How Does Emergency Contraceptive Work?

Depending upon where you are in your cycle, Emergency Contraceptive may work in one of these ways:

  • It may prevent or delay ovulation.
  • It may interfere with fertilization of an egg.

It is also possible that this type of emergency birth control prevents implantation of a fertilized egg in the uterus by altering its lining.

 

  • Emergency Contraceptive is not the same as RU-486, which is an abortion pill. 
  • It does not cause a miscarriage or abortion.


In other words, it does not stop development of a
fetus once the fertilized egg implants in the uterus. So it will not work if you are already pregnant when you take it.

How Effective Is One-Dose Emergency Contraceptive?

If you take it within 72 hours after you’ve had unprotected sex, One-Dose Emergency Contraceptive can reduce the risk of pregnancy by up to 89%. If taken within 24 hours, it is about 95% effective.

But you should know that Emergency Contraceptive is not as effective as regular contraception. So don’t take it as your main form of birth control. And, it does not protect you against sexually transmitted diseases. Think of it as a backup — not for routine use. 

How to Take Emergency Contraceptive

Emergency Contraceptive can be purchased over the counter at drugstores without a prescription or proof of age.  

You can take Emergency Contraceptive if:

  • You didn’t use any birth control.
  • The condom came off or broke.
  • The diaphragm slipped out of place.
  • You missed at least two or three active birth control pills in a row.
  • You forgot to insert your ring or apply your patch.
  • Your partner didn’t pull out in time.
  • You have another reason to think your birth control might not have worked.
  • You were forced to have sex.

Remember: Emergency Contraceptive will not protect you from getting pregnant if you have sex after taking the pills. Instead, you need to take it right after you have unprotected sex. Using condoms at all times is best. 

Do not take Emergency Contraceptive if:

  • You know you are pregnant or suspect you might be.
  • You have a history of allergy or hypersensitivity to its ingredients.
  • You have a history of recent abnormal vaginal bleeding that your doctor has not yet evaluated.
  • You weigh over 165 pounds.

Side Effects of Emergency Contraceptive

Many women have taken emergency contraception without serious complications. But it’s a good idea to ask your doctor about possible interactions with other medications.

Emergency Contraceptive is considered safe for most women. You should not take it if you are pregnant because it will not end the pregnancy.

Potential side effects of Emergency Contraceptive include:

nausea, abdominal pain, fatigue, headache, menstrual changes, dizziness, breast tenderness, vomiting

If you vomit within two hours after taking the drug, call a healthcare professional to find out if you should repeat the dose.

With Emergency Contraception, you may also have some unexpected bleeding. It should go away by the time of your next period. However, it is possible that it may cause your next period to be heavier or lighter than usual. It may also come earlier or later than is normal for you. If you don’t get your period within three weeks, get a pregnancy test to make sure you’re not pregnant.
