Since weight-loss drugs that concentrate on the hormone GLP-1 have surged in reputation, some additional health benefits have emerged. Past serving to individuals shed kilos, additionally they lower the risk of heart disease and sleep apnea—and the U.S. Meals and Drug Administration has acknowledged these advantages by approving adjustments to the medication’ labels.
Now, one kind of weight-loss remedy is proving useful with one other well being challenge. In a study printed Feb. 12 in JAMA Psychiatry, researchers report that semaglutide, higher referred to as Ozempic or Wegovy, helped individuals with alcohol dependancy cut back their craving and drink much less.
The trial concerned 48 individuals with alcohol-use dysfunction, which for males means consuming greater than 14 drinks per week, with two or extra heavy-drinking occasions throughout the week; for ladies, it means consuming greater than seven drinks weekly with two or extra of those ingesting episodes. Nobody within the examine was receiving remedy for his or her ingesting, and most had been chubby or overweight.
Researchers divided individuals into two teams and in contrast weekly injections of semaglutide to placebo, whereas monitoring variations within the quantity of alcohol individuals drank and the way typically they drank over 2.5 months. The examine was uniquely constructed: Contributors got here right into a lab designed to seem like a lounge, the place they might calm down, watch TV, and drink as a lot of their favourite alcoholic drinks as they desired for about two hours. The researchers recorded how a lot they drank initially of the examine—earlier than they obtained any remedy or placebo—after which once more on the finish of the examine. In between, members got here in for weekly visits to obtain their injections and reply detailed questions on their alcohol consumption over the earlier week.

Whereas individuals taking the drug did not drink any fewer variety of days than individuals within the management group, they did drink much less alcohol on the finish of the examine, says Christian Hendershot, professor of inhabitants and public well being science and director of scientific analysis on the USC Institute for Habit Science, and the lead researcher of the examine. This implies that the rewarding and addictive enchantment of alcohol may need been diminished for them—much like the best way meals is much less attractive for these taking semaglutide for weight reduction. “These drugs don’t make individuals cease consuming altogether, however cut back the urge to eat so there’s urge for food discount and satiety,” he says. “I believe that is very a lot analogous.”
Hendershot says he anticipated to see an impact of semaglutide on alcohol-use dysfunction, however to not this extent. Medication like semaglutide have an effect on the GLP-1 hormone, which works on the reward and satiety areas of the mind. Previous studies, principally in animals, confirmed that these medication might dampen dependancy and cravings for substances together with alcohol. Non-scientific, anecdotal reviews from individuals taking semaglutide to deal with diabetes or for weight reduction additionally recommended that the drugs curbed the need to drink.
“The magnitude of the impact, particularly at these doses, was considerably stunning,” Hendershot says. Individuals within the examine obtain the 2 lowest doses of semaglutide; the dose used for weight reduction is about 4 fold increased.

The discount in craving that folks reported, and the discount within the quantity they drank within the living-room lab initially of the examine vs. the tip, is much like the impact of current prescription therapies for alcohol-use dysfunction, resembling naltrexone, Hendershot says. However whereas the FDA has accepted three such therapies, they’re “underutilized” for causes together with stigma and a lack of expertise, he says.
That’s the place GLP-1 drugs might have a bonus, since they’re broadly widespread and acquainted to many individuals in each the general public and within the medical neighborhood. However whereas his small examine is encouraging, Hendershot says it’s too early to make use of GLP-1 medication off label to deal with alcohol-use dysfunction. “We all know individuals are prescribing GLP-1 receptor agonists off label for this function, but it surely’s greatest to suggest as an alternative that they use FDA-approved therapies which might be already obtainable,” he says. “We actually would want a handful of bigger scientific trials to deal with that query, and we’re nonetheless fairly far out from that degree of conclusiveness.”
Extra questions stay about the perfect dose of those drugs to probably deal with alcohol dependancy, in addition to whether or not medication that concentrate on a number of weight-loss-related hormones—like tirzepatide, bought as Mounjaro and Zepbound—might have even higher outcomes. Hendershot’s workforce is researching these questions.
“Proper now, this knowledge factors to a reasonably constant image throughout animal research, and now early human findings, of GLP-1’s impact on alcohol-use dysfunction,” he says. “The following activity is to generate extra human knowledge from bigger scientific trials.”
