What is the shelf life of eye drops or artificial tears?
2025.07.13 21:40
Should I throw away eye drops or artificial tears that I put in my eyes after their expiration date?
My eyes were sore and itchy, so I took some medicine and it got much better.
Artificial tears also have a long shelf life, so it's a bit difficult to use them.
Does the efficacy of unopened medicine decrease after the expiration date?
Or is it okay to open it and use it?
