What is the effect of Ozempic combined with alcohol use?
Semaglutide reduces alcohol cravings and the number of heavy drinking episodes in people with an alcohol use disorder. It is not an officially approved treatment for alcohol problems, but discuss it with your doctor if you are using semaglutide and have questions about your alcohol use.
Semaglutide significantly reduces alcohol cravings and the number of heavy drinking episodes in randomised trials. In a smaller 9-week trial (48 participants), weekly cravings and the number of heavy drinking episodes fell significantly, but the total number of drinking days or average drinks per day did not change. A larger 26-week trial (108 participants) showed that heavy drinking episodes dropped by 41.1 percentage points in the semaglutide group, compared with 26.4 percentage points in the placebo group. That difference of just over 13 percentage points was statistically convincing. Oral semaglutide also showed fewer heavy drinking episodes, fewer drinks per drinking day, and less daily craving in a separate small trial (50 participants).
The mechanism behind this effect most likely lies in how semaglutide acts on reward circuits in the brain. Animal research shows that the drug lowers the reward value of alcohol and reduces the motivation to drink. Exactly how this works in humans has not yet been fully clarified.
Regarding safety: in the trials, people in the semaglutide group experienced side effects more often than the placebo group. These were almost always temporary, mild to moderate gastrointestinal complaints such as nausea. No serious safety problems have been reported that are specifically linked to the combination of semaglutide and alcohol use, but this still requires investigation in larger groups.
Semaglutide also reduces the number of cigarettes per day in smokers. This was found as an incidental finding in a small subgroup of the alcohol trial and should be interpreted with caution. Observational research and case series support the picture that semaglutide reduces alcohol use, but that evidence is weaker: there was no random assignment of participants, and with a case series of only six patients, chance findings cannot be ruled out.
The strongest evidence comes from two randomised double-blind trials in people with an alcohol use disorder, the largest of which followed 108 participants over 26 weeks. A systematic review of earlier animal and human studies supports the direction of the effect. The studies are still relatively small and short in duration; long-term effects and safety with prolonged use have not yet been well mapped.
Does orforglipron, the weight-loss pill, work as well as Ozempic?
Orforglipron works well for blood sugar and weight, but in obesity it is probably less powerful than injectable Ozempic and causes side effects more often. If you want to avoid the injection pen it is a serious option, but discuss it with your doctor, because the direct comparison on weight loss is still missing.
Is retatrutide more effective than Ozempic?
Indirect comparisons suggest that retatrutide produces greater weight loss than semaglutide (Ozempic/Wegovy), but the drug has not yet been approved and no direct head-to-head trial exists. If you want to be treated now, semaglutide or tirzepatide are the available choices.
Do GLP-1 medications (such as Ozempic) help you age more healthily?
For people with cardiovascular disease, kidney disease, or fatty liver disease, GLP-1 medications offer proven benefits that are also relevant at older ages. As an anti-ageing intervention in healthy people, their use is not yet supported by evidence.
What are the side effects of metformin?
Metformin causes gastrointestinal complaints such as diarrhoea, nausea and vomiting in a substantial proportion of users. Discuss with your doctor whether the dose can be built up gradually, or consider an alternative if the complaints persist.
What are the effects if you take NAD every day?
Taking 600-900 mg of a NAD supplement per day raises your NAD levels and provides some benefit for endurance, but long-term safety has not yet been properly studied.
Does the combination of glycine and NAC (GlyNAC) help against aging?
GlyNAC shows promising results in a small human study on oxidative stress, muscle function and inflammation, but the evidence is still too preliminary for strong recommendations.
