(Reuters) - An Ohio woman on Tuesday filed a proposed class action lawsuit against Mylan Pharmaceuticals Inc in an Ohio county court, claiming sharp price hikes for the company's EpiPen device violated the state's consumer protection law.
Mylan has raised the U.S. price of the EpiPen, which is used to treat life-threatening allergies, from less than $100 when it acquired the product in 2007 to more than $600, drawing criticism from parents, consumer groups and U.S. politicians.
New York's attorney general said on Tuesday he is investigating whether Mylan violated antitrust laws in its contracts to provide EpiPens to some school systems.
