WASHINGTON (Reuters) - Health officials are weighing stricter labels on the widely used new generation of birth control pills, based on data showing they may put women at a higher risk of dangerous blood clots.
U.S. Food and Drug Administration staff reviewed studies comparing an older generation of birth control with newer pills that contain the compound drospirenone, such as Bayer AG's popular Yaz and Yasmin.
In a report released on Tuesday, the reviewers said the body of evidence shows conflicting data on a link between pills containing drospirenone and blood clots, but the link could not be ruled out either and that fact may warrant a new label.
"Because of the consistency in recent reports for an increased risk, product labeling should reflect that very real possibility," they said. A panel of outside experts advising the FDA is due to vote on the labels on Thursday.
