Emergency contraception to prevent pregnancy after unprotected sex, contraceptive failure (e.g., broken condom), or missed regular birth control doses. It is not intended for use as a regular contraceptive method.
Take Action contains levonorgestrel 1.5mg, which works primarily by preventing or delaying ovulation. It may also thin the uterine lining and thicken cervical mucus to help prevent fertilization. It does not terminate an existing pregnancy.
Most effective when taken within 72 hours of unprotected sex; effectiveness decreases over time. Does not protect against sexually transmitted infections. May cause side effects such as nausea, abdominal pain, fatigue, headache, or changes in menstrual bleeding. Should not be used if pregnancy is already confirmed. Emergency contraception is for emergency use only and is not a substitute for routine contraception.
