Xylazine and Fentanyl Detox in San Diego: What to Tell Admissions and How Wound Care and Overdose Planning Change

If you or someone you love has been using fentanyl, there is a real chance the supply also contained xylazine, a veterinary sedative often called “tranq.” That changes what an admissions team needs to know before detox starts, what a medical team watches for in the first days, and how a safety plan should be built for after discharge. This guide covers what to tell admissions, how detox adjusts when xylazine may be involved and what to ask a San Diego program before arriving.

If someone is unresponsive or breathing very slowly right now, call 911. Give naloxone if you have it, even if you suspect xylazine, and give rescue breaths if you are able.

What Xylazine Is and Why It Matters for Detox

Xylazine is a sedative approved by the U.S. Food and Drug Administration for use in animals, not people. According to the National Institute on Drug Abuse (NIDA), it is not an opioid, it is most often found mixed into illicit fentanyl, and many people take it without knowing it is there. It slows breathing, heart rate and blood pressure, and repeated use is associated with skin wounds that can become serious if they are not treated.

Xylazine-involved fentanyl is a national problem, and federal data show how widely it has spread. The Centers for Disease Control and Prevention (CDC) reports that the DEA has seized fentanyl-xylazine mixtures in 48 of 50 states, and that DEA laboratories found xylazine in roughly 23% of fentanyl powder and 7% of fentanyl pills seized in 2022. On July 11, 2023, the White House released a national response plan after fentanyl mixed with xylazine was declared an emerging threat. For anyone entering detox for fentanyl use, the practical takeaway is that admissions staff should treat xylazine exposure as possible unless there is a clear reason to rule it out.

What to Tell Admissions Before You Arrive

On the pre-admission call, a detox team decides what level of medical monitoring is needed and whether anything must be handled at a hospital first. You do not need to know for certain whether xylazine was present. Before the call, write down answers to these questions:

• What substances have been used in the past 30 days, how often and by what route (smoking, snorting, injecting, swallowing)?
• Has anyone mentioned “tranq,” or have you noticed heavier, longer-lasting sedation than expected from fentanyl alone?
• Are there any open sores, wounds, abscesses or areas of skin that look darkened or are not healing, including places that were never injection sites?
• Has there been an overdose in the past few months, and was naloxone used? Did the person stay sedated after naloxone was given?
• Are alcohol, benzodiazepines or other sedatives also being used?
• What prescriptions, including any buprenorphine or methadone, are currently being taken?

The wound question matters more than most people expect. Embarrassment often keeps skin wounds unmentioned until a nurse sees them during the physical exam. Mentioning them on the phone lets the medical team plan wound care from day one, or recommend that a severe wound be evaluated at a hospital before residential admission. NIDA notes that these wounds can appear away from injection sites, and some clinicians report them even in people who smoke or snort rather than inject, so do not leave a wound out just because it seems unrelated.

How Intake and Detox Change When Xylazine May Be Involved

When xylazine may be present, a few parts of fentanyl detox get added or watched more closely:

Sedation monitoring: Because xylazine is a central nervous system depressant, staff pay close attention to breathing, heart rate and blood pressure, especially in the first hours after arrival.

Withdrawal intensity: NIDA notes that early research suggests withdrawal symptoms may be more intense for people using xylazine with fentanyl than fentanyl alone, so comfort medications and close follow-up matter.

Wound assessment: A nurse or physician examines the skin, documents any wounds and starts a cleaning and dressing plan; NIDA states that medical associations have not yet issued formal treatment guidelines for these wounds, so care is individualized.

Polysubstance screening: NIDA reports that most overdose deaths involving both xylazine and fentanyl also involved other substances, including benzodiazepines and alcohol, so the team screens for everything, not just opioids.

One detail families are often surprised by: xylazine is not included in many standard urine drug screening panels, so a routine test can show fentanyl and say nothing about xylazine. That is why what you report at intake carries so much weight.

If alcohol or benzodiazepines are part of the picture, withdrawal from those substances can cause seizures and can be life-threatening. Medically supervised detox may be required, and they should never be stopped abruptly without medical guidance. Learn more about how medical monitoring works at our San Diego detox program.

Medication for Opioid Use Disorder Still Applies

Xylazine is not an opioid, but a person in detox for fentanyl use often has an opioid use disorder as well. That means evidence-based options such as buprenorphine, methadone or extended-release naltrexone remain central to treatment planning. Xylazine does not respond to these medications, which is why wound care, sedation monitoring and symptom management run alongside them rather than replacing them. Our medication-assisted treatment program explains how these medications are started and continued after detox.

Ask the medical team directly: “Which medication for opioid use disorder are you recommending, when will it be started, and who will prescribe it after I leave?” Getting that answer before discharge helps prevent a dangerous gap in care.

What the First Days Usually Look Like

The first night in detox is often the hardest. Expect frequent vital-sign checks, including overnight, and regular withdrawal scoring. Restlessness, aches and poor sleep are common, and staff use medications to ease them. If wounds are present, dressing changes are scheduled and the skin is checked daily for signs of infection, such as spreading redness, warmth, swelling or fever.

Within the first few days, conversations shift toward the next step: residential treatment, a partial hospitalization program or an intensive outpatient program, depending on medical stability, home environment and how withdrawal is going. Wounds often take longer to heal than withdrawal takes to settle, and NIDA notes that early data suggest healing is slower if use of xylazine-containing drugs continues. A discharge plan should name who will continue wound care, whether that is a primary care physician, a wound clinic or the next level of treatment.

Overdose Safety Planning After Detox

Tolerance drops during detox, which raises overdose risk if use resumes. With xylazine in the supply, the plan needs a few extra pieces. CDC guidance covers the essentials:

• Give naloxone anyway: Naloxone does not reverse xylazine, but it reverses the opioids that are usually present, and it does not cause harm if opioids are not involved.
• Call 911 every time: Sedation from xylazine can continue after naloxone works on the opioid, so emergency medical care is still needed.
• Give rescue breaths: CDC notes first responders report rescue breaths are especially helpful because xylazine slows breathing.
• Use the recovery position: If the person is breathing, roll them onto their side and stay with them until help arrives.

Here is a step you can take today: make sure naloxone is in the home of anyone in early recovery from fentanyl use, and that at least two family members know where it is kept and how to use it. Naloxone nasal spray is available without a prescription. Then practice saying the three steps out loud: naloxone, 911, rescue breaths.

Questions to Ask Any San Diego Program

When you call a program, these questions help you understand whether it is set up for fentanyl detox where xylazine may be involved:

• How do you assess and treat skin wounds, and when would you send someone to a hospital first?
• Which medications for opioid use disorder do you offer, and how is continuity arranged after discharge?
• Does your discharge plan include naloxone and overdose education for family members?

To talk through any of these questions with our admissions team, call 619-350-8220. If you are in crisis or thinking about harming yourself, call or text 988 to reach the Suicide and Crisis Lifeline.

Getting Started

You do not have to know exactly what was in the supply to ask for help. Share what you know, mention any wounds and be honest about every substance being used. That information lets a medical team build a safer plan from the first hour. Our admissions staff can verify insurance and explain the intake process. Reach us at 619-350-8220.
