Until law, GLP-1 drugs were used to treat diabetes, obesity and even the recent evidences suggest that it could as well be used to treat chronic kidney problems. There is yet another research, published in JAMA Psychiatry on February 25, titled Once-Weekly Semaglutide in Adults With Alcohol Use Disorder: A Randomized Clinical Trial that explores if GLP-1 receptor agonist semaglutide reduce alcohol consumption and cravings in adults with alcohol use disorder.

What Do Studies Say?

The research was conducted over a period of 9 weeks, where in the randomized clinical trial, the participants who were administered semaglutide, it led to reductions in some but not all measures of weekly consumptions. It also reduced weekly alcohol and craving related to placebo, and also led to a greater relative reduction in cigarettes per day.

The research also found that weekly injections of semaglutide, which is the active ingredient in weight loss drugs like Wegovy also helped reduce cravings in people with alcohol use disorder.

The lead author Christian Hendershot said that these findings will help in developing new approaches to treat alcoholism. "Two drugs currently approved to reduce alcohol consumption aren't widely used. The popularity of Ozempic and other GLP-1 receptor agonists increases the chances of broad adoption of these treatments for alcohol use disorder," said Hendershot in news release by the University of Southern California's Institute for Addiction Research, where he is the director.

The study is government-funded research and was funded by the National Institute on Alcohol Abuse and Alcoholism, part of the National Institutes of Health.

How Was The Study Conducted?

The study was small, and took in account for only 48 adults over two months, thus experts say that it is not yet clear how safe these drugs are for people who do not need to lose weight. Though the results do add up with the evidence form animal studies on drugs like Ozempic and Wegovy on how it helps manage cravings, not just for food, but also for tobacco and alcohol. Scientists are also studying these drugs on smokers, people with opioid addiction and cocaine users.

Co-author Dr Klara Klein of the University of North Carolina at Chapel Hill who treats people with obesity and diabetes said, "This is such promising data. And we need more of it. We frequently will hear that once people start these medications that their desire to drink is very reduced, if not completely abolished."

Why Does It Work So Well Against Alcoholism?

The GLP-1 receptor agonists work by mimicking hormones GLP-1 in the gut and brain that regulates appetite and feelings of fullness. This response is what helps one lose weight, and what helps one curb their craving for alcohol. These drugs that mimic the functioning of your brain, which is responsible to tell your body when to stop consuming, are the same hormones that tell your body about other kinds of consumptions, including alcohol. Therefore by consuming the weight loss drugs one can treat alcohol use disorder.

However, the researchers have pointed out on the limited data on the research and have suggested to continue using the three approved drugs by the National Institute on Alcohol Abuse and Alcoholism and Substance Abuse and Mental Health Services Administration, namely, Disulfiram, Naltrexone, and Acamprosate to treat alcohol use disorder until large studies confirm these findings.

GLP-1 drugs such as Ozempic and Wegovy can reduce cardiovascular events and deaths in people with type 2 diabetes (T2D) and some people with obesity. However, stopping treatment may affect these benefits.

Around 20–50% of patients discontinue GLP-1 therapy within the first year. Previous studies have linked discontinuation to weight regain and worsening blood sugar, blood pressure and cholesterol levels.

Now, a study published in The Lancet Regional Health has found that people with type 2 diabetes and no previous cardiovascular disease who stopped GLP-1 treatment had nearly twice the risk of heart attack, stroke or death from any cause compared with those who continued.

"In people with T2D and without previous cardiovascular disease, interrupting a therapy with GLP-1RA was associated with a higher risk of a composite of myocardial infarction, stroke, or death from any cause compared to those continuing the treatment," said researchers from IRCCS MultiMedica in Milan, Italy.

However, the observational study cannot establish that stopping GLP-1 drugs directly caused the increased risk. Researchers also did not know why patients discontinued treatment, which could have been due to side effects, cost or underlying illnesses such as frailty or cancer.

What Did The Study Find?

Researchers analysed electronic medical records from more than 300 diabetes clinics in the Italian Association of Clinical Diabetologists (AMD) database, covering 2004–2024.

They identified more than 80,000 people with type 2 diabetes and no established cardiovascular disease who had started GLP-1 treatment.

