Myths about ECP

ECP is not effective if several acts of intercourse have occurred in a row, at the same time?
NO. ECP is equally effective after one or several acts of intercourse in a row provided that all the acts have taken place within 72 hours preceding the intake of the drug.

ECP will act as an efficient contraceptive method until the next menstrual period?
NO. So it is strongly recommended to use a barrier method at each intercourse until the next period and start using a regular suitable contraceptive method from then onwards.
