Bloomberg: How Marketing Turned EpiPen Into A Billion-Dollar Business In a 2007 purchase of medicines from Merck KGaA, drugmaker Mylan picked up a decades-old product, the EpiPen auto injector for food allergy and bee-sting emergencies. Management first thought to divest the aging device, which logged only $200 million in revenue. Then Heather Bresch, now Mylan's chief executive officer, hit on the idea of using old-fashioned marketing in part to boost sales among concerned parents of children with allergies. That started EpiPen, which delivers about $1 worth of the hormone epinephrine, on a run that's resulted in its becoming a $1 billion-a-year product that clobbers its rivals and provides about 40 percent of Mylan's operating profits, says researcher ABR|Healthco. EpiPen margins were 55 percent in 2014, up from 9 percent in 2008, ABR|Healthco estimates. (Koons and Langreth, 9/23)
