Allergan sues Pfizer over opioid litigation costs

Aug. 2, 2018

Allergan has sued Pfizer in the hopes of covering the cost of potential damages Allergan faces because of the hundreds of lawsuits that allege it marketed an opioid acquired from Pfizer deceptively.

In a lawsuit filed in federal court in Ohio, Allergan is arguing that the deluge of lawsuits it faces stem from Pfizer's improper marketing and sale of Kadian in the time leading up to Allergan acquiring the rights to the drug in 2008.

More than 1,000 lawsuits are consolidated before U.S. District Judge Dan Polster in Cleveland that claim opioid makers and drug wholesalers created a public-health crisis through their painkiller marketing.

Allergan argues that the majority of the lawsuits it is facing relate to Kadian issues that occured before it acquired the drug from Pfizer.
