How Long Does Fentanyl Stay In Your System?
In general, and depending on your frequency of opioid use and other factors, fentanyl will remain in your system for 24 to 72 hours.
Fentanyl is one of the most dangerous drugs on today’s market. Although it’s an effective prescription drug for treating chronic pain, the United States has seen a sharp rise in fentanyl overdoses.
Fentanyl Detection Times
Pharmacologists study the elimination half-life of prescription opioids, or the period of time it takes for your body to eliminate or metabolize half of the drug dose. Half life is important for determining how long a substance can be detected on a drug test.
There are a variety of reasons why you may need a drug test. Workplace requirements may include mandatory drug testing or you may have legal obligations to be regularly tested.
Whatever the case may be, you may need to supply a urine test, blood test, or even a hair test to verify that you are drug-free.
Fentanyl is likely to show up on a urine test anywhere between 24 to 72 hours after last use.
Although results may vary based on certain factors, expect fentanyl to show up on a blood test for up to two days after using it last.
Hair tests can detect traceable levels of narcotics long after the substance was last used. For fentanyl, it can show up on a hair test for up to 90 days (three months).
How Fentanyl Works
Fentanyl is a powerful synthetic opioid intended to relieve severe pain. A popular painkiller, this drug is available as a transdermal patch (Duragesic), lozenge, film strip, and tablet. It’s only intended to be used for a short amount of time to relieve pain and discomfort.
This drug is dangerous as it binds to the body’s opioid receptors. These receptors are stored in the area of the brain that controls pain and emotions. After continued use, the body becomes numb to feelings and pain and only derives its sense of feeling from the drug itself.
Side effects of fentanyl may include:
- heightened sense of happiness
- breathing difficulties
Fentanyl Drug Overdose
According to the Centers for Disease Control and Prevention (CDC), more than 56,000 drug-related deaths involved synthetic opioids like fentanyl in 2020.
As a result of the Covid-19 pandemic, there has also been a spike in overdose deaths and overall drug abuse leaving many healthcare institutions and treatment programs working hard to treat this growing issue.
The risk of overdose is increased when you consume too high an amount of the drug itself and your body goes into shock. Your breathing or heart rate may become too slow or stop altogether.
In this extreme case, it may be necessary to immediately administer naloxone in an effort to save someones’ life. Naloxone attaches to the opioid receptors and reverses the effects of the drug on the body.
Fentanyl Addiction Treatment
Due to the potency of fentanyl and the chance of severe withdrawal symptoms, it’s recommended that no one should detox from this drug without the assistance of trained medical professionals.
If you or a loved one is struggling with substance use, it’s important to seek professional support at a substance abuse treatment program.
