Primary outcomePrimary: Successful Vivitrol Induction — 10 Participants
Summary
This is an open-label pilot trial to evaluate the safety and tolerability of lofexidine in the management of opioid withdrawal symptoms while initiating outpatient treatment with naltrexone. The initiation procedure will be a flexible detoxification lasting 2 to 10 days concluding with the injection of XR-Naltrexone (Vivitrol). Vivitrol is a long-acting injection that contains enough medicine to last for one month blocking the effects of opioids.
