how long does valium stay in your body
A doctor may want to make sure you don't have traces of Valium in your system before prescribing another medication. Valiumâor rather metabolites associated with the medicationâcan be detected in different ways. It will show up in blood for six to 48 hours and in urine for one to six weeks after being taken. A saliva test can detect Valium one to 10 days after it's taken. And like many other drugs Valium can be detected with a hair follicle drug test for up to 90 days.
