How long does ativan (lorazepam) stay in your urine?

It depends: Medications are taken up into the body, reach a level, and are broken down and then excreted by the liver and the kidney. Drug studies define the usual uptake and elimination rates for normal adult animals under normal conditions (half life). Patients on high doses with poorly functioning kidneys can keep medication around for a long time. For others, rapid elimination occurs. For you?
