What Postinor 2 is and what is used for

Postinor 2 tablet contains a synthetic luteal hormone-like active substance,levonorgestrel.
Postinor 2 tablet prevents about 85% of expected pregnancies when the first tablet is taken within 72 hour's (3days) of unprotected sex. Postinor 2 tablet Will not prevent pregnancy in every instance, but the tablet are more effective the sooner after unprotected sex they are taken(it is better to take the first tablet within one day rather then delay until the third day). You need to take the second tablet 12 hours (but no more than 16 hours) after the first.
Postinor 2 tablet is thought to work (1) by stopping your ovaries  from releasing an egg.(2) by preventing sperm from fertilising an egg you may have already released.

How to take Postinor 2

Always take Postinor 2 exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Take one tablet as soon as possible but no later than 72 hours after you have had unprotected sex. Do not chew but swallow the tablet whole, with water if necessary. Do not delay taking the first tablet. The tablets work better the sooner you take them after having unprotected sex.

It is important to take the second tablet 12 hours and no longer than 16 hours after the first tablet. This may mean that you need to set your alarm clock for taking the second tablet during the night. If you are unsure about the timing of the tablets, ask your pharmacist to advise you.

How often can you use Postinor 2?

You should only use Postinor 2 tablet in emergencies and not as a regular method  of contraception. If Postinor 2 tablet is used more than once in a menstrual cycle it is more likely to upset your menstrual cycle (period).
Postinor 2 does not work as well as a regular method of contraception. If you think, you need repeated courses of emergency contraception, you should consider long-term methods of contraception.

If you take Postinor 2 than you should

Although there have been no reports of serious harmful effects from taking too many tablets at once, you may feel sick, actually be sick(vomit), or have vaginal bleeding. You should ask your  pharmacist, your doctor or the family planning clinic for advice.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking any medicine.


 You should not take this medicine if you are already pregnant. If you do become pregnant even after taking this medicine, it is important that you see your doctor. there is no evidence that Postinor 2 Will harm a baby that develops in your uterus/womb if you use Postinor 2 as described. Nevertheless, your doctor may want to check that the pregnancy is not ectopic (Where the baby Develops somewhere outside the womb). This is especially important if you develop severe abdominal pain after taking Postinor 2 or if you have previously had an ectopic pregnancy, fallopian tube surgery or pelvic inflammatory disease.


Very small amounts of the active ingredient of this medicine may appear in your breast milk. This is not thought to be harmful to the baby, but if you are worried you can take your tablet immediately after a breast-feeding and avoid nursing at least 8 hours following tablet taking. In this way you are taking your tablet well before the next feed and reducing the amount of active ingredient your baby may take in with the breast milk. 


Postinor 2 increases the possibility of menstruation disturbances which can sometimes lead to earlier or later ovulation date. These changes can result in modified fertility date; however, there are no fertility data in the long term.
