Thinking about switching weight loss treatment? Programme costs can vary depending on the treatment recommended following clinical assessment. If switching is considered appropriate, your clinician will review your current programme and may discuss alternative treatment options.

*Illustrative examples only. Actual treatment, dosing, and programme costs are determined following individual clinical assessment and may differ from those shown.
Switching to a different weight loss treatment may affect your treatment costs. Your clinician will also consider your medical history, existing treatment plan, and whether you’ve experienced any side effects so far to determine if you’re a good candidate for switching.
Most patients don’t need to start the treatment again or take an extended break when switching. Your clinical team will give you all the support you need to transition to an alternative treatment if you and your clinician decide this may be appropriate for you.
