Three FDA-approved medications treat opioid use disorder, and they work in genuinely different ways. Understanding the differences helps you have a smarter conversation with a provider — who ultimately decides, with you, which one is clinically appropriate. This is educational information, not a recommendation; no medication is right for everyone.

Buprenorphine (Suboxone) Methadone Naltrexone (Vivitrol) Quick comparison How a provider chooses Your next stepBuprenorphine / Suboxone
A partial opioid agonist: it quiets cravings and withdrawal but has a ceiling that limits its opioid effect, which makes overdose less likely and allows office-based and telehealth prescribing. It's often the most accessible option — many people can start it from home in California. The trade-off is timing at the start: it has to be begun carefully to avoid discomfort (see how starting works).
Methadone
A full opioid agonist — highly effective, especially for people with long or severe opioid histories. The trade-off is structure: methadone is dispensed through specialized, federally regulated opioid treatment programs, which often means daily in-person visits at a clinic, at least early on. That structure helps some people and is a barrier for others.
Naltrexone / Vivitrol
An opioid antagonist — it blocks opioid receptors entirely, so opioids have no effect while it's active. It's available as a monthly injection (Vivitrol). The catch is the starting line: you must be fully off opioids and through withdrawal before beginning it, or it can trigger severe precipitated withdrawal. It's a strong fit for people who are already detoxed and want a non-opioid option.
A quick side-by-side
In broad strokes: buprenorphine — partial agonist, home/telehealth-friendly, good all-around first option for many. Methadone — full agonist, clinic-based, powerful for severe or long-standing use. Naltrexone — a blocker, no opioid activity, requires being fully detoxed first. None is 'stronger' or 'better' in the abstract — they fit different people and situations.
How the choice actually gets made
A provider weighs your history, how severe and how recent your use is, other health conditions, what access looks like for you, and your own preferences and goals. The best medication is the one you'll actually stay on and that keeps you stable and safe. That's a conversation, not a formula — and it's a medical decision, made with a licensed provider.

Frequently asked questions
Which MAT medication is best?
There's no single best — buprenorphine, methadone, and naltrexone fit different people and situations. A licensed provider helps you choose based on your history, health, access, and goals. The best one is the one that keeps you stable and that you'll stay on.
Is Suboxone or methadone stronger?
They work differently rather than one being simply 'stronger.' Methadone is a full agonist often used for severe or long-standing use through structured clinics; buprenorphine is a partial agonist that's more accessible, including via telehealth. Both are highly effective.
Can I switch medications later?
Sometimes — if one isn't working well for you, a provider can discuss transitioning to another, which has to be done carefully and under medical supervision. Your plan isn't locked in forever.
Which one can I start from home?
Buprenorphine is the option most often started via telehealth in California. Methadone requires a specialized clinic, and naltrexone requires being fully detoxed first. A provider confirms what's appropriate for you.
