Humulin N Insulin Information
Humulin® N (NPH insulin) is a nonprescription diabetes medication. As an intermediate-acting product, it starts working more slowly and lasts longer than regular insulin. This medication is produced by combining a manufactured insulin with certain chemicals to make it last longer. NPH stands for Neutral Protamine Hagedorn, so named because it has a neutral pH, contains protamine, and was invented by a scientist named Hans Christian Hagedorn.
Humulin N is available in the following forms:
- Humulin N vials -- 10 mL, with 100 units of insulin per mL
- Humulin N pens -- 3 mL, with 100 units of insulin per mL.
