This is one of the most important safety topics in buprenorphine treatment, so we're going to be direct about it. Suboxone (buprenorphine/naloxone) works well specifically because it's taken consistently, and stopping it abruptly changes things in your body faster than most people expect. None of this is meant to scare you away from ever adjusting your treatment — tapering off medication is a legitimate goal for some patients — but it needs to happen with your provider's guidance, not on your own timeline.
Withdrawal Symptoms After Stopping
Buprenorphine, like other opioids, causes physical dependence when taken regularly. That's a normal, expected part of how the medication works and is not the same thing as addiction. But it does mean your body has adjusted to having buprenorphine on board, and if you stop taking it abruptly, your body needs time to readjust. The FDA's prescribing information for Suboxone notes that physical dependence occurs with buprenorphine use and recommends gradually tapering the dose to avoid the signs and symptoms of withdrawal, rather than stopping all at once. Withdrawal from buprenorphine can be uncomfortable — think flu-like symptoms, trouble sleeping, anxiety, and strong cravings — and for many patients it's the discomfort of withdrawal itself that makes an unplanned stop hard to sustain.
Why Relapse Risk Increases
Withdrawal isn't just physically uncomfortable — it also makes relapse more likely. When your body goes into withdrawal, cravings tend to intensify at the same time your coping resources are stretched thin. The American Society of Addiction Medicine (ASAM), the leading professional society for addiction medicine in the U.S., addresses this directly in its national treatment guideline for opioid use disorder.
ASAM's National Practice Guideline states that abruptly stopping medication for opioid use disorder "may lead to strong cravings, and/or acute withdrawal syndrome which can put the patient at risk for relapse, overdose, and overdose death."
In other words, the same abrupt stop that causes withdrawal is also the thing most likely to push someone back toward opioid use — at exactly the moment their body is least prepared to handle it safely.
Why Overdose Risk Increases After Stopping
This is the part patients are often least prepared for, and it's genuinely important to understand — not to scare you, but because it can save your life. When you take buprenorphine consistently, your body maintains a certain tolerance to opioids. Once you stop, that tolerance drops relatively quickly, often within days to a couple of weeks. If you return to using illicit opioids after that happens, a dose that used to feel "normal" for your body can now be enough to slow or stop your breathing — a fatal overdose.
This risk is even higher today because of how common fentanyl is in the illicit drug supply.
According to the CDC, fentanyl is up to 50 times stronger than heroin and 100 times stronger than morphine. Because it's so potent, even a small dose can be fatal — and illicit drugs are increasingly mixed with fentanyl, often without the user's knowledge.
Put together, lower tolerance plus a riskier drug supply is why an unplanned stop is one of the most dangerous moments in opioid use disorder treatment — not because wanting to stop is wrong, but because the body's chemistry changes faster than most people expect.
If You're Thinking About Stopping
If part of you is thinking about stopping Suboxone — because you're feeling stable, because of side effects, because of stigma, or for any other reason — that's a completely understandable thing to bring up, not something to hide from your provider. The safest path is a conversation about a supervised taper: a gradual, individualized dose reduction plan that gives your body time to adjust and lets your provider watch for withdrawal or cravings along the way. Ask us about our approach to tapering if you'd like to learn more about what that process looks like.
And if you've already stopped on your own, or you've had a relapse, please reach out to your provider. National treatment guidance from SAMHSA specifically recommends promptly resuming medication after a relapse — getting back into care quickly is protective, not a sign of failure. Our team's job is to help you stay safe, whatever that looks like for you right now.
If you or someone else is experiencing an overdose (signs include slowed or stopped breathing, blue lips or fingertips, unresponsiveness), call 911 immediately. If naloxone (Narcan) is available, administer it while waiting for emergency help.
