The main and only aid of contraception is to help prevent pregnancy in a woman. If a woman has sexual intercourse with a male, and the sperm of the male comes in contact with her ova (egg), there is every possibility for such a woman to get pregnant. This is where contraception comes into play, by preventing the sperm from coming in contact with the eggs. There are so many contraceptive pills out in the market, like Plan B, Back Up, Postpill and postinor 2 is one of them and so much more. Read on as we look at the disadvantages of postinor 2.

Postinor 2 is a common and a very popular emergency contraceptive medicine that is usually used to prevent pregnancy by delaying a woman from releasing eggs or by preventing the sperm from coming in contact with any realised eggs by thickening the cervical mucus. The active ingredient in postinor 2 is levonorgestrel. 

Postinor 2 work effectively at 95% to prevent unwanted pregnancy if used immediately or within 72 hours after unprotected sexual intercourse. From estimation, postinor 2 85% sure and has the ability to prevent unexpected pregnancy.

Some people ask if they have to wait 72 hours after unprotected sex before they can take postinor 2. The sooner you take the postinor 2 after unprotected sex, the better for you. Though some people call it day after pill or morning after pill, but that does not mean that you have to wait till morning before you can take it. The earlier you take the pill after intercourse, the higher your chance of not getting pregnant. So you can take your Postinor immediately or within 72 hours of unprotected sex.

Commonly Asked Questions About Postinor 2


Question 1: During Ovulation, Does Postinor 2 Work?

Answer: Postinor 2 is known to work effectively in preventing pregnancy. Postinor 2 works in two different ways. If it is taken before ovulation, it will delay the woman from releasing egg, or if it is taken after ovulation, it will prevent the sperm from coming in contact with the eggs. 

Postinor 2 should not be taken if pregnant. It won’t work on an already pregnant woman, and it can’t hurt the growing fetus. Also, it should not be taken by someone who is allergic to levonorgestrel or other ingredients in postinor. And lastly, it is not a drug for HIV/Aids and cannot cure sexually transmitted diseases.

Question 2: How Often Should Postinor 2 Be Taken?

Answer: There are other methods that can be used to prevent pregnancy. The use of postinor should not be a regular thing. It should only be used in an emergency situation and not a regular method of contraception. Postinor 2 has less side effects or health risks than using an abortion pill or going through an abortion in a hospital. 

Postinor 2 should only be taken more than once in a menstrual cycle (i.e. not more than once in a month). If it is taken more than once, it will disturb your period (menstrual cycle). See your doctor or family planning clinic for the best and most suitable contraceptive method that will work for you, because it will work best at preventing you from getting pregnant until you are ready to get pregnant.


Question 3: How Many Postinor Do I Take At Once?

Answer: There are two types of postinor, the single dose and the double dose. The single dose postinor contains just one pill in the pack. You are supposed to take the single-dose pill within 72 hours after having an unprotected sex. While the double dose postinor contains two pills in the pack. After taking pill one, twelve hours later, you can take the second pill. The earlier you take the pill after unprotected sex, the better it works effectively.

The efficiency and effectiveness of this pill depend on how many hours is gone since you had unprotected sex and how early you take it after unprotected intercourse.


Question 4: How Do I Know If The Postinor 2 Worked?

Answer: You will know that the postinor worked only if you see your next period. Then you are sure that it worked.


Question 5: Is There Any Effect Of Postinor 2 On A Baby?

Answer: Postinor 2 is not recommended for a breastfeeding mother to take because of its unpredictable side effects on babies. In a breastfeeding mother, most drugs taken are a little bit transferred to the breast milk. It is difficult to know what the effect of drugs on a baby taken by the mother.

Through research, a trace of postinor has been detected in breast milk, which is why it is not recommended for a breastfeeding woman.


If you are pregnant, then the emergency contraceptive postinor 2 or any other type of contraceptive will not work, and it will not harm your pregnancy or the fetus. If you have taken postinor 2 already after your last period and then later find out that you are pregnant, do not take it or any other contraceptive anymore.
