    Beginning in 2014, the morning after birth control pill Norlevo will come with a warning that it is not effective for women who weigh more than 176 pounds, and is less effective for women who are 165 pounds or heavier.

    The Norlevo brand birth control pill is available in Europe, Australia, India, Canada and other countries around the world, and has the same active ingredient as the Plan B One-Step emergency contraceptive pill that is available in the United States.

    But the Plan B pill doesn’t have a warning about the effectiveness as it relates to how much the person taking the synthetic hormone weighs.

    Erica Jefferson, deputy director for the FDA office of media affairs said: “The FDA is currently reviewing the available and related scientific information on this issue, including the publication upon which the Norlevo labeling change was based. The agency will then determine what, if any, labeling changes to approved emergency contraceptives are warranted.”

    Warnings on the Norlevo label are based on a 2011 study that found obese women were more than four times as likely to still get pregnant after taking the emergency contraceptive than women involved in the study who were a healthy weight.
