Suboxone vs. Vivitrol: How to Choose Between The Two

Complete Healthcare Team

The single biggest difference between Suboxone and Vivitrol isn’t how well they work. It’s what you have to do before you can start. Vivitrol requires you to be fully detoxed and off all opioids for about 7 to 10 days before your first dose, while Suboxone can be started while you’re still in withdrawal. That one difference shapes almost everything else about choosing between them, and it’s the piece people most often don’t realize until they’re already trying to decide.

Both are effective, FDA-approved medications for opioid use disorder, and neither is simply “better.” They work in opposite ways and suit different situations. The Suboxone team at Complete Healthcare helps people weigh this choice regularly, and this guide breaks down how each one works, what the research shows, and which tends to fit which circumstances.

How They Work: Opposite Approaches

The core distinction is pharmacological, and it’s worth understanding plainly because everything else follows from it.

Suboxone contains buprenorphine, a partial opioid agonist, combined with naloxone. Buprenorphine partially activates the same brain receptors that opioids target, which reduces cravings and withdrawal without producing a strong high. In simple terms, it satisfies the receptor enough to keep withdrawal and cravings at bay.

Vivitrol is the brand name for extended-release naltrexone, an opioid antagonist. Instead of activating opioid receptors, it blocks them entirely. While Vivitrol is in your system, opioids can’t produce their usual effect, which removes much of the incentive to use. It doesn’t reduce cravings by satisfying the receptor. It works by making opioids not work.

That difference, activating versus blocking, is the root of every practical tradeoff between them.

The Detox Requirement: The Deciding Factor for Many

Because Vivitrol blocks opioid receptors, taking it while opioids are still in your body will trigger sudden, severe withdrawal. That’s why you have to be fully detoxed, generally 7 to 10 days opioid-free, before starting it. For someone in active opioid use, getting through that window is genuinely hard, and it’s the single biggest hurdle to starting Vivitrol.

Suboxone doesn’t have this barrier in the same way. It’s typically started once you’re in early withdrawal, often within a day of your last use, which means you can begin treatment much sooner and get relief from withdrawal symptoms quickly. For many people in active use, that accessibility is decisive.

What the Research Actually Shows

Being honest about the evidence matters here, and there’s a landmark study that speaks directly to this comparison. In a large randomized trial known as X:BOT, published in The Lancet in 2018, researchers compared the two medications in 570 people. The key finding was nuanced: naltrexone was harder to start, with only about 72 percent of the Vivitrol group successfully initiating treatment compared with 94 percent of the Suboxone group, largely because of the detox requirement.

But here’s the part that matters just as much: once people successfully started either medication, the two were similarly safe and effective at preventing relapse. In other words, the main disadvantage of Vivitrol is getting onto it, not how it performs once you’re on it. This is why the starting point of your situation matters so much in the choice.

Other Key Differences

Beyond mechanism and detox, a few practical distinctions shape the decision:

• Dosing schedule. Suboxone is usually taken daily as a film or tablet under the tongue. Vivitrol is a once-monthly injection given by a provider, which removes daily decision-making but requires a monthly appointment.
• Controlled substance status. Suboxone contains buprenorphine and is a Schedule III controlled substance. Vivitrol is not a controlled substance and carries no potential for misuse or dependence, since it’s a blocker.
• What they treat. Both treat opioid use disorder. Vivitrol is also FDA-approved for alcohol use disorder, so it can be a strong option for someone dealing with both.
• Stopping the medication. Because buprenorphine is an opioid, stopping Suboxone abruptly can cause withdrawal, so it’s tapered. Vivitrol can be stopped without physical withdrawal from the medication itself.

Which One Tends to Fit Which Situation

Neither is universally right, but the fit often becomes clearer based on circumstances. Here’s how it tends to break down.

Suboxone is frequently a better fit for people in active opioid use who need relief now and can’t realistically get through a 7 to 10 day detox first, and for people who find that reducing cravings directly helps them stabilize. Vivitrol often suits people who have already completed detox, such as those leaving inpatient treatment or incarceration, and people who specifically want a non-opioid, non-controlled medication or who are also managing alcohol use. In our practice, we find the right choice usually emerges from where someone is starting from, their history, and their preferences, rather than from one medication being superior on paper.

Common Questions About Suboxone and Vivitrol

Which is more effective, Suboxone or Vivitrol?

Once a person successfully starts either one, research shows they are similarly effective at preventing relapse. The practical difference is that Suboxone is easier to begin, since Vivitrol requires full detox first, which means fewer people successfully get started on Vivitrol. So in real-world terms, Suboxone has an accessibility advantage, but for someone who has already detoxed, both are strong options. The better choice depends on your situation rather than one being clinically superior across the board.

Can you switch from Suboxone to Vivitrol?

Yes, and people do. Because Vivitrol is an opioid blocker, switching requires tapering off Suboxone and then completing a period fully off opioids, including buprenorphine, before the first Vivitrol injection. If Vivitrol is started too soon, it can trigger withdrawal. This transition is very doable, but it needs to be planned and monitored by your provider so the timing is right.

Is Vivitrol just a stronger version of Suboxone?

No, and this is a common misunderstanding. They aren’t stronger or weaker versions of the same thing. They work in opposite ways, one partially activates opioid receptors while the other blocks them entirely. They shouldn’t be taken together, and the choice between them is about which mechanism fits your circumstances, not about potency.

What This Means for Insurance and Access

Cost and coverage can differ between the two, since they’re different medications with different delivery methods, and Vivitrol’s monthly injection can carry different coverage considerations than a daily prescription. Rather than guessing, it’s worth having benefits checked directly, and our staff can help verify your coverage for either option before you start so cost isn’t an unexpected barrier.

Figuring Out Which Is Right for You

The best way to sort through this choice is with a provider who can look at your history, where you are right now, and what matters most to you.
