Wegovy vs Mounjaro – Which Weight Loss Injection Should You Buy?

Why People Are Comparing Wegovy and Mounjaro

With the growing demand for weight-loss injections, two names keep coming up: Wegovy (semaglutide, also known as Ozempic when used for diabetes) and Mounjaro (tirzepatide). Both are highly effective, but recent price changes have made patients carefully consider which one to buy. From 1st September 2025, Mounjaro’s private price in the UK will rise by up to 170%, making Wegovy a more affordable option for many.

What Is Wegovy (Semaglutide / Ozempic)?

Wegovy is a once-weekly injection containing semaglutide, the same active ingredient in Ozempic. The difference is that Wegovy is licensed in the UK specifically for weight management, not just diabetes. It works by mimicking a natural hormone that reduces appetite, slows digestion, and lowers calorie intake. Clinical trials have shown that Wegovy can help patients lose around 15% of their body weight on average when combined with lifestyle changes.

What Is Mounjaro (Tirzepatide)?

Mounjaro is a newer treatment containing tirzepatide, which works on two hormones (GLP-1 and GIP) rather than one. This dual action may give stronger results, with clinical studies showing weight loss of up to 20% of body weight for some patients. However, in the UK it is currently only available privately, and NHS access is very limited.

Effectiveness – Wegovy vs Mounjaro

• Wegovy (semaglutide/Ozempic): Up to 15% average weight loss.
• Mounjaro (tirzepatide): Up to 20% average weight loss.

Side Effects to Consider

Both Wegovy and Mounjaro share common side effects, especially when starting treatment:

• Nausea

  These usually improve over time as the body adjusts.
