Teach patient/family:

• 
That regular assessments are required, diabetics to monitor blood glucose

• 
About SUBCUT inj if patient or other persons will be giving inj

 
That product may cause dizziness, drowsiness, weakness; to avoid hazardous activities if these occur; to report abdominal pain immediately
