Who Can Use Emergency Contraception?

Any girl who has reached the reproductive age and has engaged in unprotected sex can use emergency contraception. There is no age limit on the use of any form of emergency contraception unless there is an underlying medical condition that requires special attention.

Methods of Emergency Contraception

There are primarily two methods of emergency contraception.

  1. ParaGard IUD Or Copper IUD: This is an intrauterine device that is inserted into your uterus. This can be used up to 5 days after having unprotected sex. The IUD is also a long-term contraceptive option that can work for about 10 to 12 years.
  2. Contraceptive Pills: These emergency pills are of two kinds:

ParaGard IUD Or Copper IUD

  • Pills with ulipristal acetate: There is currently only one brand called Ella that offers these pills. Such pills also need a doctor’s prescription and should be used within 5 days or 120 hours after unprotected sex. The effectiveness of these pills remains the same even on the 5th
  • Pills with levonorgestrel: These pills are best taken immediately after having unprotected sex. Their effectiveness depends on how soon they are consumed. However, for they should be taken at least within 72 hours or 3 days of unprotected sex. Plan B One-Step, Take Action, After Pill, I-pill, etc, are some of the brands with contraceptive pills containing levonorgestrel.

How Does Emergency Contraception Work?

Emergency contraception pills usually work by delaying ovulation. This essentially means that they are preventing fertilization by blocking the eggs from being released by the ovary. Levonorgestrel pills delay ovulation but in cases where the implantation of the egg and fertilization have already taken place, it does not stop the pregnancy.

Pills with ulipristal acetate delay ovulation but may also prevent the fertilized egg from being implanted in the uterus, thus avoiding pregnancy. Hence, these work for up to 5 days to prevent pregnancy, the period of time that the egg takes to get fertilized and implant.

The copper IUD makes it harder for sperms to swim through and reach the egg, hence it preventing pregnancy

In Which Situations Should You Use Emergency Contraception?

Emergency contraception is ideal if you do not want to end up with an unwanted pregnancy for any of the following reasons.

  • Your partner’s condom broke or was defective.
  • Your partner did not pull out in time(The pull-out method is not effective)
  • You missed out on taking birth control pill or other using contraceptive methods like patches or rings. Also, if you had applied the patch on a wrong day.
  • You miscalculated your safe period
  • You engaged in unprotected sex without any birth control method
  • If the diaphragm or the cervical cap slips out of its place or if you have removed it too early.
  • If your IUD or hormonal contraceptive slips out of place.

What Kind of Emergency Contraception Is Best for You?

The kind of emergency contraception that is best for you depends on a few factors like

  • The day on which you had unprotected sex
  • Your BMI or height and weight
  • Your history of pill or oral contraceptive usage
  • Your breastfeeding status
  • Access to the ECP
  • Any medications you are on
  • Your pregnancy status

While it is best to use the most effective methods of emergency contraception methods, IUDs and Ella are not available easily. IUD has to be inserted by a doctor or nurse and Ella is a prescription drug and cannot be purchased over the counter.

Plan B or other levonorgestrel pills are over the counter pills that do not require a prescription. While they can be about 88% to 95% effective when taken within 72 hours of unprotected sex, they are not as effective as Ella or IUD.

However, it is important to remember that if you were on birth control pills, ring, patch or the birth control shot, Ella will not be as effective. In such cases, levonorgestrel pills work better. Also, do not take pills like Plan B and Ella together as they can cancel out the effect.

The key to getting the best result from emergency contraception is to use it at the earliest interval.

How Should I Take an Emergency Contraceptive Pill?

Emergency contraceptive pills are taken orally immediately after unprotected sex. Levonorgestrel pills should be taken within 72 hours of unprotected sex and ulipristal acetate pills like Ella can be taken within 120 hours after unprotected sex. In case you vomit within two to three hours after taking the pill, you can consult your doctor about taking another dosage.

Effectiveness of Emergency Contraception

Plan B, when taken within 72 hours after unprotected sex, can prevent 85% of the unwanted pregnancies. However, these pills become less effective in overweight women and do not work efficiently in women over 165 pounds or 75 kg.

Ella’s effectiveness in preventing pregnancies can last for up to 120 hours and works just as well on the 5th day as it works on the first. Also, emergency contraceptive pills will not prevent pregnancy if you have unprotected sex after you take them. You will have to take another dose to avoid pregnancy.
