Medication-Assisted Treatment (MAT):

Medicated-assisted treatment (MAT) is the use of FDA-approved medications, in combination with counseling and behavioral therapies, to provide a "whole-patient" approach to the treatment of substance use disorders. There are some major changes occurring with the waiver process with this medication. We will update you all as we get more information.

Medication Information

Methadone, buprenorphine, and Naltrexone are all FDA approved medications for medication-assisted treatment (MAT) for opioid use disorder. Learn more about these medications below.


  1. Methadone

  • Reduces opioid cravings and withdrawal symptoms. You can only receive Methadone while being supervised by a doctor in a clinic setting.

  1. Naltrexone

  • A non-addictive medication that blocks other opioids from attaching to opioid receptors in the brain. This means it blocks the effects of other opioids. Naltrexone can be taken as a pill or as a monthly injection.

  1. Buprenorphine aka Suboxone

  • Reduces opioid cravings and withdrawal symptoms. You can receive Buprenorphine as a daily tablet, cheek film, or implant.

Benefits of MAT

The goal of MAT is to treat the 'whole-patient', so the patient can go on to live an independent life. Some benefits of MAT include:

  • Increases participation in SUD treatment

  • Improves individuals' treatment outcomes

  • Decreased opioid use

  • Reduces needle-sharing and risk of HIV and Hepatitis C contraction

You can find more information about MAT on the SAMHSA website
