Manufacturing & Quality

Making Safe, High-Quality Medicine

We strive for a culture of quality throughout our company, and as a result, quality has become synonymous with the Lilly name.

We are a leader in developing advanced quality systems that influence every area of our business, from product development to manufacturing, and from internal review processes to sales and marketing. Quality extends far past the manufacturing floor; it’s everywhere at Lilly.

Lilly’s standard of excellence in pharmaceutical manufacturing began in 1876 with founder Eli Lilly’s revolutionary commitment to producing quality medicines that would improve people’s lives. In 1923, Lilly became the first company to manufacture commercial quantities of insulin, which paved the way to make this lifesaving medicine available to people with diabetes.

Today, Lilly Global Manufacturing continues to produce essential medicines with the help of more than 8,000 employees that span across 14 manufacturing sites worldwide. Hand in hand with a large network of global external manufacturing partners, we supply medication to nearly 125 countries.

Lilly is committed to manufacturing medicines that meet or exceed the applicable standards of safety, quality, value and environmental stewardship.
