how long does valium stay in your system?

i’ve read a bunch of things, how long?

Answer:

Are you talking about how long it works or how long it is detectable?

A single use of Valium (diazepam) is typically detectable (in urine) for 7-10 days

Diazepam has a half-life of 20-60hrs however diazepam breaks down into multiple active metabolites, particularly desmethyldiazepam (nordazepam). The average half-life of nordazepam is 30-100hrs.

If you are talking about how long Valium works then it is typically about 4-6hrs.

    The elimination half life ranges from 50 hours to 100 hours, sometimes longer. Since it takes at least 7 half lives to be below the cut-off, you’re looking at 15-30 days average.
