The Gabapentin lawsuit involves legal actions against pharmaceutical companies, primarily Pfizer and its subsidiary Parke-Davis, relating to the marketing and promotion of gabapentin (brand name Neurontin) for off-label uses not approved by the U.S. Food and Drug Administration (FDA). These lawsuits allege that the companies engaged in deceptive marketing practices that led to widespread prescriptions of gabapentin for conditions lacking scientific support, causing unnecessary healthcare costs and exposing patients to potential risks.
Background of the Gabapentin Lawsuit
Gabapentin was approved by the FDA in 1993 as an adjunctive treatment for partial seizures in epilepsy and for postherpetic neuralgia. However, beginning in the mid-1990s, Parke-Davis aggressively marketed the drug for numerous off-label uses such as bipolar disorder, migraine, and other types of pain without proper FDA approval. This off-label promotion arguably violated federal law, leading to multiple lawsuits and a major whistleblower suit filed in 1996 by a former employee, David Franklin.
The litigation culminated in a notable settlement in 2004 where Pfizer agreed to pay $430 million to resolve civil liabilities and criminal charges involving off-label marketing of Neurontin. Despite the settlement, questions about the drug’s efficacy for off-label indications and ongoing prescribing practices persisted.
Parties and Incident Context
The plaintiffs include federal and state governments seeking reimbursement for Medicaid and Medicare expenses, private insurers, healthcare providers, and patients claiming harm. Defendants mainly comprise Pfizer Inc., Warner-Lambert Company, Parke-Davis division, and their affiliates. The legal battles revolve around allegations of fraudulent scientific evidence, improper marketing strategies, and suppression of negative clinical trial results.
