A pharmaceutical company has issued a nationwide recall for Xanax after it determined that a "foreign substance" in the pills could be harmful to users of the anti-disease.
Mylan Pharmaceuticals said in the recall notice that there may be a chance of infection in the Alprazolam pills, sold by the brand name Xanax.
The recall affects tablets sold in the United States from July to August, according to the announcement.
The tablets concerned are designated by item number 8082708 and the national drug code is 0378-4003-05.
Mylan urged wholesalers to look for the potentially contaminated pills, and wrote in the notice that they would "immediately investigate inventory, quarantine and interrupt the distribution of these lots."
