Yes, Sudafed (pseudoephedrine) can potentially cause a false positive for amphetamines in drug tests. This is because pseudoephedrine is chemically similar to amphetamines, which can lead to cross-reactivity in certain immunoassay tests. However, confirmatory tests, such as gas chromatography-mass spectrometry (GC-MS), can differentiate between the two substances. If you are concerned about drug testing, it's advisable to inform the testing facility about any medications you are taking.
sudafed can give u a false positive for meth be careful
cocaine is an opiate... sudaphed can produce positive results for amphetamines(cocaine is NOT an opiate (it is derived from the coca plant not opium), but I do believe sudafed would only produce a false positive for amphetamines)
will buspirone cause a false positive for benzodiazipies
Even if sent to a lab, it shouldn't show up as meth at all. The tests are broken down and they will look for the poisons that are used in meth. I have talked to drug counselors regarding this very thing and was assured this fact. Good luck. I would stop using the Sudafed if you are worried about it.
False positive for methadone
At the risk of violating federal medical privacy laws, are you on antibiotics? Most of them--especially ones with "cillin" in their names--will cause a false positive for cocaine. Also, strangely enough, tonic water--which contains quinine--will cause a false positive for cocaine, and Sudafed has been known to.A GC/MS system will be able to determine whether the drug you're on is amoxicillin, Sudafed, gin & tonic, or cocaine.
Yes! Since Meth is made from it, if you take enough of it, you can eventually test positive for methampethamines. You can also test positive for meth if you take a lot of Sudafed and other cold medicines.
No, folliculitis will note cause a false positive HSV2 result.
not usually, especially if it's a test used specifically to detect DRUGS (i.e., urine analysis). however, sometimes it can cause a false positive for amphetamine in less sensitive tests.
can percocet cause a false positive for pcp
No.
Yes, Atripla can cause a false positive for a high reading of cannibinoids.
