Fentanyl is a highly potent synthetic opioid. Detoxing from fentanyl without clinical support and supervision can be dangerous, especially if you have a fentanyl addiction.
Fentanyl is an opioid drug also prescribed as:
Fentanyl detox is highly recommended for anyone who’s taken prescription fentanyl for a long time, or has misused fentanyl in its prescribed or illicitly manufactured forms.
Dangers Of Fentanyl Detox
Do not stop taking fentanyl all at once. If you’ve been taking fentanyl for more than a few weeks, this could cause symptoms of fentanyl withdrawal.
Detoxing from fentanyl can be dangerous in part due to withdrawal symptoms, but also due to a risk of relapse without medical support and accidental overdose after detox.
Risk Of Overdose With Fentanyl Detox
Fentanyl is a potent drug. It’s about 50 times as powerful as heroin, an illicit opiate. After detoxing from fentanyl, your tolerance for fentanyl will be reduced.
What does this mean? This means your body won’t react to it the same way if you try to take the same amount of fentanyl that you did prior to detox.
Instead, this could overwhelm the body and result in drug overdose. Overdose deaths involving fentanyl have increased in recent years, and detox is a risk factor for this.

Risk Of Relapse With Fentanyl Detox
Relapse to fentanyl use after detox is a major concern among those seeking to overcome fentanyl abuse or addiction.
This is, in part, why medical detox programs are recommended. Relapse after fentanyl detox, or during the detox process, could result in accidental overdose.
With a detox program, there’s a reduced risk of relapse, in part because an inpatient environment can physically separate you from fentanyl and other addictive substances.
Is Fentanyl Withdrawal Dangerous?
Opioid withdrawal is not typically life-threatening. Symptoms of fentanyl withdrawal can be mild to severe in nature and may cause you to feel very physically sick.
Some withdrawal symptoms, however, can be dangerous if they are not properly treated, or if you attempt to detox outside of a supportive care environment.
Potential dangers of fentanyl withdrawal include:
- severe dehydration: Side effects of detox, such as vomiting, diarrhea, and sweating can cause dehydration. Without replenishing, this could become serious.
- electrolyte imbalances: Excessive vomiting and diarrhea can deplete the body of essential vitamins and minerals. This could cause life-threatening electrolyte imbalances.
- exacerbated health conditions: Fentanyl withdrawal may worsen or exacerbate other medical and mental health conditions.
Withdrawal may cause changes in blood pressure, heart rate, and breathing rate. Without treatment, cravings for fentanyl can also become very strong during detox.
Fentanyl Detox And Withdrawal Symptoms
If you’re physically dependent on fentanyl, you may begin to experience withdrawal symptoms within hours of taking your last dose.
Common early signs of withdrawal include:
- teary eyes
- runny nose
- muscle and bone pain
- excessive yawning
- trouble sleeping
Within the first few days, additional symptoms of withdrawal may begin to set in. These can grow more intense over the first three to four days, before beginning to decline.
Late withdrawal symptoms may include:
- hot and cold flashes
- dilated pupils
- fast breathing
- stomach cramps
- drug cravings
Protracted Withdrawal After Fentanyl Detox
Protracted withdrawal is a syndrome that can develop in some people who detox from fentanyl after developing severe drug dependence.
Protracted withdrawal, also known as post-acute withdrawal syndrome, is identified by withdrawal symptoms that last beyond the first one to two weeks of detox.
Common signs of protracted withdrawal after fentanyl detox include:
- drug cravings
- mood swings
Protracted withdrawal may last months or years. This can be treated with substance abuse treatment services such as medication-assisted treatment (MAT) and behavioral therapy.
Who Needs Fentanyl Detox?
Fentanyl detox is recommended for anyone who’s become dependent on prescription fentanyl products or illicit forms of fentanyl—including illicit drugs laced with fentanyl.
- people who have taken prescription fentanyl for more than a few weeks
- people who misuse fentanyl
- people who have become addicted to fentanyl
- people who misuse fentanyl in combination with other drugs (e.g. heroin)
Fentanyl detox services are offered by many detox facilities and inpatient treatment centers in the U.S. that offer treatment for the abuse of fentanyl and addiction.
Treatment For Fentanyl Detox
Do not try to detox from fentanyl alone. This could lead to life-threatening outcomes without a robust support system.
Treatment for fentanyl detox may be offered through a medical detox program, or an inpatient rehab center that offers opioid detox services for people with drug addiction.
Medical Detox For Fentanyl Addiction
Medical detox is the safest way to detox from fentanyl. This is an inpatient detox program that can offer medical treatment, monitoring, and 24-hour clinical support.
Benefits of medical detox include:
- reduced risk of relapse
- 24-hour medical supervision
- offers treatment for withdrawal symptoms
- can offer referrals for drug rehab at a nearby treatment facility
Medications For Fentanyl Detox And Withdrawal
Medical detox programs may offer certain medications for treating fentanyl withdrawal symptoms and preparing individuals for an addiction treatment program.
Medications that can help during fentanyl detox:
- methadone: Methadone is a long-acting opioid agonist and maintenance medication that can reduce drug cravings and the severity of withdrawal.
- buprenorphine: Buprenorphine, also known as Subutex or Suboxone, is a partial opioid agonist that can reduce drug cravings and help prevent relapse.
- naltrexone: Naltrexone is an opioid antagonist that can reduce cravings for fentanyl and alcohol. It may be induced after acute withdrawal.
- clonidine: Clonidine can help relieve symptoms of withdrawal, such as pain, nausea, anxiety, vomiting, and diarrhea.
- lofexidine: Lofexidine, also known as Lucemyra, is a non-opioid medication that can also help relieve opioid withdrawal symptoms, including high blood pressure.
Medication for co-occurring disorders may also be provided during medical detox to ensure patient safety and prevent complications.
