How does Mounjaro work?

The active ingredient in Mounjaro is called tirzepatide. This weight loss injection medication acts on two hormonal receptors: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) (Nauck & D’Alessio, 2022). These hormones help regulate blood sugar levels, reduce hunger, and keep you feeling fuller for longer by slowing down stomach emptying.

How effective is Mounjaro?

A clinical trial reported by Ellie Lilly & Company (2023) found that tirzepatide, that active ingredient in Mounjaro weight loss injections, achieved up to 15.7% weight loss in adults with obesity or overweight and type 2 diabetes.

Further clinical trials have demonstrated that Mounjaro, when combined with healthy lifestyle changes, can lead to significant weight loss of at least 20% over 18 months (Singh, K.; 2024). This effectiveness is attributed to its active ingredient, tirzepatide, which regulates blood sugar levels and manages appetite, offering a promising solution for weight management when combined with a health lifestyle change.

When should you use Mounjaro?

Mounjaro is recommended for individuals with a BMI (Body Mass Index) over 30 (classified as obese) or over 27 (classified as overweight) who also have weight-related health problems such as prediabetes, high blood pressure, high cholesterol, or heart problems (GOV.UK, 2024). It's important to consult with a healthcare provider to determine if Mounjaro is suitable for you and to ensure proper usage and monitoring.

How is Mounjaro taken?

Mounjaro is administered as a weekly self-injectable pen, adjusting the dose knob as instructed by your doctor. You inject it under the skin (subcutaneously) in areas such as your stomach, thigh, or upper arm (Mounjaro, 2024). The dosage starts low and gradually increases until you reach the maintenance dose prescribed by your healthcare provider. It's essential to follow the dosage instructions provided by your healthcare provider and to rotate the Mounjaro weight loss injection sites regularly.

Read UK Meds simple step-by-step guide for how to take Mounjaro.

Mounjaro manufacturer, Eli Lilly and Company, has created a helpful video to explain instructions for taking the weight loss injection. You can watch it below:

Where should I inject Mounjaro into my body?

The best places to inject Mounjaro are areas with more fat, such as your tummy (ensuring to inject more than 5cm away from your belly button), the front of your thighs, or your upper arms. It's crucial to change injection sites regularly, even if you inject in the same area, to avoid discomfort or skin issues (Drugs.com, 2023).

What is the typical Mounjaro dosage for weight loss?

It is important that you only ever use the dosage of Mounjaro that you have been told to use by your healthcare provider. This will ensure that you are remaining safe whilst using the medication. Typically, your healthcare professionals will prescribe the lowest dosage of Mounjaro that provides the desired effect (Eisenstein, C.; 2023).

Below is a table that outlines how much Mounjaro is typically used:

Mounjaro Dose Schedule
WeeksDoseNotes
1-42.5 mg once weeklyInitial dose for titration
5-85 mg once weeklyAssess tolerance before increase
9-127.5 mg once weeklyMonitor blood sugar levels
13-1610 mg once weeklyMonitor for efficacy and tolerability
17-2012.5 mg once weeklyFurther increase based on clinical response
21 onwards15 mg once weeklyMaintenance dose if well tolerated

What should you do if you miss a dose of Mounjaro?

Always consult your doctor if you have missed a dose of Mounjaro for appropriate advice. Typically, if you miss a dose of Mounjaro, you should take the missed dose as soon as possible within the following 4 days (96 hours) after the missed dose. If it has been more than 4 days since the missed dose window, skip the missed dose and take the next dose on the next regularly scheduled day. You should not take 2 doses of Mounjaro (tirzepatide injection) within 3 days of each other (Mounjaro, 2024).

How long does 1 Mounjaro pen usually last?

Mounjaro can last for up to 21 days if it is unrefrigerated, as long as the external temperature does not go above 30°C; it is advised to keep your pen in the original packaging to protect it from light (Mounjaro, 2024).

Each Mounjaro pen contains 4 doses and because it is a weekly dosage one pen should last for 4 weeks.

Who is Mounjaro suitable for?

Mounjaro is suitable for adults aged 18 and over with a BMI over 30 (classified as obese) or over 27 (classified as overweight) who also have weight-related health problems such as prediabetes, high blood pressure, high cholesterol, or heart problems (GOV.UK, 2023). 

Who is Mounjaro not suitable for?

