Novo Nordisk: The Company Behind Novolin N
Novolin N is manufactured by Novo Nordisk, a renowned Danish pharmaceutical company that is one of the world's leading providers of diabetes care products. The company's origins trace back to the 1920s and are rooted in the early commercialization of insulin. Two Danish companies, Nordisk Insulaboratorium and Novo Terapeutisk Laboratorium, were pioneers in insulin production after the Canadian discovery in 1921. Following decades of competition, these two companies merged in 1989 to create the modern-day Novo Nordisk. This rich heritage in insulin development has positioned Novo Nordisk at the forefront of the diabetes treatment market for nearly a century.
The Heritage of Insulin Manufacturing
Following the discovery of insulin, the ability to mass-produce this life-saving hormone became crucial. Early forms of insulin were derived from animal sources, but advancements in biotechnology led to the development of synthetic "human" insulin, which is structurally identical to the insulin produced by the human pancreas. Novo Nordisk was a key player in this evolution, eventually using genetically engineered yeast cells to produce human insulin on a large scale. Novolin N is a product of this long history of innovation and manufacturing expertise.
What is Novolin N? An Intermediate-Acting Insulin
Novolin N is an intermediate-acting NPH (Neutral Protamine Hagedorn) human insulin. It is a sterile, white, and cloudy suspension that works by supplementing the body's natural insulin levels to help control high blood sugar in people with diabetes. As an intermediate-acting insulin, it has a slower onset of action compared to short-acting insulins, with effects lasting longer. This makes it particularly useful for controlling blood sugar between meals and overnight. In some markets, particularly in the U.S., it is also available under the ReliOn brand, often found at retailers like Walmart, making it a more accessible option.
How Novolin N Works
Novolin N's unique intermediate action is achieved by combining the insulin with protamine sulfate, a protein that slows down the absorption of the insulin into the bloodstream. This mechanism allows the insulin to have a more gradual and sustained effect compared to faster-acting versions. The typical action profile involves an onset of effect within one to four hours, with a peak occurring four to twelve hours after injection, and an overall duration of up to 24 hours. This prolonged effect helps provide a steady background or basal insulin level throughout the day and night.
Manufacturing and Supply Chain
Novo Nordisk operates significant manufacturing facilities around the globe to produce its wide range of diabetes products. Key insulin manufacturing locations include the massive plant in Kalundborg, Denmark, which is considered the world's largest insulin production site, as well as a large facility in Clayton, North Carolina. These facilities use advanced bioprocessing and recombinant DNA technology to produce human insulin crystals, which are then formulated, filled, and packaged.
Recent Changes in Insulin Production
In November 2024, Novo Nordisk announced a major change to its human insulin product line. Citing capacity constraints and the need to prioritize the manufacturing of its popular GLP-1 drugs for diabetes and obesity, the company is gradually phasing out human insulin pens globally. While Novolin N pens will be discontinued, the company will continue to offer human insulin in vials. This shift is in response to the growing demand for modern insulin analogs and GLP-1 medications, and it will impact patients who prefer the convenience of pen devices for administering their human insulin.
Comparing Novolin N to Modern Insulins
To understand where Novolin N fits in the modern landscape of diabetes care, it is useful to compare it with newer insulin products, particularly the rapid-acting analogs.

Pros and Cons of Novolin N
Pros of Novolin N
- Lower Cost: As an older-generation insulin, Novolin N is often more affordable and accessible, particularly for those who are uninsured or have limited coverage.
- Proven Efficacy: The use of NPH insulin has a long track record, having effectively managed blood sugar levels for many decades.
- Steady Background Coverage: Its intermediate action provides a consistent basal insulin level, which can be effective for managing blood glucose overnight.
Cons of Novolin N
- Less Predictable Peak: The pronounced peak of NPH insulin can lead to a higher risk of hypoglycemia if meals and activity are not carefully synchronized with its action.
- Risk of Hypoglycemia: The risk of low blood sugar is generally higher with NPH insulin compared to modern analogs due to its less flexible action profile.
- Phasing Out of Pens: The discontinuation of human insulin pens limits delivery options for patients who prefer them over traditional vials and syringes.
Conclusion
In summary, Novolin N is a key product from the respected Danish pharmaceutical company Novo Nordisk, a long-time pioneer in diabetes treatment. Its history and development are part of a century-long journey in insulin manufacturing that has seen immense advancements. While Novolin N remains an effective and affordable intermediate-acting insulin, patients and healthcare providers should be aware of the company's strategic shift towards modern analogs, which includes the gradual phasing out of human insulin pens. Novo Nordisk will continue to provide Novolin N in vials, but the change reflects the broader evolution in diabetes care toward more predictable and flexible treatment options. For specific treatment plans, patients should always consult with their healthcare provider.
