Naltrexone for Alcohol: How This FDA-Approved Pill Reduces Cravings
📋 Medical Disclaimer: This article is for informational purposes only and does not constitute medical advice. Naltrexone is a prescription medication that should only be used under the supervision of a licensed healthcare provider. Always consult with a qualified medical professional before starting, stopping, or changing any medication or treatment plan. Individual responses to naltrexone vary, and the medication may not be appropriate for everyone, particularly those with liver conditions, those currently using opioids, or those who are pregnant or breastfeeding.
A New Chapter for an Old Medication
Key Takeaways:
Growing awareness of alcohol's health risks is driving renewed interest
Real-world success: One user reduced from 28 drinks/week to 7 drinks/week
For decades, a prescription medication has quietly helped people struggling with alcohol dependence. Now, naltrexone is stepping into the spotlight as growing awareness of alcohol's health risks prompts more people to seek help in moderating their drinking habits.
Caitlin Carlson, writing for National Geographic in December 2025, highlighted the story of Kate Carbonari, who began drinking at age 15 and by her early 60s was consuming approximately 28 drinks per week. After her doctor warned her about health risks and she began using naltrexone, she successfully reduced her consumption to a maximum of seven drinks per week while taking at least three full days off.

How Naltrexone Works in the Brain
Reduces cravings and makes drinking feel less rewarding
Does not prevent intoxication—only dampens the reward response
Naltrexone is an opioid antagonist that works by blocking opioid receptors in the brain. When someone consumes alcohol, it typically triggers the release of endogenous opioids—the body's natural feel-good chemicals that create the pleasurable buzz associated with drinking.
Dr. Sarah Wakeman, senior medical director for substance use disorder at Mass General Brigham, explained the mechanism to National Geographic: the medication binds to opioid receptors and blocks them, preventing anything from activating those receptors. This dampens the rewarding effects of alcohol and reduces cravings.
Dr. Glenn-Milo Santos, a professor at UCSF Community Health Systems, described it to National Geographic as essentially an appetite suppressant for alcohol. The medication makes drinking less enjoyable and reduces the reward associated with consumption, which tends to slow down both the rate and volume of drinking.
According to Dr. David Campbell, clinical director at Recover Together in Oregon, speaking to Fox News, naltrexone is particularly useful for people who experience strong cravings, frequently drink to excess once they start, or drink primarily for reward or relief rather than habit.
FDA Approval and Historical Context
The Sinclair Method (pairing drinking with naltrexone) dates back to the 1980s
Available as daily pill or monthly injection (approved 2006)
The medication was first approved by the FDA in 1984 to treat opioid dependence. A decade later, in 1994, it received approval for treating alcohol use disorder. The approach of using naltrexone to cut back on drinking dates back to the 1980s with what became known as the Sinclair Method, which pairs drinking with naltrexone to blunt alcohol's pleasurable effects.
In addition to the daily pill form, an injectable version was approved for alcohol use disorder in 2006 and for opioid use disorder in 2010, providing a once-monthly alternative for those who struggle with daily medication adherence.
An Underutilized Treatment
Growing interest among people who drink above recommended limits but don't have AUD
Often compared to "Ozempic for alcohol" due to similar appetite-suppressing concept
Despite its proven effectiveness, naltrexone remains significantly underutilized. Dr. Wakeman told National Geographic that only a single-digit percentage of people with alcohol use disorder currently take the medication. However, clinicians are beginning to see growing interest among people who regularly drink above recommended limits but don't meet the clinical criteria for alcohol use disorder.
The comparison to GLP-1 medications has helped increase public awareness. Some have dubbed naltrexone "the Ozempic for alcohol," a comparison Dr. Santos finds useful for public understanding. Like appetite suppressants for food, naltrexone suppresses the desire for alcohol.
