In today’s world, where information is power, understanding the mechanics and implications of contraceptive choices is paramount. Among these choices, the use of emergency contraceptive pills (ECPs) stands out as a crucial aspect of sexual & reproductive health.
This blog aims to demystify the ECP, explaining what it is, exploring its types, and the science behind it.
What Is An Emergency Contraceptive Pill?
An emergency contraceptive pill (ECP) is a form of contraception or birth control, intended to prevent and unintended pregnancy. It is used after unprotected sex or contraceptive failure has occurred, for example, when contraception was not used, or the condom broke or slipped during sex. It is also known as the morning-after pill or plan B.
An ECP is most effective when taken as soon as possible within 72 hours after unprotected sex,. It is not meant for regular use, but only as a backup option for contraceptive emergencies, and it doesn't work if a pregnancy has already begun.
How Does An Emergency Contraceptive Pill Work?
An ECP works primarily by delaying or inhibiting ovulation (the phase of the female menstrual cycle when an egg (ovum) is released from one of the ovaries). This, in turn, prevents the male sperm from fertilizing the female egg to result in a pregnancy. The ECP does not work if a pregnancy has already occurred, and it does not induce an abortion.
Pills Used For Emergency Contraception
1. Levonorgestrel (LNG) containing pill
Levonorgestrel (LNG) is a synthetic progesterone (a female hormone). This single pill contains 1.5 mg of LNG and works primarily by preventing or postponing ovulation. It can help prevent an unintended pregnancy if taken as soon as possible up to 72 hours (3 days) after unprotected sex. It is an over-the-counter pill and can be purchased from a pharmacy without a doctor's prescription.
2. Ulipristal Acetate (UPA) containing pill
Another pill that can be used as emergency contraception is the pill containing Ulipristal acetate (UPA). It works by preventing the female hormone progesterone from having its normal effect, in order to prevent or delay ovulation, and to thin the lining of the uterus to prevent implantation (when a fertilized egg attaches itself to the wall of the uterus to begin a pregnancy).
A UPA-containing pill can help prevent an unintended pregnancy if taken as soon as possible up to 120 hours (5 days) after unprotected sex. However, this pill can only be purchased and used with a doctor's prescription and guidance, as it is not yet approved for use as an emergency contraceptive in India.
Conclusion
Understanding the intricacies of an emergency contraceptive pill (ECP) is vital in making informed decisions regarding one's sexual & reproductive health. By exploring how it works, it's types, and the science behind it, individuals can better navigate their options following unprotected sex or contraceptive failure.
