New Mexico Attorney General Hector Balderas' office has sent an investigatory letter requesting information from the manufacturer of life-saving EpiPen.
That's the brand name of an auto-injector of synthetic adrenaline that treats severe allergic reactions to insect bites and stings and foods like nuts and eggs.
People usually keep multiple EpiPens handy at home, school or work. But the syringes prefilled with the hormone epinephrine expire after one year.
The list price of EpiPens has grown to $608 for a two-pack, an increase of more than 500 percent since 2007.
Families who rely on multiple EpiPens have lashed out at the pharmaceutical company Mylan.
In a statement Wednesday, Balderas says his office is doing everything in its power to make sure New Mexico children and families can afford life-saving medications.
