No.
They are opiates so , yes.
Ephedrine can show a false positive for amphetamines on a drug test.
No, Zyrtec does not contain any ephedrine/psyeudoephedrine ingredients.
No.
No. Absolutly not.It will come up positive for "Opiates"
if its in your system theirs no false positive. Actually several drugs can cause false positives in different categories on a standard drug test...such as any ephedrine containing product can show up as a positive for meth, so if you have been using weight loss/energy pills containing ephedrine or perhaps an asthma drug containing ephedrine you may show positive for meth on your drug test. Basically, just be up front and tell the tester all of the OTC and prescription drugs you are taking and they will do further testing if necessary to rule out any street drug/illicit use.
it can make you test positive for opiates.
Yes
opiates
I think it will only show positive for opiates on a drug screen.
will you test positive for oxycontin and opiates if you are taking both
Suboxone is an opiate. You will fail for opiates, not methamphetamines.
