Yes you need a full 72 hours for it to clear your system
Urine test will show both and without a prescription for both you will fail test
No Darvocet will show up as narcotics on a drug test same as Percocet or vicodin.
3-5 days
Yes, they are both opiates.
Yes
It will show up on a 10 panel as a opiate base both of them
No, but the odds that anyone tests for Darvocet is really low. yes you would test positive for propoxaphene The active ingredients in Darvocet are propoxyphene and actetamenophen a standard urine drug screen does test for that substance sorry you got your hopes up with the previous false answer
I believe the question word you are looking for is "do" not "is" and the answer to both is "you is an idiot"
It depends on the methodology. My laboratory screens for a panel of 10 drugs, including opiates. Since darvocet is a synthetic opioid, it will not show up. It may be detected by other drug screen panels. Some newer drug panels do include tests for propoxyphene, which is one of the active ingredients in darvocet.
