What is fentanyl?
Fentanyl is a highly potent synthetic opioid. Doctors sometimes prescribe fentanyl for severe pain—often after surgery or for advanced cancer—but it remains addictive.
Illicit versions of fentanyl can be 50 times stronger than heroin and 100 times more potent than morphine. More recently, illicit fentanyl drove a nationwide surge in overdose deaths. It's sometimes mixed into other drugs, like heroin, counterfeit prescription pills, or even methamphetamine. Since it's so potent, it can lead to overdose, even among people with high tolerance.
Just how dangerous is fentanyl?
In 2023, fentanyl and other opioids were involved in about 70% of all U.S. overdose deaths. Data from early 2024 showed a glimmer of hope: a sharp drop in fentanyl-related deaths. Still, the risk remains high, particularly in communities where street fentanyl is readily available, and the potency of a single dose can be unpredictable.
Overdose after relapse
Because fentanyl is so potent, the risk of overdose is present even for people who believe they "know their limit." A single lapse after a period of abstinence can become fatal due to lost tolerance. This makes relapse one of the most dangerous moments in the recovery process.
Co-occurring mental health
Fentanyl use is also closely linked to co-occurring mental health conditions such as depression, anxiety, PTSD, and trauma-related disorders. Many people use opioids to numb emotional pain, which can intensify withdrawal symptoms and increase relapse risk without professional support. Integrated detox and mental health screening are critical for long-term stability.
If you or your loved one is at risk, acting quickly can save a life.

Fentanyl withdrawal symptoms & timeline
Once someone stops using fentanyl, they'll experience withdrawal symptoms. Their symptom severity will depend on how long they've used and how high their tolerance is.
Opioid withdrawal symptoms fall into two categories:
Physical symptoms
Mental & emotional symptoms
Severe muscle, joint, and bone pain
Anxiety and agitation
Nausea, vomiting, diarrhea
Depression or deep sadness
Sweating, chills, goosebumps
Intense cravings
Headaches and fatigue
Restlessness
Dilated pupils
Insomnia
Elevated heart rate or blood pressure
Brain fog and difficulty concentrating
Fentanyl withdrawal symptoms set in more quickly and are more severe than those of other opioids, like heroin. Without 24/7 support during detox, it can be easy to relapse.
Medical detox timeline: What to expect
At our licensed drug detox facility in Colorado, clients receive 24/7 medical monitoring, comfort medications, hydration support, and sleep stabilization. When clinically appropriate, medication-assisted treatment (MAT) may begin during detox.
Short-acting opioids, like fentanyl, usually take a week to 10 days to fully clear from the body. For many people, symptoms usually come in a couple of waves.
Early withdrawal (8–24 Hours)
The first day after stopping fentanyl use brings on flu-like symptoms, like runny nose and eyes. Sweating, yawning, and sleep loss are also normal. Joint, muscle, and headaches also usually set in quickly. Cravings also start early.
Full withdrawal (24–72 Hours)
Symptoms peak within the first three days for most people detoxing from fentanyl. Blood pressure and heart rate usually rise. Some people feel agitated and even get a fever. Nausea, diarrhea, and vomiting make it hard to eat or drink, which can cause dehydration. For some, blood pressure can drop.
The first month
People who had a severe addiction to fentanyl can experience discomfort for a few weeks. As time goes by, physical symptoms become less intense, which makes cravings—which also diminish—easier to cope with.
Post-acute withdrawal syndrome (PAWS)
Some people experience PAWS, though not everyone does. PAWS symptoms can last for a few months as the brain and body adjust to life without opioids. It usually involves less intense but persistent symptoms like:
- Mood instability
- Difficulty with memory or focus
- Sleep disturbances
- Periodic cravings
- Increased stress sensitivity
PAWS is a significant factor in relapse—ongoing therapy and participation in support groups can help manage this stage.
Medically supervised fentanyl detox methods
A medical detox for fentanyl provides safety, comfort, and structure during withdrawal. Because fentanyl acts quickly and powerfully, professional monitoring reduces complications and relapse risk.
Inpatient detox programs
Our inpatient detox program in Aurora provides:
- 24/7 medical oversight: Nurses and doctors are always on-site, able to immediately address severe symptoms like dehydration or cardiac changes.
- Structured routines: Daily schedules include medication times, meals, hydration schedules, periodic health checks, and support groups.
- Therapeutic activities: Evidence-based methods are available to process trauma, identify triggers, and prevent relapse.
- Dual diagnosis screening: Assessments to identify any co-occurring mental health conditions, which contribute to addictive behaviors.
- Transition planning: As symptoms subside, a counselor helps identify the next steps, whether that’s inpatient rehab, intensive outpatient care, or another type of treatment.
- Medications for opioid use disorder (MOUDs): FDA-approved medications like Subutex, methadone, and Suboxone can help manage cravings, making it easier to focus on recovery
After detox, many clients transition directly into our inpatient addiction treatment program for continued stabilization.
Medication-assisted treatment for fentanyl addiction
MAT, or medication-assisted treatment, greatly reduces cravings for fentanyl. When someone has fewer cravings, they're less likely to relapse during detox. Medication-assisted treatment is not just replacing one addiction with another; it's a controlled, therapeutic, tapered approach to withdrawal management.
