Tirzepatide Dosing Calendar: Track Your Weekly Schedule
Why tracking matters: Tirzepatide is injected once weekly. Missing doses disrupts the medication's steady-state blood level and can slow your progress. A simple tracking system prevents this.
Setting Up Your Weekly Injection Day
Choose one day of the week and commit to it. Best practices:
- Pick a day that is consistent in your schedule — not a day that frequently changes
- Set a recurring phone alarm or calendar event with the label "Injection Day"
- Many people choose Sunday (start of week, easy to remember) or Friday (side effects fall on weekend rest days)
- Tie it to an existing weekly habit — a gym session, a meal prep day, a standing appointment
Sample 20-Week Dosing Calendar
| Week | Dose | Injection Day | Notes |
|---|---|---|---|
| 1 | 2.5mg | Your chosen day | First injection — expect mild adjustment |
| 2 | 2.5mg | Same day | — |
| 3 | 2.5mg | Same day | — |
| 4 | 2.5mg | Same day | Last week at 2.5mg |
| 5 | 5mg | Same day | First escalation — may feel stronger effects |
| 6–8 | 5mg | Same day | Allow adjustment |
| 9 | 7.5mg | Same day | Second escalation |
| 10–12 | 7.5mg | Same day | — |
| 13 | 10mg | Same day | Third escalation |
| 14–16 | 10mg | Same day | — |
| 17 | 12.5mg | Same day | Fourth escalation |
| 18–20 | 12.5mg | Same day | — |
What to Log Each Week
Keep a simple weekly log — a notes app or spreadsheet works fine:
- Date of injection
- Dose injected (mg)
- Injection site used (rotate between abdomen, thigh, arm)
- Any side effects and severity (1–10)
- Weekly weight (optional but useful)
💡 Even a simple note on your phone the day of each injection is enough. The goal is to confirm you injected on the right day and track patterns in side effects across dose escalations.
Missed Injection — What to Do
If you miss your injection day:
- Less than 4 days late: Inject as soon as you remember, then resume your normal weekly schedule
- 4 or more days late: Skip the missed dose and inject on your next scheduled day — do not double up
