Is there medicine you can take to stop drinking?

Yes — there are prescription medicines for drinking, and asking about them is an ordinary medical question, not a confession.

If you've gotten as far as typing this question, you've probably already tried the free advice: drink less, take a break, use more willpower. So here's the direct answer up front. The FDA has approved three medications for alcohol use disorder — naltrexone, acamprosate, and disulfiram — and any licensed clinician can prescribe them, not just an addiction specialist. These medicines have been around for decades; the surprise, for most people, is hearing that they exist at all.

What are the three medications?

Each one works in a genuinely different way, and knowing the differences is most of what you need for a useful conversation about them.

Naltrexone works on the reward side of a drink. Alcohol leans on the brain's opioid receptors — part of the wiring that makes a drink feel warm, loose, and worth repeating — and naltrexone blocks those receptors, so the drink lands with less of a lift. It's FDA-approved for the treatment of alcohol dependence, taken as a tablet, and SAMHSA describes it as reducing cravings and the amount people drink. The hard rule attached to it: it blocks opioid painkillers too, so it's off the table for anyone taking or dependent on opioids.

Acamprosate leaves the reward alone and works on the aftermath instead. Long stretches of heavy drinking tilt the balance between the brain's main "go" chemical (glutamate) and its "calm down" side; take the alcohol away and the go side stays over-revved for a while, which is part of why early sobriety can feel so restless and wired. The pharmacology literature describes acamprosate as helping that over-revved system settle back toward normal, and it's FDA-approved specifically for staying stopped after you've already quit — not for cutting down while still drinking. One practical detail: it leaves the body through the kidneys rather than the liver, which is a reason it comes up for people whose liver has already taken a beating.

Disulfiram doesn't touch craving or reward at all. It blocks the step where your body clears acetaldehyde, the toxic middle product of alcohol digestion — so if you drink while taking it, acetaldehyde piles up and you feel promptly, memorably sick: flushing, pounding heart, nausea. It's a tripwire, useful for people who want a hard physical barrier between themselves and a drink. Its own FDA label frames it as an aid for people who want to stay in "enforced sobriety," and states plainly that it is not a cure.

For more depth on each, see naltrexone, acamprosate (Campral), and disulfiram (Antabuse).

Do they actually work?

Two of the three have solid evidence behind them, and none is a magic switch. When the Agency for Healthcare Research and Quality reviewed the trials in 2023, it found moderate-strength evidence that oral naltrexone and acamprosate each reduce a return to drinking. For disulfiram, the evidence against placebo came up inadequate — which isn't proof it fails, just that a deterrent pill is nearly impossible to test in a blinded trial, so the studies can't settle it.

There's a second consistent finding worth taking seriously: medication is meant to travel with support, not replace it. The American Academy of Family Physicians recommends pairing any of these medications with behavioral help — therapy, structured tracking, a support group, whatever form actually fits your life.

If these medicines are real, why haven't you heard of them?

Mostly because the conversation never happens. The same AAFP review notes that most people with alcohol use disorder are never offered medication — not because a clinician weighed their case and decided against it, but because nobody raised the option.

The scale of that gap is stark. In 2024, an estimated 27.9 million Americans ages 12 and older — about 9.7% of that age group — had past-year alcohol use disorder, per NIAAA. That same year, about 2.1 million of them received any alcohol-related treatment — roughly 7.6%.

Read that as an access-and-awareness problem, not a verdict on the medicines. If you're asking this question at all, you're already ahead of where most people ever get.

Why isn't willpower enough on its own?

Because sustained heavy drinking changes the terrain willpower has to operate on. Alcohol gets wired into reward, stress relief, sleep, and social ease, and the brain adapts around the constant input — which is why the private promises keep failing even when the rest of life still looks handled, why mornings get harder, and why the amount that used to feel like "enough" keeps drifting upward. At that point the question stops being whether you care enough. It becomes whether your brain and body have adapted in ways that make white-knuckling unreliable — and that's precisely the layer these medications work on. They don't supply motivation; they change what a drink, or a craving, does to you while you do the rest.

Do you have to quit completely before starting?

It depends on the medicine, and this is a real difference rather than fine print. Acamprosate is approved for people who have already stopped and want help staying stopped. Naltrexone shows up in a wider range of conversations, including with people whose goal is cutting back rather than zero, because what it does is blunt the payoff of a drink. Disulfiram only makes sense alongside an abstinence goal — the entire mechanism is what happens if you drink on it.

So before any appointment, get honest with yourself about the actual goal. "Fewer heavy nights," "no drinking before work," and "done entirely" point toward different conversations. A clinician can work with any of them; what they can't work with is a goal you won't say out loud.

How do you bring it up with a clinician?

Plainly. "I'm drinking more than I want to, and I'd like to talk about medication options" is a complete opening line. What makes the conversation productive is the information you bring:

• Your pattern: drinking days in a typical week, the range on heavier days, any morning drinking.
• Withdrawal history: shakes, sweats, or panic when you've stopped before — and especially any past seizures, confusion, or hallucinations.
• Other medications: everything, but opioid painkillers matter most, since they rule out naltrexone.
• Health history: liver and kidney health, pregnancy or plans for it, mental-health conditions.
• Your goal: even if the honest version is "I don't know yet."

If you don't have a doctor you'd want to have this conversation with, that gap is exactly what Clero is for: it connects you with a licensed clinician by telehealth who can review whether a medication like naltrexone fits your history and your goal.

When this is bigger than a medication question

One situation changes the order of operations. If stopping or sharply cutting back has ever given you severe shaking, confusion, hallucinations, or a seizure, the first conversation isn't about naltrexone or acamprosate — it's about how to stop safely, because MedlinePlus treats severe alcohol withdrawal as a medical emergency. If those symptoms are happening now, call 911 or go to an emergency room. And if any of this comes tangled with thoughts of harming yourself, call or text 988 first; that outranks everything else on this page.

For the planned, non-emergency version of that conversation, start with alcohol withdrawal symptoms and treatment options.

Two questions people ask next

Can a regular doctor prescribe these?

Yes. Primary-care clinicians can prescribe all three; no specialist referral is required. If yours has never brought it up, that's the awareness gap at work — you're allowed to raise it first.

Does asking about medication mean admitting you're an "alcoholic"?

No label is required at the door. The medication question is about a pattern and a goal: how much, how often, what happens when you try to stop, and what you want to change. Plenty of people who would never use that word about themselves have exactly the pattern these medicines were designed for.

This article is general education, not medical advice or a substitute for a clinician who knows your history. If you need help finding treatment and it's not an emergency, SAMHSA's National Helpline at 1-800-662-HELP offers confidential referrals; call or text 988 for thoughts of self-harm, and call 911 for seizures, confusion, or hallucinations after stopping drinking.
