Emergency Contraceptive Pill

The Emergency Contraceptive Pill is also known as ECP, the Morning After Pill or Plan B.  ECP is used after sex to prevent pregnancy.

  • It can be taken up to 5 days after having sex.
  • The sooner it is taken, the better it works.

ECP can prevent an unplanned pregnancy when:

  • No birth control was used
  • Birth control pills, patch or ring were not used as intended (for ex., you missed taking your pill for three days)
  • The condom slipped, broke or leaked
  • The diaphragm or cervical cap dislodged during sexual intercourse or was removed too early
  • There is a calculation error for the fertile period
  • A sexual assault occurred; non-consensual sex

Health Canada issued an advisory stating the Emergency Contraceptive Pill:

  • May be less effective in women weighing 75 to 80 kg (165 to 176 pounds)
  • Is not effective in women weighing more than 80 kg (176 pounds)
