Can I Have Wine on Mounjaro? (October 2026)

01 · The honest answer

So, can you have wine on Mounjaro?

Many people ask this the week they start, and the honest answer is that it depends on you. Mounjaro is a once-weekly tirzepatide injection licensed in the UK for weight management and type 2 diabetes¹. There is no direct interaction between Mounjaro and alcohol, but drinking on a reduced appetite and emptier stomach can hit harder than usual.

It activates the GIP and GLP-1 receptors, which help regulate appetite and slow how quickly the stomach empties¹. Most people feel fuller sooner and less hungry between meals. That is the effect you are paying for, and it is worth thinking about before you pour a drink.

02 · Your decision

What to decide before you pour a glass

There are two practical questions. First, are you currently having side effects? If you feel unwell, a wine night is a poor test of how your body is coping. Second, does wine fit the plan you are following? Treatment is used alongside a reduced-calorie diet and increased physical activity¹, and wine contributes calories without helping you feel satisfied.

If you are weighing up specific drinks, our guides on having a glass of wine and on drinking red wine go into more detail. If you are already a customer, your prescribing team can advise at your monthly review. If you are still deciding whether treatment is right for you, start with the Mounjaro pen and free online consultation.

03 · Stomach emptying

Why a slowed stomach matters with alcohol

Tirzepatide helps slow how quickly the stomach empties¹. In practice, that means you may feel full on far less food, and a drink may sit differently than it used to.

What you can do is pay attention to your own response, especially in the first few weeks and after each dose increase. Side effects are most likely when starting treatment or moving up a dose, so a drink that was fine on 2.5mg may feel different at a higher strength. If something feels off, stop and tell your prescriber.

04 · Calories and goals

Wine, calories and weight-loss goals

Wine counts towards your intake, and trial results came from people combining tirzepatide with a reduced-calorie diet and exercise².

Alcohol is often described as a source of liquid calories, so frequent drinking can work against the plan the medicine supports. A related question is whether wine suppresses appetite, which is worth reading before you assume it helps.

05 · Other medicines

If you take diabetes medicines too

If you take insulin or a sulfonylurea alongside Mounjaro, alcohol increases the risk of low blood sugar, and doses of those medicines may need adjusting¹³. That is a reason to speak to your prescriber before drinking, not a ban.

06 · When to get advice

New symptoms and reporting side effects

If you notice a new symptom after drinking on Mounjaro, speak to your prescriber rather than assuming it is normal. You can also report suspected side effects through the MHRA Yellow Card scheme¹⁹.

Mounjaro (tirzepatide) is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber. This page is information, not a substitute for medical advice.

07 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. Seek immediate medical help for: severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹
