Medication-Assisted Treatment (MAT) is an evidence-based approach that combines FDA-approved medications with counseling and behavioral therapies to treat Substance Use Disorder. MAT addresses the physical side of addiction - stabilizing the body so that the deeper work of recovery can begin.
At Northwest Integrated Health (NWIH), MAT medications include Methadone, Buprenorphine, Naltrexone, and Vivitrol. Not every clinic offers every medication.
Medications alone do not cure a chronic disease. MAT is always paired with counseling, regular drug screens, and an individualized treatment plan - because lasting recovery requires healing the body, the mind, and the outlook on life.
The medications
What each medication does, and who it's for.
Your provider will recommend the medication that best fits your history, goals, and clinical picture. You are not locked in - the plan can change as you do.
Methadone
Full opioid agonist · daily liquid dose
A long-acting opioid agonist taken once daily under supervision at the clinic. Methadone occupies the same brain receptors as heroin or fentanyl, which prevents withdrawal and blunts cravings without producing a high at a stable dose.
Who it's for: Often the right fit for people with long-standing opioid use, high tolerance, or prior unsuccessful trials of buprenorphine. At NWIH, methadone is only prescribed when a patient is actively engaged with both a mental health provider and a chemical dependency counselor.
Available at: Lakewood and Tacoma South.
Buprenorphine (Suboxone, Subutex, Sublocade)
Partial opioid agonist · daily film/tablet or monthly injection
A partial agonist that relieves withdrawal and cravings with a built-in ceiling effect, which lowers overdose risk compared with full agonists. Available as a daily sublingual film or tablet, or as Sublocade - a once-monthly extended-release injection.
Who it's for: A flexible first-line option for most patients with opioid use disorder. Can usually be started same-day after a short period of withdrawal.
Available at: All four clinics - Lakewood, Tacoma South, Puyallup, and Tacoma Westgate.
Naltrexone (oral)
Opioid antagonist · daily tablet
A pure opioid blocker - it occupies opioid receptors so that other opioids cannot produce a high. Naltrexone is not an opioid and is not habit-forming. It also reduces alcohol cravings and is approved for alcohol use disorder.
Who it's for: Best for patients who are already fully detoxed from opioids (typically 7–10 days opioid-free) and want a non-opioid medication, or for people treating alcohol use disorder.
Available at: All four clinics.
Vivitrol (extended-release naltrexone)
Opioid antagonist · monthly injection
The same medication as oral naltrexone delivered as a once-monthly intramuscular injection. One shot provides ~28 days of receptor blockade, removing the need to remember a daily pill.
Who it's for: A good fit for patients who are fully detoxed and prefer a monthly visit over daily dosing, including people returning to work, school, or structured environments.
Available at: Lakewood and Tacoma South.
