Suboxone: How This Opioid Addiction Medication Works
What Suboxone is, how this buprenorphine and naloxone medication treats opioid addiction, how it is taken as a sublingual film, and its place in medication-assisted treatment.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Suboxone is a prescription medication used to treat opioid addiction (opioid use disorder), and it is one of the most effective tools in medication-assisted treatment (MAT). It combines two medicines: buprenorphine, a partial opioid that relieves cravings and withdrawal without producing the strong high of full opioids, and naloxone, an opioid blocker included to deter misuse. Suboxone is most often taken as a thin film (or a tablet) placed under the tongue, where it dissolves and is absorbed sublingually, usually once daily. By acting on the same opioid receptors as drugs like heroin and prescription opioids, the buprenorphine in Suboxone stops cravings and withdrawal, allowing a person to feel normal and function without using illicit opioids, and it dramatically reduces the risk of overdose death. Suboxone is prescribed by a doctor or other authorised healthcare provider and is used as part of a treatment program that also includes counselling and support. It is a safe, evidence-based medication that has transformed opioid addiction treatment, though as an opioid medication it causes physical dependence and must be taken as prescribed, started correctly, and stopped only by gradual tapering under medical guidance.
What is Suboxone?
Suboxone is a prescription medication used to treat opioid addiction, also known as opioid use disorder, and it is one of the most effective and widely used tools in the treatment of addiction to opioids such as heroin, fentanyl, and prescription opioid painkillers. Suboxone is a brand-name combination of two medicines, buprenorphine and naloxone, and it is a central part of what is called medication-assisted treatment, or MAT, the use of medication alongside counselling and support to treat opioid addiction. Suboxone works by relieving the cravings and withdrawal symptoms that make stopping opioids so difficult, allowing a person to stabilise, feel normal, and rebuild their life in recovery, while dramatically reducing the risk of fatal overdose.
This article explains what Suboxone is, how it works to treat opioid addiction, how it is taken, in particular as a film placed under the tongue, and its place in medication-assisted treatment, as well as the key points to understand about it. Suboxone has transformed the treatment of opioid addiction, offering a safe, evidence-based approach that saves lives and supports lasting recovery. The aim is a clear, accurate, and practical overview of this important medication, useful for anyone considering it, taking it, or seeking to understand opioid addiction treatment. Understanding how Suboxone works and how it is used can help reduce stigma and encourage people to access this life-saving treatment.
How Suboxone works
Suboxone works mainly through buprenorphine, a partial opioid. This means buprenorphine acts on the same opioid receptors in the brain as full opioids like heroin and oxycodone, but only partially activates them. This partial action is enough to relieve the cravings and withdrawal symptoms that drive continued opioid use, but it does not produce the strong high, euphoria, and dangerous effects of full opioids. As a result, a person on Suboxone can feel normal, neither intoxicated nor in withdrawal, free of cravings, and able to function and live a normal life, without the cycle of using illicit opioids. Buprenorphine also has a ceiling effect, meaning its effects level off above a certain dose, which makes it much safer than full opioids and greatly reduces the risk of fatal overdose from the medication itself.
The second medicine in Suboxone, naloxone, is an opioid blocker, the same medication used to reverse opioid overdoses. When Suboxone is taken correctly, dissolved under the tongue, the naloxone has little effect; it is included to deter misuse, because if someone tried to misuse Suboxone by injecting it, the naloxone would block the opioid effect and could trigger withdrawal, removing the incentive to misuse it that way. Together, buprenorphine’s partial opioid action and ceiling effect, and the naloxone’s misuse-deterrent role, make Suboxone a safer, effective treatment for opioid addiction. By satisfying the opioid receptors in a controlled, safer way, Suboxone breaks the grip of cravings and withdrawal that keeps people trapped in opioid addiction, allowing recovery to begin.

How Suboxone is taken: the sublingual film
Suboxone is most often taken as a thin film, and also comes as a tablet, that is placed under the tongue, where it dissolves and the medication is absorbed through the lining of the mouth, a route called sublingual administration. The film is placed under the tongue (or, in some formulations, against the inside of the cheek) and left to dissolve completely, rather than being chewed or swallowed, because the medication is absorbed through the mouth rather than the stomach. It is usually taken once daily, as buprenorphine is long-acting, and the person should avoid eating or drinking while the film dissolves. This sublingual method is how the medication is delivered effectively.
