I'm just a technician working in a hospital pharmacy but even I know there is something wrong with disposing of IV antibiotics down the drain. Most of the pharmacist I work with are "old school" so they really don't care. I know there has got to be some sort of protocol. Heck, we can't even throw away basic organic chemicals in O-Chem, so how is it safe to dump antibiotics like: Levaquin/Vancomycin/Zyvox/Rocephin/Caspofungin/Fortaz/Ancef/premixed amino acids and lipids down the drain? Also, if it is a bad thing to do, how would you dispose of them properly?
