Plan B is a morning-after pill under the form of a single tablet that you can take to prevent pregnancy if you have had unprotected sex or suspect that your birth control failed. You can take Plan B if: your partner’s condom broke, you lost track of your “safe days”, your partner did not pull out in time, you missed one or more doses of your regular birth control, your diaphragm slipped out of place, you were forced to have sex. Plan B contains levonorgestrel, which is a synthetic (man-made) version of the natural hormone progesterone, which is produced by the ovaries. Similar to birth control pills containing levonorgestrel at a low dose, Plan B contains levonorgestrel at a higher dose (1.5mg), and works by delaying or stopping the release of an egg from the ovary. Plan B is meant as an emergency contraceptive only and therefore does not replace a regular birth control method. It is very important that you use regular birth control the next time you have sex. There are many different methods of birth control available, so talk to your physician about your options and find out which one is best for you. Plan B does not affect in any way your chances of getting pregnant in the future. However, please note that Plan B is not indicated for termination of an existing pregnancy (abortion) and does not protect you against sexually transmitted infections (STI) and HIV. Do not use Plan B if you know or think you are pregnant.
Plan B contains levonorgestrel, a synthetic (man-made) version of the hormone progesterone, which is produced by the ovaries. Plan B contains a higher dose of levonorgestrel (1.5mg) than birth control pills, which also contain levonorgestrel at a low dose. Levonorgestrel works by delaying or stopping the release of an egg from the ovary.
Plan B Step-One is most effective when taken soon after having unprotected sex; its efficacy will subsequently begin to decrease the longer the interval between intercourse and ingesting the pill. If taken within 24 hours, levonorgestrel pills can reduce the risk of pregnancy by up to 95%; after around 72 hours, this will drop to around 89%. Therefore, it is important that the pill is taken as soon as possible after sex, for it to have optimum effect.
Plan B One-Step is intended for women who have had unprotected sex within a period of 72 hours and, therefore, are at risk of falling pregnant. There are several circumstances under which a woman is at risk of falling pregnant, these include:
Plan B contains the active ingredient levonorgestrel at a concentration of 1.5mg.
Plan B also contains the following inactive ingredients: colloidal silicon dioxide, corn starch, lactose monohydrate, magnesium stearate, potato starch, and talc.
Take Plan B One-Step 1.5mg tablet orally (by mouth) as soon as you can within 72 hours of unprotected sex or failed contraception. The sooner you take Plan B, the better it works. You can take Plan B during your menstrual cycle, day or night, with or without food. Do not take more than one dose of any kind of morning-after pill as it might make you feel nauseous and will not increase your protection against pregnancy anyway.
If for any reason you throw up within 2 hours of taking Plan B, contact your doctor or healthcare provider immediately to discuss whether to take another dose.
If you had unprotected sex more than 72 hours ago, then Plan B Step-One will no longer be effective in preventing a pregnancy. In this case, you will have to either take Ella – an alternative emergency contraception – or have an IUD inserted in your uterus. Both methods can be employed up to 5 days after unprotected sex to effectively protect against an unwanted pregnancy.
Common side effects include:
For some women it may be that their next period comes earlier or later than expected, heavier or lighter than usual. They may also experience changes such as spotting or bleeding before their next period. Take a pregnancy test if your period is more than a week late.
If these symptoms persist or cause distress, talk to your doctor.
Seek medical attention if you experience severe lower abdominal pain 3 to 5 weeks of taking Plan B in order to evaluate for an ectopic pregnancy, which is when a fertilized egg attaches itself outside of the womb, usually in one of the fallopian tubes.
Seek medical attention if you experience an allergic reaction to Plan B (hives, difficulty breathing, swelling of face/tongue/throat).
Plan B is contraindicated in the case of known or suspected pregnancy, however Plan B is not an abortion pill.
Some drugs or herbal products may interfere with the effectiveness of Plan B. Avoid using Plan B at the same time as the following drugs or herbal products:
There are several options of emergency birth control available to women who have had unprotected sex. Plan B, and other pills containing generic levonorgestrel, are most effective when taken within 3 days of having sexual intercourse; however, there are alternatives, which can work up to 5 days after sex.
Ella contains ulipristral acetate, which works by altering the body’s progesterone levels to delay or prevent ovulation, and is just as effective when taken on day 5, as it is on day 1. This option is best for women who have had sex during the time of ovulation, when the risk of falling pregnant is the highest. It may also be more effective for women who are overweight or obese – with a BMI of 26 or more.
While Plan B – and other emergency contraception – is effective in preventing a pregnancy, it should not be used as a substitute for regular birth control. As the name indicates, such contraception should only be used in emergencies, as opposed to on a consistent basis. Regular contraception has increased efficacy, fewer side effects, and is less expensive than the morning after pill.
The intrauterine device (IUD) is another viable option for women who require emergency contraception. This is a small, t-shaped device, made of copper and plastic, that is inserted into the uterus to prevent an egg from being fertilized. It may be inserted up to 5 days after unprotected sex and is proven to be around 99% effective. Unlike the morning after pills, an IUD can safely be left in as an ongoing contraceptive method for several years, and will not interact with any other medications.
Always inform your doctor of the drugs or herbal products you are taking as these may interfere with the effectiveness of Plan B. Avoid using Plan B at the same time as the following drugs or herbal products: Barbiturates, Bosentan, Carbamazepine, Felbamate, Griseofulvin, Oxcarbazepine, Phenytoin, Rifampin, St. John’s Wort, Topiramate.
If you think you may already be pregnant, you must not take any emergency contraception. Although the hormones in Plan B, or any other levonorgestrel pills, will not harm the fetus, it will not be effective after conception, as it is intended to prevent a pregnancy that has not yet occurred.
Emergency contraception can sometimes cause nausea and/or vomiting. If you throw up within 2 hours of taking Plan B, then you need to consult your doctor or pharmacist, as you may need to take a second dose. If you throw up more than 2 hours after taking the pill, then it should still be effective – you do not need to do anything.
Plan B does not cause a miscarriage or abortion; its properties are very different to RU-486 – the abortion pill. Because Plan B will not prevent the development of an egg that has already been fertilized and implanted in the uterus, it will not work if it is taken once you are already pregnant.
Plan B can cause some changes to your menstruation. You may find that your next period, after taking Plan B, comes as much as a week earlier or later than usual; you may also notice that your blood flow is significantly heavier, with more days of bleeding. Such experiences are completely normal after taking emergency contraception and should not be a cause for concern. If, however, your next period does not come through at all, then you should take a pregnancy test.
While manufacturers advise that you only take Plan B – and other generic levonorgestrel – once, you may take it more than once during your monthly cycle without it causing any serious side-effects. However, if you find that you are often relying on it, you should think about taking regular birth control, as it is more effective.
