Can I drink alcohol while taking Wegovy?

Moderate alcohol is generally acceptable, but keep it sensible while you settle into treatment. Alcohol can irritate the stomach and may worsen nausea or reflux during dose increases. If you have diabetes or take medicines that can lower blood sugar, be extra cautious with alcohol and discuss safe limits with your team.

Why alcohol and Wegovy can interact

Wegovy (semaglutide) works by slowing how quickly food leaves the stomach, which is part of why people often feel fuller for longer. Alcohol, on the other hand, can irritate the stomach lining and make reflux or nausea worse. Combining the two, especially early in treatment or when the dose is being raised, can increase the chances of feeling uncomfortable. Some people find that a small glass of wine or beer feels different on Wegovy compared with before, simply because digestion is slowed and the body responds more strongly.

Considering diabetes and blood sugar

For people with type 2 diabetes, alcohol brings another layer of complexity. Both alcohol and medicines like insulin or sulfonylureas can lower blood sugar. Adding Wegovy to the mix may affect how the body balances these changes. NICE guidance advises that people using semaglutide should monitor blood glucose carefully if they drink, as delayed stomach emptying can alter how quickly food and alcohol are absorbed. In practice this means a risk of unexpected dips hours after drinking, especially with spirits or wine on an empty stomach. Discussing individual safe limits with your diabetes team is always a good step, as they can help prevent unpredictable lows or swings.

Moderation and practical choices

The UK Chief Medical Officers’ guidelines suggest keeping alcohol intake within 14 units per week, spread over several days, with at least a couple of alcohol-free days. For someone taking Wegovy, moderation is even more important because the medicine already changes digestion and appetite. Choosing lower-strength drinks, drinking slowly, and having food alongside alcohol may reduce the chances of reflux or discomfort. Many people find they naturally drink less once on treatment, partly because the social cues around food and drink shift when appetite is lower. Alcohol is also energy-dense, so keeping intake modest helps protect the overall progress made with weight loss.

What NHS advice highlights

The NHS makes it clear that alcohol can interact with both medicines and health conditions. In the case of Wegovy, while there is no strict ban, NHS clinicians often emphasise caution during the first few months of use. This is when side effects like nausea and diarrhoea are most common, and alcohol can make them worse. Being mindful of timing also helps — spacing drinks away from your injection day or avoiding alcohol if you are already feeling queasy can make the adjustment period smoother. NHS weight management services also point out that alcohol contains “empty calories” with little nutritional value, so frequent drinking can undermine lifestyle changes that go hand in hand with treatment.

The role of personal tolerance

Everyone responds differently, and part of living with Wegovy is learning how your body reacts in real situations. Some people find that one or two drinks cause no issue, while others experience more reflux than before. Keeping a simple note of when you drink, what you drank, and how you felt afterwards can be a useful way to spot patterns. If you notice that alcohol consistently worsens nausea, unsettles your sleep, or slows down your progress with weight, it may be worth cutting back further. Your GP, pharmacist, or specialist nurse can help weigh up whether alcohol is a good fit for you at this stage of treatment.

Looking at longer-term health

Beyond short-term side effects, it’s also worth considering the longer view. Alcohol can increase the risk of high blood pressure, liver strain, and certain cancers, all of which are already concerns in people living with overweight or related conditions. Large trials like SELECT have shown that Wegovy can improve heart health in people with established cardiovascular disease, but alcohol in excess may work against these gains. Balancing sensible drinking with the positive effects of treatment helps ensure the benefits are not diluted. For many people, reducing alcohol becomes part of the same lifestyle reset that Wegovy supports.

Social life and small adjustments

Questions about alcohol are often really about social life. People want to know if they can still join friends for a pint or enjoy a glass of wine at dinner. The good news is that in moderation, most people on Wegovy can still do these things. It may just mean smaller portions, spacing drinks more carefully, or choosing non-alcoholic alternatives when side effects are more noticeable. Many people find that friends and family are supportive once they explain they are focusing on health goals, and pubs and restaurants now offer far more low-alcohol and alcohol-free options than before.

The bigger picture

Alcohol and Wegovy do not have a dangerous direct clash, but combining them can add extra strain during an adjustment period. The real concern lies in stomach comfort, blood sugar control, and how alcohol fits into a longer-term plan for health. Sticking within the UK’s safe drinking guidelines and paying attention to your own tolerance makes it easier to keep treatment on track. In the end, moderation and self-awareness are what matter most, supported by open conversations with your care team.
