How to Track Mounjaro Injections (2026 Guide) + Free Tracker App
Step-by-step 2026 guide to tracking Mounjaro injections — dose, site and titration — plus a free tirzepatide tracker app on the App Store.

Weekly Mounjaro injections sound simple until life gets in the way. Travel, a changed routine, or a dose increase can make it surprisingly hard to remember exactly when you last injected — and which pen strength you used.
Why a simple injection log helps
Mounjaro (tirzepatide) is typically taken once per week, often with gradual dose increases over the first months. A reliable record helps you:
- Confirm your last injection date before taking the next dose
- Track which strength you used as you titrate
- Note injection site rotation if your clinician recommends it
- Prepare accurate information for appointments
This is personal tracking — not medical advice. Your prescriber sets your schedule and dose.
What to log each week
At minimum, most people record:
- Date and time of the injection
- Dose strength (pen strength or mg)
- Injection site if you rotate (abdomen, thigh, upper arm)
- Any immediate notes — mild soreness, for example
Logging takes seconds when you do it on injection day. Trying to reconstruct the past from memory is much harder.
Common mistakes to avoid
Waiting until appointment day. Scrambling to remember eight weeks of doses is stressful. A weekly habit prevents this.
Mixing up pen strengths. Tirzepatide titration means your pen strength changes. Record the actual dose injected, not just "I took Mounjaro."
Scattered tools. Calendar for dates, Notes for side effects, scale app for weight — piecing it together wastes time. One tracker keeps the full picture visible.
