Frequently asked questions

• How much weight can you lose using Wegovy®?

  Wegovy® is one of the most effective weight loss treatments available. When used alongside a modified diet and exercise, studies have shown over almost 85% of people achieved weight loss of 5% or more, 66% achieved weight loss of 10% or more, and almost 50% achieved weight loss of 15% or more.

• What BMI do I need to be to start treatment?

  Wegovy and Mounjaro treatments are recommended for adults with an initial BMI of 30 kg/m² or higher (classed as obese). They are also appropriate for people with a BMI between 27 kg/m² and 30 kg/m² (classed as overweight) if you also have weight-related health issues such as prediabetes, high blood pressure, sleep apnea, high cholesterol, or heart problems.

   

  For individuals from Asian, Black African, African-Caribbean, or Middle Eastern backgrounds, the thresholds for overweight and obese categories are reduced by 2.5 kg/m² to reflect their higher risk at lower BMIs.

   

  However, if an individual is transferring their treatment from another provider, they must still meet our eligibility criteria. If their BMI has fallen below the initial threshold required for treatment, we will be unable to prescribe the medication.

   

  Injectable weight loss treatment can be continued until you are in a healthy weight range (BMI equivalent of 25 or 23.5 if minority ethnic groups)

• Can I switch between Wegovy® and Mounjaro®?

  We would advise you to stay on the same type of injectable weight loss treatment. However, if you would like to switch, you should start from the lowest dose of the new treatment. For example a patient previously prescribed Wegovy, should always start on Mounjaro® 2.5mg. No “wash out” period is required between treatment types, so you can continue the following week with your new treatment.

• How do I inject the treatment?

  Mounjaro® and Wegovy® are once-weekly injections given in the arm, leg or abdomen. They use a very small, fine needle for a near-painless injection just below the surface of the skin. Both treatments come with clear instructions for use.

• What’s the difference between Wegovy® and Mounjaro®?

  Wegovy® and Mounjaro® are both self injection GLP-1 treatments that are used once a week. Wegovy® has the active ingredient semaglutide, whereas Mounjaro has the active ingredient tirzepatide.

  Mounjaro® is the more effective treatment and studies have shown patients to achieve up to 20% weight loss on the highest doses. This is versus the 15% average of Wegovy® and 7.5% average for Ozempic® which is solely indicated for type 2 diabetes
