How MeAgain Tracks Your Mounjaro Week
Shot Log, Reminders, and Late Shots
MeAgain logs each Mounjaro shot with its dose, time, and site, reminds you on shot day, and shows the days left until the next one. You take Mounjaro once a week, any time of day, with or without food. When a shot is missed, the next-dose card shows it as overdue for the 4 days the label allows for a late dose, then switches back to counting down to your usual day.
Each Dose Step, Kept in Your Log
MeAgain saves the dose with each shot and dates every other entry, so you can scroll back to see how the weeks on 5 mg went before the move to 7.5 mg. Mounjaro starts at 2.5 mg. If your blood sugar needs more help, the label allows a raise of 2.5 mg after at least 4 weeks on each dose, up to 15 mg for adults. With Premium, progress photos and Journey Cards keep the changes you see in the mirror. If you switch medications, your past logs keep the medication they were logged with.
Injection Site Rotation
MeAgain records where every Mounjaro shot went on a body map. Switch on alternating sides and the app proposes the other side for the next shot, so the pattern holds even in a busy week. The label lists the abdomen and thigh for your own shots, and the back of the upper arm when another person gives it, with a new site each dose.
Side Effects, Including the Ones Not on a List
MeAgain has 29 built-in symptoms, and you can add your own, like brain fog. Rate each from 0 to 10, and the dated entries make it easy to look back at the days after each raise. Nausea, diarrhea, and lower appetite lead the label's list of common side effects, and they tend to show up after a shot or a step up.
Food, Protein, and Water on Low-Appetite Days
MeAgain logs meals by photo, barcode, voice, search, or quick entry and tracks protein, fiber, and water against daily goals. Lower appetite is among the side effects the Mounjaro label lists most often, which can make protein and water hard to reach. The Capybara home screen widget keeps the day's progress on your home screen, so a short day of eating does not go unnoticed.
Your Estimated Tirzepatide Level
The MeAgain medication graph estimates how your tirzepatide level rises and falls, from the shots you log. Tirzepatide, the medicine in Mounjaro, has a half-life of about 5 days, so its level rises after a shot and eases down before the next, which helps explain why appetite or nausea changes through the week. The graph is an estimate, not a measurement, and it never tells you what dose to take.
Mounjaro Basics: What to Know While You Track
Mounjaro is tirzepatide, a weekly shot from Eli Lilly. The FDA label approves Mounjaro together with diet and exercise to improve blood sugar in adults and children 10 and older with type 2 diabetes and to lower the risk of heart attack, stroke, and heart-related death in adults with type 2 diabetes at high risk for them. Zepbound, also tirzepatide from Eli Lilly, is the brand whose label covers lowering body weight; see the Zepbound tracker for that schedule.
The most common side effects on the label are nausea, diarrhea, lower appetite, vomiting, constipation, indigestion, and stomach pain. In SURPASS-1, a 40-week trial on the label, 478 adults with type 2 diabetes took Mounjaro alone or a placebo, and their A1C, a three-month average of blood sugar, fell more on each Mounjaro dose than on placebo.
Mounjaro dose schedule
From the current FDA label. Mounjaro is taken once a week.
| When | Weekly dose | Step |
|---|---|---|
| First 4+ weeks | 2.5 mg | Starting dose |
| After 4+ weeks at 2.5 mg | 5 mg | Raise if needed |
| After 4+ weeks at 5 mg | 7.5 mg | Raise if needed |
| After 4+ weeks at 7.5 mg | 10 mg | Raise if needed |
| After 4+ weeks at 10 mg | 12.5 mg | Raise if needed |
| After 4+ weeks at 12.5 mg | 15 mg | Highest dose |
Your prescriber decides if and when to raise the dose. For children 10 and older, the label's highest dose is 10 mg. A missed shot can be taken within 4 days; past that, the label says to skip it and keep your regular day. This table summarizes the FDA label for education only. It is not medical advice.
