Product Overview
Why Test for Xylazine?
Xylazine, sometimes called “tranq,” is a veterinary sedative that is not approved for human use. It may be mixed into fentanyl and other unregulated drugs without the person’s knowledge. Exposure can cause severe sedation, slowed breathing, dangerously low blood pressure, and serious skin wounds.

How Testing Supports Harm Reduction
Harm reduction helps reduce injuries, overdoses, and other health risks associated with substance use. Xylazine test strips provide an additional tool for checking a substance for possible xylazine contamination, helping people make more informed decisions.
These Xylazine (XYL) test strips feature a 500 ng/mL cutoff. Each color pouch contains one test strip and a scoop, with 25 individually packaged tests per box.
Important Testing Limitations
-
A negative result does not guarantee that a substance is safe or free of xylazine.
-
This single-substance test does not screen for fentanyl or other drugs.
-
Results do not determine purity, potency, or a safe amount to use.
-
Follow the manufacturer’s instructions for supported sample types, preparation, testing, and reading results.
For harm reduction use only. Not intended to diagnose a medical condition.
Overdose Awareness
Naloxone (Narcan) does not reverse xylazine’s effects, but it should still be given during a suspected overdose because opioids such as fentanyl may also be present. Call 911 immediately, give naloxone if available, and follow the dispatcher’s instructions.
Someone would test for xylazine to find out whether it has been mixed into a drug without their knowledge. Xylazine, sometimes called “tranq,” is an animal sedative that has been found mixed with fentanyl, heroin, and other street drugs. For More Information Click --> CDC
It matters because xylazine can cause heavy sedation, slowed breathing, dangerously low blood pressure, and serious skin wounds. Combining it with opioids increases the danger. For More Information Click --> FDA
Harm reduction test strips check a sample of the substance before use, helping people identify an unexpected ingredient. A negative result does not mean the substance is safe—test strips can miss the drug. For More Information Click --> CDC
For your website, these strips fit the harm reduction and community outreach category. We should confirm the manufacturer’s instructions before describing which sample types your specific product can test.
One important distinction: Narcan (naloxone) does not reverse xylazine itself, but it should still be given during a suspected overdose because fentanyl or other opioids may also be present. Call 911. For More Information Click --> CDC
