What needles are compatible with the KwikPen?

The Mounjaro KwikPen is compatible with ISO 11608-2 compliant pen needles from brands such as BD, Novo Nordisk, and Terumo, in any length and gauge combination: 

  • Lengths: 4 mm, 5 mm, 6 mm, 8 mm, 12.7 mm
  • Gauges: 29G, 31G, 32G, 33G, 34G.1

Not all length and gauge combinations are commercially available. Patients should consult their healthcare provider for pen needle recommendations and guidance on proper injection technique.1,2

ISO compliant and compatibility information may be found on pen needle packaging, manufacturer’s website, or by contacting the manufacturer directly.1

The length of the needle does not affect how much solution is injected.1

The needle gauge refers to how large an opening the needle has (ie, needle diameter). With most needles, the smaller the opening, the more force a patient may need to use to deliver a dose.1

The accuracy of the dose is the same for all needles if the patient follows directions in the user manual.1

What needle length should be used?

Mounjaro supplied in KwikPen should be administered via SC injection.1 Pen needles available for SC injection typically range from a length of 4 mm to 12.7 mm (5/32 inch to 1/2 inch).3

According to a review of the literature, pending availability of needle length, shorter needles are more appropriate and generally better tolerated. Pen needles of 4 mm are suitable for adult patients.4,5

The decision on needle gauge and length remains at the discretion of the physician or pharmacist.2

Why are there no needles in the pack?

Eli Lilly and Company does not manufacture any needles.

Furthermore, the Mounjaro KwikPen is compatible with different kind of needles, including needles of different sizes, and needles of different manufacturers with different characteristics. Supplying medicine and needles separately allows the health care professional and patient to choose a needle that is appropriate for the patient.
