Like all GLP-1 weight loss injections, Mounjaro (tirzepatide) is a long-term treatment for obesity and weight management \u2013 it’s not a \u201cquick fix\u201d.<\/p>\n\n\n\n

So if you\u2019re thinking of using Mounjaro for weight loss and weight management, you may be wondering how long you will be taking it for. You might also be weighing up the risks and benefits of using Mounjaro long-term.<\/p>\n\n\n\n

To help you make an informed decision about your treatment, this article answers key questions about how long you can use Mounjaro for. And we\u2019ll give you tips for successfully staying on Mounjaro for weight maintenance<\/a>.<\/p>\n\n\n\n

How Long Do You Use Mounjaro For?<\/h2>\n\n\n\n

Providing the treatment works for you, you should use Mounjaro<\/a><\/strong> at least until you reach a healthy weight. This varies from person to person, and your healthcare provider will help determine the safest target weight for you.<\/p>\n\n\n\n

How long this takes will depend on several factors. These include your starting weight and any progress you\u2019ve made with a balanced diet and regular exercise.<\/p>\n\n\n\n

Research has shown you can expect to lose around 8%<\/a> of your initial body weight in the first 12 weeks of treatment with Mounjaro. You can expect an average weight loss around 12-15% of your bodyweight within the first 24 weeks and 15%-20% after 72 weeks.<\/p>\n\n\n\n

However, these are averages. Everybody is different and you will lose weight at your own pace. Your weight loss and management plan is tailored to you and supervised by a clinical team. Incorporating good habits, like eating more whole foods and exercising, will naturally boost your results from the treatment.<\/p>\n\n\n\n

Once You Reach a Healthy Weight<\/h3>\n\n\n\n

Once you achieve a healthy weight, you have two choices<\/strong>: <\/p>\n\n\n\n

    \n
  1. Stop taking Mounjaro<\/li>\n\n\n\n
  2. Continue Mounjaro at an appropriate dose for maintenance<\/li>\n<\/ol>\n\n\n\n

    If you stop taking Mounjaro, you can discontinue the medication immediately, or you can taper the dose down gradually. This latter approach may give you some more time to consolidate the lifestyle changes that will help you maintain your new healthy weight<\/a>. <\/p>\n\n\n\n

    If you continue taking Mounjaro, your healthcare provider will advise you on the appropriate dose for you. This will help you maintain weight at healthy levels without further weight loss.<\/p>\n\n\n\n

    If you are a patient with Simple, we are here to help you every step of the way. And we will support you with the right ongoing treatment plan. So contact us<\/a> if you have any questions about your weight loss journey.<\/p>\n\n\n\n

    Can You Stay on Mounjaro Forever?<\/h2>\n\n\n\n

    There is no limit on how long you can take Mounjaro, meaning you can continue the treatment indefinitely.<\/p>\n\n\n\n

    However your healthcare provider should only continue prescribing Mounjaro if you are still tolerating it and benefiting from it. For example, you\u2019re losing weight or maintaining weight loss and you\u2019re not experiencing side effects while benefiting from a reduction in food noise. Your prescriber will review your progress and provide recommendations.<\/p>\n\n\n\n

    You also do not have to stay on Mounjaro forever. Once you have achieved a healthy body weight, you can stop taking Mounjaro.<\/p>\n\n\n\n

    Building healthy habits while taking Mounjaro can help you retain your healthy weight once you stop taking it. The medication also helps regulate your eating habits. With enough practice, these new habits will help you maintain weight loss.<\/p>\n\n\n\n

    However, some people notice their appetite goes back to normal when they stop using Mounjaro. This makes it hard for them to keep their new healthy weight. To avoid this, many people will choose to stay on Mounjaro to keep on top of the weight moving forward.<\/p>\n\n\n\n

