Fentanyl: What It Is, Uses, Side Effects & Drug Interactions

The length of time it takes to feel the effects of fentanyl depends on the type you take. Fentanyl isn’t detectable in hair for the first few days after the last use. However, once fentanyl is in the hair, it can be detected for up to 3 months. Fentanyl drug use can’t be consistently detected by drug testing.

If someone takes fentanyl as a tablet, lozenge, or nasal spray, it will usually take effect within minutes. The effects will often wear off in around four to six hours, but the drug can show up in the system for much longer. If someone uses a fentanyl patch, it can take a day or two to begin showing effects, but they last longer. If someone uses fentanyl intravenously, its onset of action can be less than 60 seconds, with peak effects in two to four minutes. This method takes longer to leave the system because it releases very slowly into the body.

Illicitly produced fentanyl is sold alone or combined with heroin and other substances. Subcutaneous absorption through lollipops occurs in the stomach and digestive tract just like swallowing pills does and typically takes the longest to start producing a high effect. From the point of administration, fentanyl spreads through the body into tissues and organ systems.

The drug is absorbed through the mucosal membranes inside the nose and meets the bloodstream soon after. Both snorting and injecting fentanyl generally produce a strong rush that people who misuse fentanyl often enjoy. You don’t have to be a health care professional to give this medication.

Pain patches allow fentanyl to be absorbed through the skin. Transdermal absorption rates are slower to allow for a paced release of the drug over a long period of time, per the National Capitol Poison Center. Since so many people misuse opioid drugs such as fentanyl, many wonder how long it might take to get through withdrawal or pass drug screenings after use. Fentanyl can be easily detected in urine for 24 to 72 hours via an advanced urine drug test1. These long-term dangers are prevalent among individuals with drug abuse issues.

They can continue to show up in a urine screen for one to three days after using it just one time. Also, one of the issues currently facing the United States is the fact that fentanyl is being added to other drugs, including cocaine, MDMA and fake Percocet pills obtained online. Even small amounts of the fentanyl contained in these drugs are fatal and are responsible for a rising amount of overdoses and deaths.

How long it takes to leave the body is also dependent on the method of administration, as well as the metabolism of the individual abusing it. Some people take fentanyl illegally by separating it from skin patches and injecting it. This can be dangerous since it’s hard to judge dose size.

1. Transdermal absorption rates are slower to allow for a paced release of the drug over a long period of time, per the National Capitol Poison Center.
2. This can be dangerous since it’s hard to judge dose size.
3. It is often given to patients post-surgery but has become increasingly popular as a recreational drug, despite becoming illegal due to its addictive properties and high overdose risk.
4. Fentanyl can be detected in urine tests 24 to 72 hours after last use; in blood tests up to 48 hours; and in hair up to three months after last use.
5. When someone uses fentanyl, it breaks down into two metabolites detected in the drug screen.

This results in it taking between 11 to 22 hours before all traces of the medication are out of his system. If one takes more fentanyl in that time, then the half life will restart. Fentanyl is a powerful painkiller, between 50 and 100 times more effective than morphine. It is often given to patients post-surgery but has become increasingly popular as a recreational drug, despite becoming illegal due to its addictive properties and high overdose risk. Hair drug tests are often used in tandem with positive urine or blood tests.

If you unknowingly take fentanyl in another drug, you may overdose, since fentanyl is so potent. Fully recovering from a Fentanyl addiction requires a course of treatment in an inpatient drug rehab.

When ingested nasally, you can feel the effects of fentanyl around the 60-minute mark.

While this is not a 100% safety net, it is one tool that can help prevent an overdose. Pharmaceutical fentanyl is used to treat post-op pain, cancer patients and others with severe chronic pain. The liquid form is often dropped on paper or small candy, leading to the potential for tragic deaths among children. Smoking crushed fentanyl also causes the effects to be felt quite quickly, but it is hard to determine this without controlling for the dose being used.

Fentanyl, even when taken orally, goes through extensive bodily filtering. This drug test detects fentanyl in urine within 24 hours of the last use. Fentanyl remains detectable in the body for up to 72 hours. People who inject the drug will have it coursing through their bloodstream almost immediately.

One should expect another three to five days of detox-related discomfort before they begin to feel better. The substance may already be out of their system, but the body has to learn how to function again without the addictive substance. While often undetected by standard drug tests, an advanced urine drug test can be used to identify fentanyl. In this case, fentanyl can be recognized in urine for eight to 24 hours, depending on various factors including age, weight and more. While urine tests may not recognize fentanyl after a full day, other methods still detect it and the drug can continue to wreak havoc on the body after improper use.

A medically supervised detox program can help you safely and successfully withdraw from fentanyl and other substances. Certain medicines can be used during this time to reduce the severity of your withdrawal symptoms if you’re dependent on opioids.
