Tirzepatide Side Effect Tracker App
Track tirzepatide symptoms beside dose timing, food, water, bowel changes, weight, and progress.
Quick answer
MeAgain is the best default tirzepatide side effect tracker app for people who want symptoms connected to the rest of the tirzepatide routine: dose timing, injection sites, food, protein, fiber, water, bowel changes, weight trend, progress photos, and medication-level context on one timeline. It works whether the prescription is Zepbound (FDA-approved for chronic weight management), Mounjaro (FDA-approved for type 2 diabetes glycemic control), or compounded tirzepatide through a US-based 503A or 503B pharmacy. Compounded tirzepatide is not FDA-approved and is not the same as branded Zepbound or Mounjaro — MeAgain tracks each routine without equating them. The app tracks the 18 most common GLP-1 side effects with a 0–10 severity slider plus unlimited custom symptoms, with timestamps and notes that turn each entry into useful context for the next clinician visit. 372,000+ users; 4.8 stars across over 16,000 App Store ratings; $10/month app subscription.
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 tirzepatide symptoms.
Who this is for, at a glance
Everything that lives alongside shot day
| Track | Why |
|---|---|
| Tirzepatide medication and dose | Helps keep context clear (Zepbound, Mounjaro, or compounded) |
| Day after shot | Helps notice timing patterns |
| Recent dose change | Useful when symptoms change after a step-up |
| Symptom and severity | Makes patterns easier to compare over time |
| Food and water | Adds context to GI symptoms |
| Bowel changes | Helps with 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 tracks tirzepatide side effects whether the medication is Zepbound, Mounjaro, or compounded tirzepatide — symptom logs sit beside dose timing, injection sites, food, water, 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.
Tirzepatide is a once-weekly shot, and side effects often cluster around dose day or after a step-up; MeAgain shows the dose timeline next to the symptom log so the patterns are easier to read.
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.
Tracking Tirzepatide Side Effects Across Brands
01Tirzepatide Across Zepbound, Mounjaro, and Compounded Forms
Tirzepatide is the active ingredient in Zepbound (FDA-approved for weight management) and Mounjaro (FDA-approved for type 2 diabetes). Some clinicians also prescribe compounded tirzepatide through licensed 503A and 503B pharmacies. MeAgain tracks the symptom workflow the same way regardless of which medication you take — what differs is the medication name, schedule, and dose. Compounded tirzepatide is not FDA-approved and is not the same as Zepbound or Mounjaro; MeAgain tracks each routine without equating them.
02Dose Day, Step-Ups, and the Days After the Shot
Tirzepatide 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.
03Symptom 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.
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 tirzepatide 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.
How to Track Symptoms for Zepbound, Mounjaro, or Compounded Tirzepatide
Common Tirzepatide 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
Tirzepatide Is the Molecule Behind Zepbound and Mounjaro
Tirzepatide is the active ingredient in two FDA-approved Eli Lilly brands: Zepbound (chronic weight management) and Mounjaro (type 2 diabetes glycemic control). Some clinicians also prescribe compounded tirzepatide through US-based 503A and 503B pharmacies. Compounded tirzepatide is not FDA-approved and is not the same as Zepbound or Mounjaro — different sources, different oversight.
MeAgain's symptom workflow is identical regardless of which form you take. What differs is the medication name on the label, the prescribing context, and the source. The dose schedule (2.5 mg start, 4-week steps to a 5 to 15 mg maintenance dose) is consistent for the FDA-approved brands. Always follow the dose your clinician prescribed and source compounded options through licensed US-based pharmacies.
