Allergan Inc. (AGN) (AGN), the maker of the wrinkle treatment Botox, received a U.S. government subpoena over its gastric banding device for obesity. Allergan received the subpoena from the Department of Health and Human Services’s Inspector General this month, the company reported today in a filing. Bonnie Jacobs, a spokeswoman for Irvine, California-based Allergan, acknowledged the subpoena but declined to comment further. Allergan generated $203.1 million of its $5.42 billion revenue (AGN) last year from devices for obesity. The company acquired the product, called Lap-Band, in 2006 with its purchase of Inamed Corp. The adjustable silicon band helps people lose weight by reducing the amount of food their stomachs can hold.
