Plan b

From WikiMD's Food, Medicine & Wellness Encyclopedia

Plan B is an emergency contraceptive that is used to prevent pregnancy after unprotected sexual intercourse or contraceptive failure (such as a condom breaking). It is also known as the "morning-after pill."

Overview[edit | edit source]

Plan B contains the hormone levonorgestrel, which can prevent ovulation, interfere with fertilization, or prevent a fertilized egg from implanting in the uterus. It is most effective when taken as soon as possible after unprotected sex, but can be taken up to 72 hours afterwards. However, it should not be used as a regular form of contraception.

Effectiveness[edit | edit source]

The effectiveness of Plan B depends on how soon after sex it is taken. If taken within 24 hours, it is about 95% effective. If taken between 48 and 72 hours after sex, it is about 61% effective. It is not effective if a woman is already pregnant.

Side Effects[edit | edit source]

Common side effects of Plan B include nausea, abdominal pain, fatigue, headache, and menstrual changes. In rare cases, it can cause an allergic reaction.

Availability[edit | edit source]

In many countries, including the United States, Plan B is available over-the-counter without a prescription. However, in some places, it is only available with a prescription or not available at all.

Controversy[edit | edit source]

Plan B has been the subject of controversy, particularly in relation to issues of sexual ethics, reproductive rights, and pharmacy ethics. Some people believe that it is a form of abortion, while others argue that it is a necessary part of reproductive healthcare.
