It is not known if MOUNJARO is safe and effective for use in children under 18 years of age.

It is not known if MOUNJARO can be used in people who have had pancreatitis.

When not to use Mounjaro?

There are certain precautions where Mounjaro may not be suitable if:

  • You are allergic to tirzepatide or ingredients found in Mounjaro pen
  • You have problems with your pancreas or kidney
  • You have a history of diabetic retinopathy
  • You are pregnant or breastfeeding or plan to become pregnant or breastfeed
  • You or you family have had medullary thyroid carcinoma – MTC
  • You have Multiple Endocrine Neoplasia syndrome type 2 -MEN 2
  • You have severe problems with your stomach, such as slowed emptying of your stomach (gastroparesis) or problems digesting food
  • You are taking insulin or sulfonylureas
  • You take birth control pills by mouth? These may not work as well while using Mounjaro. Your healthcare provider may recommend another type of birth control when you start Mounjaro or when you increase your dose
  • You have type 1 diabetes

Active ingredient of Mounjaro and mechanism of action

Mounjaro is the first and only approved treatment in a different class of medication for type 2 diabetes. The active ingredient in Mounjaro is tirzepatide. Tirzepatide is a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonist. It is the first and only unimolecular dual GIP/GLP-1 receptor agonist. 

Both GIP and GLP-1 increase the production of insulin in your body. 

It has proven to result in significant reductions in A1c levels and body weight. Mounjaro works in several ways:

  • It increases insulin production, but only when your blood sugar is rising—which makes the risk of low blood sugar minimal
  • It decreases your liver’s production of sugar
  • It slows down the speed at which your stomach empties food into your intestine. This helps manage your blood sugars after eating while also leaving you feeling full longer

Is Mounjaro as effective as Ozempic? 

Mounjaro is more effective than Ozempic (semaglutide) for blood sugar control and weight loss. For people taking Mounjaro, 82% reached an A1C under 7% on the 5-mg dose, 86% reached an A1C under 7% on the 10-mg dose, and 86% reached an A1C under 7% on the 15-mg dose. For people taking Ozempic 1-mg, 79% reached an A1C under 7%.

The American Diabetes Association (ADA) recommends that a reasonable goal for most adults with type 2 diabetes is an HbA1C less than 7%. 

Does Mounjaro reduce cardiovascular risks?

It is not yet proven, however there may be a follow-through assumption of the Novo Nordisk Phase III SELECT trial of Wegovy (semaglutide) which showed a statistically significant reduction in major adverse cardiovascular events (MACE) of 20%. Eli Lilly is sponsoring the CVOT in obese patients, SURMOUNT-MMO, which is expected to yield data in 2027.  

Can Mounjaro be used for weight loss?

Mounjaro is not currently FDA approved for weight loss or chronic weight management, despite data that shows that there is significant weight loss associated with using Mounjaro.  

In June 2023 Eli Lilly presented data from the Phase III SURMOUNT-2 study at the American Diabetes Association meeting, which showed a mean weight loss of 13.4% among patients receiving the 10mg dose and 15.7% for the 15mg dose after 72 weeks in overweight and obese patients with type 2 diabetes.

In August 2023, Eli Lilly confirmed that it had applied to the US Food and Drug Administration for the approval of Mounjaro for chronic weight management.

Some physicians and doctors are currently prescribing Mounjaro for weight loss, off-licence. 


People taking mounjaro lost up to 25 pounds


‡Individual results may vary. In studies with or without other diabetes medications, weight loss in adults ranged from 12 lb (5 mg) to 25 lb (15 mg).

Can Mounjaro Pen be shared?

No. You should not share your Mounjaro pen with others, even if the needle is changed. You may give other people a serious infection or get a serious infection from them through cross-contamination.

Is it safe to use compounded Mounjaro?

The manufacturer has said that they do not sell Mounjaro or the active ingredient tirzepatide for compounding. Eli Lilly is the sole company that has FDA approval to market Mounjaro and it is supplied in a branded box that includes a proprietary pen along with FDA-approved prescribing information. Eli Lilly  cannot validate safety or effectiveness of products claiming to contain tirzepatide. Therefore, compounded Mounjaro should be avoided. While doctors can prescribe these medications “off-label” for obesity, insurance companies may deny these claims.

Is there a shortage of Mounjaro?

Mounjaro, in all strengths, is available to community pharmacies nationwide for treatment in patients with type 2 diabetes. There may be normal delays given the time required to order the product from their local distribution center, and geographical variabilities. However, there are concerns about supply effects, in anticipation of the manufacturer confirming it will be looking to licence the product for chronic weight management.

Forms of Mounjaro

Mounjaro comes as a solution in a prefilled, single-dose injection pen with the following dosage strengths:

  • 2.5mg/0.5mL
  • 5mg/0.5mL
  • 7.5mg/0.5mL
  • 10mg/0.5mL
  • 12.5mg/0.5mL
  • 15mg/0.5mL

Storage requirements for Mounjaro

Mounjaro is temperature sensitive and should be handled as follows: 

  • Store your Pen in the refrigerator between 2C to 8C
  • You may store your Pen at room temperature below 30C for up to a total of 21 days
  • Do not freeze your Pen. If the Pen has been frozen, throw the Pen away and use a new Pen
  • Store your Pen in the original carton to protect your Pen from light
  • The Pen has glass parts. Handle it carefully. If you drop the Pen on a hard surface, do not use it. Use a new Pen for your injection
  • Keep your MOUNJARO Pen and all medicines out of the sight and reach of children

Dosage of Mounjaro

Mounjaro is given as a weekly injection under the skin (subcutaneous). It should be administered at the same time each week, at any time of the day. The 2.5-mg dose is for treatment initiation and is not intended for glycemic (blood sugar) control. 

Patients are initiated with the 2.5-mg dose once weekly.

After 4 weeks on the 2.5-mg dose, the physician may increase to the 5-mg dose once weekly. If additional glycemic control is needed, the physician can continue to increase the dose by 2.5-mg increments after at least 4 weeks on the current dose. The maximum dose is 15 mg once weekly.

Even though doses change, the administration frequency will always be weekly. It is important to follow the dosage instructions provided by your healthcare provider.

How long does it take for Mounjaro to start working?

Mounjaro starts working immediately. It achieves glycaemic control faster than other treatment. SURPASS-2 and SURPASS-3 studies have shown that those taking any dose of Mounjaro reached A1C targets about 4 weeks sooner than those using injected semaglutide (Ozempic) 1 mg. When compared to titrated insulin degludec (Tresiba), participants using Mounjaro achieved the A1C goals between 4 and 12 weeks sooner.


How do I use the Mounjaro Pen?

Follow these 4 steps to use your Mounjaro pen:

Step 1: Choose your injection site. Your healthcare provider can help you choose the injection site that is best for you. You or another person can inject the medicine in your stomach, thighs, or the back of your upper arms. Another person should give you the injection in the back of your upper arm.
