Insulin Stacking vs. Therapeutic Accumulation

• “Insulin stacking” is the excessive accumulation of insulin within the circulation

• Typically occurs with the administration of rapid‐acting insulin to correct hyperglycemia

• Described as:• “…the practice of providing correctional doses of insulin before a prior dose of prandial insulin (or the peak action of neutral protamine Hagedorn, [NPH]) has had its full effect.”1

• “…previously infused insulin still has an effect on future glucose values.”2

Insulin Stacking vs. Therapeutic Accumulation

• Therapeutic, or steady‐state accumulation is a normal part of the PK process

• Enables long‐acting insulin to reach a stable, steady‐state condition

• Important to dose the basal insulin in appropriate amounts and titrate at appropriate time intervals to allow for steady‐state accumulation and avoid “overshooting” the target fasting blood glucose