The dose of Suboxone is determined by the prescribing doctor or healthcare provider and adjusted to the level that effectively controls the person’s cravings and withdrawal. Treatment usually begins with an induction phase, in which Suboxone is started, importantly at the right time, when the person is already in mild to moderate opioid withdrawal, to avoid a problem called precipitated withdrawal (a sudden, sharp withdrawal that can occur if Suboxone is started while full opioids are still strongly present in the body). The dose is then stabilised at a maintenance level that keeps the person comfortable and free of cravings, and treatment is often continued for an extended period, sometimes long-term, as ongoing treatment is associated with the best outcomes. Throughout, Suboxone should be taken exactly as prescribed.
Suboxone in medication-assisted treatment
Suboxone is used as part of medication-assisted treatment (MAT), the combination of medication with counselling and behavioural support to treat opioid addiction. While the medication is highly effective on its own at reducing cravings, withdrawal, and overdose risk, it is most effective as part of comprehensive treatment that also addresses the psychological, behavioural, and social aspects of addiction. So Suboxone is typically prescribed within a treatment program that includes counselling, behavioural therapy, and support, helping the person not only stabilise on the medication but also address the underlying issues, develop healthier coping, and rebuild their life. Suboxone can be prescribed by doctors and other authorised healthcare providers, often allowing treatment to be accessed and continued in a range of settings, including being taken at home, which has helped expand access to this treatment.
Suboxone, along with the similar treatments methadone and buprenorphine alone, is a cornerstone of opioid addiction treatment, and the evidence strongly supports medication-assisted treatment as the most effective approach for opioid addiction, far more effective than attempts to treat it without medication. Most importantly, treatment with buprenorphine, as in Suboxone, substantially reduces the risk of death from opioid overdose, genuinely saving lives, as well as helping people stabilise, stay in treatment, reduce or stop illicit opioid use, and rebuild their health and lives. Importantly, taking Suboxone is not simply swapping one addiction for another, a harmful misconception; it is an evidence-based medical treatment that stabilises the person and removes the dangers of illicit opioid use, much as medication manages other chronic conditions. Expanding access to it is a key part of addressing the opioid crisis.
Key points and getting help
While Suboxone is much safer than full opioids, it is still an opioid medication, and there are important points to understand. As an opioid, buprenorphine causes physical dependence, so a person taking Suboxone regularly will experience withdrawal if it is stopped suddenly, which is why it should be stopped only gradually, by tapering under medical guidance, when the time is right, rather than abruptly. It must be started correctly to avoid precipitated withdrawal, taken exactly as prescribed, and never combined with other central nervous system depressants such as benzodiazepines or alcohol without medical guidance, as these combinations can suppress breathing dangerously. Suboxone also has side effects, which can include headache, nausea, constipation, and sweating, and it must be kept safely away from children and others, for whom it can be dangerous.
These points are important but manageable when Suboxone is used correctly under medical supervision, and they are far outweighed by the benefits of effective treatment for opioid addiction. If you or someone you love is struggling with opioid addiction, Suboxone is one of the most effective treatments available, and it is well worth discussing with a doctor or addiction specialist. It offers a genuine, evidence-based, life-saving path out of the dangerous cycle of opioid addiction toward lasting recovery. Reaching out for help is a positive and potentially life-saving step, and with medication-assisted treatment such as Suboxone, alongside counselling and support, recovery from opioid addiction is genuinely achievable. No one should be deterred from this effective treatment by stigma or misconceptions, because it saves lives and supports real recovery.

As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “Suboxone is one of the most life-saving medications I prescribe. The buprenorphine in it is a partial opioid that switches off the cravings and withdrawal driving people back to heroin or fentanyl, without the dangerous high, and with a safety ceiling that makes overdose far less likely. People take it as a film that dissolves under the tongue, usually once a day, and on the right dose they simply feel normal and can get on with their lives and their recovery. The myth that it is just swapping one drug for another costs lives, it is the opposite. Combined with counselling, it transforms opioid addiction treatment and dramatically cuts the risk of dying.”
