Do benzos show up on a 5-panel drug test?

Worried about whether your prescription anxiety meds might trigger a testing alarm? You’re not alone. In this guide, we’ll break down the science behind benzodiazepine detection, explain how standard panels work, and give you actionable tips to prepare for a screening.

Understanding Benzodiazepines and Drug Testing

Benzodiazepines (often called “benzos”) are a class of medications prescribed for anxiety, insomnia, and seizure disorders. But do benzos show up on a drug test? In short, yes—but it depends on the type of test and the substances included in its panel.

Standard workplace screens often use immunoassay technology, which can pick up benzos at certain concentration thresholds. Positive results are typically sent for confirmation via GC-MS (gas chromatography–mass spectrometry), which is highly specific.

How long do benzos show up on a drug test?

Detection windows vary by benzo type, dosage, metabolism, and test method. Generally:

• Urine tests can detect most benzos for 2–7 days after last use.
• Hair tests may show benzodiazepines for up to 90 days.
• Blood and saliva tests have shorter windows—usually 1–2 days.

Are benzodiazepines part of a standard panel? (do benzos show up on a 5 panel drug test)

A typical 5-panel drug test screens for:

• THC (marijuana)
• Cocaine
• Amphetamines (including meth)
• Opiates
• PCP

Notice benzodiazepines aren’t on that list by default. So do benzos show up on a 5-panel drug test? Only if the test is expanded to a 6- or 7-panel that explicitly includes them.

If you need to know which employers test for benzos specifically, our Companies That Drug Test resource can help you prepare in advance.

Klonopin and Other Prescriptions: do klonopin show up on drug test as a benzo?

Klonopin (clonazepam) is one of the most commonly prescribed benzos. In a targeted benzodiazepine screen, assays will flag metabolites like 7-aminoclonazepam, confirming the presence of Klonopin and related compounds.

So yes, if your lab orders a benzodiazepine panel, do klonopin show up on drug test as a benzo? Absolutely—and typically for up to 5 days in urine.

Tips to Cleanse and Prepare for a Drug Test

Whether you have a prescription or are worried about accidental exposure, here are a few strategies to support your body’s natural elimination pathways:

• Hydration: Drinking plenty of water helps dilute urine, though labs often check for over-dilution.
• Exercise: Light cardio can boost metabolism, but avoid extreme workouts right before testing.
• Detox Supplements: Proprietary blends like herbal cleanses and vitamin-rich formulas may aid liver and kidney function. Browse our Detox Drinks collection for options.
• Timing: Plan your test when you’re at the far end of your detection window—usually 5–7 days after your last dose.

Conclusion

To recap, do benzos show up on a 5-panel drug test? Not unless your employer requests an expanded panel that includes them. Yet in a dedicated benzodiazepine screen, medications like Klonopin will register for several days. Understanding detection windows and testing methods can help you plan intelligently.
