Hi there,

Thanks for your query.

Zolpidem, cyclobenzqprine, adderall, topiramate, Escitaplopram, Lamotrinine, Trazadone, Diphenhydramine are excreted in urine and hence test POSITIVE.


Alprazolam, bupropion, Zolpidem, and lithum are excreted in urine as well as by liver. Hence, Urine will test POSITIVE only if the amount of drug in urine is above the critical level at which the test becomes POSITIVE.

Fexofenadine - only 10% of the drug is excreted in urine. Urine will test POSITIVE ONLY if present above the critical level.

If you find my response helpful and informative, do not forget an “excellent” (5-stars") rating to my answer, to ENCOURAGE & MOTIVATE all doctors- engaged in social service- to render sound advice to the FREE queries.


Fond regards and have a nice day
