…..The two most common protocols are the progesterone only pill (Plan B) and the estrogen and progesterone pills. Plan B consists of only one pill, and the second regime of estrogen and progesterone is a two-dose treatment 12 hours apart. Both of these treatments are available over-the-counter for women 17 or older. For women under 17, a prescription is necessary.
…..There is no clear reason for how the emergency contraception works. A few explanations have been promulgated:
- Inhibition or delay of ovulation
- Interference with sperm transport or penetration of the egg
- Thickening of cervical mucous
