Treatment for Fentanyl Addiction

You cannot see or taste fentanyl in a pill or powder. Naloxone can reverse most overdoses. Medicines for opioid addiction are the core of care.

Key takeaway

CDC describes fentanyl as a synthetic opioid up to 50 times stronger than heroin and 100 times stronger than morphine. NIDA says the addiction is treatable with methadone, buprenorphine, or naltrexone. Naloxone can reverse most overdoses and then wears off. If someone will not wake or has stopped breathing, call 911.

You can follow every warning you have heard and still not know what is in the pill. That uncertainty is the fear, and it is a property of the supply, not a failure of nerve. CDC describes fentanyl as a synthetic opioid made in a laboratory, up to 50 times stronger than heroin and 100 times stronger than morphine, and a major contributor to fatal and nonfatal overdoses in the United States. NIDA says the illegally made kind is a main driver of the overdose crisis, and that addiction to it is still a treatable medical condition.

If someone will not wake, is breathing slowly, or has stopped breathing, call 911 and give naloxone if you have it. For a mental health crisis, call or text 988.

The name covers two different drugs

Doctors prescribe pharmaceutical fentanyl for severe pain, especially after surgery and for advanced cancer. CDC says most recent fentanyl overdoses are linked to illegally made fentanyl, sold for a heroin-like effect and often mixed into other drugs because it is so potent. That mix makes drugs cheaper, stronger, and more dangerous.

Illegally made fentanyl shows up as powder or liquid. Powder is commonly mixed with heroin, cocaine, and methamphetamine, and pressed into pills meant to look like prescription opioids. NIDA adds that counterfeit pills sold as pain medicine, or as medicine for anxiety or ADHD, may contain fentanyl in deadly amounts. The person taking the pill often does not know.

You cannot see, taste, or smell that mix. Test strips can help, usually within about five minutes, and a negative result is not a guarantee. Strips might miss more potent fentanyl-like drugs, such as carfentanil. The sample you test may not be the part that contains fentanyl. CDC also flags xylazine, a non-opioid sedative increasingly found with fentanyl. That mix can be life-threatening. Give naloxone if an opioid may be involved. More on that sedative is in xylazine mixed with fentanyl. After the emergency, naloxone and supplies are covered in harm reduction.

Why a small amount can stop breathing

Fentanyl is much more potent than morphine or heroin, and its effects can start more quickly. Like other opioids, it slows the parts of the brain that control breathing. A dose higher than the body can handle can slow breathing to a life-threatening level. NIDA, citing a DEA fact sheet, says as little as 2 milligrams, about a few grains of salt, can be fatal.

People who do not usually take fentanyl are at particular risk, because their bodies are not used to an opioid that strong. Combining drugs on purpose, or without knowing, raises the chance of serious harm or death. CDC's fentanyl facts page, drawing on mortality data from 2018 to 2021, says synthetic opioids like fentanyl contribute to nearly 70 percent of overdose deaths. That figure describes those years. It is not a promise about this month's local supply. Do not assume a pill or a powder is what the seller called it.

Naloxone first, then the emergency department

If you think someone is overdosing, give naloxone or nalmefene if you have it. Try to keep the person awake and breathing. Both come as nasal sprays a bystander can carry. Naloxone is available over the counter, without a prescription.

Standard-strength naloxone still reverses fentanyl in most people who overdose, even though fentanyl is more powerful than many other opioids. Some overdoses need a second standard dose or a higher-strength product. SAMHSA describes naloxone as a temporary treatment. Its effects do not last long, so a person can slip back into overdose when it wears off. Waking up does not mean you cancel the ambulance. Overdose-reversal medicines do not reverse a benzodiazepine-only or stimulant-only overdose. They are still the right step when opioids may be mixed in. The signs, and what to do while you wait, are on overdose and naloxone.

Medication is the treatment, not a pledge to suffer

Repeated fentanyl use changes brain activity. People can keep using despite harm. Dependence means the body has adapted, so stopping brings withdrawal. Tolerance means the same dose does less, so people take more. A plan that only "gets through the kick" and then sends someone back to the same supply is unfinished. Even a small amount can be fatal, and a dose that used to be familiar can be too much after a break.

The FDA-approved medicines for opioid use disorder are methadone, buprenorphine, and naltrexone. Lofexidine is approved for withdrawal symptoms. It is not a substitute for those three as treatment of the disorder. What each medicine does is on medication for opioid use disorder. When a person takes methadone or buprenorphine as prescribed, the medicine does not produce the same intense high as illegal opioids. Naltrexone is not addictive. None of that is permission to share, stockpile, or start a medicine a friend was given.

Methadone for opioid use disorder comes only from approved opioid treatment programs. Many clinicians can prescribe buprenorphine outside those programs, including by telehealth. Naltrexone is not an opioid. Starting it usually means stopping other opioids first, often for 7 to 10 days, or the medicine may itself cause withdrawal. That timing belongs to a clinician. The setting question is in detox at home versus medical care. Ask whether a program continues medication. A building that bans it is a mismatch for many people with opioid use disorder.

Where the care can sit

Fentanyl addiction is a chronic condition. Treatment can include medication and behavioral therapy. The setting might be an opioid treatment program, an office, or residential or hospital care when withdrawal, pregnancy, or an unstable place to live needs more structure. FindTreatment.gov is the public directory. Filter for medication, then call and ask who prescribes.

Pregnancy does not remove the treatment. NIDA says medications for fentanyl addiction are safe and effective in pregnancy and can improve outcomes for the mother and the baby. Say so on the first call. Treatment during pregnancy has the rest of that conversation. Paying for the medicine is a separate question from whether it works. The limits on that card are in Medicaid and rehab.

Call or text (800) 653-9376 if you are trying to find opioid treatment that continues medication, and ask who prescribes before anyone travels.

Common Questions

How strong is fentanyl compared with other opioids?

CDC says fentanyl is up to 50 times stronger than heroin and 100 times stronger than morphine. NIDA says even a small amount can cause a fatal overdose, including when it was mixed into another drug without the person knowing. Pharmaceutical fentanyl and illegally made fentanyl are both synthetic opioids. You cannot tell them apart by looking at a powder or a pill.

Can naloxone reverse a fentanyl overdose?

NIDA says standard-strength naloxone still works for most people who overdose on fentanyl. Some people need a second standard dose or a higher-strength product. Naloxone and nalmefene are temporary. The person can slip back into overdose when the medicine wears off. Call 911 even if they wake up, and stay with them.

What medicines treat fentanyl addiction?

NIDA says medications are the standard treatment. The FDA-approved medicines for opioid use disorder are methadone, buprenorphine, and naltrexone. Lofexidine is approved for withdrawal symptoms, which is not the same as treatment of the disorder. Do not start, share, or stop any of them from a webpage. Ask a clinician who can prescribe.

Are methadone and buprenorphine just replacing fentanyl?

NIDA says that when methadone or buprenorphine is taken as prescribed for opioid use disorder, it does not cause the same intense high as illegal opioids, which makes these medicines less addictive in that use. Naltrexone is not addictive. That is not permission to share a friend's prescription or to stop on your own.

Can you tell that a pill contains fentanyl by looking at it?

No. CDC and NIDA both say you cannot see, taste, or smell fentanyl mixed into another drug. Test strips can miss fentanyl-like drugs such as carfentanil, and a negative strip on one sample does not prove the rest of the bag is safe. If someone will not wake or is not breathing, call 911.
