What is Emergency Contraception?
Emergency Contraception is often referred to as the “morning after pill.” It is a high dose of certain types of the birth control pill, made up of estrogen and progestin or progestin only.
In 2013, the FDA lifted the age limit on emergency contraception, which can now be obtained over-the-counter without a prescription. This form of birth control is sometimes used in the event of unprotected sexual intercourse, in cases of sexual assault and rape, or if another type of birth control has failed.
How Does Emergency Contraception Work?
Emergency contraception works through high doses of the synthetic hormones of estrogen and progestin, or progestin only, which help regulate ovulation and fertility similar to the way in which the natural forms of these hormones work.
Emergency contraception may prevent pregnancy through one or more of these three methods:
- First, it prevents or reduces the probability of an egg being released from the ovaries.
- Second, it thickens the cervical mucus, decreasing the chance of the sperm reaching and fertilizing the egg.
- Third, it changes the lining of the uterus, decreasing the probability of implantation. Click here to learn more about the ethical implications of this third method.
How Do You Use Emergency Contraception?
The first dose of pills is taken as soon as possible (within 72 hours), followed by another dose 12 hours later.
