Hi.No formal study of the effect of food on the absorption of levonorgestrel
has been undertaken so far.Postinor-2 is not intended as a regular method of contraception
. It is used to prevent pregnancy
when taken within 72 hours of unprotected intercourse
. It is estimated that Postinor-2 will prevent 85% of expected pregnancies. 95% of expected pregnancies will be prevented if taken within the first 24 hours, declining to 58% if
taken between 48 hours and 72 hours after unprotected intercourse.Hope this helps.Take care.
