  • 3 mL Pen (prefilled, 1,500 units of insulin), and

The prescribed TDI of U-500R will determine how many Pens or vials will be needed per month.

Do not freeze U-500R. Do not use U-500R if it has been frozen.1

Protect U-500R from heat and light.

Do not store the Pen with the needle attached to prevent

  • leaking

a An insulin product is considered in-use (open) once the stopper or septum has been punctured with a needle.

b Do not store the in-use U-500R Pen in the refrigerator.

c The storage and stability guidelines for insulin Pens differ from those for vials.  This is based on differences in the expected usage patterns for these insulin products.  The stability (in-use dating period) guideline established for Pens took into account the increased convenience of a Pen.  This increased convenience may lead to patients exposing his or her insulin to thermal (heat) and agitation conditions that would be greater than the exposure for insulin in vials.

Product Quality Assessment

If an insulin product is exposed to temperatures outside the recommend storage and handling range, Lilly personnel can perform a product quality assessment to determine potential impact to the quality of product.  This product quality assessment is not intended to replace the recommended storage or handling conditions for the insulin product.

Lilly can assess the potential impact of any temperature exposure to the product only after the event has occurred and only on a case-by-case basis.

  • You must be able to provide amount of time and what temperatures the insulin was exposed to outside the recommended storage and handling conditions.

  • The product quality assessment must occur after the temperature exposure has ended and the products have been stored as per recommended storage conditions. 

  • Please contact us at 1-800-LillyRx (1-800-545-5979) when a product quality assessment is needed.
