The European label for the EC product Norlevo has been updated with two major changes. In keeping with current evidence, the new label now says that LNG EC works by interfering with ovulation, and the language about the possibility that LNG EC might prevent implantation of a fertilized egg has been removed. The second change is that the label now says that efficacy is reduced in women weighing 75 kg (165 lbs) and that it is ineffective for women weighing more than 80 kg (176 lbs). Mother Jones reported on the story here and The New York Times covered it here. The patient leaflet for the Irish product can be found here. Additionally, the Reproductive Health Technologies Project created a fact sheet of FAQ’s about weight and EC which can be accessed here.
