A 39 year old woman started injecting heroin when she was 18 but soon found she could not control her drug intake or her life in general. At age 30, she sought help and did well with methadone treatment, taking no illicit drugs for three years. However, she then relapsed to heroin use and spent a year in prison, where she continued to inject heroin. After being released, she went to a residential rehabilitation centre. Subsequently in the community her general practitioner started her on buprenorphine. Her life became more stable. She did well with buprenorphine treatment for a few years but restarted injecting heroin after stopping buprenorphine. She restarted buprenorphine and now takes no non-prescribed medication. She works as a waitress and lives with her non-drug using partner.

Treatment with maintenance goals is referred to as opioid substitution treatment or opioid agonist pharmacotherapy.3 Such treatment is reserved for patients with clearly established opioid dependence and prolonged daily opioid use (by either smoking or injecting). In some countries the combination of buprenorphine and naloxone is preferred (and is now becoming available as a film taken sublingually). Prescription heroin, known in the United Kingdom as heroin assisted treatment or injectable opiate treatment, is used in some countries but is not discussed in this article.4 5 6 Naltrexone blocks the effects of heroin on the mu receptor,2 but oral naltrexone treatment has had low adherence and high discontinuity rates.7 8 Use of naltrexone in the …
