The cost of two EpiPens was $100 in 2009. In 2016, the cost was $600.
The company that produced EpiPens, Mylan, blamed health insurance for the high price.
In 2018, the Food and Drug Administration approved a generic form of EpiPens, according to CNN.
Manufacturing problems have also contributed to patients who need the life-saving medication, but cannot get it, according to Consumer Reports.
But there are new treatments coming to market.
Novartis has released Symjepi, which is a new type of injector. Walgreens also offers a third type called Auvi-Q that is no cost to those who have insurance. If a patient is in need of Auvi-Q, but isn't near a Walgreens, the company that makes it, Kaelo, will ship it to them at no cost, according to Consumer Reports.
