Be careful, girls – if you’re voluptuous, it turns out that the morning-after pill may not work so well on you.
According to a news report, French scientists found that the specific morning-after contraceptive pill sold in France began losing effectiveness in women who weighed about 75kg, and did not work at all in women heavier than 80kg .
European health regulators had ordered a label change for the emergency contraceptive product sold by French company HRA Pharma under the brand name Norlevo, requiring it to include the drug’s diminishing effectiveness based on weight.
The US Food and Drug Administration is looking into whether other morning-after contraceptive pills fail to work in women over a certain weight. It will decide later whether to add a warning to the drug’s label.
