The tablets are green, round, marked 'OC' on the front and '80' on the reverse, and lack film coating.

Legitimate Oxycontin is now marked 'ON' instead of 'OC' and has a film coating.

Tablet appearance is not a reliable indicator of drug contents.

Know the risks

• Nitazenes, such as N-desethyl isotonitazene, are synthetic opioids that are stronger and may be longer acting than many other opioids. They are up to 500 times more potent than heroin.
• Fake oxycodone or 'OxyContin' tablets may contain nitazenes or other unexpected drugs. They may have incorrect or no markings, be poorly made, powdery, or lack film coating.
• Nitazenes are dangerous and vary in strength - some nitazenes are so potent that there is no safe dose. The purity can also vary within a single batch.
• Nitazene use has been linked to death and other serious harms in NSW.
• The risks of overdose are increased if you:
• Use drugs alone.
• Use nitazenes or other opioids if you have not used them before.
• Use drugs again after a break.
• Use with other drugs (like alcohol, benzodiazepines, ketamine or GHB).
• Use a new batch.
• Naloxone can temporarily reverse an overdose from opioids. Nitazenes may require repeated doses of naloxone. Always ring an ambulance. The effects of naloxone may wear off, and ongoing doses and hospital treatment may be needed.
• Fentanyl test strips do not detect nitazenes.

Effects to look out for

• Pin-point pupils, drowsiness, loss of consciousness, slow breathing/snoring or skin turning blue/grey.
• If you or others experience these symptoms, get help immediately.

Getting help

• If you or your friends see the warning signs of overdose:
• Seek help immediately from your nearest emergency department or call Triple Zero (000). You won’t get into trouble for seeking medical care.
• Start CPR if someone is not responsive.
• Use naloxone if you have it. Call '000' even if naloxone has been given.

Take Home Naloxone program

• Naloxone is a life-saving medicine that can temporarily reverse an opioid overdose. Naloxone is available in an easy to use nasal spray, and as a pre-filled injection.

• You should carry naloxone if:
• You are using drugs such as cocaine, ketamine, methamphetamine, MDMA, or opioids.
• You are hosting or going to a party where drugs will be present.
• If you might experience or witness an opioid overdose you can get naloxone for free without a prescription in NSW from many community pharmacies, needle and syringe programs, opioid treatment services and NUAA.
• Visit Your Room for participating sites and more information on take home naloxone.
• NUAA can mail you naloxone in a discreet package. Order via their online shop​ or call (02) 9171 6650.
