. Introduction – A Tale of Two Brands
The rise of GLP-1 medications has reshaped treatment for type 2 diabetes and obesity. Two top contenders are Ozempic (semaglutide) and Mounjaro (tirzepatide). But which one is the better choice? We compare their effectiveness, side‑effect profiles, pricing, and suitability for weight loss or diabetes management in the UK.
2. Active Ingredients & Mechanisms
| Drug | Active Ingredient | Receptor Action |
|---|---|---|
| Ozempic | Semaglutide | GLP‑1 agonist |
| Mounjaro | Tirzepatide | Dual-agonist: GLP‑1 + GIP |
- Ozempic targets the GLP-1 receptor, which controls appetite and insulin release.
- Mounjaro adds GIP receptor activation, offering enhanced metabolic benefits and appetite suppression.

3. Efficacy Comparison – What Clinical Trials Show
🔹 Weight Loss Results
- Ozempic: 10–15% body weight loss over 6–12 months
- Mounjaro: 15–22% average weight loss in the SURMOUNT trials (even higher at top doses)
🔹 Blood Sugar Control
- Ozempic: A1C drop of ~1.5%
- Mounjaro: Combined A1C and body weight reduction, with up to 2.5% decrease

4. Side Effects – Knowing What to Expect
| Side Effect | Ozempic | Mounjaro |
|---|---|---|
| Nausea | Common | Common |
| Diarrhoea | Yes | Yes |
| Fatigue | Mild | Mild to moderate |
| Dose-related issues | Lower | Higher incidence at top doses |
Both drugs share similar GI effects, but Mounjaro may produce more nausea during dose ramp-up due to its dual action—though many users report it is more manageable with time.
5. Dosage & Treatment Plans
- Ozempic: 0.5 mg → 1 mg (some now 2 mg weekly)
- Mounjaro: Start at 2.5 mg → up to 15 mg weekly
Mounjaro requires slower titration to avoid GI upset but offers greater dose flexibility.

- Mounjaro: Prescription required; available via private UK telehealth providers and pharmacies for both diabetes and weight loss
Bulk Mounjaro pens may offer savings, but NHS lists Ozempic as more accessible. Clinically, Mounjaro delivers higher value in weight-loss efficacy.
