Ecinq 30mg Emergency Pill is an effective morning after pill intended to prevent pregnancy after unprotected sex or contraceptive failure. It contains 30mg of ulipristal acetate and can be effective for up to 5 days (120 hours) after unprotected sex, though it is more effective the sooner it is taken. It works by preventing or delaying ovulation and is intended for emergency use only, not as a replacement for regular contraception. It is suitable for women of childbearing age and can be taken at any time during the menstrual cycle.
