The connection between relapse and overdose

Getting into recovery was a big step. Staying on track with your recovery can be one of the most rewarding things, but that’s not saying that some days feel harder than others. You’ve been putting in the effort, showing up for yourself, and navigating a process that asks a lot of you. 

Recovery isn’t always a straight line. Some people relapse. However, for those in a Medication-Assisted Treatment (MAT) program, taking medication regularly as prescribed can help prevent relapse and potential overdose. 

Studies show that the period after stopping MAT carries real risks. A study in The BMJ found that fatal overdoses were over 2.1 times higher among people who stopped buprenorphine compared to those who stayed in treatment. Also, Columbia University researchers found that about 1 in 20 people who ended buprenorphine treatment experienced a treated overdose within six months.

So, why does this happen? During recovery, your body’s tolerance to opioids drops. Sometimes, that tolerance drops quite quickly. That same dose that once felt manageable could now be dangerous. As QuickMD Chief Medical Officer Dr. Robert Stern explains: “The first four to six weeks after stopping buprenorphine is one of the most dangerous times for dying of overdose from opioids.”

These statistics aren’t meant to scare you. Rather, they’re there to give you knowledge you can use and a deeper understanding of the full picture so you can protect the progress you’ve made. The good news is that you’re never alone on your journey and your medication is there to reduce cravings, stabilize recovery, and help prevent relapse from turning into a health crisis. Let’s explore what’s happening in your body and why keeping up with your treatment can make a real difference.

Why does relapse increase the risk of overdose?

Relapse is often talked about in emotional terms. While it certainly brings up a lot of feelings, it’s just as important to understand the physical aspects of what’s happening in your body during a relapse. Whether it’s months or years into your recovery, your brain and body are actually rewiring themselves. That changes how they respond to opioids. Here’s a closer look at the key factors at play. 

1. Reduced tolerance

Think of tolerance as your body’s way of adapting to a substance. During active use, your brain adjusts to the presence of opioids, requiring higher and higher doses to get the same effect. But when you stop, your body begins to reset. Tolerance can start dropping in as little as a few days, and within a few weeks of quitting, it can decrease significantly.

Your brain doesn’t send you a notification when your tolerance has dropped. So if someone returns to the same amount they used before, their body may simply not be able to handle it. The dose that felt familiar can suddenly be enough to slow or stop breathing, which is exactly what happens in an overdose. This is why many overdoses happen not to new users, but to people returning to use after a period away.

2. Contaminated drug supply

The opioid supply today is unpredictable in ways it simply wasn’t a decade ago. Many substances sold as heroin or pressed into pills are laced with fentanyl, a synthetic opioid that’s up to 50 times more potent than heroin. Even tiny, barely measurable variations in a batch can turn a standard dose into a fatal one. 

Now combine that with reduced tolerance. A person who relapses after time away may use what they think is a familiar amount, not realizing their body can’t handle it the way it once did, plus the substance itself may be much stronger than expected. It’s this combination of a lower tolerance and an unpredictable drug supply that makes relapse particularly dangerous during a relapse. 

3. Using alone

It’s completely understandable that many people who relapse do so in private. Feelings of shame, guilt, or a sense of having “failed” can make reaching out feel impossible. But using alone significantly raises the risk of a fatal overdose because there’s no one there to call for help or administer Narcan (naloxone). 

If you’re feeling like you’re teetering on the edge of a relapse, you’re not alone. Even if you’ve had a slip up, your QuickMD care team is here for you with zero judgment, just support. A quick message or call can make all the difference. You don’t have to navigate this by yourself. Reaching out isn’t a sign of weakness. It’s one of the strongest things you can do.

What makes a person at higher risk for relapse?  

Relapse isn’t a matter of willpower. Rather, it’s the result of how the brain and body respond to stress, isolation, and biological changes. Understanding what can make a person more vulnerable to relapse can help you recognize risk factors before a crisis occurs.

