Benzodiazepine Discontinuation in Opioid Agonist Therapy

Distress Tolerance - Benzodiazepine Discontinuation (DT-BD) is a psychosocial intervention. It is paired with a benzodiazepine taper. The aim of the psychosocial intervention is to improve individuals' ability to tolerate distress in order to assist benzodiazepine discontinuation in patients treated with OAT. There will be 5 sessions between therapist and participant prior to the start of the benzodiazepine taper. The taper for both the intervention and control conditions occurs over 9 weeks and involves weekly meetings with a benzodiazepine prescriber during which a gradual benzodiazepine dose reduction will take place. The DT-BD intervention combines elements of existing psychosocial interventions. Specifically, interoceptive exposure techniques will be paired with elements of acceptance and commitment therapy (ACT) and relapse prevention (RP).

All participants will undergo BZD discontinuation. Once the starting BZD dose is determined by prescription monitoring and/or self-report, we will maintain participants on this dose until the start of the BZD taper. Participants will see a study physician weekly to receive their BZD medication for the week until the taper is completed. BZD discontinuation in this study will consist of a gradual BZD taper in dose over 9 weeks. The taper will be flexible in that the study physician will utilize clinical judgement to lengthen the taper if necessary, depending on the severity of the participant's withdrawal symptoms. Anchor points will be set (33% reduction in dose after 2 weeks, 50% mid-treatment, 100% by week 8) to emphasize the time-limited nature of the taper.
