Before taking any kind of morning after pill (Plan B, Ella), you should get information from a trusted source about what it is, how it could affect your health, and how it works. Comprehensive information is available when you visit Choices Women’s Clinic.

What Is the Morning After Pill?

The morning after pill is an intense dose of oral contraceptive, commonly trademarked under the names Plan B One-Step® or ellaOne®. The morning after pill has been approved by the FDA for use in the United States. The normal dosage for Plan B One-Step® is usually one tablet taken up to 72 hours (3 days) after sexual intercourse (usually after unprotected sex or contraceptive failure) to prevent pregnancy. The normal dosage for ellaOne® is one tablet within 5 days (120 hours) after sexual intercourse (usually after unprotected sex or contraceptive failure) to prevent pregnancy.

The morning after pill is chemically related but NOT the same as RU486 (also known as mifepristone), the abortion pill.

How Does The Morning After Pill Work?

The morning after pill works as an emergency contraceptive, principally by possibly preventing ovulation and fertilization. Additionally, it may inhibit implantation. It is ineffective once implantation has occurred.
