What to Expect From MAT During Detox and Beyond

What Does MAT During Detox Actually Involve?

Picture the first 72 hours after someone stops using heroin or fentanyl. Sweats, chills, a racing heart, stomach cramps, and a restlessness that makes sleep nearly impossible. For a lot of people, that stretch is exactly when they give up and use again.

Medication assisted treatment (MAT) steps into that window. A medical team uses FDA-approved medications to steady the body while it adjusts, then pairs them with therapy and support. In a MAT integrated detox, medications aren’t an add-on handed out at discharge. They’re part of the plan from day one, adjusted by doctors and nurses who check in around the clock.

MAT for substance abuse isn’t limited to opioids, either. Alcohol detox often uses medication to prevent seizures, and drugs like naltrexone and acamprosate can help afterward. But opioids are where the evidence is strongest, so that’s the focus here.

Which Medications Are Used in a MAT Program?

Three medications for opioid use disorder have the strongest research behind them:

• Buprenorphine (often combined with naloxone as Suboxone) partially activates opioid receptors. It eases withdrawal without the same high, and its “ceiling effect” makes it harder to overdose on when taken alone.
• Methadone is a long-acting, full opioid agonist. It’s dispensed through certified opioid treatment programs and often suits people with heavy, long-term opioid dependence.
• Naltrexone has an opioid antagonistic effect, meaning it blocks opioids from working at all. Because of that, it can only begin once someone has been opioid-free for about 7 to 10 days.

Many detox programs also include medication that isn’t an opioid, like lofexidine or clonidine, to calm the body’s fight-or-flight response. Doctors may add short-term help for nausea, diarrhea, or sleep.

The right choice depends on what someone was using, how much, their health history, and what they want long-term. Good treatment plans start with that conversation, not a default prescription.

How Does MAT Help With Withdrawal Symptoms and Cravings?

Opioids change what the brain’s receptors expect. Cut off the supply suddenly, and the nervous system overreacts. That’s withdrawal.

Buprenorphine and methadone occupy those same receptors in a steady, controlled way. Reducing withdrawal symptoms like this means people can eat, sleep, and actually take part in treatment. Managing withdrawal symptoms well also means fewer people walk out of detox early.

Then there’s reducing cravings, which may be the bigger deal. Physical withdrawal from short-acting opioids often peaks within a few days, but cravings can hang around for months. When withdrawal symptoms and cravings are both under control, the brain finally has room to focus on something besides the next dose.

Timing matters, though. Start buprenorphine too soon, and it can trigger sudden, intense withdrawal. With fentanyl, which lingers in the body longer, clinicians often wait or use special low-dose starting methods. That’s one reason detox through medication-assisted treatment belongs in a supervised setting.

Isn't MAT Just Swapping One Drug for Another?

You’ll hear this a lot, sometimes from family, sometimes from people in recovery groups.

Here’s the difference. Addiction means compulsive use, loss of control, and continuing despite harm. Someone taking buprenorphine as prescribed isn’t chasing a high, buying from dealers, or gambling on a fentanyl-laced pill. They’re taking a measured dose of medicine, much like someone with diabetes takes insulin.

The research backs this up. Methadone and buprenorphine substantially lower overdose deaths and help people stay in treatment longer. That’s why major medical groups see medically assisted treatment as the gold standard to treat opioid use disorders.

Some people taper off after a few months. Others stay on medication for years. Both paths can work.

What Side Effects Should You Expect?

Most of what people notice is mild and fades as the body adjusts.

Common side effects of buprenorphine include constipation, headache, nausea, and sweating. Methadone can cause drowsiness and, in some people, heart rhythm changes, so doctors may order an ECG. Naltrexone can cause nausea and, with the monthly shot, soreness where it’s injected.

One risk gets overlooked far too often: tolerance drops fast during detox. If someone leaves treatment and goes back to illicit opioid use at their old amount, the risk of overdose jumps sharply. Staying on medication after detox is one of the best protections against that.

Where Do Counseling and Behavioral Therapies Fit In?

Medication quiets the body. It doesn’t untangle why someone started using or what sets them off.

That’s where counseling and behavioral therapies come in. Cognitive behavioral therapy helps people catch the thought patterns that lead to use. Dialectical behavior therapy builds skills for handling intense emotions. Family sessions can rebuild trust and help loved ones understand what MAT really is.

In detox, therapy often starts small, maybe a one-on-one check-in or a group session once someone feels steady enough to sit through it. It grows from there. Together, medication and therapy give people the strongest chance to prevent relapse.

What Happens After Detox Ends?

Detox usually lasts about 5 to 10 days. Think of it as a starting line.

From there, people move into other levels of care, like residential treatment, partial hospitalization, intensive outpatient, or standard outpatient. Staying on medication through that shift keeps things stable while daily life fills back in.

A strong MAT program plans the handoff so there’s no gap in prescriptions. Missing even a few days can bring cravings back at the worst possible moment. Ask any facility how they handle this before you commit. Their answer says a lot about whether they treat opioid use disorders (OUD) as the long-term condition they are.

How Does Scottsdale Detox Approach MAT?

At Scottsdale Detox, MAT during detox is part of care from your first assessment. Our medical team looks at what you’ve been using, your health history, and your goals, then builds a plan around you. That could mean buprenorphine, naltrexone after a full detox, or non-opioid medications to take the edge off.

Nurses monitor you around the clock and adjust doses as symptoms change. Counselors start working with you as soon as you’re ready. Before you leave, we line up your next step, whether that’s residential care, outpatient support, or a prescriber closer to home, so your medication continues without a gap.

Tried to quit before, only to have withdrawal pull you back? That isn’t weakness. You were likely missing the right support. We’ll walk you through your treatment options and help you choose what fits.
