Is augmentin dangerous if the date of expiration has gone by or is it just less affective?

I work in a hospital pharmacy. When a medication is taken from it's original bottle, we refer to this process as prepacking. It is standard practice that when a medication is prepacked, it is given a one year expiration date regardless of the date on the original bottle (unless the original bottle expires in less than a year). That being said, the chances that the augmentin is actually expired is slim. Augmentin and Amoxicillin are widely used medications and generally are not on the shelf for very long suggesting that new bottles are stocked regularly with newer expiration dates. That being said, there is also a chance that the date on the medication bottle is the same as the original bottle.

I have a bottle here at the house it was stopped because of change to IV meds the bottle says after so many days discard, medications are not suppose to be used after the expiration date, I don't mean to sound rude but everytime you take an antibiotic the entire course is to be finished unless otherwise stated by a doctor. also this time you might have a different type of bacteria and you might need a diffeent antibiotic. if you have any further questions please feel free to ask or contact your doc or pharmacist

Meds after the expiry date are not recommended to be used, they become less effective, however please also double check it with a pharmacy.

Take care, be well, please!
