Expert In Clinical Pharmacology And Drug SafetyView moreEmergency Contraception or also referred as EC in colloquial language are methods adopted to prevent unwanted pregnancy in women after unprotected copulation. This can be considered as the second step to prevent pregnancy when your partner has failed to use condoms.
It is for this reason it named “Emergency” Contraception referring to the immediate steps for unwanted prevention of pregnancy. It is a major constituent of women’s reproductive health. It comes in form of pills taken after copulation to prevent fertilization.
The basic knowledge of EC helps take rational choices in the moment of madness, keeping health as topmost priority.
Why Use Emergency Contraception?
The reason why women use emergency contraception in the simplest form is they don’t want to get pregnant. Pregnancy would have been prevented if the couple would have used contraceptives such as condoms.
The Importance of Timing:
| Time After Unprotected Sex | Effectiveness Trend | Recommendation |
|---|---|---|
| First 24 Hours | Highest | Best time to take emergency contraception |
| 24–48 Hours | Very effective | Still strong pregnancy prevention |
| 48–72 Hours | Moderate | Should not delay further |
| 72–120 Hours | Lower but useful | Some methods still work |
| Beyond 5 Days | Limited options | Medical consultation may be needed |
So, emergency contraception come into play, when due to any reason condoms were not used during intercourse. Now, semen has entered the women’s vagina, emergency contraception pills prevent pregnancy by delaying or preventing ovulation eventually preventing fertilization. This is different from abortion, where fetus is partially or fully formed, and it is surgically removed.
Some Circumstances Where EC Comes Into Use:
- Unprotected Copulation: Failure of using birth control methods like condoms during copulation.
- Contraceptive Failure: Here, a situation might occur where condom might have broken or slipped, skipped birth control medications, or missed dose of any contraceptive injections.
- Sexual Assault: When copulation was forced, such as in rape involving sexual harassment where contraceptive usage is unknown.
When first line of contraceptive methods is skipped knowledge of EC gives a second chance to prevent unwanted pregnancy and eases psychological stress.
When To Use Emergency Contraception
Here time is the key factor. Taking the contraception pill as soon as after copulation increases chances of successful prevention of pregnancy. Also termed as “morning pills,” they are effective for few days after copulation, but it’s better to minimize the time delay.
- The Golden Window: The highest efficiency to prevent pregnancy for these pills is within 24 to 72 hours after copulation.
- 5 Day Limit: Certain ECs such as copper IUD and Ulipristal Acetate tablets remain effective for up to 5 days after copulation.
EC pills work by preventing ovulation. So, if ovulation period is already over then EC medications tend to be less effective. For the same reason, it is advised to immediate consume EC pills.
How To Use Emergency Contraception: The Methods
There are 2 distinct categories of Emergency Contraception, Oral Medications, and Intrauterine Devices (IUDs).
➥ Oral Medications/Levonorgestrel Pills
This is the most common method of EC, the “morning pills” that you must have heard are examples of oral medication. These medications contain high concentration of progestin levonorgestrel.
- Availability: These medications do not require prescription or any age-related criteria while purchase.
- Mechanism: These drugs prevent process of ovulation or release of eggs from ovaries.
- Note on Weight: Some medical reports claim levonorgestrel is less effective in overweight individuals, especially over 75 kg.
➥ Ulipristal Acetate
Unlike Levonorgestrel Pills, these needs prescription for purchase and consumption.
- Advantage: These are highly effective even on 4th and 5th days after copulation. Even after ovulation phase has passed, these pills prevent fertilization.
- Mechanism: These are prescribed when morning pills are no longer effective. It delays ovulation even after eggs have started to release from ovaries, suppressing the female hormone progesterone.
➥ The Copper IUD (ParaGard)
This is the most potent method of emergency contraception.
- Efficacy: Compared to previous 2 methods, it shows the highest level of efficacy once inserted within 4 to 5 days of unprotected copulation.
- Bonus: Once placed by the doctor, it not only prevents current pregnancy but also acts as contraceptive for upcoming 5 to 6 years.
- Mechanism: Copper destroys sperm once it comes into contact, thus preventing fertilization and formation of zygote.
Managing Side Effects and Follow-Up
EC medicines are majorly on the safer side, but mild side effects are a possibility, such as nausea, fatigue, abdominal pain, chest pain, headache etc. These do not need medical assistance; they disappear in first few days on medication.
- Irregular Menstrual cycle: One of the major after effects is irregular menstrual cycle. One can experience very early or delay in periods, and blood flow can be less or intense than normal.
- Excessive Vomiting: In case you vomit after consuming, it indicates the drug has not been assimilated in the body. Reach out to the doctor in such cases.
- Not for any Sexual Disorder: Also note, that EC medications only prevent pregnancy, they do not prevent or treat sexual diseases. If copulation involves spreading of infection, reach out to the doctor for overall treatment.
The Path Forward: Long-Term Contraception
While we discussed about effectiveness of various types of Emergency Contraception, we must understand this is second level of contraception. The ideal method is use to a condom and always promote protected sexual intercourse.
After having successful dose of EC medication, consult the doctor for normalization of usual contraceptive methods.
