Key takeaways:
You shouldn’t drink alcohol while using Zepbound (tirzepatide). Alcohol can make Zepbound’s digestive side effects worse. Combining the two may raise the risk of experiencing nausea, stomach pain, and diarrhea.
Drinking heavily may also raise the risk of rare but serious Zepbound complications. These include pancreatitis (swelling of the pancreas) and kidney damage.
Drinking can also interfere with some of Zepbound’s benefits. Regular alcohol use can make it harder to lose weight while using Zepbound. And drinking (even occasionally) can worsen symptoms of obstructive sleep apnea.
You recently started Zepbound (tirzepatide) to help you lose weight. You’ve also been making lifestyle changes to support your weight-loss goals. But during a night out with friends, they order a round of drinks for everyone.
You hesitate for a moment. You know limiting alcohol is helpful when it comes to losing weight. But is it safe to drink at all while using Zepbound? Well, there’s no direct interaction between the two. But you still may want to avoid mixing alcohol and Zepbound. Here are six reasons.
Alcohol doesn’t directly interact with Zepbound. This means drinking doesn’t change how your body absorbs or clears the medication. But as we’ll detail below, alcohol can worsen certain Zepbound side effects. Drinking can also diminish some of the medication’s benefits.
So while Zepbound and alcohol don’t technically interact, it’s still recommended to avoid the combination.
There’s no set answer for everyone about whether you can have a drink or two while using Zepbound. Some people may find that an occasional alcoholic beverage is OK for them. Others might have more trouble with it.
A lot of what’s discussed in this article focuses on how heavy or regular alcohol use affects Zepbound treatment. Research on light or occasional use is more limited. But keep in mind that no amount of alcohol is considered “safe” for anyone to consume.
Ask your healthcare team whether you could have 1 or 2 drinks while using Zepbound. They should consider your health history and personal risks when providing an answer.
It’s common to experience digestive side effects while using Zepbound. These may include:
Nausea
Vomiting
Diarrhea
Constipation
Heartburn
Stomach pain
Burping
Gas
Most people find their side effects most bothersome when they first start Zepbound, or after increasing their dose. They tend to improve or go away once your body adjusts to the medication.
Alcohol can also cause similar digestive side effects. Combining Zepbound and alcohol may make these uncomfortable effects worse. This is especially true when you’re first starting Zepbound. But it’s possible to have these issues any time you mix the two, no matter how long you’ve been using Zepbound.
You’re likely familiar with the short-term effects of alcohol, such as the digestive side effects mentioned above. But drinking also has many long-term effects, especially drinking heavily. In particular, heavy alcohol use can cause pancreatitis (swelling of the pancreas) and kidney damage.
Other notable interactions: Read more about other Zepbound (tirzepatide) interactions — from insulin to birth control pills — and how to manage them.
More about side effects: Alcohol can worsen some of Zepbound’s side effects, including nausea, stomach pain, and diarrhea.
Medications not to mix with alcohol: There are many medications that interact with alcohol, some of which can have life-threatening consequences if combined.
Although very rare, people have also reported these serious complications while using Zepbound. More research is needed to know for sure, but drinking heavily while using Zepbound may raise your risk of developing pancreatitis or kidney damage. And if you have a history of either issue, your risk for them may be even higher.
What’s more, drinking alcohol can dehydrate you. And if Zepbound causes vomiting or diarrhea, this can also lead to dehydration. In severe cases, dehydration can damage your kidneys.
There are things that can make it more difficult to lose weight. Some factors, such as your age or genetics, aren’t things you can change. But drinking less alcohol is one way to help support your weight-loss goals.
Drinking both slows your metabolism and adds extra calories to your diet. Consuming alcohol, especially heavy or regular use, can fight against Zepbound’s weight-loss benefits. So it’s possible that you may not lose as much weight with Zepbound if you’re also drinking alcohol.
Besides weight loss, Zepbound is also FDA-approved to treat obstructive sleep apnea (OSA). If you’re living with OSA, there are foods and drinks that can hinder your sleep quality. Alcohol is one you should avoid if you have OSA.
Alcohol, even just an occasional drink, can have the following effects on your sleep:
It makes you more likely to wake up overnight.
It lowers your overall sleep quality, leaving you feeling less rested when you wake up.
It relaxes the muscles in your throat, which can block your airways.
It interferes with your ability to wake up if you stop breathing while sleeping. This means your body spends more time without oxygen.
If you’re using Zepbound for OSA, it’s best to avoid alcohol altogether. This isn’t because drinking necessarily makes Zepbound less effective. It’s because alcohol has negative effects for people with this condition.
It’s possible that you may have a lower desire to drink alcohol while using Zepbound. This is because of how Zepbound works.
When you drink alcohol, your brain releases a hormone called dopamine. Dopamine is like a reward for your brain. And it encourages you to drink again in the future.
Zepbound acts like two natural gut hormones:
Glucose-dependent insulinotropic polypeptide (GIP)
Glucagon-like peptide-1 (GLP-1)
Once injected, Zepbound attaches to GIP and GLP-1 binding sites (receptors) throughout your body. And there are binding sites in the reward center of your brain.
When Zepbound attaches to them, your brain may not react to dopamine as strongly as it usually does. So drinking alcohol may not give you as good of a feeling when you’re using Zepbound.
It’s not recommended to drink alcohol while using Zepbound (tirzepatide). While the two don’t directly interact, it’s still good to limit or avoid the combination.
Drinking can worsen Zepbound’s digestive side effects, such as nausea or vomiting. And heavy alcohol use may raise your risk for serious complications, such as pancreatitis (swelling of the pancreas) or kidney damage. What’s more, drinking alcohol regularly can make it harder to lose weight. And even the occasional drink can worsen obstructive sleep apnea symptoms.
Ask your prescriber before drinking alcohol while using Zepbound. They can let you know if it’s OK for you to have an occasional drink.
