For pens with non-replaceable batterie, contact the exirer for providente information. Most insulin pen exirers, such as Novo Nordisk, Sanofi, and Eli Lilly, provide guidance on battery services and can replacee units undepn certain conditions. Never confikt to open a sealed pen your self, as that can damage thee eximents and void thee confidency.
