Mounjaro and Wegovy at Christmas: Can you skip a week, pause your dose or take a holiday break?

There is a special kind of chaos that arrives with the silly season. Routines slip, social plans multiply, and suddenly you're trying to balance family lunches, last-minute shopping, long travel days and a medication schedule that felt simple a month ago.

Suppose you're on a GLP-1 medication such as Mounjaro or Wegovy. It's completely understandable to wonder whether you should stick to your usual schedule or make a change so you can enjoy Christmas without overthinking.

Let's walk through what is happening in your body, what the options really look like, and the questions worth raising with your prescriber before making any changes.

Support doesn’t pause for Christmas, and neither should your confidence in your health decisions.

Why Christmas feels different when you're taking a GLP-1

The festive season often brings a kind of eating and socialising that may not look anything like an ordinary month. When festive foods, alcohol and irregular routines collide with the way GLP-1 medications work, your body can sometimes react in ways that catch you off guard.

How Mounjaro and Wegovy work

Medications like Mounjaro (tirzepatide) and Wegovy (semaglutide) work with your body's appetite and blood sugar systems. They:

• Help you feel full sooner and for longer [1]
• Slow down how quickly food leaves your stomach [2][3]
• Support more stable blood sugar levels [4]
• Reduce the constant chatter about what to eat next, also known as food noise [5]

They are designed to be taken once a week so that the level of medication in your body stays relatively steady over time. That steady state is part of what keeps your appetite and weight more stable as well.

Why food and alcohol hit harder in December

Now add the December overlay. Christmas often means:

• Bigger, more flavoursome meals
• Multiple courses in one sitting
• More alcohol than usual
• Grazing boards that never seem to be cleared
• Late nights and irregular meal times

Because GLP-1 medications slow gastric emptying and can sometimes cause side effects such as nausea, indigestion or reflux, heavy festive meals and extra alcohol can sometimes make those symptoms worse [2][3][6].

You might also notice:

• Feeling full very quickly
• A "heavy" or uncomfortable sensation after eating
• More noticeable heartburn or burping
• Additional bloating after eating
• Extra fatigue after big nights

None of this means you cannot enjoy Christmas. It simply explains why your usual festive habits might need a small refresh now that you are on a weight loss injection.

December plans: Staying on, pausing or delaying your injection

Before you start weighing up whether to skip a week or take a break, it helps to step back and look at the bigger picture. December is rarely like any other time of year. Your eating patterns shift, your routine loosens, and you may find yourself travelling, socialising or navigating family dynamics that leave little room for predictability.

How you respond to all of this depends not only on your plans, but also on where you are in your treatment journey and why you're using a GLP-1 in the first place.

Questions to ask yourself before making any changes

Asking yourself these questions can be a useful check-in before you speak to your prescriber or decide to adjust anything on your own.

How long have I been on my medications?

Even though many people take the same medications, they're often at very different stages:

• Someone early in treatment, still increasing their dose, may be more sensitive to changes (and potentially more prone to side effects)
• Someone on a stable maintenance dose for weight only often has more flexibility
• Someone using the medication for both weight and diabetes will need to be much more careful

Why am I taking it?

Your reasons matter. If you're using a GLP-1 for weight management alone, a small dose adjustment might be manageable. If you're using it to help manage blood sugar, pausing or skipping a dose could have much bigger consequences. This is why one-size-fits-all advice (or opinions from other users) rarely works.

What does December actually look like?

Every December is different. Think about what you're potentially walking into:

• Travel
• Multiple social events
• A single big meal with family
• A quieter Christmas at home
• Work deadlines or long shifts
• Jet lag and time zones

Your plans help shape whether you stay on schedule, adjust your dose or delay an increase.

Why do many clinicians recommend staying on treatment over Christmas?

Although Christmas feels like a temporary chaos bubble, your body doesn't see it that way. GLP-1 medications work best when taken consistently, which is why many clinicians prefer patients to adhere to their regular schedule if possible.

