I am a new employee in an ASC - Mohs Surgery (skin cancer). We draw up the lido w/epi, bicarb & clindamycin into 3ml syringes and date them for expiration 2 weeks from being drawn up. Then, they also date it for another week out if the 2 week date comes and the syringe has not been used. At another derm office I worked in, they were only "good" for 1 week.
When I asked why they aren't just dated with a 3 week expiration, I got the standard "That's the way it's always been done". AUGHHH!!!
Does any one know how long a medication can be in a syringe?