Those who continued treatment took the medication for nearly three years on average, compared with just over one year among those who stopped.

The combined risk of non-fatal heart attack, non-fatal stroke or death from any cause was nearly twice as high among those who discontinued treatment.

• Those who stopped: About 4 events per 100 people per year.
• Those who continued: About 2 events per 100 people per year.

People With Obesity Had Higher Risks

Among those who discontinued treatment, the risks of adverse outcomes were higher in people with obesity (body mass index of 30 or above) than in those without obesity.

Interestingly, changes in weight, blood sugar and blood pressure after stopping treatment were modest and similar among those who subsequently experienced a heart attack, stroke or death and those who did not.

This suggests that changes in these risk factors may not fully explain the higher rates of adverse outcomes.

Should You Stop Ozempic Or Wegovy?

Lead author Antonio Ceriello, head of diabetes research at IRCCS MultiMedica, said the association between stopping GLP-1 receptor agonists and poorer cardiovascular outcomes was "not a complete surprise". However, he noted that the scale of the association was significant, ABC News reported.

The researchers said long-term GLP-1 use may be important for maintaining health benefits in people with type 2 diabetes, but further studies are needed to establish whether stopping treatment directly increases cardiovascular risk or reflects worsening underlying health.

People taking Ozempic, Wegovy or other GLP-1 medications should discuss any decision to stop treatment with their doctor.

Eli Lilly's oral weight-loss drug Foundayo, that received FDA approval in April 2026, has shown promise in reducing the severity of obstructive sleep apnoea (OSA) in a recent trial.

OSA is a condition in which breathing repeatedly gets interrupted during sleep. In a late-stage clinical trial, the medicine reduced the repeated starting and stopping of breathing by up to 44% over 52 weeks in adults with moderate-to-severe sleep apnoea and overweight or obesity.

The findings from the phase 3 ATTAIN-OSA clinical programme were presented at the American Heart Association's Scientific Sessions 2026 on November 9 and published simultaneously in JAMA. The study included 712 participants, divided into two groups based on whether they were using positive airway pressure (PAP) therapy.

Eli Lilly plans to submit the findings to the US Food and Drug Administration (FDA) by the end of 2026 to seek approval for Foundayo as a treatment for moderate-to-severe obstructive sleep apnoea in adults with overweight or obesity.

Foundayo Reduces Sleep Apnoea Episodes

The trial evaluated Foundayo, also known by its generic name orforglipron, in two separate studies. One involved 363 adults who were not using PAP therapy, while the other included 349 participants who continued using it.

After 52 weeks, the drug reduced the number of breathing interruptions per hour, measured using the apnoea-hypopnoea index (AHI).

The findings included:

• Participants not using PAP therapy: Breathing interruptions fell by 43.8% compared to a 6.3% reduction in the placebo group.
• Participants using PAP therapy: Breathing interruptions fell by 27.5% compared to a 3% reduction in the placebo group.
• Better oxygen levels: Sleep apnoea-related oxygen deprivation, measured through hypoxic burden, fell by 55.9% in the group not using PAP and 45.8% in the group using PAP.

The drug also helped some participants reach remission or mild disease. According to Lilly's reported efficacy analysis, this included 31.5% of participants not using PAP therapy and 19.6% of those using it.

Can Foundayo Replace CPAP Therapy?

Continuous positive airway pressure (CPAP), a form of PAP therapy, remains a standard treatment for obstructive sleep apnoea. It uses a machine to deliver a steady flow of air through a mask, keeping the airway open during sleep.

The ATTAIN-OSA programme included participants who were not using PAP therapy as well as those who continued using it. The results suggest that Foundayo could benefit both groups, but they do not establish that patients can stop using CPAP.

Vaishnavi Kundel, the study's presenting author and Associate Professor of Medicine at the Icahn School of Medicine at Mount Sinai, said, “If approved to treat obstructive sleep apnea, orforglipron could be a promising oral pharmacologic option for people with overweight or obesity and this condition. A convenient daily pill may help expand access to treatment for sleep apnea, and it could potentially be used with CPAP or other therapies to better meet individual patient’s needs.”

