Proper cannula length selection and placement is critical to ensure
intended dosing and administration of VYALEV. Select the cannula size
that is long enough to deliver the infusion into the subcutaneous tissue
but will not inltrate the muscle, which can cause pain and/or cause
the cannula to bend and potentially result in an occlusion. To make this
selection, consider different patient characteristics, including the patient’s
abdominal adipose tissue thickness, abdominal girth, and body mass
index. Patients should be trained on proper placement techniques and
management of the cannula and infusion set.
