Tylenol, Otc Drug | featured news

Johnson & Johnson is revamping the troubled unit that makes Tylenol and giving it new leadership in an effort to fix quality problems that have prompted multiple recalls, according to people familiar with the matter.

A pair of studies suggests that the common painkiller acetaminophen -- better known as Tylenol in the U.S. -- may be fueling a worldwide increase in asthma.

Johnson & Johnson provided additional details on Friday about its two most recent recalls of Tylenol and other over-the-counter drugs, saying the actions on Thursday and June 15 involved a total of about 3 million bottles of the medicines.

The maker of Benadryl and Tylenol has added five lots of the popular over-the-counter drugs to its growing list of recalled products, McNeil Consumer Healthcare announced Wednesday in a written statement.
