Benzodiazepines, commonly known as benzos, are a class of prescription medications primarily used to treat anxiety, insomnia, seizures, and muscle spasms. These drugs work by slowing down the central nervous system, producing a calming effect. Commonly prescribed benzos include Xanax, Ativan, Valium, Klonopin, and Restoril. Understanding how long these substances remain detectable in your body is crucial for various reasons, including drug testing, medical procedures, and managing potential dependence.
This article will explore the detection windows for benzodiazepines in different bodily fluids and the factors that influence how long benzos stay in your system.
Benzodiazepine Detection Times: A Detailed Overview
Benzodiazepines can be detected through various drug tests, including urine, blood, hair, and saliva tests. The detection window varies depending on the specific benzo, the type of test, and individual factors. Here’s a breakdown of the typical detection times for some commonly prescribed benzos:
1. Xanax (Alprazolam) Detection Times
Xanax, a fast-acting benzodiazepine, is frequently prescribed for anxiety and panic disorders. Its detection times are relatively short compared to longer-acting benzos.
Xanax Detection in Urine
Urine tests can detect Xanax for approximately 3 to 7 days after the last dose. This is a common and reliable method for benzo detection.
Xanax Detection in Blood
Blood tests have a shorter detection window for Xanax, typically around 1 to 2 days following the last dose. Blood tests are less common for routine benzo detection due to the shorter timeframe.
Xanax Detection in Hair
Hair follicle tests offer a longer detection window, potentially detecting Xanax for up to 7 days after the last use, depending on the length of the hair sample. However, hair tests are less frequently used for detecting recent benzo use.
Xanax Detection in Saliva
Saliva tests can detect Xanax for up to 2.5 days after the last dose. Saliva testing offers a less invasive alternative to urine testing with a slightly shorter detection window.
2. Ativan (Lorazepam) Detection Times
Ativan is another commonly prescribed benzodiazepine used for anxiety, seizures, and insomnia. Its detection times are slightly different from Xanax.
Ativan Detection in Urine
Ativan is typically detectable in urine for 3 to 6 days after the last use, similar to Xanax.
Ativan Detection in Blood
Blood tests can detect Ativan for a shorter period, usually around 6 to 8 hours post-administration. Regular users may have a slightly longer detection window in blood.
Ativan Detection in Hair
Hair follicle tests can detect Ativan for an extended period, up to 90 days after the last use. This makes hair testing effective for detecting past, but not necessarily very recent, Ativan use.
Ativan Detection in Saliva
Saliva tests can detect Ativan for approximately 8 hours to 3 days following the last dose, bridging the detection window between blood and urine tests.
3. Valium (Diazepam) Detection Times
Valium is a longer-acting benzodiazepine used for anxiety, muscle spasms, and alcohol withdrawal. Its detection times are generally longer than Xanax and Ativan.
Valium Detection in Urine
Urine tests can detect Valium for a longer duration, typically 3 to 7 days after the last dose, similar to Xanax and Ativan, but potentially longer in chronic users due to its longer half-life.
Valium Detection in Blood
Valium can be detected in blood for 6 to 48 hours after the last dose. The longer end of this range applies to regular or high-dose users.
Valium Detection in Hair
Similar to other benzos, Valium can be detected in hair follicle tests for up to 90 days after the last dose, depending on hair length.
Valium Detection in Saliva
Saliva tests can detect Valium for a relatively wide range, from 1 to 10 days after the last dose, depending on individual metabolism and usage patterns.
4. Klonopin (Clonazepam) Detection Times
Klonopin is a long-acting benzodiazepine primarily used for panic disorder, seizures, and social anxiety. Its longer half-life results in extended detection windows.
Klonopin Detection in Urine
Urine tests can detect Klonopin for a longer period, generally 5 to 7 days after the last dose.
Klonopin Detection in Blood
Blood tests can detect Klonopin for 1 to 3 days after the last dose, a shorter window than urine but still relevant for recent use detection.
Klonopin Detection in Hair
Hair follicle tests can detect Klonopin for up to 90 days, consistent with the long detection window offered by hair testing.
