How Mounjaro Dosing Generally Works for Weight Loss
Mounjaro is a once-weekly injectable medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. It is prescribed as a prescription-only medicine for weight management, and the dose a person takes is always determined by their prescriber based on their individual circumstances.
Typical dose strengths
According to the electronic Medicines Compendium (eMC), Mounjaro is available in several dose strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. Treatment is typically started at the lowest strength, with your prescriber increasing the dose gradually over a number of weeks. This step-up approach is designed to help your body adjust and to manage the chance of side effects such as nausea.
Weight loss versus diabetes prescribing
Mounjaro is prescribed in different clinical contexts — including for weight management and for blood glucose control in type 2 diabetes. The dose strengths available are the same, but your prescriber decides the appropriate dose and schedule for your specific situation. If you have questions about why you have been prescribed a particular dose, or whether yours relates to weight loss or another condition, that conversation belongs with your prescriber or doctor.
Your dose is individual
There is no single "best" dose that applies to everyone. Factors such as how well you are tolerating the medicine, your progress, and your overall health all influence how your prescriber manages your dose over time. For a deeper look at what different dose stages involve, see choosing the right Mounjaro dose for weight loss or explore the Mounjaro dosing overview. If you are also curious about how dosing works with a different GLP-1 medicine, the semaglutide dose for weight loss page covers the equivalent information for Wegovy.

Tracking Your Mounjaro Doses with GLP Trackr
Staying consistent with a weekly injection schedule is one of the most important parts of a Mounjaro journey — and one of the easiest things to let slip. GLP Trackr's dose logging feature lets you record every injection: the date, the time, and the dose strength, all in one place.
Never lose track of where you are
With a once-weekly schedule, it can be surprisingly easy to lose track — especially when dose strength changes over time. Logging each shot in the app creates an accurate record you can refer back to, and gentle dose reminders mean a weekly injection is less likely to be forgotten entirely.
What to do if you miss a dose
If you miss a Mounjaro dose, the decision about what to do next belongs with your prescriber — do not attempt to double up or adjust your schedule without their guidance. What you can do is log the missed dose in GLP Trackr so you have an accurate record to discuss at your next appointment. For any concern about a missed injection, check the patient information leaflet that came with your pen, or contact your healthcare professional promptly. Your prescriber is always the right person to advise on this.
A record your prescriber can actually use
Over time, your dose log in GLP Trackr builds into a clear timeline of your treatment — which doses you took, when, and at what strength. The app's doctor report feature lets you bring a summary of your journey to prescriber appointments, so those conversations are based on real data rather than memory. You can also track side effects alongside your doses to spot any patterns worth discussing. For a broader guide to getting the most from your treatment, visit the Mounjaro journey hub.
Always follow the guidance of your prescriber or doctor — any decision about your dose, including what to do after a missed injection, should be made with them, never on your own.

Frequently asked questions.
Mounjaro is available in strengths from 2.5 mg to 15 mg. Treatment typically starts at the lowest dose and is increased gradually by your prescriber based on how you are tolerating the medicine and your individual progress. No single dose applies to everyone.
Your prescriber determines your dose based on your health, your response to the medicine, and how well you are tolerating it. Dose increases follow a step-up schedule designed to reduce side effects. This decision is always your prescriber's, not one to make independently.
If you miss a dose, do not double up or adjust your schedule without guidance. Check the patient information leaflet that came with your pen and contact your prescriber or doctor for advice. You can log the missed dose in GLP Trackr to keep an accurate record for your next appointment.
The available dose strengths are the same across both uses, but your prescriber decides the appropriate dose and schedule for your specific situation. If you are unsure why you have been prescribed a particular dose, speak directly with your prescriber or doctor.
GLP Trackr lets you log each injection with its date, time, and dose strength. Dose reminders help you stay on your weekly schedule, and your dose history builds into a record you can share with your prescriber at appointments.
