There are several options available for emergency contraception, also known as the “morning-after pill,” which can be used to prevent pregnancy after unprotected intercourse or contraceptive failure. Here are the different types of emergency contraception and how they work:
Levonorgestrel pill: This is the most commonly used emergency contraceptive pill. It contains levonorgestrel, a synthetic hormone that is also used in some regular birth control pills. It is available over-the-counter without a prescription in many countries. It is most effective when taken within 72 hours (3 days) after unprotected sex, but can still be used up to 120 hours (5 days) afterward, although effectiveness decreases over time. Levonorgestrel works by preventing or delaying ovulation and may also interfere with fertilization and implantation.
Ulipristal acetate pill: This is a prescription-only emergency contraceptive pill. It contains ulipristal acetate, a selective progesterone receptor modulator. It is effective up to 120 hours (5 days) after unprotected sex. Ulipristal acetate works by delaying ovulation and may also affect the lining of the uterus, making it less receptive to implantation.
Copper Intrauterine Device (IUD): The copper IUD is a non-hormonal contraceptive method that can also be used as emergency contraception. It is the most effective form of emergency contraception and can be inserted up to 5 days after unprotected sex or up to 5 days after the expected ovulation date. The copper IUD works by preventing fertilization by immobilizing sperm and by altering the lining of the uterus to prevent implantation of a fertilized egg.
It’s important to note that emergency contraception is not intended to be used as a regular form of contraception and does not protect against sexually transmitted infections (STIs). Additionally, it may not be 100% effective in preventing pregnancy, especially if used incorrectly or after the recommended timeframe. Therefore, it’s advisable to use regular, ongoing contraception for effective pregnancy prevention and to practice safe sex to protect against STIs.
If you are in need of emergency contraception, it’s recommended to consult a healthcare professional or visit a healthcare provider as soon as possible to discuss the options available and determine the most suitable choice for your situation.
