- Some types of EC (Plan B One-Step™and Next Choice®) are available over-the-counter (without a prescription), for young women.
- A brand of EC called, ella™ (Ulipristal acetate) requires a prescription from a health care provider.
Emergency contraception (EC) is a backup method of birth control for preventing pregnancy after unprotected sex. Even though it’s commonly called the “morning-after pill,” it can actually be used within 5 days (120 hours) of unprotected intercourse. However, the sooner you take it, the more likely it will work.
When should a women use emergency contraception?
Emergency contraception (EC) should be used if:
- You had unprotected sex, which means your partner did not use a condom and you are not using another method of birth control (pill, IUD, Nexplanon, etc).
- You forget to take your birth control pills (and you’ve been having sex).
- Your partner’s condom broke or slipped off while you were having sex.
- You were forced to have unprotected intercourse (rape).
How does emergency contraception work?
The medications work by giving a strong short burst of hormones that changes the cycle and prevents ovulation.
It’s important to remember that EC doesn’t continue to protect against pregnancy during the rest of the menstrual cycle. You should not have intercourse or use a barrier method, such as a condom.
Does emergency contraception (EC) cause an abortion?
Emergency contraception (EC) does not work if a woman is already pregnant. EC will NOT cause an abortion.
How is emergency contraception taken?
There are three types of emergency contraception:
- Plan B One-Step™ and Next Choice®. Both products contain only one kind of hormone, a progestin, and it comes as 1 or 2 pills. A woman can take the total dose of 1.5 mg levonorgestrel in Plan B One-Step™ as one pill, or use Next Choice® and take both pills (.75 mg in each tablet) at the same time or take one pill followed by the second pill twelve hours later. Both kinds of EC work best if taken within 3 days (72 hours) of unprotected sex, but can be taken up to 5 days but the earlier it is taken the more effective it is. No prescription is needed.
- ella™ (urlipristal acetate or UPA) is an emergency contraceptive that works by stopping or delaying ovulation. It’s one pill (one dose) that can be taken up to 5 days or 120 hours after unprotected intercourse. A prescription is needed. In many cases, a pregnancy test is also needed.
- Copper Intrauterine Device: This is a small copper device that when placed in your uterus (through your vagina), not only prevents current pregnancy but future pregnancies as long as it remains in your uterus. It is the most effective option, especially in obese women. The Copper Intrauterine Device can be inserted in a woman’s uterus at most family planning clinics and if the woman has no signs of vaginal or uterine infection, it can be inserted right away.
How effective is emergency contraception?
It’s important to remember that emergency contraception doesn’t always work. It doesn’t guarantee that pregnancy will be prevented. Oral hormones used for emergency contraception lowers your risk of pregnancy by 89%. The risk of getting pregnant depends on when in your menstrual cycle you had sex and what kind of birth control you use. You’re more likely to get pregnant around the time when the ovary releases an egg (ovulation).
Is emergency contraception (EC) safe?
Yes. Millions of women have used emergency contraception (EC) without any problems.
Does emergency contraception (EC) cause birth defects?
Emergency contraception does not cause birth defects or affect the health of future children that a woman may have.
Does emergency contraception (EC) have any side effects?
EC is tolerated well and side effects are usually absent or mild. A few percent of women may have nausea, dizziness; headache and/or stomach pain, temporary irregular menstrual periods, and breast tenderness with Plan B One Step™, Next Choice® or ella™. Some women may complain of moderate nausea and vomiting if regular birth control pills are used (for EC). Side effects from emergency contraception (when using regular birth control pills) most often go away after 1-2 days. There are over-the-counter medicines you can get such as (Dramamine II or Bonine) for nausea.
Where can I get emergency contraception?
In the United States any woman can get (progestin-only) EC at pharmacies without a prescription. You may need to check many different pharmacies, because EC is not available in all pharmacies.
Use the EC website to find a health care provider or pharmacy if you have any questions about emergency contraception.
Be ready to answer the following questions:
- When was the first day of your last menstrual period?
- When was the exact date and time of unprotected sex?
- What types of birth control have you have used in the past?
Can I use emergency contraception as my regular form of birth control?
Emergency contraception is not meant to be a regular method of birth control. It’s meant to be a one-time emergency treatment. Emergency contraception can be used when a condom breaks, when a diaphragm or cervical cap gets moved, if a woman is raped, or any time when there is unprotected sex. You should not use emergency contraception as your only protection against pregnancy, because this method doesn’t work as well as other types of birth control. Also, emergency contraception does not protect against sexually transmitted infections.
When can I expect my next menstrual period after I have taken emergency contraception?
Your period should start within 2-4 weeks after taking EC. Your next period may start a little early or a few days later than usual. You may also have spotting, however; this is neither common nor serious. If your next period is late, contact your health care provider and get a pregnancy test.
What if I have problems after I have taken emergency contraception (EC)?
If you have any problems after you take emergency contraception, you can contact your health care provider.
You should definitely call your health care provider if:
- You do not get your period within 2 weeks after taking EC
- You have very bad abdominal (belly) pain
- You are spotting (small amount of blood on your underwear in between your menstrual periods)
- Your next menstrual period is very light
- You are dizzy
Do I need to do anything else to prevent pregnancy after I have taken emergency contraception?
Yes. You should talk to your health care provider about using a regular type of birth control method. Until you have your next menstrual period, it is best not to have sexual intercourse. If you decide to have intercourse, make sure to use a barrier method, such as a condom, every time you have sex even if you are taking birth control pills. Your health care provider may suggest that you start birth control pills right away after emergency contraception. Find out more about birth control methods so you can start thinking about what method will be best for you.
