Petitions signed by more than 700,000 people demanding to drop the price of a lifesaving drug made it to the doorstep of the company that makes it.

Petitions signed by more than 700,000 people demanding to drop the price of a lifesaving drug made it to the doorstep of the company that makes it.

Protestors from Public Citizen dropped off the petitions to Mylan's corporate offices just outside of Pittsburgh on Tuesday. The drug maker is under fire for a drastic price hike in the cost of its EpiPens, which could save the life of a person who is having an allergic reaction. The cost of a two-pack of EpiPens jumped from around $100 to $600 in just a few years.

Mylan responded to criticism by rolling out rebates and discounts, and then a generic version.
