Mounjaro Side Effect Tracker App
Track Mounjaro symptoms beside dose timing, injection sites, food, water, bowel changes, weight, and progress.
Quick answer
MeAgain is the best default Mounjaro side effect tracker app for people who want symptoms connected to the rest of the Mounjaro routine: dose timing, injection sites, food, protein, fiber, water, bowel changes, weight trend, progress photos, and medication-level context. It tracks the 18 most common GLP-1 side effects — nausea, constipation, diarrhea, vomiting, abdominal pain, dyspepsia, reflux, fatigue, headache, dizziness, injection-site reactions, and more — plus unlimited custom symptoms with a 0–10 severity slider, timestamps, and notes. Mounjaro is Eli Lilly's once-weekly tirzepatide shot for type 2 diabetes glycemic control (Zepbound contains the same active ingredient and is FDA-approved for chronic weight management instead); symptoms often cluster around dose day or after a step-up to the next dose level. 372,000+ people use MeAgain; 4.8 stars across over 16,000 App Store ratings; the core subscription is $10/month on iPhone and Android.
Bottom line: MeAgain is for tracking and education. It does not diagnose symptoms, decide whether a symptom is dangerous, or recommend dose changes. Talk with a licensed clinician about severe, persistent, unusual, or concerning Mounjaro symptoms.
Who this is for, at a glance
Everything that lives alongside shot day
| Track | Why |
|---|---|
| Mounjaro dose and timing | Keeps symptoms near dose day |
| Day after shot | Helps show timing patterns |
| Recent dose change | Helps explain new or changing symptoms |
| Symptom and severity | Makes changes easier to compare |
| Food and water | Adds context to GI symptoms |
| Bowel changes | Useful for constipation/diarrhea context |
| Weight and appetite | Shows broader progress context |
| Notes for your clinician | Makes the next visit easier to prepare |
What MeAgain does not do: No medical advice, no diagnosis, no treatment, no insurance billing. MeAgain is a tracking and education app, not a clinical service — clinical decisions stay with your licensed clinician.
Key takeaways
MeAgain is the Mounjaro side effect tracker app where every symptom log connects to dose day, injection sites, food, water, bowel changes, weight, and progress on one timeline.
Log nausea, constipation, diarrhea, vomiting, abdominal pain, fatigue, headache, and injection-site soreness — the 18 most common GLP-1 symptoms — plus unlimited custom symptoms with a 0–10 severity slider.
Mounjaro is a once-weekly tirzepatide shot for type 2 diabetes (Zepbound is the same molecule for weight management); side effects often cluster around dose day or after a step-up, and MeAgain shows the dose timeline next to the symptom log.
After a dose increase from 2.5 mg through 15 mg, the timeline lets you compare the new dose week to the previous one — useful for clinician check-ins where you want notes instead of memory.
372,000+ users track GLP-1 with MeAgain, and the app holds 4.8 stars across over 16,000 App Store ratings on iPhone and Android.
Why Mounjaro Symptoms Vary by Dose Week
01Dose Day, Step-Ups, and the Days After the Shot
Mounjaro starts at 2.5 mg, steps up every 4 weeks, and reaches a maintenance dose between 5 mg and 15 mg depending on your routine. Side effects often feel different by week — strongest in the days after a shot, easier later in the week, sometimes amplified by a step-up. MeAgain shows the medication graph and dose history next to your symptom log so you can see whether nausea hit the day after the shot, whether constipation followed a low-fiber stretch, or whether the most recent step-up changed the week.
02Symptom Log With Severity, Custom Symptoms, and Notes
MeAgain includes the 18 most common GLP-1 side effects — nausea, constipation, diarrhea, vomiting, abdominal pain, dyspepsia, reflux, fatigue, headache, dizziness, injection-site reactions, and more — plus unlimited custom symptoms when the preset list does not fit. The 0–10 severity slider, timestamps, and notes turn each entry into something useful later: not just a flag that something happened, but enough context to compare one rough day to another.
03Food, Water, and Bowel Changes Beside the Symptom Log
Mounjaro side effects often overlap with food and hydration. A larger meal may sit longer. A low-water stretch may show up as fatigue or headache. Constipation often follows low-fiber days. MeAgain keeps food, protein, fiber, water, and bowel-change logs on the same timeline as the symptom log — so a rough week is something you can read instead of trying to reconstruct.
04Built for Tracking, Not for Medical Decisions
MeAgain helps you remember what happened and bring clearer notes to a clinician conversation. It does not diagnose Mounjaro side effects, decide whether a symptom is dangerous, or recommend dose changes. Talk with a licensed clinician about severe, persistent, unusual, or concerning symptoms — including severe abdominal pain, persistent vomiting, signs of dehydration, trouble breathing or swallowing, or yellowing skin.
Tracking Mounjaro Side Effects for Type 2 Diabetes Care
Common Mounjaro Side Effects Worth Tracking
- Nausea, especially in the days after a shot or after a step-up
- Constipation, diarrhea, or a week that swings between both
- Vomiting on a rough week
- Abdominal pain or feeling too full too fast
- Fatigue or lower energy than usual
- Heartburn, reflux, or dyspepsia
- Headache or dizziness during a dose change
- Injection-site soreness or skin reactions
- Appetite changes that make protein or hydration easy to miss
Mounjaro Is the Type 2 Diabetes Brand of Tirzepatide
Mounjaro is Eli Lilly's tirzepatide injection FDA-approved for type 2 diabetes glycemic control, while Zepbound contains the same active ingredient and is FDA-approved for chronic weight management. The dose schedule on Mounjaro is the same step-up structure as Zepbound — 2.5 mg start, 4-week steps to a 5 to 15 mg maintenance dose — but the prescribing context and any related blood-sugar tracking sit alongside symptoms.
If you also track blood glucose, Mounjaro's symptom patterns can overlap with hypoglycemia signals like dizziness, fatigue, or sweating. MeAgain logs Mounjaro symptoms with timestamps so you can pair them with HealthKit-synced glucose readings and bring clearer notes to a diabetes care visit. Talk with a licensed clinician about glycemic targets and any blood-sugar concerns.

Mounjaro Side Effect Tracker — FAQs
Track the symptom, severity on a 0–10 scale, dose timing (which day after the shot), food before the symptom, water and fiber, bowel changes, weight, and any notes about how the day felt. MeAgain keeps each of those fields on one timeline so a rough week is something you can read instead of guess.
