Humulin 70/30 is an insulin that combines the short action of regular human insulin (Humulin R U-100) and the intermediate action of Humulin N. Humulin 70/30 is available in the prefilled Humulin® 70/30 KwikPen® or in a Humulin 70/30 U-100 vial.
Humulin 70/30 is injected under the skin. It should not be injected into a vein or muscle. Doses of insulin are measured in units. U-100 insulins, including Humulin 70/30, contain 100 units/mL. With the Humulin 70/30 vial, it is important to use a syringe that is marked for U-100 insulins.
