Before taking the Morning After Pill, you should understand what it is, what it could mean to your health and how it works. Call for an appointment and one of our staff will be happy to discuss it with you and advise you on your options.

What is it?

The “Morning After Pill” is a large dose of oral contraceptive. For use within 72 hours (3 days) after sex, but it is more effective if taken sooner. It is NOT the same as RU-486.

How does it work?

Plan B is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization. In addition, it may inhibit implantation. It is not effective once the process of implantation has begun.

Things to consider

  • Emergency contraception is not effective if a woman is already pregnant.
  • Plan B does not protect against HIV infection (AIDS) and other sexually transmitted diseases.
  • The most common side effects in the Plan B clinical trial were nausea, abdominal pain, fatigue, headache, and menstrual changes.
  • The manufacturer warns that Plan B is not recommended for routine use as a contraceptive.
