Not much if the drug was stored properly. The article mentions, prescription drug expiration dates are usually just shortened from manufacturer expiration dates. Probably just used by the pharmacy as a 'sell-by' date. Most perscription drugs are quite stable and there is nothing I am finding to indicate Ambien is any kind of exception.
My sister is a pharmacy technician, I'll ask her about expiration dates tomorrow to try and confirm this.
Nullific Reviewed by Nullific on . Question about prescription pills I found some old pills that i wanna take but its past the "use by" date. Does that mean if I take em they wont work or could something possibly bad happen if i took them? Rating: 5
