Opioids are potent respiratory depressants, and overdose is a leading cause of death among people who use them. Worldwide, an estimated 69 000 people die from opioid overdose each year. The number of opioid overdoses has risen in recent years, in part due to the increased use of opioids in the management of chronic pain. In 2010, an estimated 16 651 people died from an overdose of prescription opioids in the United States of America alone.

Opioid overdose is treatable with naloxone, an opioid antagonist which rapidly reverses the effects of opioids. Death does not usually occur immediately, and in the majority of cases, overdoses are witnessed by a family member, peer or someone whose work brings them into contact with people who use opioids. Increased access to naloxone for people likely to witness an overdose could significantly reduce the high numbers of opioid overdose deaths. In recent years, a number of programmes around the world have shown that it is feasible to provide naloxone to people likely to witness an opioid overdose, in combination with training on the use of naloxone and the resuscitation of people experiencing opioid overdose, prompting calls for the widespread adoption of this approach. In 2012, the United Nations Economic and Social Council (ECOSOC) called upon the World Health Organization (WHO), in collaboration with the United Nations Office on Drugs and Crime (UNODC) to provide advice and guidance, based on scientific evidence, on preventing mortality from drug overdose, in particular opioid overdose.

While community management of opioid overdose with naloxone is expected to reduce the proportion of witnessed opioid overdoses which result in death, it does not address the underlying causes of opioid overdose. To further reduce the number of deaths due to opioid overdose other measures should be considered, such as:

• monitoring opioid prescribing practices;
• curbing innapropriate opioid prescribing;
• curbing inappropriate over-the-counter sales of opioids;
• increasing the rate of treatment of opioid dependence, including for those dependent on prescription opioids.
