Question: is humulin n long acting?
Answer: Humulin N is an intermediate acting insulin that is slower to act and lasts longer than regular human insulin. Humulin N is available in the prefilled Humulin® N KwikPen® or in a Humulin N U-100 vial. Humulin N is injected under the skin. It should not be injected into muscle or veins.
