Maybe; no: False positive for which drug? Check out http://www.askdocweb.com/falsepositives.html. Claritin (loratadine) may give false positive for amphetabmines. Depending upon decongestant (pseudoephedrine), you might also test positive for amphetamines or meth. Flonase (fluticasone) wasn't on list.
