IMPORTANT INFORMATION ABOUT PLAN B ONE-STEP

Plan B One-Step (levonorgestrel) 1.5 mg tablet is the first FDA-approved emergency contraceptive to be available over the counter for anyone who needs to purchase it. Plan B One-Step helps prevent pregnancy when taken as directed within 72 hours (3 days) after birth control failure or unprotected sex. It must be taken as soon as possible after unprotected intercourse. The sooner it’s taken, the better it works.

Plan B One-Step contains levonorgestrel, a hormone that has been used in many birth control pills for decades—just at a higher dose. It is a backup method of helping to prevent pregnancy and should not be used as regular birth control because it is not as effective.

If Plan B One-Step is taken as directed, it can significantly decrease the chance that a woman will get pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant after taking Plan B One-Step.

Plan B One-Step works in a similar way to birth control pills, primarily by:

  • preventing ovulation

It may also work by:

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

It will not affect an existing pregnancy.

  • menstrual changes
  • nausea
  • lower stomach (abdominal) pain

Some women taking Plan B One-Step will have menstrual changes such as spotting or bleeding before their next period. For some women, their next period may be heavier or lighter, or they may have a period that is early or late.

A pregnancy test should be given if a period is more than 1 week late.

If the patient vomits within 2 hours of taking the Plan B One-Step tablet, the patient should immediately contact a healthcare professional to find out if she should repeat the dose.

It is up to the healthcare professional's clinical judgment whether or not the patient should repeat the one-tablet dose.

Severe abdominal pain may be a sign of an ectopic pregnancy, for which immediate medical attention is required.

Plan B One-Step should only be used in emergencies, but there is no medical reason why it can't be used more than once. Plan B One-Step doesn't provide long-term protection against future pregnancy — it only works to help prevent the one incident for which it is taken and should not be used as regular birth control because it is not as effective.

Drugs or herbal products that induce progestin-metabolizing enzymes, including CYP3A4, may decrease the plasma concentrations of progestins, and decrease the effectiveness of progestin-only pills.

Some drugs or herbal products that may decrease the effectiveness of progestin-only pills include:

  • barbiturates
  • bosentan
  • carbamazepine
  • felbamate
  • griseofulvin
  • oxcarbazepine
  • phenytoin
  • rifampin
  • St. John’s wort
  • topiramate
  • certain HIV/AIDS medications

Significant changes (increase or decease) in the plasma levels of progestin have been noted in some cases of coadministration with HIV protease inhibitors or with nonnucleoside reverse transcriptase inhibitors (NNRTIs).

Consult the labeling of all concurrently used drugs to obtain further information about interactions with progestin-only pills or the potential for enzyme alterations.
