Switching from Mounjaro to Wegovy

Medicspot is now able to offer existing patients the option of switching from Mounjaro (tirzepatide) to Wegovy (semaglutide). After the recent Mounjaro price increase, Wegovy is now a more cost-effective medication than Mounjaro.

Like Mounjaro, Wegovy is a weekly self-injected GLP-1 medication which helps you feel fuller for longer. Like Mounjaro, each Wegovy pen contains 4 doses (a 4 week supply).

In clinical trials, Wegovy has been shown to help patients lose up to 15% of their bodyweight.

General dosage guide for switching

Wegovy comes in various doses. Patients can choose to:

  1. start from the lowest dose (0.25mg) to see how they respond to the medication
  2. request to start from a higher dose (if you have already been taking a higher dose of Mounjaro).

Please note: the prescribing clinician will determine which dose (if any) is the most suitable for your treatment. Requesting a specific dose does not guarantee that it will be prescribed.

Please see the chart below to understand which doses of Wegovy may be suitable when switching from Mounjaro. Find your current Mounjaro dose on the left hand side and read across the row. You may be eligible for any Wegovy doses in green, but you will not be eligible for any Wegovy doses in red.

For example, a patient currently taking the 15mg Mounjaro dose may be eligible to switch to the 0.25mg, 0.5mg, 1.0mg or 1.7mg dose of Wegovy  – but not the 2.4mg dose.

0.25mg = £149 (4 week supply)
