Answer 2

Drugs have an expiration date on the bottle. You have to look at that date to see how long the medicine is stable - if it is a smaller bottle from a pharmacy, you shouldn't keep it for more than a year from the date it was dispensed because you don't know what the original expiration date of the nystatin might have been.

Answer 3

You will have to look on the bottle to find how long is left. There should be an expiration or best by date there.
