In fact, Ativan can be detected in urine up to 6 weeks after it was last taken in a heavy user. But even small doses might be detectable in standard drug screens up to a week later. More here on Ativan detection and use, plus a section at the bottom for your questions about Ativan in your system.
Ativan is a short acting benzodiazapine (valium, xanax, klonopin, restoril, are all benzos.)

I'd say about 24-48 hours depending on how much Ativan you are taking.
