Look for the Aqua and White Packaging on Humulin R U-500 KwikPen
Humulin R U-500 insulin will now come in a KwikPen device.
For years, this concentrated form of regular insulin has come in a 20 mL vial...with 500 units/mL instead of the usual 100 units/mL.
But there's often confusion about drawing up U-500 with a U-100 syringe. If it's not done right, it can lead to a FIVE-fold overdose.
