Darvocet was removed from the US market some years ago, but if you've been using some from an unconventional source, you may be in danger of failing a drug test. Of course, your body will clean itself, but how long does it take for Darvocet to leave your system? When can you safely pass a drug test?
Firstly, Darvocet is the brand name for a product containing a combination of acetaminophen and propoxyphene, which is a narcotic painkiller. Obviously the acetaminophen should not cause any problems, but the propoxyphene may show up.
If you're still using Darvocet or another form of propoxyphene, you should probably look into alternatives. This drug was removed from the market in 2010 amid suspicion that it put patients health at risk from potentially fatal heart rhythm abnormalities. The drug can also have severe withdrawal symptoms, so it's likely that your doctor will switch you to an alternative opioid like tramadol or hydrocodone rather than recommend an abrupt stop.
Fortunately, however, the side effects of Darvocet don't appear to be cumulative, so even if you've been using it for a while, you shouldn't be at risk once you stop using it.
Which drug tests can detect Darvocet?
Prescription opioid painkillers (other than morphine and codeine) are not usually detected on the opiates panel of a 5-panel drug test. They can, however, be detected using the extended drug tests that are becoming increasingly popular. These extended tests are not limited to the usual street drugs, and they cover a range of commonly abused prescription drugs and popular "club" drugs.
If you're unsure of whether you'll be taking a standard or extended drug test, it's best to play it safe and prepare for the worst.
How long does it take Darvocet to leave your system?
Opioid painkillers often leave the body after about four days, but we found a supplier of urine testing devices that claims a ten-day detection period for propoxyphene. If this is true, and we see no reason to doubt it, it makes it very hard to prepare for a drug test just by abstaining. If you have the time, you may want to consider a 7-day detox program.
The hair, meanwhile, can hold traces of drugs like Darvocet indefinitely, although drug tests usually only use the last 90 days of growth. This means you will probably need to use a detox shampoo before a hair drug test.
Passing a drug test for Darvocet
Fortunately there are other ways to pass a drug test, even if you took Darvocet recently. If you need to take a urine drug test, you can prepare by using a detox drink about two hours before your test. This will dramatically lower the concentration of toxins, including propoxyphene, in your urine.
It's hard to predict the detection time for propoxyphene in a saliva drug test due to a lack of data and variability among devices, but you can easily prepare yourself with a detox mouthwash. You use this much like a normal mouthwash, although you may need to spend a little longer than with your normal routine.
