What is Mounjaro?
Mounjaro (tirzepatide) is a prescription-only weight-loss medication available in the UK. It works by activating the body’s natural GLP-1 and GIP hormones, helping to reduce appetite, increase feelings of fullness, and support steady, sustainable weight loss when used alongside lifestyle changes.
Most patients experience reduced appetite and early weight loss within the first few months of treatment.
- Reduced appetite and cravings
- Supports long-term weight management
- May improve metabolic health
- Clinician-led, medically supervised treatment
Is Mounjaro safe?
Mounjaro (tirzepatide) has been extensively studied in clinical trials and approved by the UK’s MHRA. It is prescribed only after a clinical assessment to ensure it is safe and suitable for you. Your treatment is monitored throughout, with access to ongoing clinical support.
What are the common side effects?
The most common side effects are nausea, reduced appetite, vomiting, diarrhoea, or constipation, particularly when starting treatment or increasing the dose. These effects are usually mild to moderate and often improve as your body adjusts.
Who should not use Mounjaro?
Mounjaro may not be suitable if you are pregnant or breastfeeding, have a history of certain thyroid conditions, or specific gastrointestinal conditions. Your clinician will review your medical history carefully before prescribing.
How quickly does Mounjaro start working?
Many patients notice reduced appetite within the first few weeks. Weight loss typically occurs gradually over time and varies between individuals depending on dose, lifestyle, and adherence.
Is Mounjaro a long-term treatment?
Mounjaro is intended to support long-term weight management when used alongside lifestyle changes. Your clinician will regularly review your progress and adjust your treatment plan as needed.
How is Mounjaro taken?
Mounjaro is a once-weekly injection, taken on the same day each week. Full guidance is provided, and support is available if you have any questions about administration.
What support do I receive during treatment?
You’ll have access to ongoing clinician support, including 24/7 WhatsApp messaging, regular check-ins, and guidance on managing side effects, dosing, and lifestyle changes.
