Morning-after pill may be less effective for heavier women

- Mother Jones, which first reported the expected change Monday. Norlevo is sold in in Europe, Australia, India, Canada and other countries worldwide.
Norlevo contains a synthetic hormone known as levonorgestrel, which is also the main ingredient in Plan B One-Step, the brand name of the one-pill emergency contraception available in the United States. When taken with 72 hours after sex, both pills delay or prevent ovulation or block fertilization of an egg.
The Food and Drug Administration is investigating whether similar label changes are needed for emergency contraception in the U.S.
“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,” said Erica Jefferson, deputy director for the FDA office of media affairs. “The agency will then determine what, if any, labeling changes to approved emergency contraceptives are warranted."
The original approval of Plan B for use in the U.S. did not include weight-related assessment, Jefferson added.
Studies have shown that hormone-based birth control pills and patches can be less effective in heavier women. A study published in the journal Contraception in 2011 found that obese women who used a levonorgestrel-based product were more than four times as likely as normal weight women to become pregnant. Obese women who used a product containing ulipristal acetate, the compound used in Ella, a different type of morning-after pill, were nearly three times as likely as normal weight women to become pregnant. The research was conducted by an international team of researchers looked at data from nearly 4,000 women who had taken emergency contraception after unprotected intercourse.
