Plunger Position: The plunger sits further down in the cartridge when the pen is unused.
Extended Plunger: A new internal component has been added behind the plunger, extending its length. This is shown in the Mounjaro KwikPen Guide to Parts section in Instructions For Use (IFU).
Remaining Medicine: After the fourth dose, the plunger will be near the end of the pen, clearly indicating the pen is ready to be discarded.
Why the change?
The Mounjaro® (tirzepatide) KwikPen® device has been modified to reduce leftover medicine and make it easier to track that the final dose has been administered indicating that the pen is ready to be discarded. The modified KwikPen® works the same way as the initial device.
The initial and modified Mounjaro® KwikPens® are both disposable multi-dose single-patient-use pre-filled pens, containing the volume of solution necessary for priming before each injection and the delivery of 4 fixed 0.6mL doses (one dose administered weekly).
