EpiPens distributed in the United States are being recalled because they do not work, according to the U.S. Food and Drug Administration (FDA).

According to WCVB 5, Mylan announced Friday the recall is being conducted as a result of two reports from outside the U.S. During those two instances, the device would not activate. The company stated that the malfunction is because of a potential defect in a supplier component.

The defect makes its difficult for the EpiPen to work during emergencies and could have significant health consequences for someone who is experiencing an allergic reaction.

Mylan said it will replace recalled EpiPens for free. To return your product, you can contact Stericycle at 877-650-3494. Any additional questions should be made to Mylan Customer Relations at 800-796-9526 or customer.service@mylan.com.
