Historical sales performance of Viagra

Viagra, Pfizer's blockbuster erectile dysfunction drug, was launched in 1998. It experienced rapid growth, achieving $2 billion in annual sales by 2008. In its first quarter, Viagra generated $400 million in revenue for Pfizer, and later produced annual sales of around $1.8 billion.

Peak sales period (2012)

Viagra was once one of Pfizer's most successful drugs, generating over $1 billion in sales every year for 17 years.

Its sales reached a peak of $2.1 billion in 2012.

Post-peak period (2016, 2019)

Despite its initial success, Viagra's sales started to decline, reaching $1.6 billion in global sales in 2016. By 2019, the drug's revenue had further decreased to about $500 million.

Patent protection expiration and its impact on sales

Viagra's patent protection expired outside the U.S. in 2012, which has led to a steady decrease in sales over the past seven years. The U.S. market for erectile-dysfunction drugs has also been shrinking, adding pressure on Viagra's sales performance.

Recent trends in Viagra sales (2020)

In 2020, Viagra still held the highest revenue share in its segment, accounting for 57.8% of the market. However, some analysts projected that sales of Cialis, a competing drug, would fall below $1 billion in annual sales by 2019.

Global sales figures for Viagra

Taking into account the various historical sales figures and trends, it can be estimated that Pfizer's Viagra has generated tens of billions of dollars in total revenue since its launch in 1998. However, an exact figure is difficult to ascertain due to fluctuations in annual sales and market dynamics.
