Introduction: The Dual Face of Insulin
Insulin, a life-saving drug for millions of people with diabetes, sits at the crossroads of scientific innovation, healthcare policy, and economic controversy. Since its discovery, insulin has transformed diabetes from a fatal disease into a manageable condition. However, the rising costs and accessibility issues surrounding insulin have sparked global debates on pharmaceutical pricing, ethics, and patient rights.
This blog takes a deep dive into the world of insulin, exploring its discovery, production, economic impact, and the ongoing fight for affordability and accessibility.

Section 1: The Birth of a Medical Miracle
A Discovery That Changed the World
The breakthrough discovery of insulin in 1921 by Frederick Banting and Charles Best was one of the greatest milestones in medical history. Before insulin, diabetes was a death sentence, with patients rarely surviving beyond a few months after diagnosis.
β Fact: In 1923, Banting and his team famously sold the insulin patent for just $1 to ensure its affordability, believing that “insulin belongs to the world, not to one company.”
The Rising Global Epidemic
Today, diabetes is a global health crisis, with numbers skyrocketing due to lifestyle changes and aging populations.
π Global Diabetes Statistics:
- In 1980, 108 million people had diabetes. By 2021, this number surged to 537 million (International Diabetes Federation, 2023).
- It is projected that by 2045, over 783 million people worldwide will have diabetes.
- 1 in 2 adults with diabetes remains undiagnosed.
With this explosion in diabetes cases, the demand for insulin has never been higherβand so has the debate over its cost.

Section 2: The High-Stakes Economics of Insulin
The Expensive Science Behind Insulin Production
Despite being discovered over a century ago, insulin remains one of the most expensive essential medicines in the world. But why?
π¬ Complex Production Process β Unlike simple chemical drugs, insulin is a biologic, meaning it is produced using living cells rather than synthetic chemical compounds. This makes its manufacturing costly, time-intensive, and highly regulated.
βοΈ Modern Advancements β The first insulin was derived from pigs and cows, but todayβs insulin is recombinant human insulin, manufactured using genetically modified bacteria or yeast.
π Fact: It takes 4-6 weeks to produce a single batch of insulin through modern biotechnological processes.
The Insulin Market: A Monopoly of Giants
The insulin industry is dominated by just three major pharmaceutical companies:
π’ Novo Nordisk (Denmark)
π’ Sanofi (France)
π’ Eli Lilly (USA)
These companies control over 90% of the global insulin market, giving them immense power over pricing.
π Fact: In the United States, the cost of insulin has tripled in the past 20 years, rising from $21 per vial in 1996 to over $300 per vial today (American Diabetes Association, 2023).
The Controversy of Pricing Tactics
The high cost of insulin is not purely due to production expenses. Major factors include:
π° Patent Evergreening β Companies slightly modify insulin formulas to extend patent protections, blocking cheaper generics.
π° Market Consolidation β With only a few manufacturers, there is little competition to drive prices down.
π° Lack of Regulation β Some countries, including the U.S., do not regulate insulin prices, allowing companies to set their own pricing strategies.
β Recent Developments: After growing public and political pressure, Eli Lilly, Novo Nordisk, and Sanofi announced price cuts of up to 70% in 2023 for some insulin products in the U.S. However, affordability remains a concern in low- and middle-income countries.

Section 3: Bridging the Gap in Insulin Accessibility
A World of Disparities
The availability and affordability of insulin vary dramatically across different regions.
π In Wealthy Nations:
- Insulin is widely available, but prices remain a major financial burden for uninsured or low-income patients.
- Many patients ration insulin, increasing the risk of severe complications.
- π Fact: In the U.S., 1 in 4 diabetics report rationing insulin due to cost (Harvard Medical School, 2022).
π In Low-Income Countries:
- Insulin is often unaffordable or completely unavailable.
- 50% of people worldwide who need insulin lack consistent access (WHO, 2023).
- Some African countries experience insulin markups of up to 300%, making it an unattainable luxury.
Fighting for Affordable Insulin
π₯ Patient Advocacy Groups: Organizations like T1International and the Diabetes Access Alliance fight for lower insulin prices through activism and lobbying.
βοΈ Government Regulations: Some countries, such as Canada and the UK, have price controls to keep insulin affordable.
π‘ Biosimilar Insulin: Newer biosimilar insulins (cheaper versions of brand-name insulins) offer potential cost savings.
π Example: The World Health Organization (WHO) prequalified the first biosimilar insulin in 2021, paving the way for more affordable options worldwide.
Β
Conclusion: The Future of Insulin Pricing and Accessibility
The story of insulin is a complex intersection of science, economics, and ethics. While it remains an indispensable lifeline for millions, its skyrocketing costs and limited access have created a global crisis.
Key Takeaways:
πΉ Insulin is a life-saving but costly biologic drug, with prices tripling in two decades in some regions.
πΉ The insulin market is controlled by three major players, allowing pricing control and limited competition.
πΉ Global disparities mean insulin is abundant in some countries but scarce in others.
πΉ Regulatory actions, biosimilar production, and activism are pushing for greater affordability and accessibility.
As the fight for affordable insulin continues, it is crucial to ensure that this life-saving medication remains a right, not a privilege. The world needs sustainable solutions to make insulin affordable for allβregardless of geography, income, or healthcare system.
