Understanding opioid harm reduction

close shot of many hands together

Not all people who use alcohol or other drugs want to stop or reduce their use.

And, some people who do want to stop, may not be ready to take that step yet.

Because we know all drug use carries a risk of harm, we want to try and reduce some of that risk1 and this can be achieved through harm reduction.

Harm reduction covers specific policies, programs and practices that can reduce the harms associated with substance use – whether that’s harms related to physical or mental health, individuals, families or the broader community.2, 3

Harm reduction can be applied to any substance, by any person, in any environment.4

Here we discuss harm reduction in relation to opioid use.

Opioid use on the rise

We’re seeing a concerning rise in opioid use in Australia.5

Opioids include certain types of painkillers, such as codeine or oxycodone, as well as illegal drugs like heroin.

All opioids can cause dependence and can result in accidental overdose, hospitalisation or death.6

Vital organs such as the lungs, brain and heart can also be damaged by opioids.7

Every day in Australia, there are approximately 150 hospitalisations and 14 emergency department presentations involving opioids.

And three people die from drug-induced deaths involving opioids each day.5

For people experiencing opioid addiction (dependence), there are specific harm reduction approaches that can help reduce some of these risks.

Harm reduction at home

If you – or someone you know – uses opioids, try taking the following harm reduction measures:

  • encourage family and friends to learn how to use take home naloxone – a medicine that can reverse the effects of an opioid overdose (more information on naloxone is provided below)
  • avoid mixing drugs (polydrug use) – mixing opioids with depressant drugs such as alcohol or benzodiazepines can greatly increase the risk of overdose
  • don’t use opioids alone and always tell someone what you’ve taken
  • if using illicit opioids such as heroin, test with a small amount to reduce overdose risk
  • do not drive or operate machinery after use
  • always use clean needles and never share injecting equipment
  • safely dispose of used injecting equipment.

If you know someone who has had a bad reaction after taking opioids, never leave the person to ‘sleep it off’. Snoring or gurgling could mean someone is having trouble breathing and may be experiencing an overdose.8 Call 000 immediately.

Harm reduction in the community

There are many harm reduction programs and services for people who use opioids (and other drugs).

Needle and syringe programs (NSPs) provide sterile needles and syringes to people who inject drugs to stop the spread of blood borne viruses such as HIV/AIDs and hepatitis B and C.

They also provide other paraphernalia (such as tourniquets) for free, or at a low cost. Australia has one of the lowest rates of HIV transmission via injecting drug use because of the availability of NSPs.9

Needle and syringe programs can be found across metropolitan and regional Australia.

NSPs provide a range of services, including:

  • information and education
  • safe disposal containers
  • sterile injecting equipment
  • referrals to treatment services.9

Pharmacotherapy is the use of prescribed medication to help treat alcohol or drug dependence.

Pharmacotherapies for opioid dependence include buprenorphine and methadone. Buprenorphine is now available as a long-acting formulation that can be taken weekly or monthly.

People living with a dependence on heroin or prescribed opioids often struggle to stop or reduce their use because of unpleasant withdrawal symptoms or cravings.10

Methadone and buprenorphine can prevent withdrawal and cravings for opioids10, reducing the risks associated with continued use such as overdose, infection, poor health and even death.

These medications can also help people who want to come off opioids completely.

More information

Naloxone is a medication that rapidly reverses an opioid overdose.

If a person's breathing has slowed or stopped because of an opioid overdose, naloxone can quickly restore regular breathing. It is available as an injection or nasal spray.11

Naloxone can be administered by anybody and can be prescribed by a doctor in all states and territories.

You can also get it from any community or hospital-based pharmacy, however there are different conditions in different states – it’s free in NSW, SA and WA under the take home naloxone program8 and available for a small fee everywhere else.

Naloxone is also freely available at needle and syringe programs across VIC, NSW, SA, TAS and WA.

More information

Supervised injecting facilities (SIFs) are a hygienic place where people can inject drugs.

These are supervised by health workers, so if someone overdoses a staff member can respond straight away.

SIFs can:

  • reduce overdose deaths and harm
  • reduce ambulance attendances and emergency department presentations
  • reduce the number of discarded needle and syringes in public places
  • reduce the risk of blood borne viruses such as HIV and hepatitis C
  • provide referrals to treatment and support
  • provide access to other health and social services for people who inject drugs.12-18

Key harm reduction services in Australia

In Australia we have harm reduction services in every state and territory.

If a loved one is experiencing social or physical harm from drug use, these services can provide support and advice:

Remember, taking care of yourself is just as important as helping others.

If you are affected by someone’s alcohol or drug use, you can contact the following 24-hour helplines for information and support.

Family Drug Help (VIC, SA and TAS): 1300 660 068

Family Drug Support (NSW, QLD, NT and ACT): 1300 368 186
