Postinor 1 is an emergency contraceptive pill, containing the main active ingredient is Levonorgestrel 1.5mg. It can be used within 72 hours after unprotected intercourse or the used method has not worked. Levonorgestrel can prevent pregnancy through several mechanisms:

In addition, the drug also changes the endometrium and affects implantation. However, Levonorgestrel is not effective once the eggs have implanted. If taken within 72 hours of unprotected intercourse, Postinor 1 can prevent about 84% of expected pregnancies.

3. Can I use postinor 1 birth control while breastfeeding?
Levonorgestrel is excreted in breast milk, however this is not considered harmful to the infant. Actual drug concentrations in milk depend on the dose and route of administration. An observational study of 100 nursing women found that a single oral dose of levonorgestrel did not adversely affect lactation or the health of the infant. Therefore, women who are breastfeeding can still use oral levonorgestrel for emergency contraception. However, if you are not sure, you can take the medicine immediately after breastfeeding and do not breastfeed for at least 8 hours. That way, the time between taking the medicine and the next feeding is long enough to reduce the amount of medicine in your milk and won't harm your baby.
