If you’re considering stopping Mounjaro, you’re likely wondering what changes you can expect in your body. This is a common question among patients weighing their options – whether due to cost considerations, side effects, or having reached their weight loss goals.
Mounjaro (tirzepatide) is a GLP-1 that works by mimicking hormones that control blood sugar and appetite. When you stop taking it, these effects gradually wear off, and your body and weight change if you aren’t following the right diet and exercise. Knowing what happens can help you decide what’s right for your situation and prepare for any changes ahead.
Following the Mounjaro September 2025 price increase, many patients are now paying significantly more for their monthly supply. This sudden jump in costs has made treatment unaffordable for many who were managing the previous pricing structure.
While nausea, vomiting, and stomach problems often improve as your body adjusts, some people find these effects too uncomfortable to continue. The side effects can be particularly challenging when increasing doses, leading some patients to stop rather than push through to higher, more effective doses.
When people reach their target body weight, they want to test whether they can maintain their results without ongoing injections. This is common for those who’ve achieved substantial weight loss and feel confident about their new eating habits.
You might need to pause treatment because of a planned surgery, pregnancy, or other medical conditions that make continuing inadvisable. In these cases, stopping is typically temporary until it’s safe to resume treatment.
When you stop taking Mounjaro, the medication gradually leaves your system over about a month. The changes don’t happen overnight – most people begin noticing differences within the first few weeks as the drug’s effects fade.
The timeline varies from person to person, but the process is generally predictable. Your body starts returning to its pre-treatment state as the medication clears from your system.
Your appetite might return to pre-treatment levels, feeling stronger than you remember. Some people report feeling hungrier than they did before starting Mounjaro, particularly in the first month after stopping. Food cravings, especially for high-calorie foods, become more intense as the brain’s hunger signals are no longer suppressed.
People can regain some weight after stopping the medication. Studies show that some patients can regain up to two-thirds of their lost weight within a year without the medication’s appetite-suppressing effects or any weight management plans – but this will be different for everyone.
Your digestive system starts to return to its normal speed. Food starts to move quickly through your stomach, and you may notice you get hungry more quickly after meals and don’t feel full for as long.
For people with diabetes, blood sugar levels will likely rise as the medication’s glucose-lowering effects diminish. Regular monitoring becomes especially important during this transition period, and alternative treatments may be needed.
Some people report changes in their mood or energy levels when stopping. This could be related to blood sugar fluctuations, changes in eating patterns, or the psychological impact of not having the medication’s support.
You may regain at least some of the weight you lost while on Mounjaro. This isn’t a failure on your part – it’s simply how your body responds when the medication’s appetite-suppressing effects are removed.
A major study followed 670 participants for 36 weeks after they stopped tirzepatide treatment. The results showed that people who had lost an average of 20.9% of their body weight while on the highest dose began regaining weight steadily after stopping. By week 36 (about 8 months later), participants gained up to 14% of their weight back.
The amount of weight you’ll regain when you come off weight loss drugs depends on your lifestyle changes. People who adopt new eating habits, increase physical activity, or address emotional eating patterns tend to maintain their weight loss.
It also matters how much weight you lost initially. If you lost a large amount of weight, you might regain more pounds, but you’ll often still weigh less than when you started treatment.
Some people notice the scales creeping up within weeks of stopping, while others maintain their weight for several months before gradual regain begins. Most of the regain typically occurs within the first year after discontinuation.
Before you stop, make sure you’ve thought through your decision. Are you stopping due to cost, side effects, or because you’ve reached your goals?
If it’s side effects, consider whether dropping to a lower dose might help – many people find 2.5mg or 5mg more tolerable than higher doses while still providing some benefit.
If you have diabetes, your prescriber (doctor or pharmacist) needs to help you plan alternative blood sugar management before you stop. They may prescribe metformin, other diabetes medications, or adjust existing treatments.
For weight loss patients, while not always necessary, your provider can offer guidance on maintaining your results and may suggest alternative treatments.
Before you take your last injection, have a detailed weight management plan ready. This should include specific meal planning (continuing with smaller portions you learned on Mounjaro), regular exercise schedules, strategies for managing cravings, and possibly working with a nutritionist or dietitian.
You have two main options when stopping Mounjaro:
You can simply skip your next weekly injection and stop completely. This approach means you’ll need to be prepared for some rebound weight gain and the return of your appetite within 1-2 weeks. Focus on implementing lifestyle strategies immediately to manage your hunger, including eating high-volume, low-calorie foods and staying well-hydrated.
Alternatively, you can reduce your dose gradually – perhaps dropping from 15mg to 10mg, then 7.5mg, then 5mg over several weeks or months. Your hunger levels will adjust more gradually, but you’ll still need lifestyle changes to manage your appetite at each step.
Watch for the return of your appetite and any blood sugar changes if you have diabetes. Side effects like nausea and stomach upset should improve within 3-7 days.
As your appetite comes back, put your pre-planned strategies into action immediately. Don’t wait until you’ve already gained weight to start managing your eating habits. You could weigh yourself regularly and have trigger points for when to seek additional support.
Focus on maintaining the portion control you learned while on Mounjaro. Use the “plate method” by filling half your plate with vegetables, a quarter with lean protein, and a quarter with complex carbs. This visual guide helps maintain proper portions without needing to count calories.
