Why Consider Switching Back to Mounjaro®?
There are several reasons why a patient may choose to switch back to Mounjaro® from Wegovy®:
Tolerability: your body may have managed Mounjaro®'s side effects more comfortably than Wegovy®'s.
Effectiveness: your appetite suppression or weight-loss progress may have felt more consistent on Mounjaro® than on Wegovy®.
Preference: you may prefer the Mounjaro® KwikPen® device, or Mounjaro®'s specific dosing experience.
A MedExpress clinician will always assess whether switching back to Mounjaro® is clinically appropriate for your individual situation.
How Do Wegovy® and Mounjaro® Compare?
Mounjaro® is often considered a more potent weight-loss treatment than Wegovy® due to its dual-hormone action (GIP and GLP-1), though individual responses vary.
Both Mounjaro® and Wegovy® are once-weekly self-injections provided in pen formats (Mounjaro® KwikPen® and Wegovy® FlexTouch®).
The most suitable medication for you depends on:
Your weight-loss progress
Any side effects you've experienced
Your overall treatment tolerance
Clinical assessment by a MedExpress prescriber
What Is the MedExpress Process for Switching Back to Mounjaro®?
Switching back to Mounjaro® from Wegovy® uses the same ordering process as any other MedExpress weight-loss consultation — there's no separate "switch" process to follow:
Go to the MedExpress website and click "Account and orders" (top right of the homepage), then log in.
Click "See all treatments" (top left of the homepage), then click "Mounjaro" under the Weight Loss category.
On the Mounjaro® Injectable Pen page, click "Check your eligibility" to start your consultation.
Complete the consultation questions and agree to the terms and conditions.
Choose your Mounjaro® dose and complete payment online (phone payments are not accepted).
Await clinical review: MedExpress's clinical team reviews every order, including checking for any change in medication. If your switch back to Mounjaro® is appropriate and safe, your order is approved; if not, the clinical team may email you with further questions, or decline the order.
This process is identical whether you're switching back to Mounjaro® or simply continuing with your current medication — it's MedExpress's clinical review that specifically checks for, and assesses, a medication change like switching from Wegovy® back to Mounjaro®.
How Is My Mounjaro® Starting Dose Determined When Switching Back?
The appropriate Mounjaro® starting dose depends on the Wegovy® dose you most recently completed and your overall tolerability.
In some cases, a MedExpress clinician may recommend starting at a lower Mounjaro® dose than your previous Wegovy® dose would suggest, to help ensure safety and tolerability. The final dosing decision is always made by MedExpress's clinical team.
Important Safety Considerations
Switching back to Mounjaro® is not automatic. MedExpress clinicians review your current and previous doses, how recently you took Wegovy®, any side effects you've experienced, and your medical history, to help ensure the switch is safe and appropriate for you.
