Emergency contraception, commonly referred to as the “morning-after pill,” is a method designed to prevent pregnancy after unprotected intercourse. This can be crucial in situations such as contraceptive failure, unprotected sex, or sexual assault.
What is Emergency Contraception?
Emergency contraception involves taking a high dose of specific types of birth control pills, which may contain either estrogen and progestin or just progestin. In 2013, the FDA removed age restrictions, allowing individuals to purchase these pills over the counter without a prescription.
How Does It Work?
Emergency contraception operates through synthetic hormones that regulate ovulation and fertility, mimicking the body’s natural hormonal processes. It can prevent pregnancy by:
- Inhibiting Ovulation: It may stop or delay the release of an egg from the ovaries.
- Thickening Cervical Mucus: This makes it more difficult for sperm to reach and fertilize the egg.
- Altering the Uterine Lining: It can change the endometrial lining, reducing the likelihood of a fertilized egg implanting.
How to Use Emergency Contraception?
The first dose should be taken as soon as possible, ideally within 72 hours after unprotected sex, followed by another dose 12 hours later. Some formulations only require a single dose, also to be taken within the 72-hour window.
Effectiveness
When taken promptly, emergency contraception can reduce the chance of pregnancy by 75-89%, depending on the specific medication used. However, it’s not as effective as regular contraceptive methods and should not be seen as a primary form of birth control.
Side Effects and Health Risks
Common side effects include headaches, dizziness, nausea, vomiting, irregular periods, breast tenderness, and abdominal pain. It’s important to note that emergency contraception may alter your next menstrual cycle, either causing it to come early or late, or resulting in changes in flow. This method is not recommended for those who are already pregnant. If symptoms of pregnancy occur, a test is advisable. While research is limited, current studies have not shown any adverse effects on a fetus if the method fails.
Cost
Emergency contraception is available over the counter, with prices typically ranging from $30 to $60 or more.
Does Emergency Contraception Protect Against STIs?
Emergency contraception does not provide any protection against sexually transmitted infections (STIs). For those concerned about STIs, it’s essential to consider additional protective measures.
