Mounjaro, Wegovy and Foundayo: Derry treatment guide
If you are comparing Mounjaro, Wegovy or Foundayo, this guide explains where each may fit. There is no single treatment that suits everyone: a safe plan starts with your health, medicines, circumstances and goals—not with choosing a product.
It does not recommend a particular treatment and cannot replace an individual clinical assessment. Booking a consultation does not guarantee a prescription.
The main treatment routes
Nutrition and everyday habits
A sustainable eating pattern, sleep, activity and practical routines form part of weight management whether or not another treatment is used.
Behavioural support
Structured goal-setting, identifying triggers and planning for setbacks can help people make changes that are realistic in daily life.
Prescription treatment
Several prescription options exist. Their benefits, risks, monitoring and suitability differ, and treatment must follow an individual assessment.
Specialist assessment
Some people may benefit from GP input, specialist weight-management services, psychological support, dietetic care or assessment for surgery.
Where prescription medicines fit
Prescription medicines are normally considered alongside changes to nutrition and physical activity, not as a replacement for them. The appropriate option depends on factors such as medical history, current medicines, weight-related conditions, pregnancy plans, previous treatment and the ability to attend monitoring.
A clinician should explain expected benefits, common and serious risks, how treatment is used, what follow-up is required and when it should be reviewed or stopped. A medicine that is appropriate for one person may be unsuitable for another.
Questions a clinical assessment should answer
- Is there an underlying health issue or medicine affecting weight?
- What outcome would be meaningful and realistic?
- Which options are clinically appropriate—and which should be avoided?
- What monitoring and follow-up will be needed?
- How will side effects or a lack of response be managed?
- What is the longer-term maintenance plan?

Look for a named, appropriately registered prescriber; a proper consultation; clear arrangements for monitoring and side effects; transparent contact details; and a regulated source of medicines. Avoid unregulated products advertised through social media or sellers who offer prescription treatment without an adequate assessment.
