Mounjaro 101

What is Mounjaro?

Mounjaro is a brand-name version of the generic medication tirzepatide. Unlike its cousin Ozempic (semaglutide), Mounjaro is both a glucagon-like peptide 1 (GLP-1) receptor agonist and a glucose-dependent insulinotropic polypeptide (GIP) agonist.

Mounjaro is FDA-approved to improve blood sugar control in adults with type 2 diabetes, along with diet and exercise, but may be prescribed off-label to help with weight loss.

How does Mounjaro work?

Mounjaro acts like the GLP-1 and GIP hormones to lower blood sugar levels and decreases your appetite so you lose weight. It also slows down how fast food moves through your body, which may help you stay full for longer.

Do you prescribe Mounjaro for weight loss?

Mounjaro is not FDA-approved for weight loss and Ro currently does not offer Mounjaro through the Ro Body program. Mounjaro can help with weight because it mimics the action of two natural hormones, GLP-1 & GIP, to control blood sugar and appetite levels. It also slows digestion, allowing you to feel fuller longer, and decrease your appetite. These actions help you change your biological set point, allowing you to maintain a new, healthier weight.

What is Mounjaro’s dosing?

Like some of the other GLP-1 medications, Mounjaro dosing starts out low and then gradually increases. Mounjaro dosing typically starts at the lowest dose of 2.5 mg per week, and increases as appropriate with a maximum dose of 15 mg per week.

How do you take Mounjaro?

Mounjaro is administered via a single-use prefilled injection pen with the prescribed dose. You administer the injection under the skin of your stomach, thigh, or arm once a week.

Still have questions? We have answers.

There are no specific foods that you need to avoid when taking Mounjaro. However, some people taking Mounjaro experience gastrointestinal side effects, like nausea, until a steady dose is reached. For this reason, some people choose to avoid certain foods that may exacerbate their side effects.

Mounjaro comes with a risk of potential side effects. The most common side effects are often linked to a dose increase. Over time, these side effects improve once a steady dose is reached. 

Some of the most common side effects include:

  • Nausea 

  • Diarrhea

  • Decreased appetite

  • Vomiting 

  • Constipation

  • Indigestion

  • Stomach pain

More severe side effects are rarer, but possible. Serious side effects include:

  • Possible thyroid tumors and thyroid cancer—The FDA has issued its most serious warning (called a boxed warning) that Mounjaro may be associated with a type of thyroid cancer called medullary thyroid carcinoma. So far, this side effect has primarily been seen in laboratory studies using rodents, so the risk to humans has not been determined.

  • Pancreatitis

  • Low blood sugar

  • Severe allergy (hypersensitivity)

  • Kidney disease

  • Gastrointestinal disease

  • Vision problems (diabetic retinopathy)

  • Gallbladder disease

For full safety information, including boxed warning, see ISI.

You should keep Mounjaro in the refrigerator and store the pens in their original packaging to protect them from light. Do not freeze the Mounjaro pens.

If you are traveling, you can keep your Mounjaro unrefrigerated for up to 21 days. Just make sure the temperature does not get any higher than 86°F (30°C).

Mounjaro starts to work after you take your first dose, but it will likely take several weeks to months to see a change in your weight or blood sugar levels.

The short answer is yes you can switch GLP-1 drugs. However, each one has a different dose and dosing schedule so be sure to discuss this with your provider before making the change. Some people may experience more or different side effects when switching from one GLP-1 drug to another. And it will still take several weeks for the full effect of the new drug to take hold.
