Any medicine may persist in the body for 4-5 times its elimination half life after the last dose taken. The elimination half life of Diazepam is 20-50 hours.
So after the last dose I am looking at 250 hours after the last dose?
although a lot also depends on other factors like body weight, duration of use, physical condition but in most cases the drug is completely flushed out from the body within 10-14 days if we consider its elimination half life of 20-40 hours.
OK, thank you.