Common medications used
MAT is a standard opioid use disorder treatment, especially for fentanyl addiction. It blends medication to control withdrawal and cravings with therapy and educational support for a holistic approach.
Medications include:
- Buprenorphine: Reduces withdrawal symptoms and blocks the “high” from other opioids.
- Methadone: Replaces illicit opioids with a safe, regulated dose administered in a clinic. Daily administration and the clinic structure help taper the dose down over time.
- Buprenorphine/naloxone (Suboxone): Buprenorphine reduces withdrawal symptoms, and naloxone blocks the effects of other opioids if used.
Benefits of medication-assisted treatment
- Improved retention: Staying on an MAT plan lowers overdose and all-cause mortality risk.
- Craving control: Medication reduces physical discomfort and suppresses cravings, allowing individuals to focus on therapy and life rebuilding.
- Support for recovery: MAT is most effective when paired with counseling, life skills coaching, housing assistance, and employment support. States with broad MAT access and naloxone distribution have seen the largest drops in fentanyl-related deaths.
At Sheridan Grove Recovery, MAT plans are carefully created, monitored, and adjusted by medical professionals. Our clinicians work with you to develop a personalized plan—adjusting medications to fit both your withdrawal experience and long-term goals.
Managing withdrawal and preventing relapse
Withdrawal management takes more than just medication and medical monitoring. When you stop using fentanyl, your brain and body take time to adjust. You'll need to learn new habits and coping skills to avoid relapse.
Withdrawal management strategies
During detox, your comfort and safety are our top priorities. We use a comprehensive strategy to help you manage all your symptoms:
- Hydration: Nurses monitor your fluid intake and provide electrolyte drinks to combat dehydration—a major risk during withdrawal.
- Nutrition: Our kitchen serves small, protein- and vitamin-rich meals. We offer food that's easy on the stomach to minimize nausea and provide needed energy.
- Movement and rest: Gentle movement (like short walks) helps reduce muscle pain, while rest is encouraged to allow your body to fully heal.
- Comfort measures: Warm showers, relaxation and grounding techniques, and breathwork help manage stress and agitation.
- Sleep support: Non-habit-forming sleep aids, a quiet environment, and sleep hygiene routines help restore sleep patterns disrupted by withdrawal.
Relapse prevention techniques
Relapse prevention begins in detox and remains crucial long after withdrawal subsides. Personalized relapse prevention plans at Sheridan Grove Recovery include:
- Trigger identification: You’ll work with clinicians to recognize situations, people, or emotions that could spark cravings. Proactive planning helps you harness avoidance or coping strategies.
- Coping skills: Practice deep breathing, mindfulness, journaling, or creative expression as outlets for stress and anxiety.
- Peer support: Early participation in support groups and regular check-ins with counselors reinforce positive changes and provide a sounding board for difficult moments.
- Emergency plans: Together, we develop crisis plans including trusted contacts, emergency phone numbers, and safe spaces in case of strong urges to use.
Comprehensive fentanyl addiction treatment
Fentanyl detox isn't the last step in recovery. Comprehensive treatment helps support every part of your life after addiction.
Harm reduction approaches
Not everyone is ready for complete abstinence immediately, and harm reduction can be a life-saving bridge to recovery. For those not ready to enter treatment, Colorado provides harm reduction services like:
- Naloxone distribution: Free Narcan spray kits can reverse overdoses
- Fentanyl test strips: Supplies to test substances for fentanyl contamination, potentially preventing accidental overdose
Syringe access programs: Safe syringe exchange reduces the risk of HIV, hepatitis, and soft tissue infections
Dual diagnosis and co-occurring disorders
Many people living with fentanyl addiction also experience depression, anxiety, trauma, or PTSD. Treating these co-occurring disorders alongside addiction is crucial.
- Integrated care: Mental health professionals and addiction specialists collaborate for assessment, diagnosis, and joint treatment planning.
- Evidence-based therapies: Options include cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), trauma-informed care, and medication management as needed.
Substance abuse counseling and support groups
Clients are encouraged to participate in a mix of counseling and peer support:
- Individual therapy: Sets goals, builds trust, processes trauma, and develops personalized recovery strategies.
- Group therapy: Provides a sense of belonging, reduces isolation, and enhances communication skills.
- Community support groups: Resources like Narcotics Anonymous (NA), SMART Recovery, and faith-based recovery groups are available to sustain healing beyond treatment.
Overdose prevention and naloxone use
How to respond to an overdose:
- Call 911 immediately. Most states, including Colorado, have “Good Samaritan” laws to protect you and the victim from prosecution for seeking help.
- Administer naloxone (Narcan). Use a Narcan kit (usually a nasal spray) according to the directions on the box.
- Perform rescue breathing if the person is not breathing or only gasping, aiming for 1 breath every five to six seconds.
- Place them in the recovery position (on their side) once they start breathing, and stay with them until help arrives.
Prevention tips:
- Carry naloxone: Many states require pharmacies to stock it with little or no co-pay, especially under Medicaid.
- Don’t use alone: Encourage “never use alone” practices; hotlines and check-ins can save lives.
- Test your supply: Fentanyl test strips can detect contamination and help people who use drugs make safer choices.
