Are You or Someone You Know Struggling with Addiction to Alcohol, Heroin, Oxycodone, Hydrocodone, or other Opioids?


Did you know research shows that 90% of individuals with Opioid Use Disorder (OUD) that participated in Medication Assisted Treatment (MAT) were not dependent on the drug of choice at the 3.5 year follow-up?

At Journey Road, we offer Medication Assisted Treatment (MAT), such as suboxone and vivitrol for individuals struggling with addiction to alcohol and opioids as an evidence-based approach to treatment.

We recently opened a Medication Assisted Treatment clinic on the westside of Indianapolis!
