Fentanyl is a potent opioid drug prescribed to treat breakthrough cancer pain in patients who are already tolerant to other pain medications.1 It is highly addictive, and chronic use can lead to physical dependence. Unpleasant withdrawal symptoms can occur when a person decides to quit using.

Risks of Withdrawal
Fentanyl withdrawal syndrome is rarely life-threatening. Withdrawal can sometimes have serious side effects or complications, though these are rare.
- Aspiration: Some people who are in withdrawal may first pass out and, at some point later, vomit. This may result in choking or breathing stomach contents into the lungs (aspiration), which can lead to infection.4
- Dehydration: Severe diarrhea and vomiting can also result in dehydration and electrolyte imbalances,4 which can lead to fainting and serious complications if not treated.
- Relapse and overdose: Another danger of withdrawal is a relapse. When a person stops using fentanyl, his or her tolerance decreases. If a person begins using fentanyl again, even in smaller doses than usual, overdoses are more likely to occur since the person’s tolerance has been greatly reduced.4
Fentanyl Withdrawal Timeline
- 6-12 hours after the last dose: Withdrawal symptoms begin. Early symptoms include anxiety, muscle aches, insomnia, runny nose, and sweating.
- 2-4 days: The peak of withdrawal effects usually occurs. Symptoms include stomach cramps, diarrhea, nausea, and vomiting.
- 5-7 days: Symptoms usually dissipate within a week.4,5
Certain post-acute withdrawal symptoms, such as cravings, mood swings, and sleep disturbances, may continue for weeks or even months after fentanyl use has stopped.5
Withdrawal is difficult and uncomfortable, with bone pain being quite severe, in addition to nausea and vomiting being hard to endure. Many people who try to withdraw from fentanyl on their own struggle to manage the symptoms without professional help. Relapse is common.

Fentanyl is an opioid medication. Like all opioids, it can be addictive because it acts on the reward centers of the brain. Many people experience a “rush” or euphoria from fentanyl, which serves as positive reinforcement for continued use and abuse.2
Continued fentanyl use can lead to tolerance, or the need to take increased doses to achieve the same or desired effects.2 A person who develops tolerance may take fentanyl more frequently or in larger doses to feel euphoria or pain relief. This practice can be particularly dangerous, since fentanyl is 100 times more potent than morphine.3
Over time, the body adapts to the presence of fentanyl, and the person becomes physically dependent. A person can be dependent without exhibiting drug-seeking behaviors. However, someone who is physically dependent on fentanyl will experience uncomfortable and unpleasant withdrawal symptoms if they try to cut back or stop using the drug.2
Treatment for Withdrawal
Fortunately, many detox and treatment programs are available to help someone quit fentanyl. Professional treatment can help to alleviate uncomfortable, physical symptoms and provide emotional support while detoxing from the drug.
Detox is designed to help a person make it through the initial stages of withdrawal. However, recovery from addiction is a lifelong battle and does not end when the person completes detox. If the issues that led to the addiction are not addressed, it is likely that a person will begin using fentanyl or other drugs when faced with stress or unwanted emotions.
Most programs, whether inpatient or outpatient, provide a combination of individual or group therapy, medical assessments, frequent evaluations of a person’s medical needs, and medication management. Many inpatient programs offer detox, and some outpatient programs offer it as well.
The counseling provided in a treatment program can provide a person with:
- Coping strategies.
- Stress-management skills.
- Sober social skills.
- Drug education.
- Aftercare or relapse prevention plans.
Examples of fentanyl addiction treatment programs are as follows:
- Detox centers: Detox programs can be the first step to achieving sobriety. A detox center can provide medical oversight and supportive counseling services to people seeking recovery from a fentanyl addiction. Detox programs are short-term, and people typically transfer into an inpatient or outpatient recovery program once the program has been completed.
- Inpatient: Inpatient rehab treatment requires that a person live at the recovery center for the duration of the program. It provides 24-hour care and support and allows the person to escape everyday stressors and drug-using environments.
- Outpatient: Outpatient rehab treatment is often a step down from an inpatient program. These programs provide ongoing support and counseling to a person in recovery, but allow them the freedom to live at home. This option is beneficial for those who are reluctant or otherwise unable to take the time off work or school to enter a residential treatment program. Some programs may provide services for several hours a day, 5 days a week, while others may consist of 1-2 hours of treatment a day, for 1-3 days per week.
- Partial hospitalization: This is an intensive outpatient program that typically meets several hours per day. Many people who complete an inpatient program may transfer to a partial hospitalization program as part of an aftercare plan.
Medications for Withdrawal
Medications can make withdrawal easier and more comfortable.
Medications can make fentanyl detox and withdrawal easier and more comfortable. Some people stay on these medications for an extended period of time, while others taper off of them in a few weeks.
- Methadone has been used as a substitute for fentanyl. It can ease the fentanyl withdrawal process and is particularly helpful for those who have a high level of opioid tolerance (as most fentanyl users do).5
- Buprenorphine can be used to mimic fentanyl’s effects on the opioid receptors in the body, which helps to reduce withdrawal symptoms and cravings for fentanyl.5
- Suboxone is another form of buprenorphine that also contains a medication called naloxone.6 Suboxone cannot be abused, because if a person injects it, he or she will experience serious withdrawal symptoms.6
- Clonidine: can be used to treat certain symptoms of withdrawal, such as anxiety, cramping, sweating, and runny nose. 4,5
