Why consider switching back to Mounjaro®?
There are several reasons why a patient may choose to return to Mounjaro®:
Tolerability: Your body may have managed the side effects of Mounjaro® more comfortably.
Effectiveness: Appetite suppression or weight-loss progress may have felt more consistent on Mounjaro®.
Preference: You may prefer the Mounjaro® KwikPen® device or the specific dosing experience.
Clinical Review: A MedExpress clinician will always assess whether switching back to Mounjaro® is clinically appropriate for your individual situation.
Comparison of Wegovy® and Mounjaro®
While Mounjaro® is often considered a more potent weight-loss treatment due to its dual-hormone action (GIP and GLP-1), individual responses vary. Both are once-weekly self-injections provided in pen formats. The most suitable medication depends on:
Your weight-loss progress.
Side effects experienced.
Overall treatment tolerance.
Clinical assessment by a MedExpress prescriber.
How the process works
If you decide to switch back to Mounjaro®, the MedExpress process involves:
Log in to your account: Navigate to the weight-loss treatment section.
Complete a new consultation: Select Mounjaro® as your preferred treatment and provide accurate details about your recent Wegovy® use.
Select an eligible dose: Based on your previous Wegovy® history, the system may suggest an appropriate starting dose.
Submit and Pay: Complete payment online (please note: phone payments are not accepted).
Await Clinical Review: A prescriber will review your consultation and may contact you if further information is required before approval.
Dosage guidelines when switching
The appropriate starting dose depends on the Wegovy® dose you have most recently completed and your overall tolerability.
Example: If you have completed Wegovy® 2.4 mg, you may be eligible to start Mounjaro® at a higher dose (such as 12.5 mg) if clinically appropriate.
Safety First: In some cases, a clinician may recommend starting at a lower dose to ensure safety and tolerability. The final dosing decision is always made by the clinical team.
Important safety considerations
Switching is not automatic. MedExpress clinicians will review your current and previous doses, how recently you took Wegovy®, any side effects, and your medical history. This ensures the transition is safe and appropriate for your journey.
