A recall of Mylan's popular EpiPen emergency allergy medication has expanded to the U.S.
The recall began last week, but the Food and Drug Administration announced Friday that it would also apply to the U.S. 13 different lots of the EpiPen injectors were recalled for a defective part that could prevent the injector from working, potentially putting lives in danger.
The FDA said the number of affected units was small. The lots affected were sold between Dec. 17, 2015 and July 1, 2016.
Among the 13 affected lots are two EpiPen Jr. lots. The EpiPen Jr. is the children's version of the injector. Units affected by the recall can be replaced for free by calling 877 650 3494.
Mylan, creator of the EpiPen, fell under harsh scrutiny last year after the price of an EpiPen spiked nearly 600 percent since it bought the medicine in 2007. Since that time it has announced a cheaper generic version and agreed to pay $465 million to settle a lawsuit with the Department of Justice.
The FDA announced last year it would fast-track EpiPen competitors, helping them get to market sooner.
