Mounjaro Australia - Comprehensive Patient Guide



Mounjaro is the latest prescription medication that is available to Australian patients to control type 2 diabetes. It lowers blood glucose levels and decreases appetite, which generally causes weight loss. Mounjaro is colloquially known in Australia as the "Ozempic that's actually available" and has gained popularity for its off-shelf use as a fat-loss medication. It's important to understand that it is a prescription medication and requires screening and additional monitoring from a doctor to be taken safely.

To get the best results with Mounjaro, it needs to be incorporated with an appropriate diet and training program. A protein-rich, low-caloric diet is ideal, which works synergistically with a resistance training program and active lifestyle. This combination will promote weight loss predominantly from fat and not muscle.

Mounjaro's active ingredient is tirzepatide, which is highly effective to both treat diabetes and reduce body weight. It affects two receptors that work harmoniously, in turn lowering blood sugar and reducing hunger, both causing weight loss in many people. Mounjaro has recently gained popularity as Ozempic has supply issues across Australia and is almost impossible to find in pharmacies. Many Ozempic patients are moving to Mounjaro.

Due to its availability in Australia, many health professionals are now prescribing Mounjaro instead of Ozempic and Saxenda. It's important to note that Mounjaro costs approximately double that of Ozempic and other similar medications, which needs to be considered when choosing the most appropriate treatment for a patient.

What is Mounjaro?

Mounjaro (active ingredient tirzepatide) is a prescription-only medicine in Australia and is manufactured by Eli Lilly. Mounjaro has been approved by the TGA (Therapeutic Goods Administration) to treat adults with type 2 diabetes in Australia. Mounjaro has recently gained popularity for its off-label use as a weight loss medication.

Mounjaro is a medication that is injected once a week into stomach fat (subcutaneously). Mounjaro comes in small vials that must be refrigerated (between 2-8 degrees Celsius). The medication can not be used if it has ever been frozen.


How Does Mounjaro Work?

Mounjaro's dual-action mechanism targets glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. This unique approach enhances insulin secretion and reduces glucagon secretion in a glucose-dependent manner, effectively controlling blood sugar levels.

Concurrently, it acts on appetite centres in the brain, reducing hunger and caloric intake, thus contributing to weight loss. This multifaceted mechanism sets Mounjaro apart from other diabetes medications, which predominantly focus on glycaemic control.

Appetite Suppression and Weight Loss

The mechanism of appetite suppression by Mounjaro is central to its efficacy in weight management. It interacts with brain receptors responsible for fullness, thereby reducing caloric consumption and aiding in weight loss, making it a potent agent for managing diabetes and obesity.

Stomach pain and discomfort are commonly felt when patients who are taking Mounjaro eat larger meals. These two mechanisms make sticking to a lower caloric diet.


Mounjaro for Weight Loss in Australia

Mounjaro is not recommended as a stand-alone treatment for weight loss. The medication must be taken with a low-caloric diet and regular exercise for optimal results.

Clinical trials have consistently shown Mounjaro's effectiveness in promoting significant weight loss, often exceeding 15%. This level of weight reduction is noteworthy in obesity treatment, with patients reporting decreased body weight and improved health markers associated with obesity.


Best Mounjaro Diet for Weight-Loss

Mounjaro reduces one's appetite, making it much easier to stick to a low-calorie diet. People often also feel nauseous when they consume larger meals when they are taking the medication.

Optimal Mounjaro diets follow the following rules:

  1. Low calories - Around 500 calories below your Basil Metabolic Rate.
  2. High Protein - You want the weight loss to come from fat, not muscle.
  3. Smaller meals - Large meals often cause stomach discomfort and nausea, the medication's most common side effects.

      Speaking to a dietician will get you the best results. It is also recommended to track all calories through MYFITNESSPAL.

      Mounjaro vs Ozempic

      Both Mounjaro and Ozempic are used in diabetes management and weight control. Both medications are administered as a weekly subcutaneous injection.

      The two medications differ in their action mechanisms. Mounjaro’s dual-receptor activity on GIP and GLP-1 receptors leads to more pronounced effects in blood sugar control and weight reduction compared to Ozempic’s singular GLP-1 receptor action. Clinical trials have indicated Mounjaro’s superior efficacy in weight management and glycaemic control, making it a preferred choice for many patients.

      It is important to note that Mounjaro is significantly more expensive than Ozempic, nearly double the price. Mounjaro is currently readily available in Australian pharmacies, while Ozempic is not.


      Clinical Implications of Dual-Receptor Targeting

      Mounjaro’s dual-receptor targeting represents a significant advancement in diabetes and obesity treatment, addressing two crucial metabolic pathways. This comprehensive approach is instrumental in managing these interrelated conditions more effectively.

        Fat Loss Medication Myths

        Common misconceptions about fat loss medications like Mounjaro need addressing. Mounjaro is most effective as part of a comprehensive weight management plan, including a balanced diet, regular physical activity, and medical supervision. It should be seen as a tool to assist in weight loss, not a standalone solution.

        The Necessity of a Holistic Treatment Approach

        A holistic approach, integrating medication, lifestyle changes, and medical support, is critical for successful weight management. Mounjaro should be considered one component of this broader strategy.

        Mounjaro Treatment Plan

        A Mounjaro treatment plan typically starts with a lower dose, adjusted based on the patient's response and tolerance. Continuous monitoring by healthcare providers is essential to evaluate the medication's effectiveness and make necessary dosage adjustments.

        Importance of Regular Monitoring and Adjustments

        Ongoing monitoring is vital in Mounjaro's treatment. Healthcare providers must closely track the patient's response, adjusting the medication as required to achieve optimal health outcomes and minimize side effects.

        Mounjaro Side Effects

        Mounjaro is generally well-tolerated but may cause side effects such as nausea, abdominal pain, and hypoglycaemia. Patients should be informed about these potential reactions and encouraged to seek medical attention for severe or persistent symptoms.

        During the consultation, doctors should explain the signs and symptoms of a hypoglycaemic episode and how to prevent it with simple sugars (often lollies or juice).

        There are a number of extremely rare, but more serious side effects as well. Propper screening by a healthcare professional is essential as there are numerous contraindications to taking Mounjaro safely, many of which are other medicines.

        It is recommended that all patients read the consumer medicines information for Mounjaro before using the medication. The full list of potential side effects can be found within this document.

        The most common side effects are nausea and stomach discomfort. Both of these side effects can be often avoided by following the dosage protocol and avoiding larger meals. Please let your doctor know if you are experiencing any side effects.



        Mounjaro represents a significant advancement in the treatment of Type 2 diabetes and obesity in Australia. Consulting with a healthcare professional is crucial to taking the medication safely while also understand its potential benefits and risks.

        Mounjaro is not a stand-alone treatment and needs to be taken alongside an active lifestyle with a lower-caloric diet for optimal results.
