A Mounjaro tracker is a record of when you injected, where, and what happened afterwards. Veya keeps those three things together so a pattern is visible rather than remembered. It records what you enter and nothing else. It does not tell you what to take, and it is not a substitute for the advice of the prescriber who looks after your treatment.
Why Mounjaro users track
The reason people start tracking is almost never curiosity. It is an appointment coming up, or a symptom that may or may not be connected to the injection three days ago, and no reliable way to tell.
A weekly injection is easy to lose track of
Mounjaro is injected once a week. A daily medicine attaches itself to a routine and a missed one is obvious by lunchtime. A weekly one has no such anchor, and after a few weeks the question of whether you injected on Tuesday or Wednesday stops having an answer you can trust.
A logged date is the difference between knowing and reconstructing. It also gives every symptom you record afterwards something to be measured from.
Symptoms are only useful with a timeline attached
A prescriber can do a great deal with a date and very little with an adjective. Nausea that arrives the evening of an injection and clears by Friday is a different observation from nausea that has been constant for three weeks, and the two are indistinguishable by the time you are in the room describing them.
Recording the day something started, how long it lasted, and whether it followed a change is what turns a vague account into something a clinician can work with.
Injection sites need rotating, and rotation needs a record
The label directs that Mounjaro is injected under the skin of the abdomen or thigh, or into the back of the upper arm by another person, and that injection sites are rotated with each dose. Rotation only works if you can remember where the last one went.
A site log is a small thing that answers a question you would otherwise guess at every week.
Your prescription changes, and the record has to survive it
Treatment is reviewed and adjusted. When something changes, the useful question is what was different before and after, and that comparison only exists if you were recording through the change rather than starting afterwards.
A history that runs continuously across an adjustment is worth more than a detailed one that starts the week you noticed a problem.
How Veya tracks your Mounjaro
- Injection logThe date of each injection, with the site you used. The weekly cadence is visible as a pattern rather than held in your head.
- Symptom and side-effect notesWhat you noticed, the day it started, and how long it went on. Entries sit on the same timeline as your injections, so the gap between the two is something you can see.
- Weight and measurement entriesRecorded when you choose to record them, at whatever interval you and your prescriber find useful. Veya stores the numbers you enter and draws them over time.
- Appointment preparationYour recent entries, gathered into something you can read out or hand over, so the appointment starts from a record rather than from trying to recall six weeks at once.
- Reminders you setA prompt on the schedule you choose, for the things you have decided to record. Veya reminds you to make an entry; it has nothing to say about what your treatment should be.
- CSV exportYour entries out of the app as a CSV file, in normal use and after cancelling. It is your record, and it should be readable somewhere that is not Veya.
What to record across a change in your prescription
Treatment is reviewed and adjusted over time. Veya will not tell you what to take, and this page carries no schedule of amounts: that is between you and your prescriber, and it is on the patient information supplied with your medicine. What a tracker can do is make the period around a change legible afterwards. These are the entries worth having.
- The date something changed, recorded on the day rather than reconstructed later.
- Which day of the week you inject, and whether it stayed the same through the change.
- Any symptom that appeared, disappeared or changed character in the two weeks either side.
- How long each symptom lasted, which is usually more informative than how bad it felt.
- What you had eaten and drunk on a day a digestive symptom was notably worse.
- The injection site used each week, so a site-specific reaction can be told apart from a general one.
- Anything else that changed at the same time: a new medicine, an illness, travel, a different sleep pattern.
- The questions you want to ask at the next appointment, written down when they occur to you.

Read from the EMA summary of product characteristics for Mounjaro, sections 1, 2, 4.2 and 5.1, on 11 September 2026. Product information is reissued when a variation is approved. Always follow the patient information leaflet supplied with your own medicine, and speak to your prescriber or pharmacist about anything concerning your treatment.
Does Veya tell me what dose to take?
No, and it will not. Veya records what you enter. Decisions about your treatment belong to you and the prescriber who looks after it, and the patient information supplied with your medicine is the place to look for how it should be taken.
Can I track Mounjaro and another medicine in the same place?
Yes. Entries carry the medicine they relate to, so a history that spans a change of medicine stays in one record rather than splitting across two.
What happens to my entries if I stop paying?
CSV export works in normal use and after cancelling. Your record is exportable as a file you keep, rather than something that becomes unreadable when a subscription ends.
Does Veya work if I inject on a different day some weeks?
Yes. You record the date you actually injected. Nothing assumes a fixed day, and a week that moved is simply a week that moved.
Is Veya connected to Eli Lilly?
No. Veya is provider-neutral and independent. It does not sell, supply or prescribe medication, and it is not affiliated with any manufacturer. Mounjaro is named here to identify the medicine this page is about.
Do I have to log something every day?
No. A weekly injection and a note when something is worth noting is a complete record for most people. A tracker that demands daily attention is one you stop using by the third week.
Can I get my history out to show someone?
Yes. Entries export as a CSV file, which opens in a spreadsheet and prints. Several people find it easier to hand over a printed sheet than to pass a phone across a desk.
