Morning-After Pill May Not Work for Heavy Women

The European Medicines Agency says it has started a review of emergency contraceptives to see if they are less effective for 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.
