How does Mounjaro (Tirzepatide) Work for Weight Loss: Side Effects, Cost



Mounjaro is a medication utilized to manage type 2 diabetes. Mounjaro aids in regulating blood sugar levels and is given through injection. It should not be used by people with type 1 diabetes or those who have had pancreatitis. The safety and effectiveness of Mounjaro in children who are under 18 have not been established.

Mounjaro injection is similar to other injectible medications such as Ozempic and Wegovy, but it differs in some aspects. Even though the FDA has not yet approved Mounjaro for weight loss, clinical trials have shown promising results for weight reduction in individuals with elevated body mass indexes.

What is Mounjaro?

Mounjaro is a medication that is administered through injection and is prescribed to adults who have type 2 diabetes mellitus. It is used in conjunction with regular exercise and a balanced diet to help regulate and improve blood sugar levels. People, who have a history of pancreatitis or those who have type 1 diabetes, should not use Mounjaro. It is available in six doses, 2.5mg, 5mg, 7.5mg, 10mg, 12.5, and 15mg1. 

How Mounjaro is Different from Ozempic and Wegovy?

Mounjaro is a new medication for diabetes that is different from other popular drugs like Ozempic and Wegovy. It works by activating two receptors at the same time: the GLP-1 receptor and the GIP receptor. This means it can help people lose weight better than drugs that only activate one receptor.

Mounjaro has not yet received FDA approval for weight loss, but it has shown promise in clinical trials for individuals without diabetes who have high body mass indexes (BMI). The FDA is fast-tracking its evaluation of Mounjaro due to these positive results.

How does Mounjaro Work?

Mounjaro is a new type of medication that works differently compared to drugs like Ozempic and Wegovy. Instead of being a single-receptor agonist, Mounjaro activates two receptors simultaneously, which is why it's called a "dual-agonist"1.

This unique approach has been shown to result in even greater weight loss for people using Mounjaro injections compared to those using single-agonist medications.

These receptors, called glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), stimulate hormones that help control blood sugar levels and reduce appetite, leading to weight loss4.

While Wegovy and Ozempic activate only the GLP-1 receptor, Mounjaro activates both the GLP-1 and GIP receptors1,6.

Is it true that Mounjaro lowers A1C with type 2 Diabetes?

Mounjaro has helped many people achieve an A1C level of less than 7% in multiple studies. The studies evaluated the effectiveness of 5-mg, 10-mg, and 15-mg doses of Mounjaro with participants initially having A1C levels between 7.9% and 8.6%. These studies were conducted for 40 and 52 weeks and showed consistent results across all doses of Mounjaro.

Does Mounjaro Good for Heart Health and Glycemic Control?

Clinical trials showed that Mounjaro is a good option for reducing weight, better glycemic index, and improving the cardiovascular system.

Eli Lilly is working on developing tirzepatide to treat various conditions such as type 2 diabetes mellitus (T2DM), obesity, cardiovascular disorders in T2DM, heart failure, non-alcoholic steatohepatitis, obstructive sleep apnea, and to help reduce mortality and morbidity in obesity6