Staying on treatment helps:

• Keep appetite more predictable during a high-food environment
• Reduce the pressure to "control yourself" when food noise is already lower on treatment
• Support stable blood sugar levels if you're living with diabetes
• Avoid the side effects that can appear when restarting after a pause

Staying the course doesn't mean Christmas becomes restrictive; it often makes it easier to enjoy yourself without slipping into patterns that feel out of control.

When it may make sense to delay a dose increase (not pause the medication)

There's a difference between skipping a dose and simply holding off on an increase. If your next dose escalation falls right before a big event (Christmas lunch, a flight, a wedding or a week of back-to-back social plans), delaying the increase for a week or two can be the more comfortable choice.

This is because:

• Higher doses can sometimes bring stronger digestive side effects until your body adjusts
• Those side effects usually show up in the first few days after increasing your dose
• Christmas week is already physically demanding, and adding nausea can feel overwhelming

Delaying an increase keeps you on treatment while giving your body a calmer environment to adjust later on. Clinicians often see this as a more measured option rather than pausing altogether.

Managing your Mounjaro or Wegovy schedule over Christmas

Once you've looked at your month as a whole, the next step is understanding what different schedule changes actually mean. A missed dose, a shifted dose and a break from treatment all have different implications for your body. Knowing the difference helps you make choices that feel both safe and intentional.

Changing your dose day

The simplest thing to do to enjoy your holiday is to simply move your injection day. Whether it lines up with travel, social events or big meals, it is usually ok to swap days (within certain boundaries, of course). Like any changes to medication, ensure you follow the instructions in the manufacturer's patient leaflet.

You are generally safe to move your injection by a few days, as long as the gap between doses doesn't become too short or too long.

Think of your weekly injection as a rhythm your body settles into. Sudden changes, especially big swings, can disrupt that rhythm. Small, one-off shifts are usually easier for your body to handle.

What is the difference between a late dose, a skipped dose and a break?

Understanding the terminology helps you avoid making a decision you didn't mean to make.

A late dose is when you inject later than planned, but still within the "make-up" window in the medication instructions. You then return to your usual routine.

A skipped dose is when you miss the window entirely and do not take that dose. The gap between injections becomes longer than usual.

A break is when you intentionally plan to skip one weekly dose with the intention of restarting the following week, or when you stop treatment for several weeks. Depending on the length of the break, it behaves more like stopping medication altogether rather than simply missing a dose.

Skipping a week or missing a dose over Christmas

If you miss a dose unintentionally or consider skipping on purpose, what you do next depends on the medication you are using.

If you miss or skip a Mounjaro dose

If you realise you forgot your injection, you can take the missed dose as soon as possible, within 4 days (96 hours) after the missed dose. If more than 4 days have passed, you will need to skip the dose and take the next one on your usual day [7][8]. Mounjaro doses must not be taken within 3 days of each other [7].

If you miss or skip a Wegovy dose

If you forgot to inject a dose and [9]:

• If it has been 5 days or less since you should have taken Wegovy, take it as soon as you remember. Then inject your next dose as usual on your scheduled day.
• If it has been more than 5 days since you should have taken Wegovy, skip the missed dose. Then inject your next dose as usual on your next scheduled day. Do not take a double dose to make up for a forgotten dose.

When skipping is riskier

Skipping or delaying doses carries more risk if you have:

• Type 2 diabetes
• Recently increased your dose
• Had strong stomach-related side effects in the past

In any of these situations, avoid making changes without medical advice.

Can you pause your GLP-1 for Christmas?

A planned pause may be appealing to those who want more appetite around Christmas meals. It's understandable. But it's important to know that pausing medication behaves differently from a simple late dose, and it does come with some considerations.

You can miss up to 2 doses without disrupting your dosing schedule. This allows you to inject within 14 days of your last dose [10].

During a pause, you may notice that your appetite returns quickly. For some people, this is fine; for others, it could feel overwhelming or uncomfortable. You may also experience some side effects when restarting, particularly if you are on a higher dose.

