TL;DR — Medication to Reduce Alcohol Drinking in 2026
Three medications are FDA-approved for alcohol use disorder: naltrexone, acamprosate, and disulfiram. For people who want to drink less rather than quit entirely, naltrexone is typically the first-line choice — it reduces cravings by blocking opioid receptors. Telehealth platforms like Sunnyside Med, Ria Health, and Oar Health now make prescriptions accessible from home.

How It Works |
Price |
| 1 |
Naltrexone (oral) |
First-line for moderation or abstinence. Most evidence behind it. Available via Sunnyside Med, Ria Health, Oar Health, or your regular doctor. |
Blocks opioid receptors; reduces the reward signal that alcohol triggers in the brain. Take daily (50mg). |
~$30–50/mo generic |
| 2 |
Naltrexone (Vivitrol injection) |
People who don’t want to manage a daily pill. Same drug, extended-release. |
Monthly intramuscular injection delivers steady naltrexone levels without daily compliance. Requires an in-office visit. |
~$1,000–1,500/mo (insurance usually covers) |
| 3 |
Acamprosate (Campral) |
Maintaining abstinence after quitting. Less useful if you’re still drinking. |
Restores GABA/glutamate balance disrupted by chronic drinking. Reduces the persistent anxiety and discomfort of early sobriety. Taken 3x daily. |
~$50–75/mo generic |

Why To Know About These Medications
Roughly 2% of people with alcohol use disorder ever get prescribed medication for it. That’s from SAMHSA’s own data. Meanwhile, medications that genuinely work have been sitting on pharmacy shelves for decades.
Why? The American addiction treatment system was largely built around abstinence-based therapy and 12-step programs — both of which have real value, but neither of which involves a prescription pad. Most doctors aren’t trained in addiction medicine. Many patients are embarrassed to bring it up. And historically, there’s been this implicit idea that needing medication to stop drinking is somehow cheating, or not “real” recovery.
That’s slowly changing. Telehealth has been the biggest disruptor — platforms like Sunnyside Med, Ria Health, and Oar Health have made it possible to get a naltrexone prescription from your couch, without walking into an addiction clinic or telling your employer. That’s removed a lot of the friction and stigma that kept people from ever asking.
But the core problem — that doctors don’t offer this proactively — hasn’t changed much. Medication is an extremely underused intervention — honestly, many doctors don’t even bring it up. So you often have to be the one who asks.
Worth knowing before we get into specifics: None of these medications requires you to want to quit entirely. Naltrexone in particular is used widely for people who just want to drink less, who want a glass of wine at dinner without it turning into four. That framing matters. The goal can be moderation, not abstinence, and medication can still help.
Naltrexone: The First-Line Option
If you’ve done any reading on medication for alcohol use, you’ve probably heard about naltrexone. That’s not an accident — it has more clinical evidence behind it than any other option in this category.
When you drink, alcohol triggers a release of endorphins, which bind to opioid receptors in your brain and produce the pleasurable, rewarding feeling that keeps you coming back. Naltrexone blocks those receptors. The alcohol is still in your system, but the reward signal gets dampened. Over time (this is the key mechanism), your brain stops associating drinking with that hit of pleasure, and cravings naturally decline.
The standard dose is 50mg daily. Side effects are real but usually manageable: nausea in about 10–15% of people (typically resolves within the first one to two weeks), some headache, occasional fatigue. Unlike opioid medications, it’s not addictive — you can stop taking it without any withdrawal. And unlike with opioids, you don’t need to be completely abstinent before starting it.
It works for both goals: moderation and abstinence. If you want to cut back, it makes cutting back easier. If you want to stop entirely, it reduces the pull. Sunnyside’s guide on naltrexone goes deeper on what to expect if you’re considering it.
Vivitrol: The Monthly Shot
Vivitrol is extended-release naltrexone administered as an intramuscular injection once a month.
The upside is obvious — you don’t have to remember a pill every day, and blood levels stay consistent throughout the month without the peaks and valleys of a daily oral dose. It also removes the option to stop taking your pills before a planned drinking occasion, which some people do with oral naltrexone.
The downsides are real, though, too. You can’t just stop immediately if you experience side effects — once it’s injected, it’s in your system for the month. It requires an in-office visit (i.e., it can’t be done via telehealth). And the cost without insurance is high. Most insurance plans, including Medicaid, cover it, but navigating prior authorization can be a process.
For people with strong insurance coverage and a history of struggling to stay consistent with daily medications, it’s worth asking about. For people starting out, oral naltrexone is perhaps the more practical first step.
Acamprosate: For After You’ve Already Quit
Acamprosate (brand name Campral) gets less attention than naltrexone, partly because it’s more narrowly useful. It doesn’t do much to reduce active drinking or cravings in people who are still drinking regularly. What it does — and does reasonably well — is help maintain abstinence.
Chronic heavy drinking disrupts the brain’s GABA and glutamate systems. When you stop drinking, that imbalance doesn’t immediately correct itself—your brain can remain in a more excitable state, which is part of why early sobriety often comes with anxiety, poor sleep, and a general sense of unease.
Acamprosate works by modulating glutamate activity and helping stabilize that imbalance, which can reduce the underlying discomfort that makes relapse more likely.
FDA-approved in 2004, it’s taken three times daily, and it’s contraindicated in people with kidney disease. If you’ve gone through medically supervised detox and you’re trying to stay stopped, it’s worth discussing with your doctor. If you’re still in the process of reducing your drinking, naltrexone is probably the more useful tool.
Disulfiram: The Nuclear Option
Disulfiram works completely differently from every other medication on this list. It doesn’t reduce cravings. It doesn’t make drinking less rewarding. It makes drinking physically awful.
When you drink alcohol, your body normally breaks it down through a two-step enzymatic process. Disulfiram blocks the second enzyme (aldehyde dehydrogenase), causing acetaldehyde — a toxic byproduct — to build up in your bloodstream. Drink on it and within 10 to 30 minutes, you’ll experience flushing, sweating, nausea, vomiting, headache, and a racing heart. The reaction can be severe.
It’s a deterrent, not a treatment in the pharmacological sense. It doesn’t change your brain chemistry around alcohol — it just makes the prospect of drinking immediately, physically punishing.
The problem is compliance. You can stop taking it. And you can — after about five days, once it’s cleared your system — drink again without any reaction. Studies on disulfiram outcomes are mixed because so many participants discontinue it. It makes the most sense in tightly supervised situations, or for someone with extremely strong motivation who wants a hard external barrier.
How to Actually Get a Prescription
Any licensed physician or nurse practitioner can prescribe naltrexone. You don’t need a psychiatrist, an addiction specialist, or a clinic. Your primary care doctor can also do it — the barrier is usually their familiarity with the medication, not any regulatory restriction. If you’re interested, you may need to bring it up yourself and mention that you’ve read about it and would like to discuss it. (That’s rarely as awkward as it sounds!)
Telehealth has made this much easier. A few options worth knowing:
- Sunnyside Med — Naltrexone prescription starting at $99/mo ($297/quarter), with the prescription integrated into the Sunnyside app so your medication and drink tracking work together. The behavioral support piece is built in.
- Ria Health — A more comprehensive program including coaching, monitoring, and naltrexone prescriptions. Higher monthly cost, but more hand-holding if you want it.
- Oar Health — Straightforward telehealth naltrexone prescriptions without a full program. Good if you just want the medication and already have support elsewhere.
If you’re already working with a therapist or counselor, they often can facilitate a referral. And if you want to explore what might fit your situation before committing, Sunnyside’s free assessment is a good starting point.
Why Medication + Behavioral Support Works Better Than Either Alone
The medication handles a specific problem: the neurological pull toward drinking. It doesn’t automatically change habits, social contexts, emotional triggers, or the dozen other reasons people drink more than they want to.
