The drug is taken orally - two pieces during the first 72 hours after unprotected intimacy. It is important to adhere to the following principle: the first - as soon as possible, and 2 - twelve (no later than 16) hours after drinking the first.
"Postinor" can be used as a method of emergency contraception, regardless of the day of the menstrual cycle. If a woman has an irregular cycle, it is recommended to exclude the fact of pregnancy before using the drug. This tool is not allowed to be taken under the age of 16, with severe liver failure, as well as hypersensitivity to certain components.