A short pause may be more manageable for people on a low or mid-level dose, not using the medication for diabetes and who have had minimal side effects so far. Likewise, a pause is not recommended for those who use a GLP-1 as part of their diabetes treatment or if they've struggled with side effects during dose increases.

If it has been more than 14 days since your last dose, you should speak to a clinician for dose review to avoid significant side effects.

Taking a longer break (2+ weeks) from Mounjaro or Wegovy

A longer break behaves much more like stopping treatment than skipping a dose. This is where appetite, weight and metabolic markers often shift more noticeably.

A break of several weeks can lead to:

• Increased hunger and more intense food cravings
• Possible weight regain (although this would be more of a gradual change)
• A return of "food noise"
• Greater digestive sensitivity when restarting

These changes aren't failures. They're simply how the medications work.

If it has been more than 2 weeks since your last injection, it is recommended to reduce your dose to prevent severe side effects due to the lower levels of medication in your body. This should not significantly impact your weight loss journey if you maintain a reduced-calorie diet and increased physical activity [10].

If December didn't go to plan and you've been off your medication for longer than expected, reach out to your prescriber. They can guide you to the safest restart point rather than guessing.

A quick holiday cheat sheet for missed, skipped or shifted doses

Here’s a simple guide to help you understand what to do if you’ve missed a dose, skipped a week, shifted your dose day or taken a longer break from Mounjaro or Wegovy during the Christmas period [7][9][10].

Travelling with Mounjaro or Wegovy over the holidays

Travel can add an extra layer of unpredictability to December. Long days in transit, changing climates, unfamiliar fridges and shifting time zones can all influence how and when you take your medication. A bit of preparation goes a long way in keeping everything running smoothly.

How to travel with Mounjaro or Wegovy

No matter where you are heading, the goal is to keep your pens safe, cool and accessible throughout the trip.

Mounjaro can last unrefrigerated for up to 30 days after first use or removal from the fridge, as long as the temperature does not exceed 30°C [7]. It does, however, need to be protected from light, so keeping it in its original container can help [7]. It is essential to keep the cap on the pen, though. Wegovy, on the other hand, can last unrefrigerated for up to 6 weeks after first use or being removed from the fridge, as long as it is stored in the original carton (with the cap on) between 8°C and 30°C [9].

When travelling by air, you should keep your Mounjaro Kwikpen or Wegovy pen with you or in your carry-on. Otherwise, the medication might freeze in the baggage compartment [9]. Most airports allow you to carry injectable medications and needles through security, but it's wise to also bring a prescription or a letter from your clinician and include it in your liquids for security screening. Always inform staff if asked about medication.

Although both medications can withstand up to 30°C, if you want to keep your medication on the cooler side or are worried about higher temperatures while travelling, you could use:

• A small insulated pouch
• Cooling gel packs (wrapped so they don't freeze the pen)
• A reliable hotel fridge once you arrive

It is imperative that you keep pens out of direct sunlight or hot cars. If you're staying somewhere where temperatures are above 30°C, ask your accommodation what cooling options they can provide.

You will need to plan ahead for needle disposal. Some people travel with a small, travel-size sharps container or a rigid, sealable container (if no official sharps bin is available). Some public restrooms may have a disposal unit available. Alternatively, at your destination, a local pharmacy or clinic can usually advise where to dispose of used needles safely.

Adjusting for time zones and events

Shifting your injection day because of travel is sometimes necessary. The key is to avoid large swings in timing that leave you with doses too close together or too far apart.

A simple rule is to make small, one-time adjustments rather than multiple changes throughout the trip. For example, if you're flying somewhere with a large time difference, you may choose to:

• Take the injection shortly before departure
• Take it after you land
• Or gently shift to the new time zone by adjusting the injection by a small window once

If you're unsure, your prescriber can help you decide the safest approach for your itinerary.

