The subpoenas, which came from the U.S. attorney's offices in Philadelphia, Boston and San Francisco, are associated with investigations into the sales and marketing of Janssen's Risperdal, Ortho-McNeil's Topamax and Scios' Natrecor. All three manufacturers are subsidiaries of Johnson & Johnson.
"The subpoenas request information regarding Johnson and Johnson's corporate supervision and oversight of these three subsidiaries, including their sales and marketing of these drugs," J&J said in a statement.
The company said it will cooperate with the subpoena requests.
