✓ VERIFIED — Randomized Trial Evidence Confirms Effect
JAMA Psychiatry, April 2025
The Viral Claim
For years, people on GLP-1 medications have reported an unexpected side effect: their desire to drink alcohol just... disappeared. Reddit threads, TikTok videos, and news articles have documented countless anecdotes of people who say they simply stopped wanting alcohol after starting Ozempic or Wegovy.
But anecdotes aren't evidence. Was this real, or placebo effect?
The Evidence: JAMA Psychiatry Study
In April 2025, researchers published the first landmark randomized controlled trial in JAMA Psychiatry confirming what users had been saying: semaglutide significantly reduces alcohol consumption in people with alcohol use disorder.
This wasn't a small observational study. It was a properly designed clinical trial led by Christian Hendershot, PhD, a psychologist now at the University of Southern California, demonstrating that GLP-1 drugs can alter addictive behavior in people with a diagnosed substance-use disorder.
Supporting Evidence: The Swedish Registry Study
Earlier research from Sweden had already suggested a connection. A large population study using Swedish health registries found that people taking GLP-1 medications for obesity had lower rates of alcohol-related hospitalizations compared to those taking other obesity medications.

Why Does This Happen?
Scientists have mapped out why GLP-1 drugs reduce both food cravings AND alcohol cravings—they work on the same brain pathways:
🧠 The Neuroscience
- GLP-1 receptors in reward circuits: GLP-1 receptors sit on neurons throughout the brain's reward network. When activated, they reduce dopamine signaling—making rewarding experiences (food, alcohol, drugs) feel less compelling.
- Dampened dopamine response: When semaglutide mimics GLP-1, it blunts the dopamine surge that normally accompanies alcohol. The "reward" from drinking becomes less intense.
- Reduced stress response: GLP-1 activation in the amygdala mutes stress hormones associated with anxiety and craving—key triggers for drinking.
- Dual action: This combination—calming both the urge AND the stress that triggers the urge—may explain reduced relapse rates in animal studies.
"GLP-1 therapies help to blunt urges for alcohol, opioids, nicotine and cocaine through some of the same brain pathways that also quell hunger cues and overeating."— Nature, December 2025
What Users Report
Anecdotal reports consistently describe similar experiences:
- "I just forgot to drink" — Many users say alcohol simply stops occurring to them as an option
- "One drink is enough now" — Previously heavy drinkers report feeling satisfied after one drink
- "Alcohol tastes different" — Some report that alcohol doesn't taste as good or appealing
- "No urge at social events" — People who relied on "liquid courage" say the social anxiety driving drinking also decreased
- "Morning cravings gone" — Those with alcohol dependence report the physical pull toward drinking disappeared
Important Caveats
Before you ask your doctor for Ozempic to quit drinking, know this:
- Not FDA-approved for alcohol use disorder: Semaglutide is only approved for diabetes (Ozempic) and obesity (Wegovy). Using it for alcohol reduction is off-label.
- Not a replacement for addiction treatment: GLP-1 drugs may be a tool, not a cure. Comprehensive treatment addresses psychological, social, and physical factors.
- More research needed: While the JAMA trial is significant, larger Phase III trials would be needed for FDA approval for this indication.
- Side effects still apply: GI side effects, potential muscle loss, and other risks of GLP-1 drugs remain relevant.
Where Research Is Heading
More than a dozen randomized clinical trials testing GLP-1 drugs for addiction are now underway worldwide, including studies for:
- Alcohol use disorder — Multiple trials in progress
- Opioid use disorder — Penn State Phase II trial underway (read more)
- Nicotine/smoking cessation — Clinical trials ongoing
- Cocaine use — Preclinical evidence strong; human trials planned
Eli Lilly CEO Dave Ricks indicated at the 2025 JP Morgan healthcare conference that the company plans to study tirzepatide (Mounjaro/Zepbound) for "a number of dependencies—alcohol, tobacco seems pretty straightforward."
The Bottom Line
The claim that Ozempic reduces alcohol cravings is verified. A randomized controlled trial published in JAMA Psychiatry showed semaglutide significantly reduces alcohol consumption in people with alcohol use disorder. The mechanism—dampened dopamine response and reduced stress signaling—explains both food and alcohol craving reduction.
If you're struggling with alcohol use and considering GLP-1 medications, talk to your healthcare provider. These drugs are not approved for alcohol treatment, but the emerging evidence is promising enough that some physicians may discuss off-label use in appropriate cases.
For those already on GLP-1s for weight loss or diabetes who notice reduced alcohol interest: you're not imagining it. The science confirms what you're experiencing.
