Mounjaro (tirzepatide), a breakthrough drug for the treatment of Type 2 diabetes. The active substance in Mounjaro is tirzepatide, which acts in the same way as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Tirzepatide is the first and only GIP and GLP-1 agonist Approved for Type 2 diabetes.

What’s all the buzz about? Understanding the hype around Mounjaro let’s break it down:

Mounjaro (tirzepatide) 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg per 0.5 mL injection, is a prescription medicine for adults with type 2 diabetes used along with diet and exercise to improve blood sugar (glucose). It is not known if Mounjaro can be used in people who have had pancreatitis. Mounjaro is not for use in people with type 1 diabetes. It is not known if Mounjaro is safe and effective for use in children under 18 years of age.

What is Mounjaro used for?

Mounjaro is used along with exercise and a balanced diet to help manage blood sugar levels in adults with type 2 diabetes.

Type 2 diabetes is a condition that causes high blood sugar. Having high blood sugar levels over time can raise your risk of other conditions, such as heart attack, kidney problems, vision problems, or nerve conditions. It’s important to manage your blood sugar levels to lower your risk of these conditions.

Symptoms of type 2 diabetes may include:

  • feeling thirsty

  • urinating more often than usual

  • fatigue

  • blurry vision

  • wounds that are slow to heal

Mounjaro treats type 2 diabetes by lowering your blood sugar. It does this in multiple ways:

  • by helping your body release more insulin (a hormone that decreases your blood sugar levels)

  • by slowing sugar production in your liver

  • by slowing the emptying of food from your stomach, which can make you feel full for longer

Mounjaro has two limitations of use:

  • The drug isn’t approved for use in people with type 1 diabetes.

  • In people with pancreatitis (swelling and inflammation of the pancreas) or who have had this condition in the past, Mounjaro should not be used for treatment.

What are Mounjaro’s side effects?

Like most drugs, Mounjaro may cause mild or serious side effects. The lists that follow describe some of the more common side effects that Mounjaro may cause. These lists don’t include all possible side effects.

Keep in mind that side effects of a drug can depend on:

  • other health conditions you have

  • other medications you take

Your doctor or pharmacist can tell you more about the potential side effects of Mounjaro. They can also suggest ways to help reduce side effects.

Serious side effects

Serious side effects from Mounjaro can occur, but they aren’t common. If you have serious side effects from Mounjaro, call your doctor right away.

Serious side effects of Mounjaro that have been reported include:

  • pancreatitis (swelling and inflammation of the pancreas)

  • gallbladder problems

  • hypoglycemia (low blood sugar)

  • severe digestive side effects, such as severe nausea, vomiting, or diarrhea, which may lead to dehydration and kidney problems

  • boxed warning: risk of thyroid cancer

Conclusion:

Mounjaro (tirzepatide) marks a significant advancement in the treatment of type 2 diabetes, offering a dual-action approach through GIP and GLP-1 receptor activity.
