Reply To: Stability of drugs drawn up prior to use
Essentially it’s not a problem drawing up benzodiazepines and leaving them in syringes until you use them.
Historically, syringes in the 1970s and 80s contained a lot more rubber than the ones we use now which could react with diazepam if allowed to sit together for some time. Unfortunately, it’s been accepted into the received wisdom people cite without an update for modern materials. Therefore I wouldn’t worry about it if it’s just for a few hours.
Hope that helps.
