Soultion for Cartrige & Novopen Fitting - pls read

Dear All;

Subject:
“Novonordisk Cartriges dont fit in normal pens”

after my nightmare weekend ; being left without pen for my novonordisk insulin " Levemir " my endo gave me the below solution :

A sales representative of Novonordisk explained that their insulin cartriges do not fit in normal pens as they have covered the head of the cartrige with a metal cover so it will fit only in their Novonordisk pens. ( Very smart )

The sales representative of Novonordisk advised my endo to just carefully cut of the green metal on the cartridge of Levemir ( u can use a scissor to remove the metal ring ) and than it will fit in all other pens…
