The FDA issued a warning to nursing mothers to be wary of the serious side effects of the painkiller codeine in their babies after scientists discovered that a significant number of women carry a gene that leads to rapid metabolizing of the codeine into morphine, which is then excreted into breast milk. While the agency doesn't discourage women who take codeine from breast-feeding, it urges them to contact their health care professional if they or their babies show any signs of overdose, such as sleepiness.
