Naloxone/naltrexone are robust opioid antagonists that function by blocking µ-receptors. The use of fentanyl citrate injection with CYP3A4 inducers or stopping the CYP3A4 inhibitor will require close and repetitive monitoring of the patient. If the patient has used a monoamine oxidase inhibitor in the previous 14 days, fentanyl is contraindicated. This article focuses on injectable fentanyl; more detailed coverage of the transdermal formulation is available in the StatPearls specific article on transdermal fentanyl. The transdermal patch is for the long-term management of pain. Biochemically, it is a Mu-selective opioid agonist.
- Dealers may sell it as a standalone drug or as a counterfeit for another drug (like oxycodone).
- Once you’ve been taking fentanyl for a while, your body gets used to it and stopping can be very hard.
- These strips can be a useful harm reduction tool for people who drugs.
- However, this is not a reliable indicator of whether a person is taking real fentanyl or not.
Overdose Risk
Opioid medication enters the brain and binds to opioid receptors, restricting pain signals and causing relaxation (Oesterle, 2021). Fentanyl is a synthetic opioid that can be prescribed by doctors for pain management (National Institute on Drug Abuse NIDA, 2021). In the second decade of the 21st century in the United States, fentanyl was one of the deadliest drugs of abuse.
Medical Uses
Alcohol and other drugs (ie, cocaine, heroin) can synergistically exacerbate fentanyl’s side effects, creating multi-layered clinical scenarios that can be complex to manage. When users think they are purchasing heroin and instead actually receive fentanyl, it can often result in overdose deaths. However, an emergency medicine called naloxone can reverse an opioid overdose related to fentanyl.
The Typologies Report

Opioids are a class of drugs that include both prescription medicines such as morphine and illegal drugs like heroin. The opioid epidemic in the United States is largely fueled by drugs smuggled from Mexico; approximately 98% of fentanyl entering the U.S. comes from Mexico. In 2023, a California police union director was charged with importing synthetic opioids, including fentanyl and tapentadol disguised as chocolate.
Treating Fentanyl Addiction

Fentanyl should only be prescribed by doctors who are experienced in treating pain in cancer patients. The risk that you will develop breathing problems may be higher if you are an older adult or are weak or malnourished due to disease. Your doctor will monitor you carefully during your treatment. If this drug is used in countries other than the U.S., it is essential that the manufacturers’ labeling be consulted for more recently available information. Because this drug is no longer available in the US market, the material in this monograph is no longer updated.
Introducing Data Fabric
- Carfentanil, a fentanyl analog, has an additional methyl ester group attached to the 4 position.
- In 2023, a California police union director was charged with importing synthetic opioids, including fentanyl and tapentadol disguised as chocolate.
- Synthetic opioids like fentanyl contribute to nearly 70% of overdose deaths.3 Even in small doses, it can be deadly.456 Over the last few years, nonfatal and fatal overdoses involving fentanyl have continued to rise.457
- Powdered fentanyl looks just like many other drugs.
Its primary clinical use is in pain management for cancer patients and those recovering from surgery. His research focuses on crimes enabled by cryptoassets and emerging technologies, including fraud, money laundering, terrorist financing and illicit activity on the dark web. Our Research and Investigations Team also focuses on identifying new ways vendors use to disguise the trade of such illicit goods. Elliptic has amassed a comprehensive dataset of crypto wallets used by fentanyl dealers to facilitate this deadly trade. This emphasizes how, in this instance, the transparency of cryptoassets can be used to identify activity that illicit actors may have gone to great lengths to conceal. The Elliptic Investigator graphs shown above underscore these capabilities – allowing any associations between dark web markets or vendors with fentanyl suppliers to be unearthed with ease.
Fentanyl Potency
The program connects people who buy illicit opioids with a nurse who helps them determine a fentanyl prescription and dosage that will suit their needs. A harm-reduction organization in Vancouver is helping people addicted to opioids buy pharmaceutical-grade fentanyl at street prices as an alternative to the illicit drug supply—a first in North America. To prevent accidental fentanyl overdoses, you can use fentanyl test strips to ensure other drugs don’t contain the opioid. Fentanyl is not only much stronger than other opioids, but it’s often added to illicit drugs without people knowing.
Forms Of Fentanyl
There were rapid increases in overdoses involving heroin starting in 2010, which the CDC considers the second wave, but synthetic opioids – primarily fentanyl – took over around 2013. While both are synthetic opioids, IMF is responsible for the skyrocketing incidence of fentanyl overdose deaths. But more than 150 people die every day from overdoses related to synthetic opioids like fentanyl, according to the U.S. Some groups provide fentanyl test strips so that users can test drugs for fentanyl and hand out naloxone to prevent deaths from overdose.
Signs Of Fentanyl Addiction
While some urine drug screens can detect fentanyl, others do not. Death can follow quickly if the overdosed person isn’t treated. These test strips can show if fentanyl is present in a drug prior to use. There is no way to tell how much fentanyl might be present in a particular street drug.

Buprenorphine partially activates opioid receptors to ease withdrawal and cravings without producing a significant high. Professional detox programs significantly reduce the risk of relapse and life-threatening complications. The first step in recovery is often medically supervised detox. While fentanyl withdrawal is rarely life-threatening, it can lead to serious complications that need attention. With the right support and coping strategies, you can learn to manage these urges without returning to fentanyl use. Cravings can persist long after physical withdrawal symptoms fade.
This can raise their risk of serious or even deadly pregnancy complications. Research has found that pregnant women with untreated addiction may be less likely to get regular prenatal care. It can also lead to tolerance, which means that the person’s body responds less and less to the drug. Dependence can cause extremely unpleasant withdrawal symptoms if the person stops using it. They are only able to feel normal when they take the drug.

When people overdose on fentanyl, their breathing can slow or stop. Medications for opioid addiction work on the brain by interacting with the same receptors that opioids affect and causing different effects. Mixing fentanyl with any drug is risky, but some drugs pose a serious danger if you take them alongside fentanyl. The U.S. Drug Enforcement Administration estimates more than 258,000 people died from fentanyl overdose between 2013 and 2021. Fentanyl is in a class of drugs called opioids.
Fentanyl can also cause serious health problems and even death from overdose.7 Like other opioids, fentanyl affects the parts of the brain that control breathing. Mixing with other drugs or disguising as a pharmaceutical makes it difficult to determine the correct treatment in the case of an overdose, resulting in more deaths. Fentanyl is contributing to an epidemic of synthetic opioid drug overdose deaths in the United States. Fentanyl, a synthetic opioid and prescription medication renowned for its potency, is employed in medical settings to manage severe pain.
