Study Notes
Rapid-Acting Insulin
- Onset: 10-15 minutes
- Peak: 1-2 hours
- Duration: 3-5 hours
- Administration: Subcutaneous (KwikPen or Flex Pen)
- Insulin lispro (Humalog) and aspart (NovoRapid) are examples
- Administered at mealtimes
- Interrupt the patient's meal for administration
- Patient must eat after injection to prevent hypoglycemia
Short-Acting Insulin
- Onset: 30 minutes
- Peak: 2-3 hours
- Duration: 6 hours
- Administration: Intravenous (bolus/infusion) for diabetic ketoacidosis and diabetic coma, subcutaneous and intramuscular (rare)
- Administered at mealtimes
- Regular insulin (Humulin R) is an example
Intermediate-Acting Insulin
- Onset: 1-3 hours
- Peak: 4-10 hours
- Duration: 12-18 hours
- Administration: Subcutaneous, typically once daily
- Insulin isophane suspension (NPH) is an example
- Cloudy appearance
- Often combined with regular insulin to reduce the number of injections per day
Long-Acting Insulin
- Onset: 90 minutes
- Peak: No peak effect; constant level of insulin in the body
- Duration: 24 hours
- Administration: Subcutaneous, once daily (morning/evening)
- Insulin glargine (Lantus, Basaglar) is an example
- Refers to it as basal insulin
Rapid-acting Insulin
- Onset: 10-15 minutes
- Peak: 1-2 hours
- Duration: 3-5 hours
- Administration: Subcutaneous (KwikPen or Flex Pen) at mealtimes; interrupt the patient's meal; the patient must eat after injection to prevent hypoglycemia
- Examples: Lispro (Humalog), Aspart (NovoRapid)
Short-acting Insulin
- Onset: 30 minutes
- Peak: 2-3 hours
- Duration: 6 hours
- Administration: Intravenous (bolus/infusion) for diabetic ketoacidosis (DKA) or diabetic coma; subcutaneous; intramuscular (rare)
- Example: Regular insulin (Humulin R)
Intermediate-acting Insulin
- Onset: 1-3 hours
- Peak: 4-10 hours
- Duration: 12-18 hours
- Administration: Subcutaneous, once daily
- Example: Insulin isophane suspension aka NPH (Humulin N)
- Cloudy appearance
- Often combined with regular insulin to reduce the number of injections per day
Long-acting Insulin
- Onset: 90 minutes
- Peak: No peak effect; provides a constant level of insulin in the body
- Duration: 24 hours
- Administration: Subcutaneous, once daily (am/pm) - usually at bedtime
- Example: Insulin glargine (Lantus, Basaglar)
Rapid-Acting Insulin
- Onset: 10-15 minutes

- Administered at mealtimes
- Example: Regular insulin (Humulin R)

- Onset: 1-3 hours
- Peak: 4-10 hours
- Duration: 12-18 hours

- Often combined with regular insulin to reduce the number of injections daily
Long-Acting Insulin
- Onset: 90 minutes
- Peak: No peak effect - constant level of insulin in the body (basal insulin)
