The UnoPenTM device

NGENLA is administered by the pre-filled, multi-dose, disposable UnoPen – giving patients and caregivers the confidence to administer treatment and get back to moments that matter.

  • Low injection volume for paediatric patients (<0.6mL) and small needle gauge [31G-32G].
  • No reconstitution required.
  • Multidose, disposable and prefilled.
​​​​​​​The 24mg Pen is suggested for doses up to 12mg. The 60mg pen is suggested for doses 12mg and over.


​​​​​​​Administration​​​​​​​1

NGENLA is to be injected in the abdomen, thighs, buttocks or upper arms. The site of injection should be rotated at each administration. Injections to the upper arms and buttocks should be given by the caregiver.

• Administer NGENLA once weekly, on the same day each week, at any time of the day.

• The day of weekly administration can be changed if necessary as long as the time between 2 doses is at least 3 days (>72 hours). 

• If a dose is missed, NGENLA should be administered as soon as possible within 3 days of the missed dose; then the usual once-weekly dosing schedule should be resumed. After 3 days of missed dose, the dose should be skipped and the next dose administered on the regular scheduled day.
