If you’re considering naltrexone for cutting back on drinking, you’re not overreacting. Naltrexone was designed for people who want to drink less, not just people who need to stop. And the science increasingly supports using it before things get serious.

Many people who want to cut back on drinking don’t think of themselves as having an “alcohol problem” in the traditional sense. They may be successful at work, keep up with family responsibilities, and rarely experience obvious consequences from drinking. They simply find themselves drinking more often or more heavily than they intend to.

That’s where naltrexone may help. Naltrexone is a prescription medication that reduces alcohol’s rewarding effects, making it easier for many people to cut back. You don’t have to wait until your drinking becomes severe before talking with a healthcare provider about whether medication is appropriate. If alcohol is no longer fitting the life you want to live, it’s reasonable to explore evidence-based tools like Sunnyside Med that can help you change your habits.

The Binary That’s Keeping You Stuck

Conversations about alcohol often fall into two extremes: either your drinking is completely normal, or it’s severe enough to require treatment. That leaves little room for the many people who want to change their drinking habits but don’t really identify with either category.

In reality, alcohol use exists on a spectrum. According to the National Institute on Alcohol Abuse and Alcoholism, an estimated 28 million U.S. adults meet the diagnostic criteria for alcohol use disorder, ranging from mild to severe. Many others don’t meet the criteria for alcohol use disorder but still drink more than they’d like or experience alcohol-related health consequences.

Many people within this “gray area” delay taking action that could meaningfully improve their lives. Research suggests it often takes years between recognizing a problem and seeking treatment, even as drinking habits become increasingly problematic.

You don’t have to wait until your drinking becomes severe to explore evidence-based support. If your goal is cutting back, medications like naltrexone are often most effective when paired with behavioral support. That’s why Sunnyside Med combines prescription treatment with evidence-based habit change tools designed to help you build lasting routines.

How Naltrexone Works for Cutting Back

Naltrexone works by blocking opioid receptors in the brain, reducing the pleasurable and rewarding effects of alcohol. Many people experience fewer cravings, less preoccupation with drinking, and greater control over when to stop.

Rather than making you rely on willpower alone, the medication impacts the biology that drives the urge to keep drinking. For many people, the internal debate over whether to have another drink slows significantly, making it easier to stop after one or two instead of continuing out of habit.

As one Sunnyside Med member put it: “For the first time in a long time, I don’t feel that constant pull to reach for a glass of wine. The urge that used to feel automatic just isn’t there.”

Clinical trials have consistently found that naltrexone reduces heavy drinking days and lowers the risk of returning to heavy drinking, making it one of the best-studied medications for people whose goal is moderation rather than abstinence. Dr. Glenn-Milo Santos of UCSF Health offers a simple way to think about how the medication feels in practice: “Naltrexone is like an appetite suppressant for alcohol.”

Importantly, naltrexone does not make you sick if you drink, and it does not require abstinence to be effective. Many people use it specifically to reduce heavy drinking and build healthier habits around alcohol rather than to quit completely.

The Research on Naltrexone and Non-Dependent Drinkers

Naltrexone is one of the most extensively studied medications for alcohol use disorder (AUD). Large systematic reviews—including a 2023 review published in JAMA—have consistently found that oral naltrexone reduces heavy drinking and lowers the risk of returning to heavy drinking, making it a first-line treatment in many clinical guidelines (McPheeters et al., 2023).

Most of that research has focused on people with moderate to severe alcohol use disorder, where the evidence is strongest. More recently, however, researchers have begun studying whether naltrexone can also help people whose goal is simply to drink less.

The results are encouraging. In a placebo-controlled trial of 128 young adults who regularly drank heavily but did not meet criteria for alcohol dependence, low-dose naltrexone reduced the frequency of heavy drinking episodes (O’Malley et al., 2015). A separate randomized controlled trial found that targeted naltrexone—taken only before anticipated drinking occasions—significantly reduced drinks per drinking day among adults with mild to moderate alcohol use disorder (Santos et al., 2022).

Other research suggests naltrexone may be especially helpful for people who drink primarily for reward or pleasure. In one study, participants with stronger “reward-driven” drinking patterns experienced greater reductions in drinking urges while taking naltrexone (Roos et al., 2021). Earlier research also found dose-dependent reductions in hazardous drinking among people who were not actively seeking alcohol treatment, suggesting the medication may help people reduce their drinking before it becomes more severe (O’Malley et al., 2009).

