Suboxone vs methadone: What’s the difference?

Medically reviewed by Leigh Ann Anderson, PharmD. Last updated on March 24, 2025.

Official Answer by Drugs.com

Suboxone (buprenorphine and naloxone) and methadone are different medicines but are both used to help people fight opioid addiction (also called opioid use disorder or OUD). Your first treatment after a medically-supervised opioid withdrawal (detox) is often started with either Suboxone or methadone.

People with opioid use disorder can have harmful or even fatal effects from using narcotics, especially if they have slowed down or stopped opioid use, and then start using opioids again.

Suboxone

Suboxone is a brand name medicine that contains buprenorphine and naloxone. It comes as a sublingual/buccal oral film (placed under the tongue or between the cheeks and gum) and is given as a single daily dose. It is also available as a generic option.

Suboxone is approved for the first phase of opiate withdrawal (induction or detox) and well as the longer-term maintenance phase. Suboxone eases drug cravings and helps to prevent unpleasant symptoms (withdrawal) after you stop using narcotics.

Suboxone is not FDA-approved for the treatment of pain, but might be prescribed "off-label" by some doctors for certain patients. “Off-label" use of a drug refers to when a doctor prescribes a medicine for a different purpose than those formally approved by the FDA and found in the package labeling.

Suboxone is classified as a schedule III medication by the DEA because it contains buprenorphine, an opiate, and is considered a drug that can be abused. Since it is not a full opioid agonist, Suboxone tends to cause less fatigue and it may be it easier to slowly discontinue this medicine.
