Does amoxicillin own a shelf existence?
All medications own a shelf life. See if at hand is an expiration date or ask you pharmacist. Also, antibiotics are to be taken until gone. THey give you ample to use for the course of treatment needed. There should never be any extra.
they do have a shelf go,,,but i have also be told that they might lose some of the potency after the expiration date
