Xylazine Withdrawal vs Opioid Withdrawal: What’s the Difference?
Experiencing withdrawal after using fentanyl or xylazine? Talk to a DevotedDOc physician today.
As xylazine becomes more common in the illicit drug supply, many people are discovering that withdrawal can be more complicated than opioid withdrawal alone. Because xylazine is frequently mixed with fentanyl, individuals often experience symptoms from both substances after they stop using them. This overlap can make it difficult to determine which drug is causing certain symptoms and why traditional opioid treatments do not always provide complete relief.
Understanding xylazine withdrawal vs opioid withdrawal is important because the two conditions affect the body differently. While they share some symptoms, they involve different biological pathways and may require different treatment strategies. Recognizing these differences can help patients and healthcare providers make more informed decisions about withdrawal management and recovery.
According to the Penn Center for Addiction Medicine and Policy, opioid withdrawal may begin before xylazine withdrawal or the two may occur simultaneously, particularly in people who regularly use fentanyl contaminated with xylazine. The overlap can make withdrawal more difficult to recognize and may complicate decisions about treatment.

What Causes Xylazine Withdrawal and Opioid Withdrawal?
Although xylazine withdrawal vs opioid withdrawal symptoms may appear similar at first, they occur for different reasons because the two substances affect different systems within the body.
Opioid Withdrawal Occurs when Opioid Receptors are No Longer Activated
Opioid withdrawal develops after a person who has become physically dependent on opioids suddenly reduces or stops using them. As opioid levels decrease, the brain and nervous system react to the loss of opioid receptor stimulation, producing symptoms such as muscle aches, nausea, diarrhea, sweating, yawning, dilated pupils, anxiety, and intense cravings.
According to StatPearls, opioid withdrawal is uncomfortable but is generally not life-threatening when managed appropriately. Medications such as buprenorphine (Suboxone) and methadone are well-established treatments for opioid withdrawal and opioid use disorder.
Xylazine Withdrawal Affects a Different Part of the Nervous System
Unlike opioids, xylazine does not act on opioid receptors. Instead, it is an alpha-2 adrenergic agonist that suppresses activity within the sympathetic nervous system. When someone who has developed dependence suddenly stops using xylazine, the body may experience a rebound increase in sympathetic activity, leading to symptoms that differ from traditional opioid withdrawal.
Current evidence suggests that xylazine withdrawal may involve anxiety, irritability, restlessness, elevated heart rate, increased blood pressure, sweating, and other signs of autonomic instability. Because xylazine affects different receptors than opioids, medications that successfully treat opioid withdrawal may not fully relieve symptoms caused by xylazine itself.
Why Both Types of Withdrawal Often Occur Together
Today, xylazine is rarely used alone. It is most commonly found mixed with fentanyl and other illicit opioids, often without the person’s knowledge. As a result, many individuals stop using both substances at the same time, causing xylazine and opioid withdrawal together.
This overlap makes withdrawal more difficult to evaluate because many early symptoms—such as anxiety, agitation, and restlessness—can occur with either condition. Healthcare providers must consider the entire clinical picture rather than assuming every symptom is caused by opioid withdrawal alone.
How xylazine withdrawal differs from opioid withdrawal
The main difference between xylazine withdrawal and opioid withdrawal is the system each substance affects. Opioids act on opioid receptors, while xylazine affects alpha-2 adrenergic receptors. Because of this, the two withdrawal syndromes can overlap without responding to the same medications in the same way.
Opioid Withdrawal Commonly Causes Flu-Like and Gastrointestinal Symptoms
Opioid withdrawal often produces a recognizable group of symptoms, including:
- Muscle and joint pain
- Nausea and vomiting
- Diarrhea and stomach cramps
- Sweating and chills
- Runny nose and watery eyes
- Yawning
- Dilated pupils
- Goosebumps
- Insomnia
- Strong opioid cravings
The timing depends on the opioid involved. Withdrawal from short-acting opioids may begin within several hours, while fentanyl withdrawal can take longer to become obvious and may last longer than withdrawal from heroin or some prescription opioids.
Xylazine Withdrawal May Cause Stronger Autonomic Symptoms
Xylazine withdrawal can also cause anxiety, restlessness, sweating, and agitation. However, it may be more likely to produce signs of rebound nervous system activity, such as:
- Elevated blood pressure
- Rapid heart rate
- Severe restlessness
- Irritability
- Tremors
- Difficulty sleeping
- Persistent anxiety or distress
These symptoms may begin within several hours after the last exposure, although the exact timeline is still not fully understood. Research on human xylazine withdrawal remains limited, so healthcare providers often rely on the patient’s history, symptoms, vital signs, and response to treatment.