Mounjaro is not suitable for individuals who are pregnant or breastfeeding, as well as those with certain medical conditions such as severe problems with digesting food, a history of pancreatitis, thyroid cancer, or allergies to tirzepatide or any of its ingredients (Weiser, P; 2023). It may not be suitable for individuals using certain other diabetes medications (Watson, A; 2023). It's crucial to consult with a healthcare provider to determine if Mounjaro is safe and appropriate for you based on your medical history and current health status.

Can you use Mounjaro if you are pregnant?

No, your doctor will likely recommend not using Mounjaro (tirzepatide) if you are pregnant because it’s not currently known if it is safe to use during pregnancy (Weiser, P; 2023). It's important to discontinue the use of Mounjaro at least one month before attempting to become pregnant. If you are pregnant or planning to become pregnant, it's essential to discuss your options with a healthcare provider to ensure the safety of both you and your baby.

Can you use Mounjaro if you are breastfeeding?

The safety of using Mounjaro while breastfeeding has not been established, it’s currently unknown if tirzepatide can be passed through to the newborn/infant in breastmilk so there could be a potential safety risk. Therefore, it is essential to consult with a healthcare provider before using Mounjaro if you are breastfeeding (EMC, 2024). They can provide guidance based on your individual circumstances and help you make an informed decision regarding the use of Mounjaro while breastfeeding.

Are there interactions between Mounjaro and other medications?

Yes, there can be interactions between Mounjaro and other medications, you can check what these medications are at Drugs.com. It's crucial to inform your healthcare provider about all the medications, supplements, and herbal products you are currently taking before starting Mounjaro. This includes both prescription and over-the-counter medications. Your healthcare provider can then assess potential interactions and adjust your treatment plan accordingly to ensure your safety and optimise the effectiveness of your medications.

What are the potential side effects of Mounjaro?

As with all other medications, some users may experience Mounjaro side effects when they are using the weight loss treatment (WebMD, 2024). There are some side effects that are more common than others. The most common side effects of Mounjaro include:

  • Nausea
  • Vomiting
  • Diarrhoea
  • Constipation
  • Fatigue
  • Lightheadedness
  • Flatulence
  • Gallstones

If you are concerned about any side effects you are experiencing with Mounjaro then it is recommended that you consult with your healthcare provider for advice.

What warnings does Mounjaro come with?

Mounjaro comes with a few warnings you need to know about. It has a boxed warning about the increased risk of developing thyroid cancer as demonstrated in clinical studies (Lilly, 2023). It is important to fully read the additional information in the patient information leaflet provided with the medication before you use it. You may need to speak to your doctor if you have severe problems with food digestion, a history of pancreatitis, diabetic eye problems, or if you are using other diabetes medications like sulphonylureas or insulin, as it may increase the risk of low blood sugar. When you first start using Mounjaro, you will need to keep an eye out for signs of dehydration. 

What alternative weight loss medications are there?

Alternative weight loss medications for Mounjaro include Wegovy (semaglutide) and Saxenda (liraglutide). These medications offer different mechanisms of action and may be prescribed based on individual patient factors and preferences. It's important to discuss with your healthcare provider to determine the most suitable option for your specific needs and health condition.

What alternative diabetes pen treatments are there?

Alternative diabetes treatment pens include Ozempic (semaglutide) injection pen. The diabetes treatment your doctor recommends will be prescribed on your individual circumstances to ensure that it is the safest and most appropriate treatment for you. 

What is the difference between Mounjaro and Saxenda?

Mounjaro and Saxenda are both weight-loss medications, but they have differences in their active ingredients and mechanisms of action (Drugs.com). Mounjaro contains tirzepatide, which works by regulating high and low blood sugar levels and curbing appetite through hormonal receptors. On the other hand, Saxenda contains liraglutide, which also acts on hormonal receptors to reduce appetite and promote weight loss. Additionally, the dosing frequency and administration method may vary between the two medications.

What is the difference between Mounjaro and Wegovy?

Mounjaro and Wegovy are both medications used for weight loss, but they have differences in their active ingredients (Drugs.com). Mounjaro contains tirzepatide, which regulates blood sugar levels and manages appetite. Wegovy, on the other hand, contains semaglutide, which also acts on hormonal receptors to reduce appetite and promote weight loss. 

What is the difference between Mounjaro and Ozempic?

Mounjaro and Ozempic are both medications that can be used to help manage type 2 diabetes (Drugs.com). While both medications have been shown to be effective in clinical trials, individual responses may vary, so it's important to consult with a healthcare provider to determine the most suitable option based on individual needs and medical history. In some countries, Ozempic can be used as a weight loss medication, however, this is not the case in the UK.

