What alternatives to Mounjaro exist?
Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist given as a once-weekly injection. The most frequently discussed prescription alternative is how Mounjaro works and what makes it distinct compared with other medicines in the same class — understanding the mechanism can help you have a more informed conversation with your prescriber.
Wegovy (semaglutide)
Wegovy contains semaglutide, a GLP-1 receptor agonist. Like Mounjaro, it is a prescription-only, once-weekly injectable medicine. It acts on GLP-1 pathways to support appetite regulation and feelings of fullness, but does not have the additional GIP receptor action that tirzepatide has. If you are considering a switch or wondering how the two compare, your prescriber is the right person to guide that conversation. You can also read more on alternatives to Wegovy if your circumstances change.
Other GLP-1 medicines
Other GLP-1 receptor agonists exist and may be prescribed in different clinical contexts — for example, some are used primarily in the management of type 2 diabetes. Whether any of these are appropriate for you depends on your diagnosis, health profile, and what your prescriber determines is suitable. No medicine in this class should be started, stopped, or switched without clinical guidance.
Non-injectable approaches
Some people ask about non-medication approaches alongside or instead of a GLP-1 medicine. Dietary changes, increased physical activity, and structured behavioural support are all elements that prescribers may recommend as part of a broader plan. These are not direct replacements for a prescribed medicine, and any changes to your treatment should be discussed with your healthcare professional.
For a side-by-side look at how tirzepatide and semaglutide compare on a factual level, the Wegovy to Mounjaro conversion chart covers dose equivalences that some people find useful context when speaking with their prescriber.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
Tracking your journey whichever medicine you are on
Whatever medicine your prescriber decides is right for you, staying consistent and informed throughout your treatment makes a real difference — and that is where GLP Trackr comes in.
The app's side-effect tracker is particularly useful during any transition period. If your prescriber moves you from one medicine to another, logging how you feel day to day — energy levels, nausea, appetite changes — gives you a clear, dated record to bring to your next appointment, rather than trying to recall weeks of experience from memory.
Beyond side effects, GLP Trackr also logs your weekly doses and injection sites, so your records stay accurate regardless of which medicine or pen you are using. The app supports both Mounjaro and Wegovy users, making it a consistent companion even if your prescription changes.
You can find a broader overview of tracking your Mounjaro journey — including dose logging, progress charts, and daily check-ins — in the Mounjaro hub.
Always follow the guidance of your prescriber or doctor when it comes to any decision about switching or changing your medicine — they know your full picture in a way no app can. If you experience anything severe or persistent during a change in treatment, contact your healthcare professional promptly.

Frequently asked questions.
Wegovy (semaglutide) is the most commonly discussed prescription alternative to Mounjaro (tirzepatide). Both are once-weekly injectable medicines that act on GLP-1 pathways, but they differ in mechanism. Which is appropriate for you is a decision for your prescriber or doctor.
Any decision to switch medicines must be made with your prescriber or doctor — never on your own. They will consider your health history, how you are responding to your current treatment, and what alternatives are suitable for your individual circumstances.
No. Wegovy contains semaglutide, a GLP-1 receptor agonist, while Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. They are distinct medicines with different active substances, though both are once-weekly injectables used in weight management under prescription.
Yes. GLP Trackr supports people on both Mounjaro and Wegovy, and can be used to log doses, injection sites, side effects, weight, and food regardless of which medicine you have been prescribed.
Some people ask about dietary, lifestyle, or other medical approaches. Whether any non-injection option is suitable depends on your clinical situation. Your prescriber or doctor is the right person to advise on what alternatives, if any, are appropriate for you.
