What is Mounjaro?
Mounjaro (tirzepatide) is a prescription-only weight loss injection that helps reduce appetite and support long-term weight management. It’s used alongside a healthy diet and lifestyle to help people with obesity or weight-related health conditions lose weight safely. Mounjaro contains tirzepatide, a type of medication known as a dual-acting hormone receptor agonist. It targets two natural hormones involved in blood sugar control and appetite regulation to help you feel fuller for longer and reduce food cravings. When taken consistently, Mounjaro can help you make sustainable lifestyle changes and maintain weight loss over time.
Who manufactures Mounjaro?
Mounjaro is manufactured by Eli Lilly and Company, a global healthcare firm that develops diabetes and obesity treatments. Eli Lilly holds the licence for tirzepatide and supplies Mounjaro across the UK under regulation by the Medicines and Healthcare products Regulatory Agency (MHRA). All Mounjaro pens dispensed by myBMI are sourced through approved, regulated supply chains that meet strict quality and safety standards.
How does tirzepatide work?
Tirzepatide helps your body feel full for longer and keeps blood sugar levels steady. It copies the effects of two natural hormones that control appetite and digestion – GLP-1 and GIP. Together, they help you eat less and stay satisfied after meals. By calming hunger signals and helping your body use food more efficiently, Mounjaro supports steady, healthy weight loss when used alongside a balanced diet and regular activity.

Once your consultation has been reviewed, your clinician will decide if treatment is right for you. If approved, they’ll issue a prescription. We will send your prescription to our partner pharmacy.

Ongoing Care
Your journey doesn’t end there. Our clinicians will continue to support you throughout your treatment, and you can check in any time through your account for advice. We’ll review your progress regularly and work with you to help you achieve results that last.

How effective is Mounjaro?
This medicine may help individuals lose up to 8% of their body fat in just 12 weeks. Research shows that, on average, people using this medicine lost 22% of their body weight over 72 weeks. For the best results, it should be used alongside a low-calorie diet and regular exercise.
How long does Mounjaro take to work?
The GIP & GLP-1 pen begins working right away, but it may take a few weeks to notice any changes. Most people see changes within 4-6 weeks, often experiencing reduced appetite and slight weight loss. More significant weight loss typically happens over 3-6 months.
The exact timeline for seeing results can vary. Factors like your starting weight, lifestyle, and how your body responds to the medication can play a role in this.
For more information on what you can expect from your Mounjaro pen, please read our guide here.
Will I regain weight after stopping?
You’re unlikely to regain weight if you maintain a healthy diet and exercise routine after stopping your GIP & GLP-1 pen. Ideally, the habits you’ve built will stick. However, if you reduce physical activity or consume more calories than you did while on the injection, some weight regain is likely.
Directions
Please read our in-depth guide here for more information on how to use your GIP & GLP-1 pen, including how to dispose of an empty pen and needles.
What if I’ve injected too much?
Taking more than your prescribed dose won’t make it more effective and can cause serious side effects.
If you’ve accidentally injected too much, seek medical help immediately. Overdose symptoms may include severe nausea, vomiting and low blood sugar (hypoglycemia).
Storing your Mounjaro pen
You must keep your medicine out of sight and reach of children.
Do not use this medicine after the expiry date which is stated on the pen label and on the carton after ‘EXP’. The expiry date refers to the last day of that month.
Store in a refrigerator between 2°C–8°C. Do not freeze the pen. Store it in the original packaging to protect it from light. Your GIP & GLP-1 pen can be stored unrefrigerated below 30°C for up to 21 days, and then the pen must be discarded.
