How Long Does Lorazepam Stay In Your Urine?

How long does lorazepam stay in your urine?
At a glance
- Every person metabolizes lorazepam at a slightly different rate; however it has a half-life of 10-20 hours on average.
Additionally, the primary metabolite has a half-life of about 18 hours.
- It depends on the test itself. If a test was specifically looking for lorazepam or its primary metabolite, it would be detectable for 9-10 days.
Answer
Hi Belinda and thank you for your question.
Every person metabolizes lorazepam at a slightly different rate due to things like genetics, age, kidney function, liver function, etc.
For most adults, I’ve found that it has a half-life of 10-20 hours, or the time it takes your body to metabolize half of the dose.
For example, if you took a 1mg dose of lorazepam and you were a slow metabolizer (it has a half-life of about 20 hours), after 20 hours, 0.5mg would still be in your body.
After another 20 hours, 0.25mg would be in your body. We usually consider a drug to be entirely metabolized after 5-6
