Benzodiazepines, commonly known as benzos, are a class of prescription medications primarily used to manage anxiety, seizures, insomnia, and muscle spasms. Brands like Xanax, Ativan, Valium, Klonopin, and Restoril are frequently prescribed in the USA. These medications work by slowing down the central nervous system, producing a calming effect. A common question for individuals prescribed these medications, or those concerned about substance use, is: How Long Do Benzos Stay In Urine?
This article provides a detailed overview of benzodiazepine detection windows, focusing on urine tests, and explores the various factors that influence how long these substances remain detectable in your system. Understanding these factors is crucial for anyone undergoing drug testing, managing benzodiazepine use, or seeking information about substance detection timelines.
Benzodiazepines can be detected in various bodily fluids and tissues, including urine, blood, hair, and saliva. Urine drug tests are the most common method for detecting benzos due to their accuracy and relatively long detection window. The duration benzos remain detectable in urine varies depending on the specific type of benzodiazepine, dosage, frequency of use, and individual metabolic factors.
Benzodiazepine Detection Times in Urine: A Detailed Look
Here’s a breakdown of the typical detection times for common benzodiazepines in urine:
1. Xanax (Alprazolam) Detection in Urine
Xanax, the brand name for alprazolam, is a short-acting benzodiazepine often prescribed for anxiety and panic disorders. If you’re wondering, how long does Xanax stay in urine?, it’s generally detectable for:
- Urine: 3 to 7 days after the last dose.
- Blood: 1 to 2 days.
- Hair: Up to 90 days, depending on hair length.
- Saliva: Up to 2.5 days.
2. Ativan (Lorazepam) Detection in Urine
Ativan, containing lorazepam, is another commonly prescribed benzodiazepine used for anxiety, seizures, and insomnia. For Ativan, the detection window in urine is typically:
- Urine: 3 to 6 days.
- Blood: 6 to 8 hours, potentially longer with regular use.
- Hair: Up to 90 days.
- Saliva: 8 hours to 3 days.
3. Valium (Diazepam) Detection in Urine
Valium, known generically as diazepam, is a longer-acting benzodiazepine used for anxiety, muscle spasms, and alcohol withdrawal. How long does Valium stay in your urine? The detection window is generally:
- Urine: 3 to 7 days.
- Blood: 6 to 48 hours.
- Hair: Up to 90 days.
- Saliva: 1 to 10 days.
4. Klonopin (Clonazepam) Detection in Urine
Klonopin, or clonazepam, is a long-acting benzodiazepine prescribed for panic disorder, seizures, and social anxiety. The typical urine detection time for Klonopin is:
- Urine: 5 to 7 days.
- Blood: 1 to 3 days.
- Hair: Up to 90 days.
- Saliva: 1 to 4 days.
5. Restoril (Temazepam) Detection in Urine
Restoril, containing temazepam, is primarily used to treat insomnia. For Restoril, the urine detection window is generally:
- Urine: 3 to 7 days.
- Blood: 1 to 3 days.
- Hair: Up to 90 days.
- Saliva: 1 to 3 days.
It’s important to note that these are estimated ranges. Individual detection times can vary.
5 Key Factors Influencing Benzodiazepine Detection Time
Several factors can influence how long benzos stay in your system and, consequently, their detection time in urine and other tests. These factors include:
-
Age: Older individuals typically have slower metabolic rates and reduced kidney and liver function, which can prolong the time benzodiazepines remain in their system.
-
Kidney Function: Impaired kidney function can affect the elimination of certain benzodiazepines, like lorazepam and chlordiazepoxide, leading to longer detection times.
-
Liver Function: The liver is crucial for metabolizing benzodiazepines. Liver dysfunction can slow down the breakdown process, extending the duration benzos stay in the body, particularly for benzodiazepines like chlordiazepoxide, diazepam, and lorazepam.
-
Dosage: Higher doses of benzodiazepines generally take longer to be eliminated from the body compared to lower doses.
-
Frequency of Use: Chronic or frequent benzodiazepine users will typically have a buildup of the substance in their system, resulting in longer detection times compared to occasional users. A single dose will be eliminated much faster.
