Hi Ema: Ativan (brand name for lorazepam) is excreted from the body in the urine and the feces (stools). According to the first website below, 95% of the drug is excreted within 120 hours, or five days, mainly in the urine (88%), so it should still be detectable in the urine after 5 days. Lorazepam is a type of benzodiazepine. According to the second website below the detection period in the urine for benzodiazapines in general is 3 - 7 days.
