... is this true?
If it has phenylephrine in it it can cause a false pos amphetamine.
It shouldnt show up since it is over the counter but sometimes drugs trigger false positives in immunoassay tests. These can be confirmed as false positives with a more accurate test called GC-MS. Dont worry overly, it really shouldnt show but if you do get a false positive, be sure that they retest it using GC-MS to confirm.
