Methadone and Suboxone can help people safely end opioid use. The drugs are both opioids, but they differ in their active ingredients and how they work in the body.
Article at a Glance:
- Methadone and Suboxone are bothmedication-assisted treatment (MAT)options for opioid use disorder.
- The drugs are both opioids, but they differ in their active ingredients and how they work in the body.
- Methadone is only available from specialty facilities, while Suboxone can be dispensed by a regular pharmacy.
- These drugs should not be used together because Suboxone can cause a person on methadone to go into withdrawal.
Is Suboxone the Same as Methadone?
Suboxone(the brand name for buprenorphine/naloxone) andmethadoneare two popular medications used to treat opioid addictions. Both can be used as part of drug replacement therapy, in which they replace more potent opioids likeheroinormorphine. Because someone with a severe opioid dependence can face severe health risks if they quit “cold turkey,” these replacement medications are used to help wean patients off gradually and safely.
While both drugs are used as part of drug detox and recovery treatment, they differ slightly in their benefits and risks. The following provides an overview of the differences between methadone and Suboxone and discusses how these medications can be used as part of a safe opioid rehab program.

Treatment With Methadone
The goal ofmethadone treatmentis to help people manage opioid addiction side effects in a controlled manner. Methadone acts on the same mu opioid brain receptors as other opioids, but it lasts longer and has a cumulative effect over time. The result is fewer cravings and diminished withdrawal symptoms.
After a maintenance period, the amount of methadone used in treatment is reduced until the person is able to manage side effects without it. However, some people may continue taking methadoneindefinitely.
Advantages of Methadone
Methadone’s major advantage is its ability to satiate opioid cravings in a relatively controlled way. It is classified as a “full agonist opioid,” meaning it fully stimulates the opioid receptors in the brain. This is particularly useful for severe cases ofopioid addictionthat may not be as responsive to other types of drug replacement therapy. This effect also allows methadone to block the euphoric effects of other opioids, such as heroin and prescription painkillers.
Disadvantages and Risks of Methadone Treatment
Methadone is generally considered safer than many other opioids, but it is still a drug thatcarries a riskof dependence and abuse. While methadone helps far more people than it harms, methadone addiction and overdose are risks that must be managed. This is why methadone is typically dispensed in a highly controlled, clinical environment — it allows for supervised methadone administration and minimizes abuse risks. However, this can also make it more difficult for some people to receive treatment, as they must physically visit a clinic or medical facility for each dose.
Treatment With Suboxone
Suboxone is a comparatively new option for treating opioid addiction. It is the brand name for a medication that actually contains two separate drugs: buprenorphine and naloxone.
Buprenorphine
Like methadone,buprenorphineis an opioid that is used as part of opioid drug replacement therapy. It is classified as a “partial agonist opioid,” meaning it binds to the brain’s opioid receptors but does not fully stimulate them like methadone or other opioids can. This results in less of a drug high.
Naloxone
Naloxone, also known by the brand nameNarcan, is a medication that blocks the effect of opioids. On its own, it is often used to treat opioid overdose and help mitigate its life-threatening health risks. When taken by mouth, naloxone ispoorly absorbed. It is added to Suboxone toreduce the riskthat a person will try to misuse the drug by injecting it, as doing so will block opioid receptors and cause withdrawal symptoms.
Advantages
Because it is only a partial agonist, the buprenorphine in Suboxone has a “ceiling effect.” This means that the opioid’s effects will level off after a certain point, even if more of the drug is consumed. This built-in limit to the opioid’s euphoric effects reduces the physiological incentive to take more. The intended result is a lower risk of dependence, abuse and side effects. Buprenorphine also blocks mu opioid receptors, which has the benefit of directly blocking the effects of other, more dangerous opioids if they are also used.
Because Suboxone is takenby mouthas an oral tablet or film, the naloxone does not have a significant effect — it is poorly absorbed by the body when taken orally. Its primary purpose is to prevent people from injecting the opioid for an increased high. When someone injects Suboxone, the naloxone is more readily processed and will effectively block the effects of the buprenorphine.
When a person’s abuse risks are deemed to be low, the person may be able to take Suboxone on their own like a typical prescription. This allows for more flexibility and ease than methadone, which usually must be dispensed in a clinical environment.
Disadvantages and Risks
Because it is a partial agonist, Suboxonemay not be as effective as methadonefor managing cravings and withdrawal side effects in more severe addiction cases. Additionally, although buprenorphine is considered a relatively safe option for addiction treatment, it is still an opioid that carries its own side effects and risks for dependence.
Side Effects and Withdrawal Symptoms Comparison
Methadone and Suboxone are both opioids and have similar side effects.
| Side Effect | Methadone | Suboxone |
|---|---|---|
| Slow heartbeat | X | |
| Heart rhythm problems | X | |
| Confusion | X | X |
| Dizziness | X | X |
| Sedation | X | X |
| Decreased libido | X | |
| Constipation | X | X |
| Nausea/vomiting | X | X |
| Dry Mouth | X | |

Side effects may increase in severity when medications are used in excess or in ways other than prescribed.
Both medications can also cause physical dependence, so it is possible for people to experience withdrawal symptoms when ending the use of either drug. However, there is little data available on withdrawal symptom differences between the drugs.
