Assemblyman Anthony Brindisi calls the dramatic price hike for EpiPens "nuts" and is calling for a state investigation.

He's written to Attorney General Eric Schneiderman and State Health Commissioner Howard Zucker, asking them to investigate the steep increase in the price of the EpiPens used by thousands of New Yorkers.

Brindisi says he's concerned that the price hike threatens the health and safety of many students headed back to school whose families will have trouble affording EpiPens.

The Assemblyman calls EpiPen manufacturer Mylan's solution to offer  a co-pay discount card inadequate.  He says it still leaves patients holding the bag for over $300 in costs for the product.

The price of EiPens has increased from $100 in 2009, but now costs more than $600.