Klonopin Detection in Saliva
Saliva tests can detect Klonopin for 1 to 4 days following the last dose, offering a detection window between blood and urine.
5. Restoril (Temazepam) Detection Times
Restoril is prescribed for insomnia and has a shorter to intermediate half-life compared to Valium or Klonopin.
Restoril Detection in Urine
Urine tests can detect Restoril for 3 to 7 days after the last use, a common detection window for many benzodiazepines.
Restoril Detection in Blood
Blood tests have a shorter detection window for Restoril, typically 1 to 3 days after the last use.
Restoril Detection in Hair
Hair follicle tests can detect Restoril for up to 90 days, similar to other benzos, making it useful for retrospective detection.
Restoril Detection in Saliva
Saliva tests can detect Restoril for a shorter period compared to urine, generally 1 to 3 days after the last use.

Factors Influencing How Long Benzos Stay in Your System
Several factors can influence how long benzodiazepines remain detectable in your system. These include:
- Age: Older individuals typically metabolize medications more slowly, which can extend the detection window for benzos.
- Kidney Function: Impaired kidney function can slow down the elimination of certain benzos, like lorazepam and chlordiazepoxide, leading to longer detection times.
- Liver Function: The liver plays a crucial role in metabolizing benzos. Liver impairment can prolong the presence of benzos like diazepam, chlordiazepoxide, and lorazepam in the system.
- Dosage: Higher doses of benzodiazepines take longer to be eliminated from the body, extending the detection window.
- Frequency of Use: Chronic benzo users will generally have longer detection times compared to infrequent users due to drug accumulation in the body. Single doses are eliminated more quickly.
These factors highlight that benzo detection times are estimations and can vary significantly from person to person. The elimination half-life of a benzodiazepine, the time it takes for the body to eliminate half of the drug, is a key determinant of detection time. After approximately five half-lives, a drug is considered to be nearly eliminated from the body.
Types of Benzodiazepine Drug Testing
Benzodiazepine drug testing utilizes various methods to detect the presence of these substances. The most common types of drug tests used in benzo rehab centers and other settings include:
- Urine Testing: This is the most common and frequently used method for benzodiazepine detection. Urine tests are accurate for detecting benzo metabolites for several days to weeks after use.
- Saliva Testing: Saliva tests offer a less invasive method and are most accurate for detecting recent benzo use, typically within hours to a few days of ingestion.
- Hair Testing: Hair follicle drug tests provide the longest detection window, capable of detecting benzo use for up to 90 days. However, they are less common for detecting very recent use.
- Blood Testing: Blood tests offer accurate detection within a shorter timeframe, typically a few days after use. They are more invasive and expensive than urine or saliva tests.
- Perspiration Testing: Perspiration testing is the least common method and is primarily used for long-term monitoring, such as in parole cases. Results can take up to two weeks to process.
Benzodiazepine Addiction Treatment Options
For individuals struggling with benzodiazepine addiction, various treatment programs are available:
a. Medical Detoxification
Medical detox provides 24/7 medical supervision during the withdrawal process. Benzodiazepine withdrawal can be dangerous and uncomfortable, making professional medical detox crucial for safe and effective withdrawal management.
b. Residential Rehabilitation
Residential rehab, or inpatient rehab, offers a structured environment for intensive addiction treatment after detox. Patients reside at the facility and participate in therapy, counseling, and support groups to develop coping mechanisms and relapse prevention strategies.
c. Outpatient Rehabilitation
Outpatient rehab programs allow individuals to live at home while attending treatment sessions at a facility. This option is suitable for those with less severe addictions or as a step-down from residential rehab. Telehealth services may also be available for added convenience and accessibility.
d. Aftercare Programs
Aftercare programs provide ongoing support following rehab. These programs may include support groups, therapy, and relapse prevention planning to help individuals maintain long-term sobriety and navigate life without benzodiazepines.
e. Dual Diagnosis Treatment
For individuals with co-occurring mental health disorders alongside benzo addiction, dual diagnosis programs offer integrated treatment. These programs address both the addiction and the underlying mental health condition simultaneously for comprehensive recovery.
