Does Sudafed make you test positive for amphetamines?

Answer 1

yes it can produce false positive results. this occurs with tests that use antibodies that screen for amphetamines. sudafed contains pseudoephedrine that is similar in structure to amphetamines and therefore causes cross-reactivity with the antibodies directed against amphetamines.

if a test is being done in a legal manner; e.g. a workplace drug screen, the initial immunoassay needs to be followed up with a more precise assay - usually GC-MS. This assay will be able to differentiate between sudafed and amphetamines

Answer 2

It is possible for sudafed, robitussin and other over the counter meds cause a false positive in some drug tests. if this has happened to you and the test wasn't sent to a lab you could ask it be sent and ask the lab to determine a over the counter caused the positive result or you could ask for a 2nd test if you have discontinued use of sudafed

Answer 3

Sudafed contains the same chemical properties as amphetamines, and will be screened as an amphetamine on certain drug test(non-specific drug tests), but Sudafed is not an amphetamine.

Answer 4

There is potential that it could if a person were submitted to a urine test.
