According to guidelines from ACOG, data are not available on the safety of current regimens of emergency contraception if used frequently over a long period. However, oral emergency contraception may be used more than once, even within the same menstrual cycle. Treatment with emergency contraception should be initiated as soon as possible after sexual intercourse to maximize efficacy. Emergency contraception should be made available to patients who request it as long as 5 days after sexual intercourse.
The ACOG guidelines also indicate that existing data suggest that use of levonorgestrel emergency contraception does not increase the chance that a subsequent pregnancy will be ectopic.
The ACOG guidelines state that no clinical examination or pregnancy testing is necessary before provision or prescription of emergency contraception. Emergency contraception should be offered or made available any time unprotected or inadequately protected sexual intercourse occurs and the patient is concerned that she is at risk for an unwanted pregnancy. Emergency contraception should not be withheld or delayed in order to test for pregnancy, nor should it be denied because the unprotected coital act may not have occurred on a fertile day of the menstrual cycle.
