Please ignore my previous post regarding the HUGE difference in volumes, I hadn't read this post before replying.
the Demerol dose was 75mg which is a normal dose for an adult. They do mix it with water in the vial but I don't know the injection cc amount for a 75mg dose. Do you?
Demerol 75mg. is only manufactured in 1 cc volume. However, 75mg. can be obtained from a multi-dose vial. Example: 50mg/cc, total volume = 1.5 cc.
