Yes, you can take your Mounjaro injection one day late
If you miss your Mounjaro dose, you can take it as soon as possible within 4 days (96 hours) after the missed dose, then resume your regular weekly schedule. 1
Specific Instructions for Missed Doses
Within 4 Days Late (≤96 hours)
- Take the missed dose immediately when you remember
- Resume your regular once-weekly dosing schedule on your originally scheduled day
- No dose adjustment needed
- The timing between doses should be at least 3 days (72 hours) 1
More Than 4 Days Late (>96 hours)
- Skip the missed dose entirely
- Take your next dose on the regularly scheduled day
- Do not take two doses within 3 days of each other 1
Changing Your Weekly Schedule
If you need to permanently change your injection day:
- You can modify the day of the week you inject Mounjaro
- Ensure at least 72 hours (3 days) pass between any two doses 1
- This flexibility allows you to adjust your schedule as needed
Important Safety Considerations
Never double up on doses. Taking two injections within 3 days can increase your risk of:
- Severe gastrointestinal side effects (nausea, vomiting, diarrhea)
- Potential hypoglycemia if you're also taking other diabetes medications 1
The 4-day window provides reasonable flexibility for real-world adherence while maintaining therapeutic drug levels, as Mounjaro is designed for once-weekly administration with sustained action throughout the week.
