(CNN) – Mylan Pharmaceuticals is recalling a single lot of anti-anxiety medication commonly sold as Xanax.
Xanax is the brand name for the anti-anxiety medication, alprazolam.
The company believes the recalled product could potentially contain a foreign substance, causing a risk of illness.
The voluntary recall includes bottles containing 500 half milligram tablets.
Mylan says the pills were distributed in the U.S. between July and August.
