The generic insulin lispro prefilled injection pens available in the U.S. are the "Lispro follow-on product" U-100 prefilled pen and the "Lispro-aabc" (insulin lispro-aabc) prefilled pens in both U-100 and U-200 concentrations.
Available Generic Formulations
Based on the most recent American Diabetes Association guidelines 1, 2, 3, the generic insulin lispro prefilled pens include:
Lispro Follow-On Product
- U-100 prefilled pen - This is the most affordable generic option with a median cost of $151 per 1,000 units (AWP) or $121 (NADAC) 1
Lispro-aabc (Insulin Lispro-aabc)
The FDA-approved insulin lispro-aabc is marketed under the brand name LYUMJEV and comes in multiple prefilled pen options 4:
- LYUMJEV KwikPen (U-100): Standard prefilled pen delivering 100 units/mL
- LYUMJEV Junior KwikPen (U-100): Delivers 0.5 to 30 units in 0.5-unit increments, designed for patients requiring finer dose adjustments 5
- LYUMJEV Tempo Pen (U-100): Another U-100 prefilled pen option

Cost Considerations
The generic "Lispro follow-on product" U-100 prefilled pen offers significant cost savings compared to branded options, with pricing approximately 40-50% lower than branded insulin lispro pens 2, 3. The median NADAC cost is $121 per 1,000 units compared to $102 for branded lispro U-100 prefilled pens (when generic pricing is used) 2.
Clinical Equivalence
These generic formulations demonstrate similar pharmacokinetics and pharmacodynamics to branded insulin lispro 6. The lispro-aabc formulation has been shown to be safe and effective when used in insulin pumps and standard injection devices, with no clinically significant differences in infusion set occlusions or hypoglycemia rates compared to branded products 6.
Device Features
All prefilled insulin lispro pens share common advantages 7, 8:
- Combine vial and syringe into a single device
- Allow push-button injections
- Vary in dosing increments (0.5 to 2-unit increments depending on the pen)
- Recommended for use with BD (Becton, Dickinson and Company) insulin pen needles 4
The Junior KwikPen specifically addresses the needs of patients requiring half-unit dosing, which is particularly valuable for children, adolescents, insulin-sensitive adults, and pregnant women 5.