Opioid Medications May Not Relieve Xylazine Symptoms
One important clinical difference is how symptoms respond to opioid medications. Buprenorphine, methadone, or other opioid agonists may reduce opioid withdrawal symptoms, but they do not directly treat xylazine withdrawal.
Penn CAMP notes that xylazine withdrawal may be suspected when symptoms such as agitation, anxiety, elevated blood pressure, or rapid heart rate continue even after opioid withdrawal has been treated. In some cases, additional doses of opioid medication do not improve the remaining symptoms because xylazine affects a different receptor system.
Xylazine Withdrawal is Less Predictable
Healthcare providers have well-established tools for evaluating and treating opioid withdrawal, including the Clinical Opiate Withdrawal Scale. Xylazine withdrawal does not yet have a standardized assessment tool or a single approved treatment protocol.
This uncertainty can make it harder to determine whether symptoms come from xylazine, fentanyl, another substance, or several forms of withdrawal at once. Alcohol and benzodiazepine withdrawal must also be considered when severe agitation, tremors, sweating, or high blood pressure are present.
Xylazine Withdrawal vs Opioid Withdrawal Symptoms at a Glance
Although the two conditions share several symptoms, certain patterns may help healthcare providers distinguish between them.
| Symptom | Opioid withdrawal | Xylazine withdrawal |
| Anxiety and restlessness | Common | Common and may be severe |
| Muscle aches | Common | Possible, especially with opioid co-use |
| Nausea, vomiting, and diarrhea | Common | May occur but are less clearly defined |
| Runny nose, watery eyes, and yawning | Common | Not considered defining symptoms |
| Opioid cravings | Common | Usually related to accompanying opioid dependence |
| High blood pressure | Possible | May be more prominent or persistent |
| Rapid heart rate | Possible | May be more prominent |
| Agitation and irritability | Possible | Frequently reported |
| Response to buprenorphine or methadone | Often improves | Does not directly treat xylazine symptoms |
| Standardized treatment approach | Yes | No established universal protocol |
These differences are not always easy to identify outside a medical setting. When fentanyl and xylazine have been used together, symptoms often blend into one complicated withdrawal experience rather than appearing as two clearly separate conditions.
Can Xylazine Withdrawal be Treated?
Yes, xylazine withdrawal can be treated, but treatment is different from opioid withdrawal because xylazine does not act on opioid receptors. While healthcare providers can manage symptoms and support recovery, there is currently no FDA-approved medication specifically for xylazine withdrawal.
Treatment depends on the person’s symptoms, the substances involved, and whether opioid withdrawal is occurring at the same time.
Supportive Medical Care is Often the Foundation of Treatment
Because xylazine withdrawal can affect blood pressure, heart rate, and the nervous system, healthcare providers may recommend medical monitoring, especially for people with severe symptoms or those withdrawing from multiple substances.
Treatment may include:
- Monitoring blood pressure, heart rate, and hydration
- Managing nausea, insomnia, anxiety, and agitation
- Treating wounds or skin infections when present
- Evaluating for withdrawal from alcohol, benzodiazepines, or other substances if appropriate
Medical supervision also helps providers recognize complications early and adjust treatment as symptoms change.
Medications May Help Manage Specific Symptoms
Although no medication directly reverses xylazine withdrawal, healthcare providers may prescribe medications to reduce individual symptoms.
According to the Penn Center for Addiction Medicine and Policy, medications such as clonidine may help reduce autonomic symptoms like elevated blood pressure, rapid heart rate, sweating, and restlessness because they affect the same alpha-2 adrenergic pathway targeted by xylazine. In some situations, additional medications may be considered based on the patient’s clinical condition and other substances involved.
Treatment is individualized rather than standardized, which is one reason xylazine withdrawal can be more challenging to manage than opioid withdrawal alone.
Suboxone Still Plays an Important Role When Opioids are Involved
Suboxone does not directly treat xylazine withdrawal, but it remains an important treatment for opioid use disorder and opioid withdrawal.
When fentanyl or another opioid is involved, healthcare providers may still prescribe buprenorphine to reduce opioid withdrawal symptoms and cravings while treating xylazine-related symptoms separately. This combined approach addresses both substances rather than relying on a single medication.

When Should You Seek Medical Care?
Withdrawal from fentanyl contaminated with xylazine can be unpredictable. Although opioid withdrawal is rarely life-threatening on its own, xylazine may contribute to significant changes in blood pressure, heart rate, and overall clinical stability.
You should seek medical care promptly if you or someone else experiences:
- Severe agitation or confusion
- Chest pain or difficulty breathing
- Persistent vomiting or inability to stay hydrated
- Extremely high blood pressure or rapid heart rate
- Loss of consciousness
- Signs of an infected or worsening skin wound
Medical evaluation is also important if symptoms continue despite treatment for opioid withdrawal. Persistent anxiety, agitation, elevated blood pressure, or restlessness may suggest that xylazine withdrawal is contributing to the overall clinical picture.

Frequently Asked Questions
What is the difference between xylazine withdrawal and opioid withdrawal?
Opioid withdrawal occurs because opioid receptors are no longer being stimulated, while xylazine withdrawal results from rebound activity in the alpha-2 adrenergic system. Although some symptoms overlap, the two conditions affect different parts of the nervous system and may require different treatment approaches.
Can xylazine and opioid withdrawal happen at the same time?
Yes. Because xylazine is commonly mixed with fentanyl and other illicit opioids, many people experience withdrawal from both substances simultaneously, making symptoms more difficult to distinguish.
Does Suboxone treat xylazine withdrawal?
No. Suboxone treats opioid withdrawal and opioid use disorder, but it does not directly treat xylazine withdrawal. However, it remains an important part of treatment when opioid dependence is also present.
How can healthcare providers tell the difference?
Healthcare providers consider the person’s history, symptoms, vital signs, and response to treatment. Persistent autonomic symptoms, such as elevated blood pressure or rapid heart rate despite appropriate opioid treatment, may suggest xylazine withdrawal is also occurring.
How long does xylazine withdrawal last?
The exact duration is still being studied. Symptoms often begin within hours after the last use, but the course can vary depending on the amount of xylazine used, whether opioids are also involved, and individual health factors.
Can I detox from xylazine at home?
Because xylazine withdrawal is unpredictable and often occurs alongside opioid withdrawal, self-detox may not be safe for everyone. A healthcare provider can determine the appropriate level of care based on your symptoms, medical history, and the substances involved. If you’re considering stopping use, our guide to xylazine detox explains what medically supervised treatment may involve.
