Since weight-loss medication that concentrate on the hormone GLP-1 have surged in recognition, some extra well being advantages have emerged. Past serving to folks shed kilos, additionally they decrease the chance of coronary heart illness and sleep apnea—and the U.S. Meals and Drug Administration has acknowledged these advantages by approving modifications to the medication’ labels.
Now, one kind of weight-loss remedy is proving useful with one other well being concern. In a examine printed Feb. 12 in JAMA Psychiatry, researchers report that semaglutide, higher often called Ozempic or Wegovy, helped folks with alcohol dependancy scale back their craving and drink much less.
The trial concerned 48 folks with alcohol-use dysfunction, which for males means consuming greater than 14 drinks every week, with two or extra heavy-drinking occasions in the course of the week; for ladies, it means consuming greater than seven drinks weekly with two or extra of those consuming episodes. Nobody within the examine was receiving remedy for his or her consuming, and most have been chubby or overweight.
Researchers divided folks into two teams and in contrast weekly injections of semaglutide to placebo, whereas monitoring variations within the quantity of alcohol folks 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 chill out, 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 in the beginning of the examine—earlier than they obtained any remedy or placebo—after which once more on the finish of the examine. In between, contributors got here in for weekly visits to obtain their injections and reply detailed questions on their alcohol consumption over the earlier week.

Whereas folks taking the drug did not drink any fewer variety of days than folks 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 means that the rewarding and addictive attraction of alcohol may need been diminished for them—much like the best way meals is much less engaging for these taking semaglutide for weight reduction. “These medicines don’t make folks cease consuming altogether, however scale back the urge to eat so there’s urge for food discount and satiety,” he says. “I feel 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. Medicine like semaglutide have an effect on the GLP-1 hormone, which works on the reward and satiety areas of the mind. Earlier research, largely in animals, confirmed that these medication might dampen dependancy and cravings for substances together with alcohol. Non-scientific, anecdotal reviews from folks taking semaglutide to deal with diabetes or for weight reduction additionally prompt that the medicines curbed the need to drink.
“The magnitude of the impact, particularly at these doses, was considerably shocking,” Hendershot says. Individuals within the examine obtain the 2 lowest doses of semaglutide; the dose used for weight reduction is about 4 fold greater.

The discount in craving that individuals reported, and the discount within the quantity they drank within the living-room lab in the beginning of the examine vs. the top, is much like the impact of present prescription remedies for alcohol-use dysfunction, corresponding to naltrexone, Hendershot says. However whereas the FDA has authorized three such remedies, they’re “underutilized” for causes together with stigma and a lack of knowledge, he says.
That’s the place GLP-1 medicines might have a bonus, since they’re broadly common and acquainted to many individuals in each the general public and within the medical group. 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 persons are prescribing GLP-1 receptor agonists off label for this goal, nevertheless it’s greatest to suggest as an alternative that they use FDA-approved remedies which can be already out there,” he says. “We actually would want a handful of bigger scientific trials to handle that query, and we’re nonetheless fairly far out from that stage of conclusiveness.”
Extra questions stay about one of the best dose of those medicines to doubtlessly 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 crew is researching these questions.
“Proper now, this information 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 job is to generate extra human information from bigger scientific trials.”
