European morning after pill ineffective with overweight women
Researchers have found the European version of the morning after pill does not work to prevent pregnancy in overweight women.
The drug starts losing effectiveness in women who weigh more than 165 pounds, and becomes completely ineffective in women who weigh more than 176 pounds.
That drug is identical to America's Plan B One Step pill.
The FDA said it is reviewing the information, and will determine if it needs to change the pill's labeling.
