The EpiPen was invented in the 1970s by a biomedical engineer, Sheldon Kaplan, who was searching for a way to treat allergic reactions quickly.
What he came up with was the EpiPen we know today: a pen-like device that delivers a premeasured dose of the hormone epinephrine in emergency situations. The device is ubiquitous in our country, carried by those with asthma or life-threatening allergies.
And since 2007, a drug company called Mylan has quietly hiked EpiPen's price by 400 percent.