Travel days can be tiring and easily distracting, which can also make it easier to forget when you last injected. It helps to:

• Set a phone reminder
• Note the date and time of your last dose
• Keep your medication in your hand luggage rather than packing it into checked bags

If you are uncertain whether you've already taken a dose, don't inject again. Follow the skipped dose advice or call your clinician for more instructions.

What if you forget your pen while travelling?

It's a stressful moment, but trust us, this happens more often than you'd think. What you do next depends on how long you'll be away and how far you are from home.

If you're only away for a few days, you may simply miss that week's dose and restart when you return. Expect a temporary increase in appetite, and plan your meals with that in mind.

For longer trips, options depend on where you are travelling. Reaching out to your prescriber as soon as you realise the pen is missing gives you the best chance of finding a workable solution. You may need to see a clinician or pharmacist prescriber at your new destination to get a replacement pen, if available.

A quick check-in can save you from guessing and keep your holiday stress-free.

Enjoying your Christmas without derailing your progress

December is full of moments that revolve around food, drinks and togetherness. Being on a GLP-1 medication doesn't mean you have to sit out the fun; it just means approaching festivities with a bit of care and self-awareness. With the right mindset and a few practical strategies, you can enjoy what you love without feeling like you've "messed up" your hard work.

Planning Christmas Day

Christmas Day can be a marathon of eating, not a single meal. A little planning can help you enjoy what's on offer without feeling uncomfortable or overwhelmed.

Meal pacing

Because GLP-1s slow how quickly your stomach empties, eating quickly or piling your plate high can leave you feeling uncomfortably full. Try:

• Taking smaller portions to start with
• Pausing between courses
• Eating slowly enough to notice when you're satisfied
• Focusing on proteins and vegetables first (so it's carbs that are left if you don't have the room)

Let your appetite guide you rather than the pace of the table.

Choosing favourites

Not everything on the table needs to be eaten. Pick the dishes you genuinely love, the ones that feel special, and skip the items you're eating out of habit or politeness. This helps you enjoy Christmas food more, not less.

Avoiding binge-restrict cycles

Skipping breakfast or "saving up" for a big lunch often backfires. Arriving at the table over-hungry makes it harder to listen to your body. Eating regular meals, even if they're lighter, keeps your appetite steady and reduces the chance of overeating later in the day.

Office parties, family buffets & New Year’s Eve

These events can sneak up on you, one after another, and each one brings new food and drink decisions. Having a loose plan can help you feel in control without feeling rigid.

Multiple events

If December looks like a conveyor belt of celebrations:

• Eat a grounding meal with protein before you go
• Do a quick scan of the buffet before choosing anything
• Choose the foods that look the best and leave the rest
• Decide ahead of time how many drinks you're comfortable having

You'll feel better physically and emotionally if you take an "everything in moderation" approach.

Drinking and eating strategies

Pairing food with alcohol helps reduce nausea and dizziness. If you know you'll be drinking:

• Start with a non-alcoholic drink
• Alternate alcohol and water
• Choose drinks you can sip slowly
• Avoid very sweet cocktails that can aggravate reflux

It's the little habits that can make the night feel smoother, especially when you're on a higher dose.

Alcohol and GLP-1s during the silly season

Alcohol can feel a little different when you're taking a GLP-1. Because your stomach empties more slowly, drinks may hit harder or sooner than you're used to. Some people also notice that the effects last longer or come on later than expected, which can catch you off guard at a busy Christmas event.

Safer drink choices

Moderation matters, but so does the type of drink. Many alcoholic options are high in sugar and offer little nutritional value, which can make you feel worse in a month that's already full of rich food. Most people feel steadier with:

• Wine or champagne
• Spirits mixed with soda or a low-sugar option
• Light beers

Creamy cocktails, sugary mixers and very sweet drinks are more likely to trigger nausea, reflux or stomach discomfort, especially if you're on a higher dose.

