Valium is a brand-name benzodiazepine. Its generic name is diazepam. Valium is used primarily for the treatment of anxiety but can be used for other symptoms and conditions as well.

You may wonder how long does Valium stay in your system and this is a relevant question for a few different reasons. First, there is the potential to overdose if you take too much Valium or you combine it with another central nervous system depressant. If you are going to undergo a drug screening, you may wonder how long Valium stays in your system. That determination can be important if you’re dependent on Valium and you are figuring when withdrawal symptoms could begin.

What is Valium?

What is Valium and what is it used for? Valium is a benzodiazepine, which means it’s a central nervous system depressant. Valium has a calming effect on the brain and central nervous system, so it’s a short-term treatment for anxiety. Other reasons someone might take Valium include for alcohol withdrawal syndrome, seizures, sleep problems and restless leg syndrome. Valium isn’t meant to be a long-term treatment for conditions like anxiety and insomnia because it has side effects and long-term use can lead to addiction and dependence.

Valium Half-Life

The half-life of a substance is the time it takes to reduce to half of the original value. It usually takes several half-lives for a drug to leave the system fully.

The elimination half-life for Valium is relatively long, ranging from 30 to 56 hours, and 43 hours on average. Based on the Valium half-life it can take nearly ten days for a dose to leave the system fully. Metabolites can be left behind as Valium is processed, and those can be detected in some drug screenings.

How Long Does Valium Stay in Your Urine?

One of the most common types of drug tests is a urine test. Factors such as hydration and health play a role in how long Valium stays in your urine. Generally, Valium may stay in your urine for anywhere from one to six weeks after using it.  

How Long Does Valium Stay in Hair?

Hair follicle tests aren’t common ways to screen for substance use, but they do have the longest detection windows compared to blood, urine and saliva tests. It can take a few days for Valium use to initially show up in a hair follicle test, but once it does, it can be detected for up to 90 days after use.

How Long Does Valium Stay in Saliva?

If someone’s saliva is tested, the use of Valium might show up anywhere from one to 10 days after use.

How Long Does Valium Stay in Blood?

Blood tests can be used to determine if someone is using certain substances. So, how long does Valium stay in your blood? The detection window for Valium in a blood test is usually the shortest. Valium use may show up in blood anywhere from six to 48 hours after someone uses it, on average.

Getting Treatment for Valium Abuse

Since Valium is a prescription medication, many people use it as instructed. However, that usage can turn into addiction and dependence. Valium abuse can lead to negative side effects and can increase the risk of a fatal overdose, especially if it’s combined with other central nervous system depressants.
