  Step 2 Calculate Units per Day
   units per day = (priming units + prescribed units) x doses per day
  Priming Units:
  Prescribed Units:
  Doses per Day:
  Calculate

  Step 3 Calculate Days Per Pen

  Units Per Day:
  Units Per Pen:
  Calculate

Step 4 Calculate Pens to Dispense
pens to dispense = number of days as Prescribed / days per pen
Number of days as Prescribed:
Days Per Pen:
Calculate
 

Step 5 Calculate Days Supply
 days supply = numbers of pens to dispense * units per pen / units per day
