LONDON (AP) The European Medicines Agency says it has started a review of emergency contraceptives to see if they are less effective in overweight women.

In November, French drug maker HRA Pharma announced its morning-after pill didn't work in women heavier than 80 kilograms (176 pounds) and changed its labels to warn patients after consulting with European regulators.

In a statement on Friday, the EMA said it would evaluate new data suggesting that a high body weight could compromise the effectiveness of the morning-after pill.

HRA Pharma's Norlevo contains levonorgestrel, the same active ingredient in other medicines including ellaOne, Levonnelle and Levodonna.

The morning-after pill can be taken up to 72 hours after unprotected sex. It works by preventing ovulation or fertilization of an egg.
