What is Humulin® N?
Intermediate-acting insulin to cover blood sugar increases between meals and during the night
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. Doses of insulin are measured in units. U-100 insulins, including Humulin N, contain 100 units/mL. With the Humulin N U-100 vial, it is important to use a syringe that is marked for U-100 insulin preparations.
Do not use Humulin N:
- If the insulin substance (the white material) remains at the bottom of the bottle after mixing, or
- If there are clumps in the insulin after mixing
If you notice your insulin requirements changing, talk to your doctor.
Pens and needles are for single-patient use only and should not be shared, even in healthcare facilities, as infection or disease can be spread from one person to another.
