Medication for opioid use disorder, commonly abbreviated MOUD, refers to FDA-approved medications used to treat opioid use disorder. The three main medication options are methadone, buprenorphine, and naltrexone. They work in different ways but are all evidence-based treatments that can reduce opioid cravings, support treatment retention, and lower the risk associated with untreated opioid use disorder.
What medications are considered MOUD?
SAMHSA identifies three FDA-approved medication categories for opioid use disorder: methadone, buprenorphine, and naltrexone.
- Methadone is a long-acting full opioid agonist.
- Buprenorphine is a partial opioid agonist.
- Naltrexone is an opioid antagonist that blocks opioid effects.
Why is the term MOUD used instead of MAT?
SAMHSA explains that the term “medications for opioid use disorder” emphasizes that these medications are core evidence-based treatments rather than merely an add-on to counseling. The older term “medication-assisted treatment,” or MAT, is still used, but many clinicians and agencies now prefer MOUD.
How does MOUD help?
Depending on the medication, MOUD can reduce withdrawal symptoms, cravings, or the rewarding effects of opioids. Methadone and buprenorphine stabilize opioid receptors, while naltrexone blocks them.
Medication can be combined with counseling, recovery support, psychiatric care, medical care, and social services based on individual needs.
Does MOUD mean replacing one drug with another?
No. When used as prescribed, methadone and buprenorphine are medical treatments for a chronic condition. Physical dependence on a medication is not the same as compulsive use despite harm.
How long can someone stay on MOUD?
There is no universal maximum length of treatment. SAMHSA states that MOUD may be used for months, years, or longer when clinically appropriate. Decisions about dose reduction or discontinuation should be individualized.
Where can MOUD be provided?
Buprenorphine and naltrexone can be prescribed in many medical settings. Methadone for opioid use disorder is generally dispensed through a federally certified opioid treatment program.
Can MOUD be used during residential treatment?
It can be, depending on the facility’s capabilities and the individual treatment plan. Federal guidance supports continuing evidence-based OUD medication rather than requiring unnecessary discontinuation. However, a residential facility’s actual medication capabilities should always be verified directly.

Frequently asked questions
Is naloxone considered MOUD?
No. Naloxone is an emergency opioid-overdose reversal medication, not a maintenance treatment for opioid use disorder.
Is detox medication the same as MOUD?
Not necessarily. Medications used only to treat short-term withdrawal symptoms are different from medications used to treat the underlying opioid use disorder.
Can someone receive MOUD without counseling?
Medication should be part of a patient-centered treatment plan, but access to medication should not be withheld simply because counseling is unavailable or declined when the medication is otherwise clinically appropriate.
Are all three MOUD medications opioids?
No. Methadone and buprenorphine are opioid medications. Naltrexone is an opioid antagonist and does not activate opioid receptors.
