Hello,The only problem reported with Cetirizine HCl tablets is when it is combined with pseudoephedrine hydrochloride as in Zyrtec-D. Pseudoephedrine may cause a false positive for amphetamines. However, Zyrtec on it's own should not cause any false positives.Let me know if you have any other questions. If not, please don't forget to leave a positive rating as that's the only way I get credit for answering your question. Thank you.