• Isolation and shame: Unhelpful stigmas around opioid use disorder (OUD) still exist despite research showing that it’s a medical condition and not a moral failing. Isolation and shame aren’t just emotionally painful. They actually change how the brain functions. Social connection is a protective factor in recovery, and when someone pulls away out of shame, they lose one of their strongest safeguards. The shame itself becomes a feedback loop with the worse someone feels about a slip, the less likely they are to reach out, and the more vulnerable they become.
• Men and women have different triggers: Triggers can look different depending on your experience. Men in recovery may face stronger cravings in response to being around people, places, or situations linked to former use. On the flipside, women may experience more stress-related triggers tied to trauma or co-occurring mental health conditions. Both are real, both are rooted in how the brain processes reward and stress, and neither is a character flaw.

What makes relapse most dangerous is when these psychological vulnerabilities meet a lowered physical tolerance. A person who’s been feeling isolated, dealing with emotional stress, and hasn’t been on medication may find themselves in a situation where one decision puts them at serious physical risk. 

However, ongoing care, medication, and building connections with others work with your brain’s wiring rather than against it. Staying engaged with your treatment team and building supportive relationships are relapse prevention strategies grounded in real neuroscience.

How Suboxone® helps break the relapse-overdose cycle 

If a relapse happens, it doesn’t erase the progress you’ve made. You can always begin again. What matters is having the right tools in place to reduce the risks and keep moving forward.

If you’re already taking Suboxone as part of your MAT plan, you’re probably familiar with the basics. It helps with cravings, it keeps withdrawal at bay. But understanding how it works on a deeper level can make a big difference in how you think about your own recovery. Knowing the “why” behind the medication can reinforce why you’re taking it and help you recognize the protection it’s providing, even on days when it feels routine.

1. Reduces cravings

If you’ve been on Suboxone for a while, you may have noticed that the intensity of cravings start to fade. That’s the medication doing its job. Suboxone binds to the same opioid receptors in your brain that once drove those cravings, but instead of producing feelings of euphoria, it stabilizes them. Think of it like turning down the volume on a loud radio. The signal is still there, but it’s no longer overwhelming. This gives you the mental and emotional space to keep building on the progress you’ve made during recovery. 

2. Prevents withdrawal symptoms

If you’ve ever missed a dose, you know exactly what this feels like. Withdrawal symptoms like nausea, anxiety, muscle aches, and restlessness are your brain’s way of reacting to the absence of something it’s adjusted to. Suboxone prevents those symptoms by providing a steady, controlled signal to your opioid receptors. This stability is what allows you to go about your day, show up for work or family, and build a life in recovery without constantly fighting against your own body. 

3. Lowers overdose risk

This is one of the most important things to understand about the medication you’re taking and it’s something that sets Suboxone apart from full opioids.

As a partial opioid agonist, Suboxone activates your opioid receptors, but only to a certain point. This is called the “ceiling effect.” With full opioids (like heroin, oxycodone, or fentanyl), the more you take, the more your breathing slows down.  That slowing of breathing is called respiratory depression, and it’s what actually causes death in an overdose.

Suboxone’s ceiling effect means that beyond a certain dose, it stops having stronger effects. This includes its effects on your breathing. So,  even if someone were to take more Suboxone than prescribed, it’s extremely unlikely to cause respiratory depression the way a full opioid would. This built-in safety mechanism is one reason Suboxone is considered such an effective tool for long-term recovery.

Because Suboxone works on your opioid receptors and doesn’t produce euphoria, it can actually blunt the effects of other opioids if a relapse were to occur. It’s not a force field, but it does offer added protection.

The research backs this up in a big way. Studies have shown that people in MAT had an 80% lower risk of dying from an opioid overdose compared to those in non-medication treatment. Additionally, there was a 62% reduction in fatal overdoses among people who received buprenorphine after a nonfatal overdose. 

Research shows that staying on Suboxone long term consistently provides the best protection. Staying engaged with your treatment, even when things feel stable, is one of the most protective choices you can make.

4. Encourages routine and accountability

If you’re already on Suboxone, you know it becomes part of your rhythm. It’s a daily touchpoint that keeps you connected to your recovery. That structure matters more than you might think. Taking your medication as prescribed creates a small but meaningful anchor in your day. Similarly, having regular check-ins with your QuickMD doctor give you an opportunity to talk about how things are going, make adjustments if something isn’t working, and feel seen by someone who understands what recovery is all about. Over time, this routine becomes part of a larger practice of showing up for yourself.