Frequently asked questions
What is Suboxone used for?
Suboxone is used to treat opioid addiction (opioid use disorder), as a central part of medication-assisted treatment (MAT). It helps people addicted to opioids such as heroin, fentanyl, and prescription opioid painkillers by relieving the cravings and withdrawal symptoms that make stopping so difficult, allowing them to stabilise and function normally without using illicit opioids. It combines buprenorphine, a partial opioid that treats the addiction, and naloxone, included to deter misuse. Suboxone is a highly effective, evidence-based treatment that significantly reduces the risk of overdose death and supports recovery, used alongside counselling and support. It is one of the most important tools available for treating opioid addiction and helping people recover and rebuild their lives.
How do you take Suboxone film?
Suboxone is most often taken as a thin film placed under the tongue, where it dissolves and the medication is absorbed through the lining of the mouth (sublingual administration); it also comes as a tablet taken the same way. The film is placed under the tongue (or, in some formulations, against the inside of the cheek) and left to dissolve completely, rather than being chewed or swallowed, because it is absorbed through the mouth, not the stomach. It is usually taken once daily, and you should avoid eating or drinking while it dissolves. The dose is set by your doctor and taken exactly as prescribed. Taking it correctly, allowing it to dissolve fully under the tongue, ensures the medication is absorbed and works effectively.
Is Suboxone just replacing one addiction with another?
No, this is a common but harmful misconception that can deter people from this life-saving treatment. Suboxone is an evidence-based medical treatment, not simply a substitute drug. While buprenorphine is an opioid and causes physical dependence, on an effective dose a person is stabilised, not intoxicated, free of cravings and withdrawal, and able to function normally, without the dangerous high and overdose risk of illicit opioids. It treats the addiction much as medication manages other chronic conditions, and dramatically reduces the risk of overdose death. So Suboxone is not just swapping one addiction for another; it is a safe, effective treatment that stabilises people, removes the dangers of illicit opioid use, and supports recovery, which is the opposite of continued addiction.
How does Suboxone reduce overdose risk?
Suboxone reduces overdose risk in several ways. The buprenorphine in it relieves cravings and withdrawal, which reduces the likelihood of returning to illicit opioids, where overdose is a constant danger, especially with contaminated supplies containing fentanyl. As a partial opioid, buprenorphine also has a ceiling effect, where its effects, including the suppression of breathing, level off above a certain dose, making it much safer in overdose than full opioids. And by stabilising the person and keeping them in treatment, it supports a recovery that moves them away from the dangers of illicit opioid use. The evidence strongly shows that treatment with buprenorphine, as in Suboxone, substantially reduces the risk of death from opioid overdose, genuinely saving lives.
Can you get addicted to Suboxone?
Suboxone is an opioid medication and causes physical dependence, meaning the body adapts to it and stopping suddenly causes withdrawal, so it should be stopped only by gradual tapering under medical guidance. However, this physical dependence in the context of treatment is different from the destructive addiction to illicit opioids it treats: on an effective dose, a person is stabilised and functioning normally, not engaged in the compulsive, harmful use that defines addiction. Because of the partial opioid action, ceiling effect, and naloxone, Suboxone has a lower potential for misuse than full opioids and is taken in a controlled, supervised way. So while Suboxone causes dependence, it is a treatment that frees people from the dangerous addiction to illicit opioids, not a continuation of it.
Who can prescribe Suboxone?
Suboxone is prescribed by doctors and other authorised healthcare providers as part of medication-assisted treatment for opioid addiction. The ability to prescribe buprenorphine-based treatments like Suboxone has expanded over time, allowing more healthcare providers in more settings to offer it, which has helped improve access to this life-saving treatment, including allowing it to be prescribed and taken in office-based and community settings, and at home, rather than only at specialised clinics. A person seeking Suboxone treatment can start by contacting a doctor, an addiction treatment service, or a helpline, which can help them access a prescriber and a treatment program. Expanding access to Suboxone and other medications for opioid addiction is a key public health priority in addressing the opioid crisis.
