Heather Bresch, CEO of Mylan Pharmacueticals, will face lawmakers' questions Wednesday about the company's steep price hikes for the company's life-saving EpiPen auto-injector.
Mylan, the maker of EpiPen, says it will sell a generic version for $300 for a two-pack, a price that consumer advocates say is still too high. The device is used to treat severe allergic reactions.