Taken together, these findings suggest that naltrexone’s benefits may extend beyond people with severe alcohol use disorder. While the evidence for moderation-focused and non-dependent drinkers is still growing, it supports the idea that medication can be a valuable tool for people who want to cut back before their drinking progresses.

A Sunnyside Co-Founder’s Naltrexone Experience

One reason Sunnyside Med focuses on moderation—not just abstinence—is because its co-founder, Ian Andersen, had a goal that many members share: he wanted to cut back on drinking, not necessarily stop altogether. He wasn’t in crisis, but he found that once he started drinking, it was difficult to stop where he intended.

“I just knew I was drinking more than I wanted to,” he said. “That gap, between what you want and what you actually do, that’s where so many people are stuck. We built Sunnyside Med for them.”

After starting naltrexone, Ian noticed a shift that many people describe when the medication is working.

“The alcohol noise went quiet almost immediately. I stopped thinking about drinking so much and started thinking about everything else more,” he said.

While every person’s experience is different, Ian’s story reflects why many people explore naltrexone for cutting back. Rather than waiting until drinking caused serious consequences, he chose to use an evidence-based tool to help change a pattern that no longer matched his goals.

Is Naltrexone Right for Your Mindful Drinking Journey?

Naltrexone isn’t the right choice for everyone, but it may be worth discussing with a healthcare provider if your goal is to cut back on drinking rather than quit completely.

A few questions can help you decide whether it’s worth exploring:

• Do you regularly drink more than you intend to?
• Have you tried to cut back but found it harder than expected?
• Are you concerned about where your drinking habits are headed, even if they haven’t caused major problems?

If you answered yes to any of those questions, it may be worth learning more about naltrexone.

One common misconception is that you have to “drink enough” before medication becomes appropriate. In reality, there isn’t a universal threshold based on the number of drinks you have each week. Instead, clinicians consider your goals, your medical history, and whether naltrexone is safe for you to take. 

Because naltrexone blocks opioid receptors, it isn’t appropriate for people currently using opioid medications. Certain liver conditions may also require an alternative approach.

What Naltrexone for Cutting Back Actually Looks (And Feels) Like

Naltrexone doesn’t change your drinking overnight. For most people, the changes are gradual. During the first week or two, it’s common to experience mild side effects such as nausea or fatigue while your body adjusts. These symptoms usually improve within a couple of weeks.

As treatment continues, many people notice something different: Drinking requires less mental effort to control. The urge to keep going after the first drink becomes less persistent, and stopping at one or two drinks starts to feel more natural.

Here are some real testimonials from Sunnyside Med members:

• “Went to dinner with family last night… live music at a bar first… I had three drinks the entire night. This naltrexone stuff is amazing.”
• “I had a cocktail last night and for the first time ever, I didn’t drink the whole thing. In fact, I dumped half of it down the drain.”
• “I wasn’t someone who drank heavily, but I was someone who couldn’t have ‘just one drink.’ I’m proud to say that I am now.”

Medication is only one part of the process, though. The landmark COMBINE study, for example, found that outcomes improved when naltrexone was paired with behavioral support rather than used on its own. That’s why Sunnyside Med combines clinician-prescribed naltrexone with evidence-based behavior change tools designed to help members build lasting routines. These include:

• Daily reminders: Get daily nudges to stay up to date with your medication, with personalized reminders about goals and progress.
• Coaching: Text with a real human coach when you need extra support, 7 days a week. Our peer coaches have been on the journey too.
• Community: Give and get support in the vibrant Sunnyside community, a place to cultivate a positive mindset every day.
• Progress: Whether it’s sleep, dry days, or drinks cut, Sunnyside shows your progress as it matters most to you.

Can I take naltrexone just to cut back on drinking, not quit?

Yes. Naltrexone has been studied alongside moderation-based goals, not just abstinence. Your goal can simply be less.

Do I drink enough to qualify for naltrexone?

There’s no minimum number of drinks that makes you “eligible.” If your drinking concerns you and you want to change, that’s enough of a reason to explore your options. A clinician can help determine if naltrexone is right for you.

Is naltrexone safe for someone who doesn’t drink that much?

Naltrexone has been FDA-approved since 1994 and studied extensively in clinical trials. The main contraindications are opioid medications and certain liver conditions, not the amount you drink. A clinician will review your health history before prescribing.