More About Foundayo

Foundayo is an oral glucagon-like peptide-1 (GLP-1) receptor agonist. It is taken once daily and works by mimicking the GLP-1 hormone, which helps regulate appetite, calorie intake and blood glucose levels.

By reducing appetite and supporting weight loss, the drug may help address one of the important risk factors of obstructive sleep apnoea.

Excess weight, especially around the neck and upper airway, can increase the likelihood of airway narrowing or collapse during sleep. When the airway repeatedly becomes blocked, breathing interruptions occur and blood oxygen levels can fall.

Participants taking Foundayo lost an average of 11.5% of their body weight in the study group not using PAP therapy and 11.2% in the group using it.

Why Is Obstructive Sleep Apnoea A Concern?

Obstructive sleep apnoea is a breathing disorder related to sleep in which the muscles and soft tissues of the upper airway relax during sleep, causing the airway to narrow or become temporarily blocked.

This results in repeated pauses in breathing or episodes of shallow breathing, disrupting sleep and reducing oxygen levels. Common symptoms include:

• Loud and constant snoring
• Episodes of gasping or choking during sleep
• Waking up frequently during the night
• Morning headaches
• Excessive daytime sleepiness
• Difficulty concentrating and irritability

Amid increasing reports of a rare form of sudden vision loss called nonarteritic anterior ischemic optic neuropathy (NAION) following the use of drugs such as Ozempic, Wegovy and Mounjaro, the U.S. Food and Drug Administration (FDA) has ordered GLP-1 drugmakers Novo Nordisk and Eli Lilly to add warnings about the potential eye risk to their drug labels.

NAION can cause sudden, painless vision loss in one eye and, in some cases, permanent impairment.

In a Drug Safety Communication, the FDA informed patients and healthcare providers about the potential increased risk associated with these medicines. It is requiring manufacturers to include information about NAION in the Warnings and Precautions section of their drug labels.

The agency said it evaluated clinical trial data, animal studies and post-marketing evidence, including observational studies and case reports.

GLP-1 Users File Lawsuits Over Vision Loss

The FDA action comes amid lawsuits filed by people who allege they developed NAION after taking GLP-1 drugs such as Ozempic and Wegovy.

According to The Wall Street Journal, US law firm Weitz & Luxenberg has filed more than 90 lawsuits in New Jersey state court since 2025 on behalf of people who say they developed the condition while taking these medicines.

Separate federal lawsuits in Philadelphia accuse Novo Nordisk and Eli Lilly of failing to provide adequate warnings about the potential eye risk. The cases are pending. The allegations do not establish that the medicines caused the condition.

Regulators in Europe and Australia have also required warnings about a possible increased risk of NAION with some GLP-1 medicines.

In the US, vision problems are listed as possible side effects, but NAION had not previously been included as a specific risk in FDA-required labelling. The FDA's Sentinel Initiative is also reviewing the possible safety signal.

What Is NAION?

NAION is the most common acute optic neuropathy in people over 50, according to the Mayo Clinic. It occurs when blood flow to the optic nerve is reduced, damaging the nerve that carries visual information from the eye to the brain.

The condition typically causes sudden, painless vision loss in one eye. While some patients may experience partial improvement, the damage can be permanent. There is currently no proven treatment to reverse the vision loss.

Diabetes itself increases the risk of NAION, independent of GLP-1 use. Other risk factors include low blood pressure during sleep and having a small optic nerve cup.

What Does Research Say About The Risk?

The potential association between GLP-1 medicines and NAION has been under regulatory review internationally.

Last year, the European Medicines Agency's safety committee said NAION may affect up to one in 10,000 people taking semaglutide for at least one year. Semaglutide is the active ingredient in Ozempic, Wegovy and Rybelsus.

The Danish Patient Compensation Association also granted compensation to four patients who experienced vision loss after using Novo Nordisk's GLP-1 medicines.

A large study published in 2025 tracked nearly 175,000 people with diabetes taking semaglutide and an equal number taking non-GLP-1 medicines. It found that the risk of NAION was more than twice as high after two years of treatment with semaglutide compared with other diabetes medicines.

However, an observed association does not establish that the medicines directly caused the condition.

The FDA routinely monitors medicines after they enter the market, evaluates potential safety signals and takes regulatory action when appropriate.
