Mounjaro was approved by the TGA in 2022 and was released in vials form in 2023. It is now available in Kwikpen formulation in Australia.

What is Mounjaro?

Mounjaro is a weekly prescription injection for adults with type 2 diabetes. It helps control blood sugar levels when used alongside diet and exercise. It contains tirzepatide, which is a combination medication mimicking GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors (glucose-like peptide) actions.

It works by increasing insulin and reducing sugar from the liver, helping lower blood sugar levels. It comes in either a user-friendly disposable pen with a built-in needle or a vial for drawing up injections. You can inject it into your lower abdomen, thigh, or upper arm. 

Mounjaro’s side effects include those of similar medications for type 2 diabetes. Common side effects encompass nausea, vomiting, diarrhea, and headaches, while more severe effects may include low blood sugar and abdominal or stomach problems.

What is Type 2 Diabetes?

Type 2 diabetes happens where the body struggles to regulate blood sugar levels properly. It happens when the body becomes resistant to insulin, a hormone that helps control blood sugar. As a result, blood sugar levels rise, potentially leading to various health issues. It’s often managed through diet, exercise, medications, and sometimes insulin injections. Mounjaro can possibly be a beneficial addition.

Is Mounjaro available in Australia?

Yes, it is now available in Australia in vial and Kwikpen form. In late 2022, Mounjaro received approval from the Therapeutic Goods Administration for treating adults with uncontrolled type 2 diabetes who cannot use metformin or require extra diabetes medication.

It is manufactured in various forms such as vials and pens, and comes in different strengths. The TGA approved the vial for injection in July 2023 and it was released in Australia in October in 2023. The Kwikpen was released in September 2024.

Does Mounjaro work for weight loss?

Its advantages have become evident since its introduction in the US market. Despite its primary focus on type 2 diabetes treatment, it has attracted interest for its potential benefit in weight management. In a 72-week clinical trial with overweight participants who received weekly Mounjaro injections, there were notable reductions in weight and improvements in blood sugar control.

It has recently been approved for weight loss due to its mechanism in suppressing appetite and which makes you feel full for longer. It reduces how much food is eaten and slows down how quickly food leaves the stomach.

The Cost of Mounjaro

The exact cost of Mounjaro in Australia varies based on the dose pen or vial, but it is likely to align with the pricing of other GLP-1 receptor agonist medicines which are not on the PBS. 

The alternatives to Mounjaro?

Individuals interested in beginning their journey with Mounjaro should consult a doctor about their options. It is important to have a detailed discussion with a healthcare professional to determine the right course of action.
