The short answer

Mounjaro contains tirzepatide and Wegovy contains semaglutide. Both are prescription-only weekly injections for eligible adults, but they work differently and have distinct safety considerations. An assessment is needed to decide whether either is appropriate.

Question 1

How are Mounjaro and Wegovy different?

The active ingredients and hormone pathways differ. That can affect suitability, side-effect discussions and practical advice. A comparison table can explain facts, but it cannot determine what is safe for one person.

Question 2

What do they have in common?

Both are prescription-only weekly injections used alongside diet and activity changes. Both can cause gastrointestinal side effects and both require a prescriber to review your health and medicines.

Question 3

What should guide the decision?

The decision considers your medical history, current medicines, previous treatment, preferences, pregnancy plans and ability to attend reviews. Price or online popularity should not decide a clinical choice.

Question 4

Why discuss the comparison face to face?

A pharmacist can explain the differences in plain language, identify safety issues and set realistic expectations. If neither route is suitable, you should leave with a clear next step rather than an online rejection screen.
