Valium duration of action. The half-life of Valium is 20 hours, sometimes longer. It reaches peak levels in the blood just 1-1.5 hours after being taken. Despite taking several days to leave the body, the effects wear off within 4-6 hours, so it does need to be taken throughout the day. Valium time in the body. How long does diazepam stay in your system? Valium (diazepam) can stay in the body for weeks and can be detected for at least 3 weeks in urine. In some users, Valium may take 6 weeks to completely clear from the body.
In order to find out exactly how long it stays in your body, you have to look at its elimination half-life. The elimination half-life of valium is anywhere from 30 to 56 hours with the average time being 43 hours. This means that it takes that time to clear only half of the last dose you took so even after that time you still have 50 percent of the drug remaining in your system.
