Medetomidine: What You Need to Know

Medetomidine is a powerful non-opioid sedative showing up as a cut in New Jersey’s street dope supply. Below is what to watch for and how to respond. Check out the bottom of the page for a printable PDF.

What is it?

  • A strong non-opioid animal sedative & tranquilizer similar to xylazine (tranq) but much stronger — as much as 100-200x stronger in some cases
  • A central nervous system (CNS) depressant, stronger than most people are expecting their bag to be
  • Currently emerging as a cut in the street dope supply in New Jersey — including here in New Brunswick, other parts of Middlesex County, and in markets across the state

People who've used dope cut with metetomidine report:

  • Instantly falling asleep or unable to stay awake
  • Long-lasting, heavy sedation, confusion, dizziness
  • Hallucinations and feeling physically stuck but mentally present — described as “sleep paralysis” and “a waking dream”
  • Increase in urination (dehydration risk)
  • Muscle twitches and erratic body movements
  • Shortness of breath or slowed breathing 
  • Significant drops in blood pressure and heart rate

Withdrawal risks:

  • Life threatening increase in heart rate and blood pressure
  • Tremors
  • Nausea
  • Uncontrollable vomiting
  • Excessive sweating
  • Confusing or “not knowing if you’re awake”

Seek hospital care if any of these systems present. 

Overdose Response:

  • If you think someone is overdosing, respond with rescue breaths and naloxone like normal
  • Give rescue breaths before naloxone and try to get them breaking
  • If still not breathing, give one low-dose of naloxone
  • Right after naloxone dose, give rescue breaths for 2-4 minutes or until they are breathing
  • If not breathing after four minutes, give second naloxone done and repeat rescue breathing
  • When the person begins to breathe on their own, you gave enough naloxone!
  • Move them into the recovery position and monitor breathing until they wake up
  • Massage/squeeze their arms and legs (with consent) to prevent muscle atrophy
  • When they’re awake, sit them up slowly and encourage them to take it easy for 30-90 minutes until naloxone wears off and their opioid receptors open back up

Harm Reduction Tips:

  • Get your drugs checked — knowing what you’re using helps you know how to stay safer while using
  • Be mindful of your tolerance and any tolerance changes (e.g. just left jail, hospital, rehab, using less overall)
  • Carry naloxone and be confident in how to use it, including rescue breathing!
  • If you know or think there’s medetomidine in your drugs, try not to use alone — unpredictable heavy sedation can leave you vulnerable if alone
  • If using in a group, take turns and spot each other
  • Share this info with your friends and make a safety plan in case of overdose or unwanted sedation

Harm reduction is essential. A harm reduction approach to drug use is the best strategy we have to end the overdose crisis, reduce risks associated with drug use, and affirm the dignity and bodily autonomy of every New Jerseyan.