Research Supporting Effectiveness
"As-needed" dosing (taking before drinking) also shows significant benefits
Benefits persisted 6 months after study completion in some research
Scientific evidence supports naltrexone's effectiveness. In 2022, Dr. Santos conducted a study examining whether the medication could help gay men who binge drink but don't have severe alcohol use disorder. The research found that naltrexone effectively helped participants reduce their drinking without requiring complete abstinence.
The study also tested an as-needed approach rather than daily dosing. Participants who took naltrexone in anticipation of drinking or when cravings hit experienced significant reductions in binge drinking days, overall drinks consumed during drinking days, and alcohol cravings. Notably, six months after the study, participants still showed lower rates of binge drinking compared to those who received a placebo.
Potential Side Effect and Considerations
Critical warning: Do NOT take with opioids—can cause severe withdrawal
Not recommended for: liver problems, pregnancy, breastfeeding, current opioid use
Like all medications, naltrexone can cause side effects, though many people tolerate it well. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), common side effects include nausea, headache, dizziness, fatigue, anxiety, and sleep disturbances. These effects are generally mild and often improve as the body adjusts.
Dr. Campbell emphasized to Fox News that the most critical consideration is ensuring there is no concurrent use of opioids, as taking naltrexone while using opioids can trigger precipitated withdrawal—a highly uncomfortable experience.
Certain groups should avoid naltrexone, including those with liver problems, individuals currently using opioids, and those who are pregnant or breastfeeding.
A Preventitive Approach to Alcohol Health
Key Takeaways:
Direct-to-consumer companies now offer naltrexone with behavioral support tools
People seeking help earlier as awareness grows about alcohol's effects on sleep, mood, and health
Dr. Santos described this approach to National Geographic as a paradigm shift that recognizes reducing heavy drinking before it progresses to severe alcohol use disorder is an important preventive step. This mindset has attracted companies like Sunnyside, which offers naltrexone along with behavioral tools to help people reduce drinking over time.
Nick Allen, Sunnyside co-founder and CEO, noted that as people become more aware of how alcohol affects sleep, mood, energy, and mental health, they're paying attention earlier and seeking support before things feel like a serious problem.
The Scope of Alcohol's Impact
By the Numbers (CDC Data):
~17% are classified as binge drinkers
~6% drink heavily
The potential reach of naltrexone is substantial. According to CDC data cited by Fox News, more than 50% of U.S. adults drink alcohol, approximately 17% are classified as binge drinkers, and about 6% drink heavily. Each year, around 178,000 deaths in the country are linked to excessive alcohol use.
Dr. Donita Robinson, a professor at the Bowles Center for Alcohol Studies at UNC School of Medicine, told Fox News that heavy alcohol consumption and binge drinking can lead to many health problems and worsen chronic conditions. Reducing intake can genuinely improve health outcomes.
What Experts Recommend
Ideally used in partnership with a trusted healthcare provider
Only available with prescription—avoid purchasing online without one
While naltrexone offers promise, experts emphasize it works best as part of a comprehensive approach. Dr. Robinson told Fox News that naltrexone is most effective when combined with counseling or other therapy. Jessica Steinman, chief clinical officer at No Matter What Recovery, described it to Fox News as an incredibly helpful tool for people struggling with alcohol use disorder, though she emphasized that moderation is not recommended for those with true dependence.
Dr. Wakeman noted to National Geographic that while direct-to-consumer access has expanded reach, in an ideal scenario, people would partner with a trusted doctor to address alcohol concerns holistically. Naltrexone is one tool among several available options.
The medication is available with a prescription from licensed healthcare providers. Health officials warn against purchasing it online without a prescription, as such products may be counterfeit and unsafe.
Looking Forward
As awareness grows about both alcohol's health impacts and available treatment options, naltrexone represents a shift in how society approaches drinking. Rather than the traditional all-or-nothing model, this medication offers a middle path for those who want to reduce their consumption without necessarily pursuing complete abstinence.
Dr. Wakeman summarized the situation to National Geographic: alcohol use is a health behavior, much like managing diabetes or other conditions. Effective tools exist to help people make meaningful changes in their relationship with alcohol.
