After the national outrage over EpiPen’s increase of the price of a box epinephrine injections to $609 last August, Mylan, the manufacturer, promised to live up to its motto of doing what’s right, not what’s easy. But, writes Charles Duhigg in The New York Times, last week regulators said the company had most likely overcharged Medicaid by $1.27 billion for EpiPens and the retail price of a box was still $609. The device contains about $1 of the drug epinephrine.
