Alcohol and Suboxone: What You Need to Know

Have questions about your own situation? A board-certified physician can talk through your drinking history and treatment plan with you, confidentially.

If you’re being treated with Suboxone (buprenorphine/naloxone) for opioid use disorder, alcohol is one of the substances you’ll hear the strongest warnings about, and for good reason. Unlike some of the more nuanced medication interactions covered in our guide to Suboxone drug interactions, alcohol and Suboxone fall into a straightforward category: don’t combine them. This article breaks down why, what the actual risks look like, and what to do if alcohol use is already part of your picture.

Can You Drink on Suboxone?

The short answer is no. Suboxone’s prescribing information advises against alcohol use entirely during treatment, not just heavy drinking. Buprenorphine and alcohol are both central nervous system depressants, and even moderate drinking can add to Suboxone’s sedative effects in ways that aren’t predictable from one person, or one occasion, to the next. There’s no established “safe” amount of alcohol to combine with Suboxone, which is different from some other medications where occasional light drinking might be considered lower-risk.

Mixing Alcohol and Suboxone

Combining the two isn’t just discouraged in general terms; there’s a specific physiological reason it’s treated as a hard line.

Why This Combination Is Risky

Suboxone and alcohol both slow down activity in the central nervous system, the part of your body that controls breathing, heart rate, and consciousness. On their own, each substance carries some sedative effect. Combined, those effects don’t just add up; they can compound each other in ways that are hard to predict, especially since alcohol’s effects can shift quickly depending on how much and how fast you drink.

What Happens in Your Body

Alcohol already has wide-ranging effects on the body on its own, from the liver to the heart to the brain. Add buprenorphine into the mix, and you’re at increased risk of:

• Respiratory depression. Both substances can slow your breathing, and together they raise the risk of dangerously shallow or slowed breaths.
• Excessive sedation. Extreme drowsiness, dizziness, and difficulty staying alert or awake.
• Low blood pressure. Alcohol combined with buprenorphine can contribute to hypotension, which can cause fainting or lightheadedness.
• Impaired coordination and judgment. Both substances affect motor control and decision-making, which compounds when combined.

In more severe cases, this combination has been associated with coma and death, which is why it’s treated as a firm no rather than a “proceed with caution.”

Suboxone and Alcohol Side Effects

The effects of combining alcohol and Suboxone range from uncomfortable to genuinely dangerous, and it’s worth knowing where that line is.

Short-Term Effects

Even a single drinking episode while on Suboxone can bring on noticeable effects beyond what either substance would cause alone: heavier sedation than usual, nausea or vomiting, confusion, slowed or labored breathing, and impaired balance or coordination. Because of how long Suboxone stays in your system, timing your drinking around your dose doesn’t meaningfully reduce the risk.

When to Seek Medical Help

Call 911 or go to an emergency room if you or someone you’re with shows any of the following after drinking while on Suboxone:

• Breathing that’s slow, shallow, or irregular
• Blue-tinged lips or fingertips
• Difficulty waking up or staying conscious
• Vomiting while drowsy or unresponsive (a choking risk)
• Confusion, slurred speech, or extreme disorientation

These are signs of an overdose or dangerous CNS depression, and they need emergency care, not a “wait it out” approach.

Suboxone and Alcohol Withdrawal

Withdrawal is where alcohol and Suboxone diverge most, and it’s the part of this topic that most needs a provider’s involvement.

Why Timing and Supervision Matter

Alcohol withdrawal is different from opioid withdrawal in one critical way: it can be medically dangerous, even fatal, if it isn’t managed properly. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), alcohol withdrawal is a potentially life-threatening process for people who’ve been drinking heavily over a prolonged period. Our alcohol withdrawal timeline guide breaks this down in more detail, but broadly, symptoms typically begin within 6 to 24 hours of the last drink and can include tremors, anxiety, and a racing heart. In more severe cases, withdrawal can progress to seizures or delirium tremens (DTs), a medical emergency involving severe confusion, hallucinations, and dangerous shifts in heart rate and blood pressure, usually peaking 48 to 72 hours after the last drink.

If you’re stopping both opioids and alcohol at the same time, or starting Suboxone while you’re still drinking regularly, this timing needs to be planned with a provider. Suboxone treats opioid withdrawal, not alcohol withdrawal, and the two require different medical approaches.

Managing Withdrawal Safely

Safe management generally involves:

• A medical evaluation of your drinking pattern before starting or continuing Suboxone
• Separate, supervised alcohol withdrawal management if you’re drinking heavily or daily, sometimes with medications like benzodiazepines under close monitoring
• Close coordination between your Suboxone provider and whoever is managing alcohol withdrawal, so both processes are tracked together rather than treated as separate issues
• Monitoring for symptoms that could signal the withdrawal is becoming severe

Never attempt to stop heavy, long-term alcohol use on your own while also managing opioid use disorder treatment. Our Pharmacy Q&A for Suboxone patients has more on how to keep your care team coordinated as you navigate multiple aspects of treatment.

Suboxone and Long-Term or Regular Alcohol Use

Occasional drinking isn’t the only concern. Regular or heavy alcohol use alongside Suboxone treatment raises additional issues over time. Chronic alcohol use can affect liver function, and since buprenorphine is processed by the liver, impaired liver function can change how the medication is metabolized and how long it stays active in your system. Regular drinking can also undercut the stability Suboxone is meant to help you build, making cravings, mood swings, and relapse risk harder to manage.

For some patients, what looks like occasional drinking is actually the early or established stages of alcoholism, now more commonly referred to as alcohol use disorder (AUD), existing alongside opioid use disorder. The distinction between the two terms, and where casual drinking ends and alcohol dependence begins, isn’t always obvious from the inside. If you’re noticing patterns in your own drinking, our guide to the signs of alcohol use disorder can help you get a clearer picture. This is more common than many people realize, and it isn’t something to manage quietly on your own.

Co-occurring AUD and OUD generally respond best to integrated treatment, where both conditions are addressed together rather than one at a time. If this sounds like your situation, our Alcohol Use Disorder treatment program is built to work alongside Suboxone care, and our relapse prevention strategies guide covers tools that apply to managing risk around both substances.
