Many people use eye drops in their daily lives, but a bottle of eye drops is relatively large. Generally, it is not used after a few days of continuous use and is thrown away in a corner. When I want to use it next time, I often struggle with this question: Can I still use the unused eye drops after opening them last time?

Let’s first understand what eye drops are?

eye drops are a sterile preparation, which can be divided into single-dose packaging and multi-dose packaging depending on whether preservatives are added or not.

Single-dose eye drops

Single-dose use packaging. Since it does not contain preservatives, it needs to be used immediately after opening. Discard after use and cannot be reused. The remaining unused liquid can be used within the storage conditions and validity period marked on the instructions. use.

Multi-dose eye drops

Multi-dose packaging, unless otherwise specified in the instructions, should be discarded and cannot be used after four weeks of opening. It is strongly recommended that for eye drops packaged in multiple doses, the opening time should be marked on the bottle after opening for the first time. And when using, avoid contact with eyes to avoid contaminating the liquid. If there are any changes in properties after opening, such as discoloration, turbidity, etc., you should discard it immediately or consult a doctor or pharmacist.
