Two medicines, side by side
Insulin glargine vs insulin lispro
Insulin glargine and insulin lispro are both labeled for type 2 diabetes and type 1 diabetes. Drugs@FDA records approvals of insulin glargine since 2015 and of insulin lispro since 2017. Pharmacies paid $2.90 per mL (Insulin glargine-yfgn u100 pen) and $10.19 per mL (Insulin lispro 100 unit/mL kwikpen) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Insulin glargine's other strengths are brand-only: $5.92 per mL (Rezvoglar 100 unit/mL kwikpen). How each works, in its label's words: Insulin glargine, “The primary activity of insulin, including insulin glargine, is regulation of glucose metabolism.”; Insulin lispro, “Regulation of glucose metabolism is the primary activity of insulins and insulin analogs, including insulin lispro products.”
