Fentanyl is a synthetic opioid, significantly more potent than morphine, primarily used for pain management, especially in severe or chronic conditions. It's prescribed in forms like patches, lozenges, and injections. Due to its high potency, fentanyl carries a significant risk of addiction and overdose, even in small quantities. It's also illicitly manufactured and mixed with other drugs, increasing the risk of accidental overdoses....


Who would benefit from testing fentanyl?

Testing for fentanyl is crucial for patients prescribed the drug for pain management, to ensure compliance and detect potential abuse. It’s also important in addiction treatment centers, for workplace drug testing in safety-sensitive jobs, and in legal settings like DUI cases. Emergency medical personnel may also test for fentanyl in cases of suspected overdose or when treating unknown substance intoxication.

How long does fentanyl stay in your system?

Fentanyl can be detected in urine for up to 3 days after use, in blood for up to 48 hours, and in saliva for up to 1-3 days. In hair follicle tests, fentanyl can be detected for months after use. These timeframes can vary based on individual metabolism, frequency of use, and the amount used.

How long after use should you take the test?
