Mounjaro, Tirzepatide, and Why Both Names Matter
Brand names and medical (generic) names refer to the same medicine but appear in different contexts. Mounjaro is the brand name given by the manufacturer; tirzepatide is the international non-proprietary name (INN) — the standardised scientific name used in prescriptions, clinical literature, and official medicines information worldwide.
What tirzepatide actually is
Tirzepatide is a once-weekly injectable medicine that acts on two appetite-regulating pathways in the body: it is a dual GIP and GLP-1 receptor agonist. This dual action is what distinguishes it from older GLP-1 medicines. Many people experience a reduced sense of hunger and an increased feeling of fullness — though individual responses vary, and your prescriber or doctor is best placed to explain what to expect for your specific situation.
How this compares to Wegovy
If you have also come across the term medical name for Wegovy, that medicine's active substance is semaglutide — a GLP-1 receptor agonist. Unlike tirzepatide, semaglutide acts on the GLP-1 pathway only. You can read more on our Wegovy overview page. Both tirzepatide and semaglutide are prescription-only medicines; suitability for either is a decision made by a prescriber, not something to determine independently.
Where you will see the name tirzepatide
- On your prescription or dispensing label
- In the patient information leaflet inside your pen box
- In official medicines databases such as the electronic Medicines Compendium (eMC)
- In conversations with your prescriber, pharmacist, or healthcare professional

Keeping Track of Your Tirzepatide Journey with GLP Trackr
Knowing your medicine's active substance name is one small part of staying informed on your journey. GLP Trackr is a companion app built specifically for people already prescribed Mounjaro (tirzepatide) or Wegovy (semaglutide), and it brings together the information that matters most in one place.
The most relevant feature for day-to-day use is dose and injection logging — every dose strength, date, and injection site recorded so you always have an accurate record of your treatment. This log can be genuinely useful to bring to appointments with your prescriber or doctor, especially when discussing how your titration is progressing. The app's doctor report feature lets you share a clear summary of your journey, which can make those conversations more productive.
Alongside that, GLP Trackr's side-effect tracker lets you note how you are feeling after each dose and spot patterns over time — something many people find helpful when tirzepatide is new and responses are still settling.
GLP Trackr does not offer medical or dosing advice, and any questions about your prescription — including dose changes or concerns about how the medicine is working — should always go to your prescriber or doctor. The app is there to help you record and understand your own data, not to replace clinical guidance.
