What is the Plan B/ One-Step/ Morning After Pill?
Plan B one-step pill is an emergency contraception pill that can be used after having unprotected sex. It is also called the morning-after pill. However, it is best to take the pill immediately after you engage in unprotected sex to increase its effectiveness.
How Effective is the Plan B Pill?
The Plan B pill, when taken within the duration of 72 hours after engaging in unprotected sex, is about 89% effective. When taken within 12 hours after sex, it can lower the chance of pregnancy by about 95%.
How Does the Plan B Pill Work?
Plan B one step is a single tablet emergency contraception that has levonorgestrel, which is a female hormone responsible for prevention ovulation. This hormone can prevent the ovary from release an egg or make it harder for the sperm or the fertilized egg to get to the uterus by causing changes in the lining of the uterus and the cervical mucus.
Levonorgestrel is the same hormone used in birth control pills, but Plan B has a higher dose of it, about 1.5 milligrams.
