You may have heard emergency contraception referred to as the morning-after pill, or brand names such as Plan B and ella.

 

Emergency contraception is a term used for drugs taken after sex with the intent to prevent pregnancy. There are different brands of emergency contraception available, but the most common in America are Plan B One-Step and ella.

​

Many confuse emergency contraception with the abortion pill. The abortion pill terminates an established pregnancy. Emergency contraception, on the other hand, works primarily by preventing conception (though in some cases it has the potential to cause a very early abortion).

Plan B One-Step

Plan B One-Step also is referred to as the morning-after pill. It is intended to prevent pregnancy after a known or suspected contraceptive failure, unprotected intercourse, or forced sex. It contains large amounts of levonorgestrel, a progestin hormone found in some birth control pills. Plan B One-Step may work by preventing the egg and sperm from meeting by delaying ovulation. It won’t disrupt an implanted pregnancy, but may prevent a newly formed life from implanting in the uterus.

​

Plan B One-Step consists of one pill taken up to 72 hours after sex.

Side effects may include changes in your period, nausea, lower abdominal pain, fatigue, headache, and dizziness. If your period is more than a week late, you may be pregnant from a prior sexual encounter. Plan B One-Step should not be taken during pregnancy or used as a routine form of birth control.

​

There is evidence that Plan B One-Step use may increase the risk for ectopic (tubal) pregnancy, a potentially life-threatening condition. Women who have severe abdominal pain may have an ectopic (tubal) pregnancy, and should seek immediate medical attention.

​

It is reported that Plan B One-Step may prevent an average of 84% of expected pregnancies.

There is much that is unknown about Plan B One-Step including the following:

• dependence on the drug

• overdose

• the effect it could have on women who have not started their period

• the effect it could have on postmenopausal women

• liver disease

• kidney disease

• the way it interacts with other drugs

• its ability to cause a higher rate of pregnancy in Chinese women

 

ella

ella is an FDA-approved emergency contraceptive for use within 5 days of unprotected sex or contraceptive failure, which is why it is sometimes referred to as “the week-after pill.” It is estimated that taking ella will reduce the number of expected pregnancies from 5.5% to 2.2%.

​

Pregnancy from a previous sexual encounter should be ruled out before taking ella. It is to be used only once during a menstrual cycle.

ella may reduce the chance of pregnancy by preventing or postponing ovulation. It also may work by preventing a fertilized egg from implanting in the uterus, which is a very early abortion. ella is a chemical cousin to the abortion pill. Both share the progesterone-blocking effect of disrupting the embryo’s attachment to the womb, causing its death.

​

The most common adverse reactions of ella include headache, nausea, stomach (abdominal) pain, menstrual cramps, fatigue, and dizziness. Women who experience abdominal pain 3 to 5 weeks after using ella should be evaluated right away for an ectopic pregnancy.

​

Much is unknown about the drug, including its effect on women:

• who are under 18 or over 35 years of age,

• taking with other hormonal contraception,

• pregnant from a previous encounter,

• taking ella repeatedly during the same cycle, or

• taking while breast-feeding.
