Alcohol doesn’t directly affect how Mounjaro works. But drinking alcohol during your Mounjaro treatment can worsen some of the drug’s side effects and make it more difficult to manage your blood sugar.

Doctors prescribe Mounjaro to help manage blood sugar levels in adults with type 2 diabetes. You can combine it with exercise and diet changes to improve your health.

Keep reading to learn how alcohol can worsen some of Mounjaro’s side effects.

You can drink alcohol or beer during Mounjaro treatment, but doctors advise being cautious.

Mounjaro’s manufacturer doesn’t note that Mounjaro and alcohol or beer can affect each other. But the manufacturer notes that the drug causes some gastrointestinal (GI) side effects.

Alcohol can cause some of these same side effects (see list in the next section). So drinking alcohol during your Mounjaro treatment increases the risk of these side effects occurring or worsening. You and your doctor can discuss this risk in more detail.

If you consume alcohol during Mounjaro treatment, it may be a good idea to avoid drinks with added sugar to help prevent a rise in your blood sugar levels. Examples of drinks with added sugar include certain cocktails like margaritas or piña coladas.

Mounjaro can cause GI side effects. So can alcohol, plus it can worsen Mounjaro’s GI side effects. These include:

  • nausea
  • vomiting
  • diarrhea
  • dehydration, if the above side effects become severe

Drink plenty of fluids such as water to help avoid (or lessen) these side effects.

If dehydration becomes severe, it can lead to kidney complications. Some symptoms of dehydration are:

  • headache
  • thirst
  • less urination than usual
  • urine that smells strong and is dark yellow
  • dry mouth, lips, and eyes
  • tiredness
  • dizziness

If you have GI side effects or dehydration symptoms, contact your doctor right away. Be sure to let them know whether the side effects or symptoms become severe or persist.

Some people may use Mounjaro along with other medications, such as insulin, to manage diabetes. This combination may cause low blood sugar, which can lead to blurry vision. This is a sign that blood sugar is low and needs treatment.

Drinking alcohol may also cause blurry vision, which may mask blurry vision caused by low blood sugar. Because of this, it may be beneficial to avoid alcohol use during your Mounjaro treatment. To learn more, talk with your doctor.

Mounjaro’s manufacturer doesn’t state that the drug causes cravings for alcohol.

In fact, a 2024 study showed a link between using GLP-1 drugs (such as Mounjaro) and reduced alcohol consumption in people with alcohol use disorder.

This study also noted a 40% lower rate of opioid overdose among people with opioid use disorder who used GLP-1 drugs.

Experts said these study results are promising, but more research is necessary into the connection between GLP-1s and decreased cravings for alcohol and opioids.

If you have diabetes, drinking alcohol can affect your blood sugar. Remember, Mounjaro is approved to help manage blood sugar in adults with type 2 diabetes. So drinking alcohol can make Mounjaro less effective. This can make it difficult to manage your blood sugar.

Drinking alcohol during your Mounjaro treatment can worsen some of the drug’s side effects. With diabetes, too, it’s important to be mindful if you drink alcohol during your Mounjaro treatment. This is because Mounjaro helps manage blood sugar in adults with type 2 diabetes. So drinking alcohol can make it more difficult for Mounjaro to manage blood sugar.

If you’re prescribed Mounjaro, ask your doctor whether it’s safe for you to drink alcohol during your treatment. Your doctor can advise how much, if any, alcohol is safe to drink during Mounjaro treatment.