    The Benefits of Staying on Mounjaro Long-Term<\/h2>\n\n\n\n

    The main benefit of using Mounjaro long-term is that it helps you keep a healthy weight, as it reduces your appetite and makes you feel full faster.<\/p>\n\n\n\n

    A healthy body weight comes with several other health benefits. This includes a reduced risk of high blood pressure, cardiovascular disease, type 2 diabetes and other weight-related medical conditions.<\/p>\n\n\n\n

    If you feel that you have made sufficient improvements to your lifestyle when taking Mounjaro, you may be able to stop the medication and maintain a healthy weight on your own.<\/p>\n\n\n\n

    However, some people find that once they stop taking Mounjaro<\/a>, their appetite and food noise returns to the previous levels and they become prone to overeating again. This can lead to people regaining the weight they had lost previously. (That\u2019s why we work alongside our patients to educate them on the importance of a healthy diet, exercise and mindset shifts.)<\/p>\n\n\n\n

    Taking Mounjaro long-term gives you more time to gauge how you feel at different doses and helps you determine if you’re ready for maintenance dose.<\/p>\n\n\n\t\t

    Is It Safe to Use Mounjaro Long-Term?<\/h2>\n\n\n\n

    While there\u2019s no published data on its long-term use, there are currently no major concerns about long-term side effects of Mounjaro and other similar treatments.<\/p>\n\n\n\n

    Mounjaro is a relatively new drug and first of its kind, only being approved for use in diabetes<\/a> in 2022. We therefore have little information about the possible long-term effects.<\/p>\n\n\n\n

    Mounjaro is also the first drug of its kind. Unlike Wegovy or Saxenda \u2013 which contains the hormone glucagon-like peptide 1 (GLP-1) \u2013 Mounjaro also contains GLP-1 and glucose-dependent insulinotropic polypeptide (GIP).<\/p>\n\n\n\n

    Since there are no similar drugs to compare with Mounjaro, we need to wait for long-term studies. These studies will help us understand the specific long-term effects of this unique dual receptor agonist.<\/p>\n\n\n\n

    However, there are studies on the long-term effects of other GLP-1 agonists, which may shed some light on the risks and benefits of taking Mounjaro long-term<\/p>\n\n\n\n

    One study, published in 2022, explored the effects of GLP-1 agonists on the thyroid, kidney and cardiovascular health<\/a> over a five-year period. The study found a lower risk of mortality in people taking GLP-1 agonists and that the medications have protective effects on kidney and cardiovascular health. <\/p>\n\n\n\n

    The study did reveal that there may be a small increased risk of thyroid cancer in people taking GLP-1 agonists. However, this was not statistically significant, which means that cases of thyroid cancer may have had a completely different cause.<\/p>\n\n\n\n

    For these reasons, GLP-1 agonists are deemed safe and effective drugs for long-term use that can actually improve your health over time. In the next few years, we can expect more research on the long-term use of Mounjaro specifically.<\/p>\n\n\n\n

    Tips for Staying on Mounjaro Long-Term<\/h2>\n\n\n\n

    Once your body gets used to Mounjaro, taking it long-term is quite straightforward.<\/p>\n\n\n\n

    However, there are some things you can do to make staying on Mounjaro easier. This includes managing side effects and getting support from your doctor or healthcare provider.<\/p>\n\n\n\n

    Manage Side Effects<\/h3>\n\n\n\n

    Like all medications, Mounjaro does carry a risk of side effects. Although you are more likely to experience side effects when you start taking medication or when your dose increases.<\/p>\n\n\n\n

    However, finding a way to manage your side effects may help you to stay on Mounjaro long-term.<\/p>\n\n\n\n

    The most common side effects of Mounjaro<\/a> affect the digestive system. This includes burping, constipation, diarrhoea, nausea, vomiting and abdominal discomfort. Other common side effects include weakness, tiredness, general unwellness, low blood pressure, hair loss and hypersensitivity (allergic) reactions at the injection site.<\/p>\n\n\n\n
