There are many misconceptions about emergency contraception, so it’s important for your patients to know that Plan B® One-Step works similar to regular birth control pills; it simply contains a larger dose of the hormone levonorgestrel. Plan B® One-Step works primarily by

  • Preventing ovulation
  • Possibly preventing fertilization by altering tubal transport of sperm and/or egg
  • Altering the endometrium, which may inhibit implantation

Plan B® One-Step is not effective once the process of implantation has begun. It will not affect an existing pregnancy or harm a developing fetus.

Plan B® One-Step should be taken as soon as possible. When taken as directed— within 72 hours (3 days) after unprotected intercourse or contraceptive failure — approximately seven out of eight women who would have gotten pregnant will not become pregnant after taking Plan B® One-Step.1
