Xylazine-associated wounds can occur away from an injection site because the tissue injury appears to involve more than local needle trauma. Clinical reports describe characteristic wounds at distant body sites and even in people who report smoking or snorting xylazine-containing fentanyl rather than injecting it.
What do xylazine-associated wounds look like?
Reports describe blisters or reddish-purple areas that can progress to dark eschar and deep ulcers. Some wounds contain islands of intact skin and may eventually expose tendon or bone.
Why can wounds develop away from injection sites?
The exact mechanism is not yet fully established. Researchers have proposed that xylazine’s effects on blood vessels, tissue perfusion, inflammation, repeated sedation, and other factors may contribute to tissue injury. The fact that wounds occur at noninjection sites suggests systemic exposure can play a role.
Can people who smoke or snort xylazine-contaminated drugs develop wounds?
Yes. CDC reports and clinical wound-care literature describe xylazine-associated wounds in people who did not inject the drug. That finding is one reason clinicians should not dismiss xylazine-related injury simply because there is no injection at the wound location.
Why can these wounds become serious?
They can deepen, become infected, involve bone or tendon, and in severe cases contribute to osteomyelitis, sepsis, amputation, or other major complications. Early wound care is important.
Should every wound in a person using fentanyl be assumed to be caused by xylazine?
No. Skin wounds have many possible causes. Clinicians need to consider infection, vascular disease, injection injury, burns, pressure injury, and other conditions. Xylazine exposure is one important possibility when the drug supply or wound pattern raises concern.
When should someone seek medical care?
Medical evaluation is especially important for spreading redness, fever, severe pain, foul drainage, exposed tissue, rapidly enlarging wounds, numbness, or signs of systemic illness.

Frequently asked questions
Do xylazine wounds only happen to people who inject?
No. They have also been reported at noninjection sites and in people who smoke or snort xylazine-containing drugs.
Can xylazine wounds become infected?
Yes. Secondary infection, cellulitis, abscess, and osteomyelitis have been reported.
Does naloxone treat xylazine wounds?
No. Naloxone is an opioid-overdose reversal medication and does not treat tissue injury.
Can these wounds heal?
Some improve with cessation of exposure and appropriate wound care, but severe wounds can require prolonged multidisciplinary treatment.
