Medication-Assisted Treatment: The Gold Standard for Opioid Recovery

MAT combines FDA-approved medication with counseling to treat opioid use disorder — and it’s the most effective approach available.

Relieves Withdrawal and Treats the Whole Condition

Opioid use disorder changes brain chemistry and causes severe withdrawal symptoms when use stops. Methadone relieves withdrawal immediately, stabilizing cravings so recovery becomes possible. People on MAT are significantly more likely to stay in treatment and less likely to overdose.

Doesn’t Get You High —
Gets You Well

When taken as prescribed under medical supervision, MAT medications don’t produce euphoria. Methadone stabilizes your brain chemistry so you can feel normal, go to work, and focus on recovery.

Works Best Alongside Counseling

At THS, medication is never a stand-alone solution. Every patient receives counseling, medical monitoring, and a recovery plan tailored to their goals — not a one-size-fits-all approach.

Methadone and Suboxone: Two Proven Medications for Opioid Use Disorder

Both methadone and Suboxone are FDA-approved, evidence-based medications for opioid use disorder. After a comprehensive assessment, your THS provider will recommend the right medication for your situation — taking into account your history, current use patterns, and treatment goals.

Methadone

A daily medication dispensed at your THS clinic under medical supervision. Methadone is best suited for severe opioid dependence, particularly for those using heroin or fentanyl heavily. No pharmacy visit required — your THS clinic handles everything.

Suboxone

A prescribed medication for moderate opioid dependence. Whether Suboxone is appropriate depends on your individual situation — your THS provider will determine if it’s the right fit during your assessment.

We’ll help you decide which is best for your situation. Call 1-833-278-HELP or walk in today — no referral needed.

What to Expect at THS

Starting treatment can feel overwhelming. Here’s what the process looks like — step by step.

1

Assessment

Every new patient meets with a counselor to discuss their history, goals, and needs. This shapes an individualized treatment plan — and determines which medication is right for you.

2

Medication

Your physician recommends methadone or Suboxone based on your assessment. For methadone patients, dosing begins under medical supervision at your THS location — with withdrawal relief starting from the first dose.

3

Counseling

Evidence-based counseling runs alongside medication — individual sessions, group support, and case management to build recovery skills and address the underlying challenges of addiction.

4

Ongoing Support

Recovery isn’t linear. If setbacks happen, we adjust your plan — with no judgment. Our goal is long-term recovery and whole-person wellness.

Recovery is Possible

Hear from patients who’ve found a path forward with THS — including Betty, who has been in methadone maintenance for over 40 years.

The relief was just—even on the first day, it was just amazing. Just knowing I didn’t have to do things I didn’t want to do. I could start rebuilding a life. Methadone was a real miracle for me.

Betty

I’m able to get up every day, go to work, and I don’t need help from anybody. I know that without treatment, it would be a downward spiral for me. I consider my counselor a friend because I know I can come to them with anything I’m struggling with and won’t be judged. Treatment is always worth a shot; give sobriety a chance.

Scott

You’re able to come off opiates safely on your own time. I never thought it was possible, but I did it. It’s just so much better living a clean life.

Treatment length is determined by your health and recovery goals — not an arbitrary timeline.
