What Is The Morning-After Pill?

Emergency contraception refers to birth control methods that is used to prevent pregnancy after having sex without protection. While emergency contraception can be taken within 72 to 120 hours after having unprotected sex, it is reccomdnede that you take them as soon as you can This will increase their effectiveness at avoiding unwanted pregnancies from occurring. 

Emergency contraception prevents pregnancy from occurring either by delaying ovulation to prevent fertilization from happening or killing the sperm before it reaches the egg. It is important to know that emergency contraception does not induce an abortion. 

Emergency contraceptive pills (ECPs), also commonly known as "morning-after" pills, are hormone pills. They contain much higher levels of hormones found in birth control pills to prevent pregnancies. 

There are currently 2 main types of morning-after pills on the market, either containing the hormone levonorgestrel, or containing the hormone ulipristal acetate. 

Levonorgestrel Morning-After Pills 

Levonorgestrel morning-after pills (Plan B, Postinor) prevent unwanted pregnancies from happening by delaying ovulation and stopping the fertilization of the egg. Levonorgestrel morning-after pills are at its most effective when you taken them within 72 hours after having unprotected sex.

Morning-After Pills In Singapore FAQ

1. How Soon Must You Take The Morning-After Pill To Avoid Pregnancy? 

While exact timings will differ between which morning-after pill you have chosen, they should be taken within 72 hours (3 days) after having unprotected sex. 

As mentioned earlier, morning-after pills that contain the hormone ulipristal acetate are considered one of the best as they provide a much wider time frame (120 hours, 5 days) while also having a high success rate of 98.8%. 

Of course it is still highly recommended that you take the morning-after pill as soon as you after having unprotected sex. The faster you're able to take the morning-after pill, the more effective it will be. 

2. How Often Can I Use The Morning-After Pill? 

There is no limit to how many times you can take the morning-after pill as multiple usage will not affect the emergency contraceptive's ability to successfully prevent unwanted pregnancies. 

However, it is not recommended that you rely on morning-after pills as your main method of birth control. This is because morning-after pills do not prevent unwanted pregnancies as well as other forms of birth control like birth control pills, rings and patches. Morning-after pills are also significantly more expensive and less convenient to take than other birth control methods.

As mentioned earlier, taking morning-after pills can cause you to experience irregular periods, which makes it more difficult to predict your next cycle. So while it is completely safe to take morning-after pills as often as you need to, using regular forms of birth control (birth control pills, rings patches, IUDs etc) are still the best ways to prevent unwanted pregnancies long-term.

3. Will Taking Morning-After Pills Often Affect My Fertility And My Chances Of Getting Pregnant In The Future? 


Taking the morning-after pills will not prevent you from getting pregnant in the future or cause you any fertility issues.

You should take morning-after pills when you deem them to be necessary after having unprotected sex.