Does Mounjaro require a prescription?

Yes, Mounjaro requires a valid prescription from a healthcare provider (Medical News Today, 2024). It is a prescription medication used for weight loss and management.

Both medications belong to the class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs). Mounjaro is a weight loss medication, where as Ozempic is used for the treatment of type 2 diabetes.

However, they have different active ingredients and formulations.

Is Mounjaro the same as Wegovy?

No, Mounjaro and Wegovy are not the same medications, although they are both used for weight loss. Mounjaro contains tirzepatide, while Wegovy contains semaglutide. Both medications belong to the class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and help to manage appetite and promote weight loss. However, they have different active ingredients and formulations.

Can you switch from Ozempic to Mounjaro?

Switching from Ozempic to Mounjaro is possible and safe but should only be done under the guidance and supervision of your doctor (Verywell Health, 2023). As Ozempic is not licensed to help people lose weight in the UK, you should consult with your healthcare provider for further advice. Your healthcare provider can assess your individual health status, medication history, and treatment goals to determine if switching from Ozempic to Mounjaro is appropriate for you. 

Who makes Mounjaro?

The Mounjaro pen is manufactured by Eli Lilly and Company (Lilly, 2024). They are a pharmaceutical company known for developing various medications for a range of health conditions, including diabetes and weight management. They are a similar company to Novo Nordisk, the manufacturer of popular injection treatments for diabetes (Ozempic) and weight loss (Wegovy & Saxenda).

Is Mounjaro a GLP-1?

Yes, Mounjaro is a GLP-1 (glucagon-like peptide-1) receptor agonist (Diabetes UK, 2024). It contains tirzepatide, which acts as a GLP-1 receptor agonist to regulate high and low blood sugar levels, reduce appetite, and promote weight loss. This mechanism of action is similar to other medications in the GLP 1 receptor agonist class such as Wegovy, which are commonly used for the management of type 2 diabetes and weight loss.

Is Mounjaro and tirzepatide the same thing?

Yes, Mounjaro and tirzepatide are the same thing. Mounjaro is the brand name of the GLP 1 medication, while tirzepatide is the active ingredient in Mounjaro (EMA, 2024). It's common for medications to have both a brand name and a generic or active ingredient name.

Can you take Mounjaro if you have high blood pressure?

Clinical studies, funded by Eli Lilly and Company, are currently ongoing to assess if Mounjaro affects cardiovascular conditions; early indications suggest that it can significantly lower blood pressure (Medical News Today, 2024). Whether you can take Mounjaro if you have high blood pressure depends on your individual health status and the recommendation of your healthcare provider. Mounjaro is indicated for adults with a BMI over 30 (classified as obese) or over 27 (classified as overweight) who also have body weight-related health problems such as prediabetes, high blood pressure, high cholesterol, or heart problems.

How quickly do you lose weight with Mounjaro?

The rate at which individuals lose weight with Mounjaro can vary significantly depending on factors such as diet, exercise, dosage, and individual response to the medication. Clinical trials have shown that patients could achieve at least 20% weight loss after using the Mounjaro active ingredient tirzepatide for 72 weeks when combined with healthy lifestyle changes (Velazquez, A.; 2023). Results with Mounjaro will vary from person to person, however, it is viewed as an effective weight loss medication.

Does Mounjaro make you tired?

Whilst fatigue is not listed as a potential side effect of Mounjaro by the manufacturer, Eli Lilly and Company, some Mounjaro user reviews do complain of fatigue after using the medication (Drugs.com, 2023). Additionally, fatigue can be a common side effect associated with type-2 diabetes (Kalra & Sahay, 2018). While not everyone will experience fatigue while taking the medication, it is one of the possible adverse effects. If you notice excessive tiredness or any other concerning symptoms while taking Mounjaro, it's important to discuss them with your healthcare provider. They can evaluate your symptoms and provide guidance on how to manage them effectively.

Does Mounjaro cause erectile dysfunction?

It is not currently known if the active ingredient in Mounjaro, tirzepatide, can cause the sexual health condition, erectile dysfunction (ED), further research is needed in this area to determine if erectile dysfunction could be a potential side effect tirzepatide (Cherney, 2024).

Does Mounjaro cause hair loss?

No. Evidence suggests that Mounjaro does not directly cause hair loss (alopecia). In most instances, hair loss when taking the tirzepatide weight loss injections is more likely to be due to the stress of rapid weight loss on your body (Anderson, L.; 2024).
