Mounjaro Price Increase: Exploring the Best Options Now

Why the Mounjaro Price Increase Matters

From 1 September 2025, Eli Lilly, the manufacturer of Mounjaro, will increase the UK price of a one-month supply by up to 170%. Understandably, many patients are concerned about the impact on their treatment costs.

We want you to know we’re actively reviewing pricing, supply options, and alternative treatments to make sure patients can still access safe and effective weight loss care. For some, switching to Wegovy (semaglutide) or another GLP-1 treatment may be a better option — both for affordability and tolerability.

Mounjaro vs Wegovy: Understanding the Difference

Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are GLP-1 receptor agonists, a type of medicine that helps control appetite and slow digestion.

• Wegovy – Mimics GLP-1 only, leading to an average 16.7% weight loss over 2 years.

• Mounjaro – Mimics both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide), which can enhance results, with an average 22.9% weight loss.

While Mounjaro may offer greater weight loss for some, it can also bring stronger side effects — and now, significantly higher costs.

Can You Switch from Mounjaro to Wegovy?

Yes — but you can’t switch immediately. A one-week washout period is essential between your last Mounjaro dose and your first Wegovy injection. Our aim is to help you make the switch easily.

Safe Switching Process

1. Stop Mounjaro – Take your final dose as scheduled.

2. One-week break – Avoid all GLP-1 medicines during this time.

3. Start Wegovy at the lowest dose – Even if you were on a high Mounjaro dose, you must restart at 0.25mg and gradually increase.

4. Monitor your response – Watch for common side effects such as mild nausea or fatigue.

Overlapping the two treatments could increase risks such as severe nausea, vomiting, or more serious complications.

What to Expect After Switching

Many patients notice similar side effects between the two medicines. However, some find that symptoms like nausea improve on Wegovy.

Weight loss progress may vary, and it’s normal to experience plateaus. Staying consistent with healthy eating, physical activity, and lifestyle routines will help maintain long-term results.
