How Mounjaro Dosing Typically Works
Mounjaro is a once-weekly injectable medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. According to the electronic Medicines Compendium (eMC), the standard starting dose is 2.5 mg once weekly for the first four weeks. After that initial period, the dose is usually increased to 5 mg — and further adjustments are made by the prescriber over time, based on how well the medicine is tolerated and the individual's response.
Why the gradual approach matters
Starting at a lower dose gives the body time to adjust, which commonly helps reduce gastrointestinal side effects such as nausea. Moving to 5 mg — and potentially higher strengths such as 7.5 mg, 10 mg, 12.5 mg, or 15 mg — happens only when a prescriber considers it appropriate. These adjustments are not something to decide independently.
Can a prescriber ever start someone at 5 mg?
In practice, the starting dose is determined by your prescriber, who takes into account your full medical history, any other medicines you are taking, and other individual factors. If your prescriber has specifically directed you to begin at 5 mg, follow their guidance. If you are unsure about what dose you have been prescribed or why, the right step is to ask your prescriber or doctor directly — not to adjust the dose on your own.

If you are also curious about how starting doses work for a related medicine, the page on starting Wegovy at 1.7 mg covers similar ground. You may also find the page on beginning Mounjaro on 5 mg useful for further context.

Tracking Your Mounjaro Doses with GLP Trackr
Whatever dose your prescriber has started you on, keeping an accurate record of every injection is one of the most practical things you can do. GLP Trackr's dose logging feature lets you record each shot — the date, time, and dose strength — so your treatment history is always clear and in one place.
This is particularly useful at the start of treatment, when the schedule and dose strengths can feel unfamiliar. The app's dose reminders mean a weekly injection is much less likely to be forgotten, and if you ever do miss a dose, the log gives you an accurate record to discuss with your prescriber rather than relying on memory.
As your journey progresses, having a complete dose history alongside your weight and wellbeing data can make appointments with your prescriber more productive — they can see exactly what you have taken and when, in the context of how you have been feeling.
For context on how starting doses work across GLP-1 medicines, the page on at what dose Wegovy starts working offers a useful comparison point.
Important: any decision about your starting dose or any dose change belongs with your prescriber. GLP Trackr helps you record and track your journey — it is not a substitute for your prescriber's guidance, and it does not provide medical or dosing advice. If you have questions about your prescribed dose, contact your healthcare professional.

Frequently asked questions.
The standard starting dose for Mounjaro is 2.5 mg once weekly for the first four weeks, with 5 mg typically coming next. Whether a different starting dose is appropriate for you is a decision for your prescriber, based on your individual circumstances.
Mounjaro is available in several strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. The dose a person is on at any point is determined and adjusted by their prescriber over time.
Dose increases are always decided by your prescriber or doctor — never independently. They take into account your tolerance, response, and medical history before recommending any change.
If you are uncertain about what dose you have been prescribed or why, contact your prescriber or doctor directly. Do not adjust your dose without their guidance. GLP Trackr can help you log your doses to support that conversation.
GLP Trackr lets you log each injection with its date, time, and dose strength, and sends reminders so you do not miss a weekly dose. It is a tracking tool — all dosing decisions remain with your prescriber.
