Patient Challenges in Utilization of Methadone to Treat Opioid Use Disorder and Perspectives on a Solution for Improved Security and Convenience in Take-home Dosing.

Participants endured a monetary and time burden to access their methadone treatment, and wished to have more take-home doses to reduce the frequency of their visits to the OTP clinic. Participants viewed take-home doses as having a positive impact on their ability to care for family members, hold a job, and travel, and they appreciated the key attributes of COPA and were willing to invest their own funds to gain access to the device. COPA is a potential solution to expand take-home methadone access to patients while ensuring safety, adherence, retention, and appropriate use.
