Do you want to know how long does fentanyl stay in your body? Or blood, urine, saliva and hair?

We have answers for you and much more but let’s start with the basics fentanyl first!

Fentanyl is a potent synthetic opioid 50 to 100 times stronger than morphine.It is a prescription medication that is also illegally produced and used and is a common recreational drug among the youth. They start taking it for fun, and then the strong addiction never lets them get out of this habit. It is a pain medication that, like morphine, is widely used to treat patients in terrible pain, especially following surgery. It is also used to treat chronic pain patients who have developed a physiological resistance to other opioids. Tolerance occurs when you need a higher and more frequent dose of medication to attain the desired results. In prescription form, fentanyl is marketed under the trade names Actiq®, Duragesic®, and Sublimaze®.

Fentanyl has an addiction potential and its usage among drug addicts has increased in recent years, owing to enhanced and sophisticated techniques of manufacture and the pandemic and isolation.

It may appear strange, but preliminary data from the CDC’s National Centre for Health Statistics show that there were an estimated 100,306 drug overdose deaths in the United States during the 12 months ending in April 2021, a 28.5 % increase from the 78,056 deaths during the same period the previous year.

According to the latest statistics, the expected number of opioid overdose deaths jumped to 75,673 in the 12 months ending in April 2021, up from 56,064 the previous year. In the 12 months ending in April 2021, overdose fatalities from synthetic opioids (mainly fentanyl) and psychostimulants such as methamphetamine also climbed. Cocaine deaths rose, as did natural and semi-synthetic opioid deaths, including prescription pain medication).

This research blog will provide readers with a better understanding of what Fentanyl is and how it affects your body. The blog’s primary focus will be on the most frequently asked questions:

  • How long does fentanyl stay in your system?
  • How long does fentanyl stay in your urine?
  • How long does fentanyl stay in your saliva?

As we move down the page, we will answer the critical questions for you. However, the discussion would be futile or incomplete unless we understand fentanyl half life and its dose. People also want to know how long does fentanyl last? We will provide authentic answers for individuals who wish to stay informed as well as those who have used or been addicted to fentanyl at some time in their lives.

Before we can dispute how long it lingers in your various body fluids, we need to know the fentanyl half life. The half-life of a drug is the length of time it takes for the body to remove half of the amount of substance consumed. This changes depending on the medicine, the route of administration, and the dosage. However, depending on the fluid in question, fentanyl has a half-life of roughly 2 to 4 days. However, it is also dependent on the drug’s mode of delivery.

Let us now address all questions one by one!

How long does Fentanyl Stay in Your System?

According to research, the powdered form and pill have the most potent and most prolonged pathway for the medication to stay in your system since they slowly release and become available for circulation. However, modern means of administration, such as chewable tablets,transdermal patches, nasal sprays, pills, and injectable, can all be utilized by users and will remain in circulation for varying amounts of time. In contrast, illicit fentanyl is often available in powder or tablet form or combination with other drugs.

How long Does Fentanyl Stay in Urine?

Most medications that enter our systems are excreted through the urinary tract since it is the quickest way for the body to get rid of unwanted substances.   A study of seven females who took fentanyl and its variations revealed a 90 % clearance rate after 48 hours of consumption. However, the study also labelled the findings as controlled since the quantity ingested significantly impacts the clearance rate. As a result, it is reasonable to suppose that fentanyl remains in urine for no more than 72 hours. Another aspect to consider is that there are even more powerful modified versions of fentanyl that last longer than 72 hours in urine.

How Long Does Fentanyl Stay in Your Saliva?

Saliva is a complex bodily fluid with several peculiar qualities, and it has long been a subject of drug testing study. So far, research has shown that saliva is an untrustworthy factor in which fentanyl may remain for more than 12 hours. If the delivery method was either oral or nasal, the unreliability worsened. In the case of fentanyl patches, the odds of detection are extremely minimal, if not non-existent. If the medicine is administered through an IV injection, the release is rapid, as is the clearance.

How Long does Fentanyl Stay in Your Blood?

In the case of blood, fentanyl clears quickly, although it can persist for up to 72 hours and becomes minimal after 96 hours. However, this is dependent on the type of fentanyl used, the mode of administration, and the amount consumed. However, it is fair to presume that fentanyl will be eliminated from your body within four days.

How long Fentanyl Can Stay in Hair Samples

Fentanyl and other narcotics have been identifiable in hair root samples even after three months of usage, which is problematic. This is because hair grows slowly yet has a considerably greater preservation rate. So, if a person is about to board a sensitive aircraft and has a history of fentanyl usage, he should be informed that the root hair will not lie even after three months.

Does Fentanyl Show Up on a Drug Test?

Yes! It will appear on a drug test up to 72 hours after the first dosage, but because most drug screens do not detect tiny amounts, it is fair to believe that the four days are the most. However, you should be aware that the hair root test will undoubtedly be a litmus test for you since it may surface on a drug test screen after three months of use.
