Why Do I Need a New Consultation to Switch from Mounjaro® to Wegovy®?
Even though Mounjaro® and Wegovy® are both used for weight loss, they contain different active ingredients — Mounjaro® contains tirzepatide, and Wegovy® contains semaglutide — and follow different dosing scales. A new consultation allows MedExpress's clinical team to:
Review your history: MedExpress looks at your current Mounjaro® dose and how long you have been taking it.
Assess tolerability: MedExpress checks for any side effects you experienced on Mounjaro® to ensure Wegovy® is a good fit for you.
Ensure safety: MedExpress verifies that your health profile remains suitable for GLP-1 medication.
What Information Do I Need to Provide?
During your switching consultation, MedExpress will ask you to confirm:
Your current Mounjaro® dose, and how long you've been taking it
Any side effects you experienced while taking Mounjaro®
Any changes to your health profile since your last MedExpress consultation
This information allows MedExpress's clinical team to assess your suitability for Wegovy® and choose an appropriate starting dose.
What Is the MedExpress Process for Switching from Mounjaro® to Wegovy®?
Switching from Mounjaro® to 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 "Wegovy" under the Weight Loss category.
On the Wegovy® product page, click "Check your eligibility" to start your consultation.
Complete the consultation questions and agree to the terms and conditions.
Choose your Wegovy® 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 from Mounjaro® to Wegovy® is appropriate and safe, your order is approved; if not, the clinical team may email you with further questions, or decline the order.
How Is My Wegovy® Starting Dose Determined?
The goal of your switching consultation is to provide a safe and smooth transition from Mounjaro® to Wegovy®. Based on your consultation, MedExpress's clinicians will recommend the most appropriate Wegovy® starting dose for you, rather than automatically starting you at the lowest possible dose (0.25mg).
MedExpress aims to match your new treatment as closely as possible to your current level of progress and tolerance on Mounjaro®. This helps you maintain your weight loss momentum while minimising the risk of new digestive side effects. If your switch is approved, you can begin Wegovy® seven days after your final Mounjaro® dose.
