The Morning-After Pill is any type of oral hormonal birth control taken after unprotected intercourse or a known or suspected contraceptive failure (e.g. a broken condom).
Is Plan B® Effective?
Plan B® is reported to reduce the chance of pregnancy by 60-94% (i), depending on which study is considered. It is important to note that these figures are based on estimates of when ovulation may have occurred.
How is Plan B® Administered?
Plan B® is administered in two tablets: the first must be taken within 72 hours of unprotected sex and the second 12 hours after the first tablet (ii).
Is Plan B® One-Step Effective?
One study conducted by Plan B® One-Step found that 84% of expected pregnancies were prevented.(iii) The makers of the drug claim 7 out of 8 women who would have gotten pregnant did not (iv). These figures are based on the timing of intercourse with regard to each woman’s menstrual cycle.
How is Plan B® One-Step Administered?
Plan B® One-Step is administered in one tablet and must be taken within 72 hours of unprotected sex (v).
Should I Take the Morning-After Pill?
Many times women panic after having unprotected sex and rush to take the Morning-After Pill. However, women can only become pregnant on certain days of the month – around the time that you ovulate. Typically, there are only about three to five days a month in which pregnancy can occur. Many women take the Morning-After Pill during a time when they are not fertile meaning that they could not become pregnant. Taking the Morning-After Pill during a time when you cannot become pregnant needlessly exposes you to large doses of hormones.
How Does it Work?
Plan B®vi and Plan B® One-Step(vii) are believed to work in one of 3 ways:
- It may prevent or delay ovulation (release of egg from ovary).
- It may affect the sperm and tube transport to prevent the egg from being fertilized.
- It may alter the uterine lining which prevents the fertilized egg from implanting, resulting in an early abortion.
There is no way to know which way the drug is working in any one person.
Can the Morning-After Pill Cause an Abortion?
That depends upon how you define ‘life’. The scientific reality is that the instant a human egg and sperm unite (fertilization), the newly formed being contains the full complement of DNA in which hair and eye color, gender and all other physical characteristics are determined. During its journey down the fallopian tube, the fertilized egg is actively growing and dividing. It will then implant in the uterine lining where it will continue to grow.
A number of years ago, some in the medical community arbitrarily decided to redefine the beginning of pregnancy as when implantation occurs. Clearly, this contradicts the known facts about when life itself begins, and that is at fertilization. So, one of the ways that Plan B® may work is to alter the uterine lining so that a fertilized egg may not be able to implant and grow (viii). Taking Plan B® after the sperm has fertilized the egg, may interfere with the fertilized egg’s implantation in the uterus which some would consider a very early abortion.
Will it have an Effect on My Period?
It is possible the Plan B® One-Step will affect your period and your cycle. The most common adverse reaction is heavier menstrual bleeding (ix). If your period is delayed for more than one week, pregnancy should be considered(x). Following use of Plan B® One-Step rapid return of fertility is likely (xi).
Should I see a Doctor?
It may be indicated to have a medical examination after taking Plan B® One-Step.
Does the Morning-After Pill have Side Effects?
Plan B® includes side effects such as nausea, abdominal pain, fatigue, headache, heavier menstrual bleeding, lighter menstrual bleeding, and dizziness (xii).
Plan B® One-Step (xiii) includes side effects such as heavier menstrual bleeding, nausea, lower abdominal pain, fatigue, headache, dizziness, breast tenderness, and delay of period.
Does the Moring –After Pill have Risks?
Forms of the Morning-After Pill that contain the hormone estrogen carry the potential risks associated with that drug. These include: blood clots, stroke and heart attack.
There is some evidence that the Morning-After Pill may put a woman at increased risk for an ectopic pregnancy (a pregnancy occurring outside the uterus) (xiv)
It is very important to be aware of the signs and symptoms of an ectopic pregnancy because it can be life-threatening. Women who have an ectopic pregnancy may experience, irregular vaginal bleeding, abdominal and/or pelvic pain and cramps, shoulder pain and dizziness (xv). Many of these symptoms are similar to the potential side effects associated with the use of the Morning-After Pill. It is critical that anyone who has these symptoms be evaluated by a physician.
Could I Already be Pregnant?
Yes. If you are routinely experiencing unprotected sex, you may already be pregnant from an earlier sexual encounter. This is why taking a pregnancy test before considering Plan B® and Plan B® One-Step makes sense. Women who have a known or suspected pregnancy should not take the pills, according to the manufacturers of Plan B® (xvi) Plan B® One-Step (xvii). Please call us for a free and confidential pregnancy test.
Is the Morning-After Pill for someone my Age?
It is unknown whether or not Plan B® or Plan B® One-Step is safe and effective for women under the age of 16 (xviii). It is unknown whether or not Plan B® One-Step is safe and effective for women less than 17 years of age(xix).
What is Unknown about Plan B® and Plan B® One-Step?
There is much that is unknown about the drug such as:
- Plan B®’s effect on women under the age of 16(xx)
- Plan B® One-Step’s effect on women less than 17 years old (xxi)
- Its effects when interacting with other drugs (xxii,xxiii)
- Its effects on women with certain types of medical conditions (xxiv,xxv)
- Plan B®’s effects on women’s ovulation and fertility (xxvi)
- Effects on fetal growth and development (xxvii,xxviii)
Additionally, Plan B® or Plan B® One-Step are not recommended for routine use(xxix,xxx) but the makers of Plan B® have not defined what they consider to be “routine”. There has not been any research on drug abuse and dependence on Plan B® (xxxi) or Plan B® One-Step (xxxii) . There is, also, no information on overdose of Plan B® (xxxiii) or Plan B® One-Step (xxxiv) .
