How Long Does Fentanyl Stay in Your System?
Fentanyl is a powerful analgesic medication that is primarily prescribed to treat severe and chronic pain, though it is often also abused for recreational purposes. Fentanyl is part of a class of drugs called opioids, which activate naturally occurring opioid receptors in the brain.
It is important for anyone taking regular or pharmaceutical fentanyl to understand that the effects of the drug last far longer than the high it provides. Different routes of administration result in varying half-lives. Dosage also affects how long fentanyl stays in the system; different fentanyl patch strengths can cause people to withdraw at different rates.
No matter what dosage a person is withdrawing from, fentanyl withdrawal is generally arduous, dangerous, and requires medical supervision.

How Long Does a Fentanyl Stay in Your System?
Most drug tests are designed to detect opioids in the body. A fentanyl test kit or fentanyl urine test can measure fentanyl specifically. People take drug tests for a number of reasons. Some are regularly required by their employers to take drug tests.
Others take drug tests during legal proceedings or because their physicians are trying to determine if they are taking the correct dose of their medication. No matter what reason one is taking a test, one should understand that fentanyl can be detected long after the high has worn off.
Factors that affect how long fentanyl remains in the body include the strength of the dosage, how long a person was taking fentanyl, frequency of use, body weight, and general health. In general, however, an advanced drug test can detect fentanyl up to 24-72 hours after the last dose was taken.
Even after that, however, traces of fentanyl remain detectable in the body. Norfentanyl, a broken down metabolite of fentanyl, remains detectable in urine for 96 hours. Hair tests, while more labor-intensive than urine tests, can be used to detect fentanyl use even up to three months after use.

Fentanyl Withdrawal Timeline
- The first 24 hours: Most people begin experiencing cravings and mild withdrawal symptoms
- Between 36 and 72 hours after the last dose: At this point, most people begin experiencing the peak of fentanyl withdrawal symptoms. Their symptoms will be at their most intense and debilitating, and their cravings will also be most intense. This is the period during which most people relapse.
- Between day 5 and 8: The most severe withdrawal symptoms tend to dissipate at this time. Most people continue to experience withdrawal symptoms, but they will also begin to feel more normal and functional.
- The following weeks and months: It is common for people to experience mild fentanyl withdrawal symptoms long after quitting. These include physical symptoms, like increased sensitivity to pain, as well as psychological symptoms like depression and irritability. When these symptoms last for many months, it is a sign of post-acute withdrawal syndrome (PAWS).