That’s why the combination tends to outperform either approach on its own. The landmark COMBINE study, which was published in JAMA in 2006, found that naltrexone combined with behavioral intervention produced significantly better outcomes than naltrexone or therapy alone. The behavioral component didn’t need to be intensive; consistent, supportive check-ins were enough to enhance results.
Practically, this means tracking your drinks matters. Drink tracking alone has been shown to reduce consumption — the act of measuring creates awareness that measurably changes behavior. Pairing that with naltrexone addresses both the habit layer and the neurochemical layer simultaneously.
Sunnyside is built around exactly this combination — the alcohol tracking app has 600,000+ users with 96.7% reporting they drink less. Sunnyside Med layers medication on top of that foundation. The app starts at $8.25/mo ($99/year) with a 15-day free trial and 30-day money-back guarantee. (For context on how medication fits into a broader reduction strategy, this guide on how to drink less covers the full picture.)
Medication isn’t a replacement for behavioral change. But for a lot of people, it’s what makes behavioral change actually stick. The neurological craving is real, it’s not a willpower failure, and treating it as a medical problem — which it is — tends to work better than grinding through the process on will and motivation alone.
Frequently Asked Questions
What is the best medication to stop drinking?
For most people, naltrexone is the first-line choice — it has the strongest clinical evidence, works for both moderation and abstinence goals, and is widely accessible via telehealth. If you’ve already quit and are trying to stay stopped, acamprosate is worth discussing with your doctor.
Does naltrexone really work for alcohol?
Yes — the evidence is pretty robust. A meta-analysis in JAMA covering 53 randomized controlled trials found an 83% reduction in heavy drinking versus placebo. The Cochrane Collaboration rates it as one of the most effective pharmacological interventions for alcohol use disorder. It doesn’t work for everyone, but for most people it meaningfully reduces cravings and the reward associated with drinking.
The most common is nausea. The good news is it usually resolves within the first one to two weeks. Some people also report headache, fatigue, or decreased appetite in the early weeks. Taking it with food can help with the nausea. Serious side effects are rare. It’s not a sedative, it’s not addictive, and it doesn’t affect your cognition the way some other medications do.
How do I get a naltrexone prescription?
A few routes: your primary care doctor can prescribe it — just bring it up directly. Telehealth platforms like Sunnyside Med (starting at $99/mo), Ria Health, or Oar Health can get you a prescription without an in-person visit. You don’t need an addiction specialist or a formal diagnosis at a clinic. If you’re unsure where to start, Sunnyside’s free assessment can help clarify your options.
Is naltrexone addictive?
No. Naltrexone is an opioid antagonist — it blocks opioid receptors rather than activating them. This makes it fundamentally different from medications like benzodiazepines or opioids, which do carry addiction risk.
How much does medication for alcohol cost?
Generic oral naltrexone runs about $30–50/month at most pharmacies, often cheaper with GoodRx. Vivitrol (injectable naltrexone) is $1,000–1,500/month without insurance, but most insurance, including Medicaid, covers it. Telehealth platforms like Sunnyside Med charge a platform fee (starting at $99/mo for the medical program) on top of medication costs.
Can my regular doctor prescribe naltrexone?
Yes — any licensed physician or nurse practitioner can prescribe it. No special DEA waiver required (unlike buprenorphine for opioid use disorder). The challenge is that many primary care providers aren’t familiar with using it for alcohol use. You may need to bring it up yourself and mention that you’d like to explore it. If your doctor isn’t comfortable, telehealth platforms are a reliable alternative.
Should I combine medication with other treatments?
The research says yes. Medication handles the neurological piece — cravings, reward signaling. Tracking, coaching, and habit change handle the behavioral piece. Sunnyside is designed around this combination: a drink tracking app (from $8.25/mo, 15-day free trial) plus Sunnyside Med for naltrexone access and management.
