Trulicity-to-Mounjaro switch record
A record for the weeks around the switch: your last Trulicity dose, your first Mounjaro dose and device, and a log of glucose, side effects and any change to other diabetes medicines. The label rules that differ between the two medicines, such as missed doses and room-temperature storage, are side by side.

- Which Mounjaro device will I get, and who will show me how to use it?
- What HbA1c or weight change would make us review the plan?
- Does my plan need a prior authorization before the first fill?
