Outpatient non-opioid detoxification for opioid withdrawal. Who is likely to benefit?

The authors examined characteristics of successful completers of an outpatient clonidine/oxazepam detoxification procedure for opioid dependence. Of 215 initial applicants, 167 received medication, and 65 successfully completed by taking a dose of naltrexone. Those who completed were more likely to have last used an opioid other than heroin, to be heroin smokers, rather than intravenous users, to have used benzodiazepines in the 30 days before treatment, and to have abstained from opioids for a longer time before presenting for treatment. New users (for less than 2 years) did no better than those using longer than 2 years. These findings may help in the continued refinement of patient placement criteria.
