I'm on 10mg husband is on 2.5. We cannot really afford 2 pens moving forward. Can I give him 4 doses from my pen but 15 clicks a time? What would the implication be of more dosage per ml of liquid carrier? Hope you understand what I mean. 2.5 is spread over 60mls and 10 is also spread over 60mls. Meaning if u have 2.5 from a 10mg pen you get less liquid. Thanks in advance.
