The Harris County Sheriff's Office (HCSO) Vivitrol Pilot Program will provide a long acting non-narcotic, non-addictive medication (Vivitrol: Naltgrexone for extended release injectable suspension, 30 mg/vial) combined with comprehensive substance abuse counseling and case management services to eligible offenders upon release from the Harris County Jail. Administration of this drug prior to institutional release will allow newly-released participants to focus on immediate re-entry needs without having to struggle with drug cravings as Vivitrol is designed to reduce cravings for alcohol and/or opiates, also blocking the ability to get high or feel euphoria.


Program Objectives

  • Support the implementation of evidence-based programs and promising practices addressing substance use and behavioral health in the Harris County Jail
  • Support the implementation of a Medication Assisted Treatment (MAT) program in conjunction with behavioral health treatment in the Harris County Jail
  • Strengthen the inmate's cognitive, behavioral, social, and vocational skills


Program Goals

  • To assist inmates from relapsing into opiod and/or alcohol dependence
  • Decrease risk factors for substance use disorders and promote a healthy lifestyle without substance use
  • Lower reoffending and/or recidivism rates
