Key takeaway

You are trying to choose between methadone and buprenorphine, or you are about to stop one so you can start the other. Methadone for opioid use disorder comes from a certified clinic. Many clinicians can prescribe buprenorphine. Tonight, ask which doorway you can reach, and do not switch at home.

You are trying to choose between methadone and buprenorphine, or someone told you to stop one tonight so you can start the other. A home switch is how people end up in sudden withdrawal, or without a medicine at all.

If breathing is slow, someone will not wake, or you suspect an overdose, call 911. Use naloxone if you have it. What an opioid overdose looks like belongs in that hour. For a mental health crisis, call or text 988.

Tonight, ask a prescriber or a certified opioid treatment program which doorway you can actually reach. Do not stop one medicine to test the other.

Two medicines, two doorways

SAMHSA calls methadone a long-acting full opioid agonist and says that, for opioid use disorder, it is dispensed only through a certified opioid treatment program. It calls buprenorphine a partial agonist and says a clinician can prescribe it in an office, which is also true at those programs. NIDA says the two can be equally effective at helping people reduce opioid use, that both help people stay in treatment, and that methadone may help some people stay longer.

Methadone activates the same receptors as heroin and fentanyl, more slowly, and it stays in the body longer, so withdrawal and craving ease without the same intense high. Buprenorphine activates those receptors less strongly and can block other opioids from attaching. At low to moderate doses its effects, including slowed breathing, are weaker than a full agonist. Weaker is not harmless. Mixing buprenorphine with alcohol, sedatives, or other drugs that slow breathing can cause overdose, especially in large amounts. Do not share either medicine.

Both can cause dependence. Stopping either one suddenly can bring withdrawal. NIDA says that withdrawal is milder than withdrawal from other opioids, and that a clinician should lower the dose. Do not design that reduction from an article. The medication overview also covers naltrexone, which blocks receptors instead of activating them. Read methadone treatment for the clinic window. The Suboxone film combines buprenorphine with naloxone. If you are comparing these two agonists, leave naltrexone in the other column.

Where you can actually get them

People starting methadone usually go to the program every day or almost every day. Since 2020, many people already in treatment may receive up to 28 take-home doses. The program decides. That is not a calendar to copy for a trip.

Buprenorphine does not have to start at that window. Many physicians, nurse practitioners, and physician assistants can prescribe it, including by telehealth since the COVID-19 pandemic. The old federal waiver that limited those prescribers is gone. State rules can still differ, and a pharmacy that does not stock the medicine is a separate barrier. Tablets, films, injections, and implants are all buprenorphine products. Some people start with a telehealth visit. Heroin treatment and opioid care cover the wider map. Neither one is a switch you do at home.

Do not start buprenorphine while the other opioid is still active

SAMHSA says buprenorphine is started when a person is already in early withdrawal, because starting it while other opioids are still active can precipitate acute withdrawal. The prescriber watches the signs and chooses the timing. Do not stop methadone, skip days, or take a saved strip to see what happens. If you miss medicine and then return to illicit opioids, tolerance may be lower. Call the prescriber before you restart on your own.

Pregnancy is not a reason to stop

SAMHSA says methadone and buprenorphine are the treatments of choice for pregnant and breastfeeding women with opioid use disorder. CDC says not to stop opioids quickly in pregnancy. A family argument or a brochure that prefers one medicine is not a stop order. Care during pregnancy carries that warning further.

Common Questions

Is methadone a full agonist and buprenorphine a partial one?

SAMHSA calls methadone a long-acting full opioid agonist and calls buprenorphine an opioid partial agonist. NIDA says both bind to mu-opioid receptors. Methadone activates those receptors more slowly than heroin or fentanyl and stays in the body longer. Buprenorphine activates the same receptors to a lesser degree and can block other opioids from attaching. Neither description is a dose.

Which one works better?

NIDA says methadone and buprenorphine can be equally effective at helping people reduce opioid use, and that both help people stay in treatment. It also says methadone may help some people stay longer. Those are research summaries. They are not a reason to switch medicines without the prescriber.

Why is methadone harder to pick up than buprenorphine?

SAMHSA says methadone for a confirmed opioid use disorder can be dispensed only through a certified opioid treatment program. Buprenorphine can be prescribed in an office and can also be given at those programs. Many physicians, nurse practitioners, and physician assistants can prescribe it, including by telehealth. The old federal waiver that limited buprenorphine prescribers is gone. State rules can still differ.

Are both used in pregnancy?

SAMHSA says buprenorphine and methadone are the treatments of choice for opioid use disorder in pregnant and breastfeeding women. NIDA cites research in which infants whose mothers were treated with buprenorphine were less likely to have neonatal opioid withdrawal syndrome or low birth weight than infants whose mothers were treated with methadone. That study is not an instruction to switch. CDC says not to stop opioids quickly in pregnancy.

How many people with opioid use disorder get these medicines?

NIDA says fewer than 1 in 5 do. Distance from a methadone program, pharmacies that do not dispense buprenorphine, and stigma are among the reasons it lists. Tell the assessor which setting you can actually attend. People treated with either medicine are less likely to die of overdose than people who receive no treatment, in the research NIDA summarizes.
