ABOUT THE MEDICATION
Mounjaro is the brand name for tirzepatide, a prescription-only injectable licensed for chronic weight management in eligible adults. It is a dual GLP-1 and GIP receptor agonist administered once weekly using a pre-filled pen.
tirzepatide
Acts on two gut-hormone pathways involved in appetite, fullness and blood-glucose regulation.
pre-filled pen
Treatment and dose escalation are managed by the prescribing clinician alongside dietary and lifestyle support.
Developed by Eli Lilly, Mounjaro was the first approved dual GLP-1/GIP receptor agonist for weight management in the UK. Treatment begins at a lower dose and is increased gradually under prescriber guidance as part of a supervised programme.
HOW IT WORKS
Mounjaro activates both GLP-1 and GIP receptors. These pathways are involved in appetite, satiety, stomach emptying and glucose control.
WHAT IT MAY SUPPORT
Individual responses vary. Treatment decisions, dose changes and monitoring must be managed by the prescribing healthcare professional.
CLINICAL ELIGIBILITY
Eligibility is decided by a registered healthcare professional after reviewing the person’s full clinical profile. BMI can be one consideration, but it is not the only factor.
The criteria above are a general overview. Only a registered prescriber can determine whether Mounjaro is appropriate for an individual.
PRESCRIPTION PROCESS
A registered prescriber must complete the clinical assessment and issue the prescription. Iris Health then verifies, dispenses and delivers it.
Consult a registered prescriber in person or through a properly regulated online service, providing relevant health information.
The prescriber reviews clinical suitability and, if appropriate, issues a prescription at the selected starting dose.
Our pharmacist confirms prescriber authority, patient details, dose and clinical appropriateness before dispensing.
Medication is packed in validated cold-chain packaging and dispatched with tracking and delivery updates.
UK HOME DELIVERY
Iris Health provides refrigerated, tracked delivery to eligible UK addresses. Every delivery uses validated temperature-controlled packaging appropriate to the medicine and transit time.
STORAGE GUIDANCE
Always follow the patient information leaflet supplied with your specific pen. The current storage instructions must be checked before use.
Storage instructions can be product-specific. If you are unsure whether the medicine has been stored correctly, contact the pharmacy before using it.
SAFETY & MONITORING
Gastrointestinal side effects are commonly reported, particularly when starting treatment or following a dose increase. Serious symptoms require prompt clinical advice.
The patient information leaflet is the authoritative source. Do not stop or change medication without guidance from the prescribing clinical team.
| Side effect | Reported frequency | General guidance |
|---|---|---|
| Nausea | Very common | Often more noticeable early in treatment; discuss concerns with the clinical team. |
| Diarrhoea | Very common | Speak to a pharmacist or prescriber if severe or persistent. |
| Vomiting | Common | Contact the clinical team if severe or affecting hydration. |
| Constipation | Common | Discuss persistent symptoms with the clinical team. |
| Injection-site reactions | Common | Follow administration guidance and discuss ongoing reactions. |
| Persistent severe abdominal pain | Seek advice promptly | Stop and obtain urgent medical advice, as advised in the patient leaflet. |
| Possible gallbladder symptoms | Seek advice promptly | Discuss relevant symptoms with the clinical team promptly. |
Regular clinical reviews are important throughout treatment. Tell your prescriber about new medicines, changes in health or plans for pregnancy.
