[Take-home naloxone: a building block of drug emergency prophylaxis in Germany]

Naloxone is an opioid antagonist that reverses the (respiratory-paralyzing) effects of opioids in the body within minutes. Naloxone can therefore reduce opioid overdose deaths. Take-home naloxone (THN) is an intervention recommended by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and the World Health Organization (WHO). It involves training opioid users and their relatives or friends in the use of naloxone and providing them with the drug in case of emergency.So far, THN has been implemented in Germany mainly by individual addiction support facilities. In order to fully exploit the potential of THN, it is necessary to establish the measure nationwide. In particular, THN can be included in the services offered in (low-threshold) addiction support facilities, in psychiatric facilities, in the context of opioid substitution treatment, and in the correctional system.This discussion article reviews the development of THN in Germany since 1998, highlights the difficulties and obstacles to its widespread implementation, and outlines how THN can succeed as an effective public health intervention in Germany. This is particularly relevant in view of the increasing number of drug-related deaths over the past 10 years.
