Wegovy and Alcohol: Can I Drink on the Medication?

Whether it’s an occasional drink with dinner or a toast at a wedding, alcohol can be a key part of our social lives. So if you’re taking Wegovy, you might be wondering: is it still okay to drink?

Understanding how alcohol might affect your body can keep you safe. It can also help you get the best results during your weight loss journey.

Here’s what you need to know about mixing Wegovy and alcohol – what happens and how it impacts side effects of Wegovy. We’ll also give you some tips on the safest way to enjoy the occasional glass.

Does Alcohol Interact with Wegovy?

Alcohol does not directly interact with semaglutide, the active ingredient in Wegovy. This means alcohol does not change the way the drug works in the body.

However, combining the two can still pose potential risks. Like other GLP-1 obesity management drugs, Wegovy works by slowing gastric emptying and reducing appetite. This can sometimes cause nausea or stomach discomfort. And these are side effects that alcohol may worsen.

Can You Drink Alcohol on Wegovy?

Yes, you can drink alcohol while taking Wegovy. But you should drink with caution – and in moderation.

Combining the two can increase the likelihood of side effects such as nausea, vomiting, or dizziness. This is especially likely in the early stages of treatment, when your body is still adjusting to the medication.

If you do drink, women should limit themselves to one drink per day. Men should not drink more than two. Avoid drinking on an empty stomach to reduce the risk of nausea and stomach irritation.

What Are the Risks of Mixing Alcohol and Wegovy?

Mixing alcohol and Wegovy can:

• Worsen Side Effects: Wegovy can cause stomach-related symptoms, such as nausea, vomiting, and stomach discomfort. Alcohol can irritate the stomach lining, increase acid production and cause nausea. Some patients report stronger Wegovy side effects with alcohol, such as vomiting.
• Cause Dehydration: Alcohol is a diuretic (it makes you pee more), which can contribute to dehydration. Vomiting and diarrhoea, side effects of both Wegovy and alcohol, can also cause you to lose fluids.
• Lower Your Blood Sugar: Alcohol can lower your blood sugar levels. Signs of low blood sugar include dizziness, confusion, sweating, and fainting.
• Impair Judgement Around Food: Alcohol can affect decision making around food. It may lead you to eat more than your body needs. This can make weight management harder.

Drinking affects each person differently. Occasional moderate drinking may be okay for some individuals. However, it’s important to pay attention to how your body reacts.

“You’re going to react differently to alcohol while on Wegovy, and that might change as you move up in dose,” explains Richard Wood, a pharmacist at Simple.

“So it’s important to be cautious. You might not be able to handle as much alcohol, and the negative effects of being drunk can hit harder and faster.”

For patients with type 2 diabetes, combining alcohol with Wegovy poses an additional risk. And when taken alongside diabetes medications, like insulin, this can increase the risk of low blood sugar. Consult your healthcare provider for advice specific to you.

Will Wegovy Still Work If I Drink Alcohol?

Wegovy can still be effective if you drink alcohol occasionally. But regular or excessive alcohol consumption negatively impacts your health. It may also reduce your ability to lose weight on the medication.

Alcohol can interfere with weight loss efforts, as many alcoholic drinks contain a lot of sugar, without providing nutritional value. It can also impact your judgement around food. This can make it difficult to make healthier food choices, which may reduce the effectiveness of your weight loss medication.

To get the best results from Wegovy, we recommend either not drinking alcohol at all or drinking in moderation. Focus on maintaining healthy eating and lifestyle habits throughout your weight loss journey.

There’s no completely safe level of alcohol consumption. The NHS recommends limiting the amount of alcohol to no more than 14 units a week. That equates to six medium (175ml) glasses of wine, or six pints of 4% beer. And you should spread your drinking across three days or more.

Does Wegovy Affect Alcohol Cravings?

Emerging research and reported experiences from Wegovy users suggest that Wegovy may reduce alcohol cravings in some individuals. One study found that participants reduced their drinking by an average of 1.5 alcoholic drinks after starting Wegovy.

So why might this happen? As a GLP-1 receptor agonist, Wegovy affects areas of the brain involved in appetite, reward, and impulse control. These mechanisms also play a role in substance use behaviors.

Several studies have shown that Wegovy can lead to a noticeable decrease in alcohol consumption and binge-drinking episodes. Many patients also report a reduced desire to drink while on Wegovy, even if they previously consumed alcohol regularly.

More large-scale clinical trials are needed to confirm these effects. However, current evidence points to a potential added benefit of Wegovy for individuals who struggle with alcohol cravings.

Lower-Risk Drinking Tips While on Wegovy

If you choose to drink alcohol while taking Wegovy, follow these safer drinking tips. They can help minimise side effects and support your weight loss journey.

• Always Drink in Moderation: Stick to the recommended guidelines of one standard drink per day for women and up to two for men.
• Eat Before You Drink: Avoid drinking on an empty stomach to reduce the risk of nausea and stomach irritation. It can also make you less likely to make healthy food choices after drinking.
• Drink Plenty of Water: Stay well-hydrated by drinking plenty of water alongside alcoholic beverages. Pay close attention to how your body reacts, especially during the initial weeks of treatment.
• Watch For Signs of Low Blood Sugar: Since alcohol can lower blood sugar, be mindful of symptoms like dizziness or weakness. Particularly if you’re taking other diabetes medications.
• Talk to Your Clinician: They can help tailor your treatment plan and provide personal advice on your alcohol consumption.
• Try Some Non-Alcoholic Alternatives: Mix it up with non-alcoholic drinks, like kombucha, ice tea sparkling water with fruit and/or herbs. Or try a new mocktail, like a virgin mojito.

When to Avoid Drinking Alcohol on Wegovy

You may need to avoid alcohol while on Wegovy in certain situations. This will ensure your safety and maximise treatment effectiveness.

For example, you should avoid alcohol if you’re experiencing side effects, such as nausea, vomiting, dizziness, or stomach discomfort. These are more common during the early weeks of starting Wegovy. As mentioned before, alcohol can make you feel worse. You should also avoid it during periods of illness and dehydration.

We advise you to avoid alcohol if you have diabetes. Or if you are taking other medications that affect blood sugar levels. Combining alcohol with Wegovy may increase the risk of low blood sugar.

You should not drink and drive on Wegovy. Wegovy may increase the effects of alcohol on your body (you might get drunker quicker). So even small amounts of alcohol could put you over the legal drinking limit in the UK. In Scotland, there’s no safe legal limit.

Consult your healthcare provider on when you can drink alcohol on Wegovy. They can help you find the safest approach based on your lifestyle and medical history.

Key Takeaways

• Alcohol Increases Your Risk of Side Effects: It can intensify side effects. Especially during the early stages of treatment. The most common ones are nausea and vomiting.
• Alcohol Makes It Harder to Make Healthy Choices: Drinking can affect decision making around food. This can potentially reduce Wegovy’s effectiveness.
• Wegovy May Reduce Cravings: Some patients report drinking less. Researchers found the medication can lower alcohol cravings.
