How long can Japanese eye drops be used after opening

The shelf life of eye drops is generally one to two years, but don’t assume that opened eye drops can be used until the expiration date. Experts point out that once eye drops are opened and come into contact with the air, they should be discarded after two months even if they are not completely used up. Eye drops are medicine after all, so when the eyes are sick, antibiotics, hormones, steroids and other ingredients must be added to inhibit bacterial growth.

How long is the shelf life of Japanese eye drops

Food has a "shelf life", while medicine should have an "expiration date". The expiration date of eye drops refers to the expiration date of the eye drops when they are unopened (i.e. the bottle cap is not opened). It is valid at any time during the validity period. If it has passed the validity period, it will be invalid regardless of whether it is opened or not. After eye drops (ointments) are opened, they should generally be discarded after three months, especially eye drops that do not contain preservatives or special ingredients, which should generally be used up within one month.
