    check the list of active ingredients for the antihistimines you use. The following ingredients and meds can cause false positives for amphetamines (from erowid):
    Ephedrine, pseudoephedrine, propylephedrine, phenylephrine, or desoxyephedrine
    (Nyquil, Contact, Sudafed, Allerest, Tavist-D, Dimetapp, etc)
    Phenegan-D, Robitussin Cold and Flu, Vicks Nyquil
    Over-the-counter diet aids with phenylpropanolamine (Dexatrim, Accutrim [note this compound has since been banned for use in the US)
    Over-the-counter nasal sprays (Vicks inhaler, Afrin)
    Asthma medications (Marax, Bronkaid tablets, Primatine Tablets)
    Prescription medications (Amfepramone, Cathne, Etafediabe, Morazone,
    ...phendimetrazine, phenmetrazine, benzphetamine, fenfluramine, dexfenfluramine,
    ...dexdenfluramine,Redux, mephentermine, Mesocarb, methoxyphenamine, phentermine,
    ... amineptine, Pholedrine, hydroymethamphetamine, Dexedrine, amifepramone, clobenzorex,
    ...fenproyorex, mefenorex, fenelylline, Didrex, dextroamphetamine, methphenidate, Ritalin,
    ...pemoline, Cylert, selegiline, Deprenyl, Eldepryl, Famprofazone)

    amphetamines have a lot in common w/ many common stimulents/antihistimines/weight-loss meds and are probably more likely to show up as a false positive than any other drug.
