How Mounjaro Dosing Generally Works
Mounjaro comes in several dose strengths — 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg — delivered as a once-weekly injection. According to the electronic Medicines Compendium (eMC), treatment is typically initiated at the lowest strength and increased incrementally, at intervals determined by your prescriber, to help your body adjust and to manage any side effects.
The pace and extent of any dose increase is an individual decision made between you and your prescriber, based on your response, tolerability, and clinical history. There is no universal "right" dose — what works well for one person may not be appropriate for another.
What stays constant
- Mounjaro is taken once a week, on the same day each week where possible.
- Dose changes are always prescriber-led — never something to adjust on your own.
- The medicine is a dual GIP and GLP-1 receptor agonist, meaning it acts on two appetite-regulating pathways to support a feeling of fullness and reduce appetite, though individual responses vary.
If you are curious about how a specific strength fits into the broader titration picture, the page on Mounjaro dose stages and titration covers this in more detail. You may also find it helpful to read about starting your first dose of Mounjaro if you are early in your journey.
For information on a widely discussed mid-titration point, see the guide to Mounjaro 5 mg.

Tracking Your Mounjaro Doses with GLP Trackr
Keeping an accurate record of every dose you take is one of the most practical things you can do throughout your Mounjaro journey — and GLP Trackr's dose logging feature makes this straightforward. Every time you inject, you can log the date, time, and dose strength so you always have a clear, timestamped record of where you are in your treatment schedule.
This matters more than it might seem. If you ever need to discuss your progress or tolerability with your prescriber, having a complete dose history in one place means the conversation is grounded in real data rather than memory. The app's dose reminders also help ensure you stay on your once-weekly schedule without losing track.
Beyond dose logging, GLP Trackr lets you record side effects and how you feel after each dose — useful context to bring to any prescriber appointment, especially during the early weeks when your body is adjusting to a new strength.
Any decision about your dose — including when or whether to increase — belongs with your prescriber. GLP Trackr helps you observe and record your experience; it is not a substitute for clinical guidance. If you have questions about your specific dose or titration plan, speak with your prescriber or doctor directly. You can explore more about managing your treatment in the broader guide to finding the right Mounjaro dose for weight loss.

Frequently asked questions.
Mounjaro is started at 2.5 mg once weekly and increased gradually under prescriber supervision. Available strengths go up to 15 mg. The appropriate dose for any individual is determined by their prescriber based on response and tolerability — it is not a self-directed decision.
Your prescriber determines your dose based on how your body responds, any side effects you experience, and your clinical history. Dose increases follow a structured titration schedule and are never something to adjust without speaking to your prescriber or doctor first.
What to do after a missed dose is a decision for your prescriber — do not double up or adjust your schedule without their guidance. You can log a missed dose in GLP Trackr to keep your record accurate and discuss it at your next appointment. Refer to your official patient information leaflet for further guidance.
GLP Trackr lets you log the date, time, and strength of each injection, set weekly dose reminders, and record how you feel after each dose. This creates a clear history you can review with your prescriber, making appointments more informed and productive.
