John Kopchinski is a former sales representative for Pfizer Inc., a prominent pharmaceutical company. He gained significance in whistleblowing when he exposed the company's illegal marketing practices in 2009. As a West Point grad, Kopchinski was hired by Pfizer Inc. in 1992 as a sales rep after he left the Army. Kopchinski was one of the key whistleblowers in a case against Pfizer, which resulted in the company pleading guilty to criminal charges and paying a record-breaking $2.3 billion in fines. Kopchinski's whistleblowing was pivotal in uncovering Pfizer's off-label promotion of Bextra, an anti-inflammatory drug, for uses and dosages not approved by the FDA. His courageous actions shed light on the unethical practices within the pharmaceutical industry and demonstrated the importance of whistleblowing in holding corporations accountable for their actions.
