Hi Frankie,
If this is in regards to drug testing, information I've gathered states that Fentanyl can be detected in your urine for up to 8-24 hrs after your last dose.
-It can be detected in your blood for up to 12 hours after your last dose.
-It can be detected in your saliva for up to 1-2 days after your last dose.
-It can be detected in your hair for up to 90 days after your last dose.
Hopefully this info can give you a rough estimate of how long the drug remains in various parts of your system (at least at a detectable level).
Has anyone else experienced different time frames for getting Fentanyl out of your system, other than what's noted above?
