Fentanyl is a type of synthetic opioid that was designed for the treatment of severe pain. It also produces a pleasant euphoria that makes it very addictive.
Because fentanyl is addictive, it can be very difficult and uncomfortable when a person tries to stop taking it. Many times, people continue using fentanyl simply to avoid withdrawal.
When detox and withdrawal are conducted at a specialized detox center or treatment facility, the chances for success are much greater.
A professional detox treatment program ensures that medical help is always available, making withdrawal from fentanyl addiction safer and more comfortable.

What Is Detoxification From Fentanyl?
Detoxification is the process of eliminating fentanyl from a person’s system completely while abstaining from further use of fentanyl.
There are multiple ways for a person to achieve this, but the end goal is always to be completely sober from fentanyl and all other opioids.
Why Is Fentanyl Detox Necessary?
Fentanyl is a dangerous drug to be addicted to because it poses a very high risk of overdose. The longer a person uses fentanyl, the higher their risk for fentanyl overdose.
While it is possible for a person to quit using fentanyl suddenly, or “cold turkey,” this method does not have a high success rate and can be very dangerous.
Instead, a medical detox program allows for safe withdrawal either under constant supervision or at a person’s convenience — whichever is best for them.
The Stages Of Fentanyl Detox
The three stages of fentanyl withdrawal are early, peak, and long-term. Long-term withdrawal is also known as post-acute withdrawal syndrome (PAWS).
The early stage of detox begins between six and 12 hours after the last dose of fentanyl was taken. Withdrawal symptoms generally start as somewhat mild and grow in intensity over time.
The worst symptoms of withdrawal are felt during the peak phase of detox, which usually begins about two days after the last dose of fentanyl. This phase is when relapse is most likely.
Long-term withdrawal begins after physical withdrawal symptoms subside. During this time, a person may still experience mild psychological symptoms of fentanyl withdrawal.
For most people, long-term withdrawal will only last for a few weeks. In some cases, however, it can turn into PAWS.
Why Opioid Addiction Leads To Withdrawal
When someone is addicted to opioids, they are dependent on them in order to feel normal in their everyday lives.
Without opioids, they may feel physically ill and mentally agitated. They will also likely experience very strong cravings to use opioids again.
Once someone has developed an opioid use disorder, they may find themselves in a constant cycle of active opioid use and withdrawal.
How Common Fentanyl Withdrawal Symptoms Are Treated
Opioid withdrawal symptoms can be very uncomfortable, but they can be treated with opioid replacement therapy.
These types of medications activate opioid receptors and can mimic the effects of fentanyl, while allowing a person to be weaned off the drug at a comfortable rate.
Common symptoms of fentanyl withdrawal may include:
- runny nose
- muscle aches and pains
How Life-Threatening Fentanyl Withdrawal Symptoms Are Treated
Withdrawal symptoms from fentanyl are rarely considered to be life-threatening.
A person may develop complications such as dehydration, however, from excessive vomiting or diarrhea during withdrawal. This can be treated with intravenous fluids and electrolytes.
Strong cravings can be life-threatening if they lead to continued fentanyl abuse, as a person is at higher risk for overdose if their tolerance has been brought down through detox.
Someone who is going through opioid detox should plan to have naloxone, the opioid overdose antidote, on hand in the event of relapse and overdose.
Top Fentanyl Detoxification Treatment Methods
While it is possible for a person to go through detox on their own, it is not recommended. This is especially true for a drug like fentanyl, which poses a high risk of overdose.
It is much safer to go through the detox process under the supervision of healthcare providers.
Medical detox usually happens within an inpatient or residential treatment setting and can last anywhere from a few days to a couple of weeks.
This detox method uses medications to help ease the symptoms of opioid withdrawal, allowing a person to get through this difficult period safely and comfortably.
One of the biggest benefits of this method is that the person going through withdrawal has constant medical supervision in case any problems arise during detox.
Drug tapering involves decreasing the dose of a medication gradually over time, giving a person’s body and brain time to adjust between each decrease in dosage.
This type of detox is usually done under the guidance of a medical professional and can take up to several months to complete.
Medication-Assisted Treatment (MAT)
Medication-assisted treatment (MAT) uses the opioid replacement medications methadone and buprenorphine to help ease a person through the withdrawal period.
Naltrexone is also a medication used in the treatment of opioid addiction, however, a person must be completely detoxed from opioids before using it.
This type of treatment can be done at an outpatient substance use treatment center and usually lasts several weeks to several months.
Post-Detox Addiction Treatment For Fentanyl
As beneficial as detox is while overcoming addiction, it is only the very first step in the recovery process.
After detox has been successfully completed, it is a good idea for anyone overcoming an addiction to fentanyl to continue their recovery in either an inpatient or outpatient center.
Other treatment options for opioid addiction may include:
- behavioral therapy
- individualized treatment plans
- peer support groups
- medication management
- dual diagnosis treatment
- case management
- aftercare and relapse prevention support
