The multi dose unit systems generally have preservative in them which help eye drops to maintain their shelf life.

But still its recommended to use within 28 days of opening the eye drops because after that time it becomes unfit for use.

Eye drops are the one the most unstable products that has very short shelf life and are quickly regarded.

Eye drops are available in single unit and multi dose unit systems.

One is a general rule for how long the eye drop inside can stay relatively free of microbes.

Once the shelf life gets over the microbes start growing inside, now it increases risk of using this eye drops which potentially provides infection to the eyes.

Therefore unit dose has to be used at once and multi dose unit with three months of its opening.

No, in my opinion one shouldn’t use eye drops after its expiration date because it not only my opinion but suggested by the regulatory authorities FDA and other agencies.

Some of unit dose eye drops which are preservative free or have preservation should be used all at a time because this are highly sterile and once its opened chances of contamination are at peak.
