What is Mounjaro?

Mounjaro (pronounced mown-JAHR-OH) is a once-weekly injectable medication used to treat type 2 diabetes and support weight loss. Its active ingredient, tirzepatide, helps control blood sugar, suppress appetite, and reduce cravings. When combined with a healthy diet and regular exercise, Mounjaro can be an effective weight loss treatment for eligible individuals.

Who Can Use Mounjaro?

Mounjaro is recommended for adults who:
✔ Have a BMI of 30 or higher (classified as obese)
✔ Have a BMI of 27 or higher (overweight) and weight-related health conditions such as:

• Prediabetes
• High blood pressure
• High cholesterol
• Heart disease

Before using Mounjaro, it's important to consult a healthcare professional to check if it's the right option for you.

Do I Need a Prescription for Mounjaro?

Yes, Mounjaro is a prescription-only medication. You will need a prescription from a healthcare provider to use it for weight loss or diabetes management.

Learn more in our guide: Do You Need a Prescription for Mounjaro?.

How Does Mounjaro Work?

Mounjaro contains tirzepatide, which targets two hormones that control blood sugar and hunger (Nauck & D’Alessio, 2022):

1️⃣ GLP-1 (Glucagon-Like Peptide-1) – Helps reduce hunger and control blood sugar.
2️⃣ GIP (Glucose-Dependent Insulinotropic Polypeptide) – Supports blood sugar regulation and enhances appetite control.

How Mounjaro Supports Weight Loss:

✔ Regulates Blood Sugar – Helps stabilise glucose levels, reducing hunger and cravings.
✔ Suppresses Appetite – Mimics natural hormones that signal fullness.
✔ Slows Digestion – Helps you stay fuller for longer, reducing calorie intake.
✔ Boosts Energy Balance – Works with fat cells and the brain to support weight management.

Because Mounjaro works on two hormonal pathways, it has been shown to be more effective for weight loss than medications that target only GLP-1.

How effective is Mounjaro?

Mounjaro has been shown to be highly effective for weight loss when combined with lifestyle changes.

Key Results from Clinical Trials:

1. Up to 15.7% body weight loss in people with type 2 diabetes (Eli Lilly & Company, 2023).
2. Up to 20% weight loss over 18 months, one of the highest recorded for weight loss treatments (Singh, K.; 2024).
3. Non-diabetic individuals lost up to 22.5% of body weight in the SURMOUNT-1 trial (Jastreboff et al, 2022).

Optimising Results:

If you’re not seeing the desired results with Mounjaro, factors such as inconsistent use, lifestyle habits, or underlying health conditions might play a role. Learn more about potential barriers in the UK Meds guide: 'Why Am I Not Losing Weight on Mounjaro?'. Always consult your doctor to ensure Mounjaro is the right treatment for your individual needs.

How long does it take for Mounjaro to work?

Mounjaro starts working immediately, but visible changes in blood sugar control and appetite may take a few weeks. For best results, follow your doctor’s guidance and maintain a healthy diet and exercise routine.

For more information on this prescription medication patients should refer to the Mounjaro patient information leaflet.

Mounjaro users have varied experiences, as each person responds differently to this weight loss injection prescribed by their doctor.

Always consult your doctor, GP, or healthcare provider to determine if Mounjaro is the right weight loss treatment for your needs. If prescribed, you can assess its effectiveness based on your personal experience.

Here are some of the most commonly asked questions about Mounjaro (tirzepatide) for weight loss in the UK.

When Was Mounjaro Approved in the UK?

Mounjaro was approved by the MHRA (Medicines and Healthcare Products Regulatory Agency) on 8th November 2023 for weight loss and weight management in adults aged 18 and over.

For more details, check the MHRA announcement.

Is Mounjaro Available in the UK?

Yes, Mounjaro is available in the UK for private prescription as a weight loss and diabetes treatment. Since February 2024, adults aged 18 and over can purchase Mounjaro with a valid prescription.

Can I Get Mounjaro on the NHS?

As of October 2024, Mounjaro is not yet available on the NHS for weight loss. However, NICE (National Institute for Health and Care Excellence) is reviewing a phased rollout plan.

For now, Mounjaro is only available on a private prescription from providers such as UK Meds.

Does Mounjaro Come with Alcohol Swabs?

No, Mounjaro pens do not include alcohol swabs.

The manufacturer recommends cleaning the injection site with alcohol swabs before use. These can be purchased separately from a pharmacy or online.

Who Manufactures Mounjaro?

Mounjaro is made by Eli Lilly & Company, a global pharmaceutical company that also produces:

• Ozempic – for type 2 diabetes
• Wegovy & Saxenda – for weight loss

Is Mounjaro a GLP-1 Medication?

Yes. Mounjaro is a GLP-1 receptor agonist, meaning it mimics natural hormones in the body to:

• Control blood sugar
• Suppress appetite
• Support weight loss

Mounjaro also works on another hormone, GIP, which makes it more effective than other GLP-1 drugs like Wegovy.

Is Mounjaro the Same as Tirzepatide?

Yes. Mounjaro is the brand name, while tirzepatide is the active ingredient.

Can I Take Mounjaro If I Have High Blood Pressure?

Possibly. If you have high blood pressure, your doctor will assess your health history before prescribing Mounjaro.

Early research suggests Mounjaro may help lower blood pressure, but it is important to consult your doctor before starting treatment.

How Fast Will I Lose Weight with Mounjaro?

Clinical trials show that Mounjaro can help users lose up to 20% of their body weight over 72 weeks.

However, weight loss speed varies depending on:

• Your diet and exercise habits
• Your starting weight
• Your dosage and body’s response

For best results, Mounjaro should be combined with healthy lifestyle habits. If you are not seeing progress, see Why Am I Not Losing Weight on Mounjaro?.

Does Mounjaro Cause Fatigue?

Fatigue is not an officially listed side effect, but some users report feeling tired while using Mounjaro.

Possible reasons include:

• The body adjusting to lower calorie intake
• Fatigue being a common symptom of type 2 diabetes

If you experience persistent tiredness, consult your doctor.

Does Mounjaro Cause Erectile Dysfunction (ED)?

There is no evidence linking Mounjaro to ED.

If you experience erectile dysfunction while using Mounjaro, it is important to speak with your doctor to explore potential causes.

Does Mounjaro Cause Hair Loss?

Mounjaro does not directly cause hair loss. However, rapid weight loss can sometimes trigger temporary hair shedding (telogen effluvium).

To reduce hair loss:

• Ensure you get enough protein
• Take vitamin supplements if needed
• Avoid crash dieting

If hair loss persists, speak to your doctor.

If Mounjaro isn’t suitable for you, other weight loss medications include:

• Wegovy (semaglutide)
• Saxenda (liraglutide)
• Orlistat (including branded versions like Xenical and Alli)

Each works differently, and your healthcare provider can guide you in choosing the right treatment based on your health needs.
