How Long Does Diazepam Stay in Your System?

Detection Timetable Depends on Many Variables

Trying to establish how long diazepam is detectable in the body depends on many variables, including which kind drug test is being used. Diazepam - marketed as Valium and Valrelease - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting diazepam in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time diazepam will show up on a drug test.

How often you take Valium and the strength of the dosage can also play a role in how long in remains in the system.

The following is an estimated range of times, or detection windows, during which diazepam can be detected by various testing methods:

How Long Does Diazepam Stay in Urine?

Diazepam can be detected in a urine test for up to 1-6 weeks

How Long Does Diazepam Remain in the Blood?

Blood tests for Diazepam can detect the drugs for up to 6-48 hours

How Long Can Diazepam Be Detected in Saliva?

A saliva test can detect Diazepam for 1-10 days

How Long Does Diazepam Remain in Hair?

Diazepam, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Prevent Severe Diazepam Side-Effects

Diazepam is used to relieve anxiety, muscle spasms, and seizures and to manage alcohol withdrawal symptoms.

Serious side-effects of Diazepam can be avoided by knowning how long in remains in the system, so that the dosage is not repeated too quickly.
