This article discusses modern emergency contraceptive methods used to prevent pregnancy after unprotected sexual intercourse. Emergency contraception methods are artificial methods used in cases of emergency, such as unprotected sexual intercourse or contraceptive failure. They should not be used as everyday contraceptive methods.
Two emergency contraceptive methods are currently available in Sri Lanka:
- Emergency contraceptive pills Emergency contraceptive pills, sold under the brand name “Postinor” in Sri Lanka, are an effective method for preventing pregnancy after unprotected sexual intercourse. These pills contain a medicine called Levenogestrel and can be taken as two pills or one pill. A pill contains ten times more Levenogestrel than a regular birth control pill.
Emergency contraceptive pills containing Levonorgestrel can be taken within 96 hours after unprotected sexual intercourse to prevent pregnancy. Taking them as soon as possible after unprotected sexual intercourse can increase their effectiveness. This medicine prevents ova (eggs) from releasing from the ovary and weakens the passage of sperm through the cervix, creating an unsuitable environment for the implantation of an embryo in the uterus. However, it is only effective if taken before ovulation. Therefore, pregnancy cannot be prevented by taking these pills during the last 14 days of the menstrual cycle.
The effectiveness of emergency contraceptive pills containing Levonorgestrel ranges from 52% to 94%. It is important to emphasise that emergency contraception should be used as soon as possible after unprotected sexual intercourse to increase its effectiveness. In addition, it is important to note that emergency contraceptive pills should not be used frequently as they contain high amounts of hormones, which can cause complications.
Complications such as vomiting, nausea, and irregular menstruation may occur due to emergency contraceptive pills. If vomiting occurs within two hours of taking the medicine, the same dose should be taken again. If the period is late for more than seven days from the scheduled date, a urine test must be done to check for pregnancy. Emergency contraceptive pills containing Levonorgestrel are not effective after the embryo has implanted because they do not cause an abortion.
- Intrauterine loop (Intrauterine Device IUD) An IUD is a small device that is inserted into the uterus through the cervix by a doctor. It prevents the implantation of an embryo in the uterus. An IUD can be inserted within five days of unprotected sexual intercourse to prevent unwanted pregnancy. This is a more reliable method of emergency contraception than hormonal pills, with an effectiveness rate of 99%. Moreover, the same IUD can be used as a birth control method for up to 10 years, making it a convenient option.
It is important to note that emergency contraception is not a substitute for regular contraceptive methods. Regular contraceptive methods, such as condoms, birth control pills, and IUDs, are more reliable and safer than emergency contraception. However, emergency contraception can be a useful backup option in case of contraceptive failure or unprotected sexual intercourse.
Knowing how to access emergency contraception in Sri Lanka is also important. Emergency contraceptive pills are available in most pharmacies, and a doctor can insert IUDs. It is recommended to consult a doctor or healthcare provider to choose the most suitable emergency contraceptive method for you.
Lastly, several myths and misconceptions about emergency contraception should be addressed. Emergency contraception does not cause abortions or infertility, and it is safe and effective when used correctly. However, it should not be used frequently as it can cause complications.
In conclusion, emergency contraception is an important option for preventing unwanted pregnancies after unprotected sexual intercourse or contraceptive failure. Emergency contraceptive pills and IUDs are the two emergency contraceptive methods available in Sri Lanka. Emergency contraception should
