People exploring prescription weight loss injections often compare Mounjaro and Wegovy when deciding which option may be right for them. Both treatments can support weight loss by improving appetite control, but they work slightly differently and may suit different needs, medical histories, and goals.
A clear comparison can help you understand what each medication does, how it is taken, and what to consider before starting treatment. It is also important to remember that eligibility and safety come first, and either option should be prescribed only after an appropriate clinical assessment.
At Newington Pharmacy in Edinburgh, we provide clear, evidence based guidance to help you understand your options and choose a safe, realistic approach to weight management.
What is Mounjaro?
Mounjaro is a prescription injection that affects hormones involved in appetite regulation and blood sugar control. It is taken once weekly using a pre filled injection pen. Many people report feeling fuller sooner, staying satisfied for longer, and finding it easier to reduce snacking and portion sizes.
Dosing is usually increased gradually over time. This helps the body adjust and can reduce the likelihood of side effects, particularly digestive symptoms.
What is Wegovy?
Wegovy is also a prescription once weekly injection used for weight management. It works by mimicking a hormone involved in appetite regulation, helping many people feel fuller, reduce cravings, and maintain a calorie controlled plan more comfortably.
Like Mounjaro, Wegovy is usually started at a lower dose and increased gradually. The goal is to balance results with tolerability and support long term consistency.
Mounjaro vs Wegovy: A Comparison

Which is More Effective for Weight Loss?
Effectiveness depends on the individual. Some people respond better to one medication than the other, and results vary based on starting weight, appetite response, and consistency with eating habits.
In general, both options can be effective when combined with a calorie controlled plan, adequate protein intake, and regular movement. Medication supports appetite control, but long term results usually come from sustainable routines.

Mounjaro and Wegovy Side Effects
The most common side effects with both medications are digestive. These may include nausea, constipation, diarrhoea, or a feeling of being overly full. Many people find symptoms improve over time, particularly when meals are smaller and hydration is prioritised.
Side effects are often more noticeable after dose increases. This is why gradual escalation and regular reviews are important, especially in the first few months of treatment.
Who May Be Eligible for Weight Loss Medication?
Eligibility is based on clinical criteria, including BMI and weight related health risks. A consultation is required to assess suitability, review medical history, and discuss whether treatment is appropriate and safe.
It is also important to consider current medications and health conditions. Both Mounjaro and Wegovy require professional oversight, and they are not suitable for everyone.