These factors highlight that benzodiazepine elimination is a highly individual process. While general detection windows exist, the exact timeframe can vary significantly from person to person. The concept of half-life is also important to understand. After approximately five half-lives, a drug is considered to be almost completely eliminated from the body. Benzodiazepines have varying half-lives, which contributes to the different detection windows.
Types of Drug Testing for Benzodiazepines
Benzo rehab centers and medical facilities utilize various drug testing methods to detect benzodiazepines. Here are the common types:
-
Urine Testing: This is the most frequently used method due to its accuracy and ability to detect benzos for several days after use. Urine tests identify benzodiazepine metabolites that are filtered through the kidneys.
-
Saliva Testing: Saliva tests offer a less invasive option and are most accurate within hours of benzodiazepine use. They have a shorter detection window compared to urine tests.
-
Hair Testing: Hair follicle tests can detect benzodiazepine use for a much longer period, up to 90 days or even longer depending on hair length. However, hair testing is less common for detecting recent use and more suited for looking at long-term patterns.
-
Blood Testing: Blood tests provide accurate detection within a few days of benzodiazepine use. However, they are more invasive and expensive than urine or saliva tests, making them less common for routine screening.
-
Perspiration Testing (Sweat Testing): This is the least common method and is sometimes used in parole or probation cases for long-term monitoring. Results can take up to two weeks.
Benzodiazepine Addiction Treatment Options
For individuals struggling with benzodiazepine addiction, effective treatment options are available. A comprehensive approach to treatment often includes:
a. Medical Detoxification
Medical detox is often the first step in benzodiazepine addiction treatment. It provides 24/7 medical supervision to manage withdrawal symptoms safely and comfortably as the body clears the benzodiazepines. Benzodiazepine withdrawal can be dangerous and should always be managed under professional medical care.
b. Residential Rehab (Inpatient Rehab)
Residential or inpatient rehab provides a structured environment for individuals to focus on recovery after detox. Patients reside at the treatment facility and participate in therapy, counseling, and educational sessions to develop coping mechanisms and strategies for a benzo-free life.
c. Outpatient Rehab
Outpatient rehab offers more flexibility, allowing individuals to live at home and attend treatment sessions at the facility. This option is suitable for those with less severe addiction or as a step-down from residential treatment. Outpatient programs can also include telehealth services for added convenience.
d. Aftercare Programs
Recovery is an ongoing process. Aftercare programs provide continued support and resources after completing rehab. These programs may include support groups, relapse prevention planning, and ongoing therapy to help individuals maintain long-term sobriety.
e. Dual Diagnosis Treatment
Many individuals struggling with benzodiazepine addiction also have co-occurring mental health disorders. Dual diagnosis programs address both addiction and mental health conditions simultaneously, providing integrated treatment for holistic recovery.

- Fenoprofen (Nalfon)
It’s essential to inform drug testing facilities about any medications you are taking to avoid misinterpretations of test results.
Where Are Benzodiazepines Metabolized?
Benzodiazepines are primarily metabolized in the liver. Liver enzymes break down these drugs through various metabolic pathways, facilitating their elimination from the body via urine. This metabolic process is a key factor in determining how long benzodiazepines remain detectable.
Do Different Benzo Types Have Different Detection Times?
Yes, absolutely. As detailed above, different types of benzodiazepines have varying half-lives and metabolic pathways, which directly impact how long they remain detectable in urine and other body fluids. Short-acting benzos like Xanax generally have shorter detection windows than longer-acting ones like Valium or Klonopin.
Which Benzo is Longest Acting and Which Has the Shortest Half-Life?
Flurazepam is considered one of the longest-acting benzodiazepines, while triazolam has one of the shortest half-lives among commonly prescribed benzos. Half-life is a crucial factor in determining the duration of drug effects and detection times.
How Long Can You Test Positive for Benzos?
The duration you can test positive for benzodiazepines varies, but generally, urine tests can detect benzos for several days after the last dose, and hair follicle tests can detect use for up to 90 days or longer. Factors like the specific benzo, frequency of use, and individual metabolism play significant roles in the detection window.
