Comparing Mounjaro vs Wegovy

At some point the research stops being helpful. You have read the comparison articles, watched the explainers, looked up the trial data, and you are now in the position most people end up in: knowing roughly what Mounjaro and Wegovy are, having a general sense that Mounjaro produces stronger results on average, and still having no idea which one is actually right for you. The more you read, the more it feels like a decision that requires information you do not have.

That information exists. It is just not on a webpage. It is in your medical history, your current health, your blood pressure, your response to previous treatments if you have had any. A prescriber who can look at all of that and give you a direct answer is what you are actually looking for. Not more reading. Someone qualified to help you decide.

This guide covers how Mounjaro and Wegovy compare clinically, what the evidence actually shows, and how to get a face-to-face consultation with a GPhC-registered Independent Prescriber at Medihub Pharmacy in Swansea. It also includes an interactive tool below to help you think through which medication may suit your profile before you come in.

What Is the Difference Between Mounjaro and Wegovy?

Both Mounjaro and Wegovy are once-weekly injectable medications for weight management in adults. Both are prescription-only. Both work by influencing the hormonal signals that regulate appetite and digestion. The difference lies in how they do that, and how far the clinical evidence goes.

Mounjaro (Tirzepatide)

Mounjaro was approved by the MHRA for weight management in November 2023. Its active ingredient, tirzepatide, mimics two gut hormones simultaneously: GLP-1 and GIP. By activating both pathways at once, it slows gastric emptying, reduces appetite signals, and improves how the body handles blood sugar. No other weight loss injection currently licensed in the UK targets both pathways. That dual mechanism accounts for clinical trial results that exceed those of previously approved GLP-1 medications.

Treatment starts at 2.5mg weekly and escalates gradually through six dose tiers up to 15mg. The step-up approach minimises gastrointestinal side effects, which are most common in the early weeks. Your Medihub prescriber guides dose progression based on how you are responding, not on a fixed schedule.

Wegovy (Semaglutide)

Wegovy’s active ingredient is semaglutide, which mimics GLP-1 alone. It was approved in the UK for weight management before Mounjaro, giving it a longer post-approval record of real-world use. It slows gastric emptying, reduces appetite, and has a well-established clinical profile. For patients who have a health history that makes Mounjaro less appropriate, or who want to start with a medication that has more years of post-approval data, Wegovy is a clinically sound option.

Wegovy also follows a gradual dose escalation, starting low and increasing monthly toward the 2.4mg maintenance dose. Medihub offers Wegovy privately from £159 per month.

Side by Side

The numbers consistently favour Mounjaro on average weight loss. But a clinical trial average is not a prediction for any individual patient. Some people respond exceptionally well to semaglutide. For patients with type 2 diabetes, both medications have specific trial data, and the choice depends on the full health picture. For patients who have previously used a GLP-1 medication and did not tolerate it well, the prescriber needs to know that before recommending either option. Average results do not determine individual outcomes. A prescriber who knows your history does. For a broader view of the options available, see our guide to weight loss injections in Swansea.

Which One Is Right for You?

The tool below is not a diagnostic. It is a starting point to help you think through your profile before your consultation. Answer five questions and it will give you a general indication of which medication may suit you better. Your Medihub prescriber will confirm the right choice at your first appointment.

Pricing at Medihub Swansea

Both Mounjaro and Wegovy are available at Medihub across all licensed dose tiers. Every monthly price includes your face-to-face consultation, blood pressure check, and weight check. There are no additional charges for clinical monitoring.

Mounjaro Pricing

Wegovy Pricing

Wegovy at Medihub starts from £159 per month at the starting dose, rising to £239 at the maintenance dose. As with Mounjaro, every monthly price includes your face-to-face consultation, blood pressure check, and weight check. No additional charges.

The monthly price at Medihub is not just the cost of the medication. It covers clinical oversight from a qualified prescriber who has assessed you in person, knows your case, and reviews your progress every month. That standard of monitoring is not universal among private weight loss providers. At Medihub it is included as standard at every dose level for both medications.

Are You Eligible?

Eligibility is confirmed at your first consultation by your Medihub prescriber. As a general guide, the MHRA-approved criteria for each medication are:

Both medications are contraindicated in pregnancy and breastfeeding. Mounjaro should not be prescribed to anyone with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2. The MHRA also advises that Mounjaro may reduce the effectiveness of the oral contraceptive pill. Patients using the pill should use an additional method of contraception during treatment. Your prescriber will cover all contraindications at your first appointment.

Getting Started at Medihub Swansea

Medihub has two branches in Swansea. The Killay branch is on Gower Road (SA2 7BA), serving patients from Killay, Sketty, West Cross, Bishopston, Mumbles, and across the Gower Peninsula. The Pontarddulais branch is on St Teilo Street (SA4 8ST), covering Gorseinon, Llansamlet, Morriston, and the surrounding areas. Both branches prescribe both Mounjaro and Wegovy at the same prices.

At Killay, consultations are led by Osama Al-Saied, a GPhC-registered Independent Prescriber (GPhC number 2222112, publicly verifiable at pharmacyregulation.org). At Pontarddulais, patients are seen by Mr Carwyn Jones, who holds the same Independent Prescriber qualification. Independent Prescriber status allows your prescriber to independently assess, diagnose, and prescribe without GP involvement at any stage.

Your first appointment takes around 30 minutes.

Every month after that you return for a brief check-in: weight recorded, blood pressure taken, dose reviewed. These appointments are included in your monthly price. The Medihub Pharmacy GPhC registration is publicly verifiable: registration number 9012258.

Medihub also has a private waiting room at both branches. Consultations are unhurried and confidential. For more on Medihub's approach to weight loss treatment, see our weight loss clinic Swansea guide, and our full Mounjaro Swansea page for detailed information on tirzepatide specifically.