Drink a large glass of water 15-20 minutes before eating to help you feel fuller, partially mimicking the delayed stomach emptying that Mounjaro provided.
Plan your meals in advance and designate specific eating times rather than grazing throughout the day. Practice mindful eating by eating slowly, putting your fork down between bites, and paying attention to hunger and fullness cues. Since Mounjaro was helping regulate these signals, you’ll need to retrain yourself to notice them naturally.
Plan ahead for social events and gatherings by eating something protein-rich before going out, or have protein shakes available as filling, lower-calorie options when hunger strikes.
Exercise becomes even more important after stopping Mounjaro. Focus on both cardiovascular exercise and strength training to build muscle, which burns more calories even at rest. The NHS recommends aiming for at least 150 minutes of moderate activity per week.
Find activities you enjoy rather than forcing yourself into exercise routines you hate. This might be dancing, hiking, swimming, or playing sports. The key is consistency rather than intensity.
40% of people will increase their food intake when they’re stressed, bored, or emotional. Since Mounjaro was helping suppress these urges, you’ll need alternative strategies. This might include meditation, talking to friends, walking, or finding hobbies that keep your hands busy.
Consider working with a counsellor or therapist who specialises in eating behaviours if you find yourself struggling with emotional eating patterns that return after stopping the medication.
Find a weight maintenance buddy – someone else who’s maintaining weight loss or has similar goals. Check in weekly, share meal ideas, and hold each other accountable. Having support makes a huge difference in long-term success.
Monitor your weight regularly by weighing yourself weekly at the same time and day. Set trigger points – perhaps if you gain 5 pounds, you’ll tighten up your eating habits, or if you gain 10 pounds, you’ll seek professional help or consider restarting medication.
It’s generally safe to stop and restart Mounjaro. However, there are a few things to keep in mind when restarting.
If you’ve been off Mounjaro for more than a few weeks, you’ll likely need to start back at a lower dose rather than jumping straight back to where you left off. Most doctors recommend restarting at 5mg and working your way back up, especially if you’ve been off the medication for several months.
You might find that side effects return when you restart, even if you had gotten used to them before. Nausea, stomach upset, and other digestive issues often come back as your body readjusts to the medication. These typically improve again within a few weeks as you return to the routine.
The weight loss effects return relatively quickly once you restart, though you might not lose weight as rapidly as you did initially. Your body has some “memory” of the medication, but it still takes time to suppress your appetite and slow digestion again.
Some people skip a week of Mounjaro or use planned breaks as part of their long-term strategy – like taking summers off or pausing during stressful periods when they know they won’t be able to focus on weight management. This can be a reasonable approach as long as you’re prepared for weight regain during the breaks and have realistic expectations about restarting.
Just remember that once you’ve opened a Mounjaro pen, it must be used within 30 days, so timing your breaks around your medication supply makes sense.

You don’t have to stay on Mounjaro forever, but it’s important to have realistic expectations about what happens when you stop. Mounjaro isn’t a permanent cure for obesity or weight issues – it’s a tool that helps while you’re taking it.
Many people do choose to stay on it long-term because it’s effective for maintaining weight loss and, for those with diabetes, managing blood sugar. However, others use it for a specific period to lose weight and then try to maintain their results with lifestyle changes alone.
The decision about how long to stay on Mounjaro should be made with your doctor or pharmacist, taking into account your health goals, financial situation, and how well you’re maintaining other healthy habits.
You can take short breaks from Mounjaro if needed. A week off won’t cause any serious problems, though you might notice your appetite starting to return by the end of that week.
Some people take planned breaks for holidays (as they don’t want to travel with Mounjaro and worry about keeping the medication cool) or special occasions. Others might skip a dose if they’re feeling particularly unwell or have had severe side effects.
However, keep in mind that even short breaks can disrupt your progress. Your appetite suppression will start to fade, and you might find it harder to stick to smaller portions. If you’re taking Mounjaro for diabetes, your blood sugar levels may also start to rise during the break.
For breaks longer than a couple of weeks, you should discuss this with your healthcare provider first.
No, there aren’t any withdrawal symptoms in the traditional sense when you stop Mounjaro. You won’t experience things like shaking, sweating, or feeling physically unwell from not having the medication.
What you will experience is the return of your normal appetite and digestive function as the medication leaves your system. This can feel quite dramatic if you’ve gotten used to having little appetite, but it’s not a withdrawal symptom – it’s just your body returning to its pre-treatment state.
Mounjaro has a half-life of about 5 days, which means it takes roughly 5 weeks (about 35 days) for the medication to be completely eliminated from your system.
However, you’ll start noticing changes well before it’s completely gone. Most people begin to feel their appetite returning within 1-2 weeks of their last injection, as the medication levels drop below the therapeutic threshold.
The effects on blood sugar control also start to fade within the first couple of weeks, which is why people with diabetes need to have alternative management strategies in place before stopping.
There’s no minimum waiting period required before restarting Mounjaro. You can restart as soon as you want to, whether that’s after a few days, weeks, or months.
However, if you’ve been off the medication for more than a few weeks, most doctors recommend starting back at a lower dose (5mg) rather than jumping back to your previous dose. This helps minimise side effects as your body readjusts to the medication.
The longer you’ve been off Mounjaro, the more likely you are to experience side effects again when restarting, so it’s worth building back up gradually even if you were previously tolerating higher doses well.
