye condition and doctor's recommendations, applying cold eye drops can have additional benefits, such as reducing itching and swelling in conditions like allergic conjunctivitis. The cool temperature can also help soothe eyes after exposure to irritants or during episodes of dry eye by providing a refreshing sensation that may temporarily relieve discomfort.

In any case, whether they need to be refrigerated or not before use, all eye drops must be stored at controlled temperatures. For eye drops that do not require refrigeration, they typically must be stored between 15°C and 25°C (59°F to 77°F). Keeping them within this range helps maintain their efficacy and safety. It is crucial to avoid exposing your eye drops to extreme temperatures, both hot and cold, as well as direct sunlight, which can alter their chemical structure and effectiveness.

How Long Are Eye Drops Good For?

The shelf life of eye drops, both before and after opening, varies significantly based on their formulation, packaging, and preservatives used.

Before opening

Unopened eye drops generally have a shelf life of 1 to 3 years, depending on the specific ingredients and preservatives used. This expiry date assumes that the drops are stored correctly, typically at room temperature and away from direct light, unless otherwise specified (like those needing refrigeration). It's important to always check the expiration date printed on the bottle or box before use.

After opening

Once opened, the shelf life of eye drops can vary significantly. Preservative-free eye drops are often packaged in single-use vials and should be used immediately upon opening. If they are in multi-use bottles, they typically need to be used within 14 to 30 days after opening, as they lack preservatives that would help prevent bacterial growth.

Eye drops with preservatives can generally be used for up to 28 days after opening, though some may last longer up to 90 days. The preservatives help prevent microbial growth, which can contaminate the drops and pose a risk to eye health.

General Tips for Eye Drop Storage

  • Check expiration dates. Always observe the expiry dates provided on the packaging. Do not use eye drops beyond these dates.
  • Mark the opening date. It's a good practice to write the date of opening on the bottle to help keep track of how long the drops have been in use.
  • Follow storage instructions. Adhere strictly to storage instructions. Some drops require refrigeration, while others should be kept at room temperature.
  • Observe changes in the solution. If you notice any discoloration, cloudiness, or particulate matter in the eye drops, discard them immediately and ask for your doctor or pharmacist's advice.
  • Maintain good hygiene. Avoid touching the dropper tip to any surface, including the eye, to prevent contamination.

By following these guidelines, you can help ensure that your eye drops remain effective and safe for use, minimizing risks of eye infections or complications from improper medication usage.