Why empty-stomach drinking is harder

Drinking on an empty stomach is more likely to cause nausea, dizziness or a rapid spike in intoxication. Because alcohol sits in the stomach longer, having a snack or meal beforehand helps take the edge off and makes the night feel more predictable.

Hydration

Water may not be festive, but it works. Regular sips throughout the night can reduce headaches, support digestion and help you pace yourself without feeling like you're missing out. Alternating alcoholic drinks with water is a simple way to feel better both during the event and the next day.

Dealing with food FOMO, guilt & comments

Christmas can come with a side of pressure, from others and from yourself. It's completely normal to experience mixed feelings around food, especially if the medication has changed your appetite.

If someone comments on your portion size, appetite or medication, you don't owe them a detailed explanation. Simple responses work well, like "I'm pacing myself. I want to enjoy the whole day". Short and calm answers help shift the conversation without inviting more questions.

Enjoying Christmas food is not a setback. One day, or even a handful of festive meals, doesn't undo months of progress. What matters most is the overall pattern of your choices, not isolated moments.

You're allowed to eat foods you love, stop when you're full, and take part in traditions without the guilt. Progress and pleasure can coexist.

When to speak to a practitioner (or seek urgent help)

Most Christmas-related questions about GLP-1 can be sorted out with a quick message to your prescribing clinician, but there a times when a check-in is especially important. Reach out if you notice:

• Severe abdominal pain
• Ongoing vomiting
• Missing multiple weeks
• Blood-sugar concerns for people with diabetes
• Pregnancy or major illness

Frequently asked questions

The holidays can bring a lot of uncertainty: travel, big meals, shifting routines and a desire to actually enjoy the holidays. These are the questions people ask most often when Christmas and weekly injections collide.

Can I skip a week of Mounjaro just for Christmas?

Yes, many people can just skip one dose without major issues. Your appetite will likely increase for a few days, and you may feel hungrier at events than usual. If you use Mounjaro for diabetes or have recently increased your dose, skipping may be riskier, so speak to a clinician first.

Can I skip a week of Wegovy for my holiday?

A single skipped week is manageable, but you may notice a temporary return of cravings or reduced fullness. If you experience nausea with dose changes or are on a higher dose, the next injection may feel a little strong when you resume. Those taking Wegovy for diabetes should also avoid skipping without medical guidance.

Is it better to pause completely or just delay my next dose?

Delaying is typically easier on the body than pausing altogether. A small shift in timing (24-48 hours) can help you navigate travel or events without the side effects that sometimes occur when restarting after a longer break. Pausing completely should be a planned decision, not a spur-of-the-moment one, because appetite and cravings can tend to rebound quickly.

Will one skipped week undo my progress?

No. One week off doesn't erase months of work. You may feel a bit hungrier or more focused on food for a short period, but these changes are temporary. Your progress comes from long-term consistency, not a perfect streak.

I've missed two weeks. What should I do now?

If you're within a 14-day window from your last injection, many people still resume their usual dose safely. Expect your appetite to feel more during the gap. If you're approaching or past two weeks, you will likely need to restart at a lower dose to avoid strong side effects. Check in with your prescriber before injecting again.

What happens if my dose escalation falls on Christmas week?

It's often better to delay the increase by a week or two rather than escalate right before heavy meals, alcohol, or long travel days. Moving up a dose can bring temporary nausea or digestive discomfort, which can be harder to manage during the holidays. Staying at your current dose is usually a smoother option until the busy period settles.

Can I change my dose day so Christmas feels easier?

Yes. Most people can shift their injection by a day or two. Mounjaro requires at least 72 hours between doses, and Wegovy must be administered weekly. A small adjustment can help you avoid injecting immediately before a big meal or event. Those with diabetes or using higher doses should check with a prescriber before shifting.

What if I can't remember whether I've already taken this week's injection?

Skip the dose until you are certain. Taking two injections too close together can increase the risk of side effects. If you're unsure how to proceed, speak with a clinician who can help you safely reset your schedule.
