-give at meal-times, as separate injections, skip dose if < 30 g carbs
rapid acting insulin facts
-aspart, lispro, glulisine
-controls mealtime BG, onset ~ 15 mins, peaks 1-2 hrs and lasts 3-5 hrs
regular insulin facts
used for mealtime BG control, onset is 30 mins, peaks ~2 hrs ad lasts 6-10 hrs
Basal insulin: Detemir facts
long acting, providing baseline coverage
-onset 3-4 hrs, lasts ~1 day with no peak
Intermediate acting insulin facts
-NPH
-onset 1-2 hrs, peaks 4-12 hrs and lasts 14-24 hrs
Basal Insulin: Glargine facts
-long acting, onset 3-4 hrs (Tuojeo lasts 6 hrs), lasts ~1 day with no peak
Basal insulin: Deglutide facts
starts faster and lasts longer, onset ~ 1 hr and lasts 42+ hours with no peak
All insulin SE/warnings
CI: Afrezza inhaled insulin- any lung diease, including asthma and COPD, do not use Afrezza in smokers
Warnings: hypoglycemia, hypokalemia: insulin facilitates K+ entry into cells
SE: weight gain, lipatrophy, lipphypertrophy
Notes:
-do not shake: turn suspensions (NPH, Protamine mixes) up/down slowly or roll between hands
-store unopened insulin vials and pens in the refrigerator
DDI:
-Rosiglitazone: inc risk of HF, do not use with insulin

Insulin dosing in DM1
1) calculate TDD (0.5 units/kg/day, using TBW)
2) divide the TDD into 50% basal and 50% bolus
3) divide the bolus insulin evenly among 3 meals
Insulin Conversions
most conversions are 1:1
EXCEPTIONS:
1) BID NPH to qd insulin glargine (Lantus, Toujeo, Basaglar)
–> use 80% of total daily NPH dose as initial insulin glargine dose
2) once daily Toujeo to once daily Lantus or Basaglar:
–> use 80% of the total daily Toujeo dose as the inital Lantus or Basaglar dose
Selecting an Insulin Syringe
-0.3 mL up to 30 units
-0.5 mL for 30-50 units
-1 mL for 51-100 units
Meal time insulin dosing
A: ICR rule of 450 for REGULAR
450/ total daily dose of insulin (TDD)
B: ICR rule of 500 for RAPID- ACTING
500/total daily dose of insulin (TDD)
Calculating correction factor: regular insulin
-rule of 1500
1500/ total daily dose of insulin = correction factor for 1 unit of regular insulin
