Emergency Contraception
Emergency contraception, also known as the "morning-after pill," is a form of birth control used to prevent pregnancy after unprotected sexual intercourse. It is a safe and effective option when used correctly within a specific timeframe following unprotected sex, contraceptive failure or sexual assault.
Oral emergency contraception works by suppressing ovulation. It will not work if you have already ovulated. Emergency contraception is only useful for the prevention of pregnancy—it will not affect an existing pregnancy. Emergency contraception is not the same as abortion pills.
Emergency contraception is not intended for routine use as a method of birth control, as there are more effective and affordable long-term options.
Emergency Contraception and Weight
Current medical literature has found that the effectiveness of emergency contraception pills can be impacted by body weight. The most effective option for people of all weights is to have an IUD inserted within 5 days of unprotected sex. For those who may not want an IUD, the most effective emergency contraception option for people of all weights is ella™.
If you weigh over 165 pounds, emergency contraception pills such as Plan B will be less effective, and ella™ will be more effective. If you weigh over 195 pounds, ella™ will not be as effective. It is recommended to consult a healthcare provider for help on deciding what type of emergency contraception to take.
