Are emergency contraceptive pills harmful to health?

More Info


Emergency contraceptives (EC), commonly known as "morning-after pills," are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. The two most common types of emergency contraceptives are levonorgestrel (Plan B One-Step) and ulipristal acetate (ella). While these medications are generally safe for most individuals, concerns about their frequency of use and potential health impacts are valid and worth discussing.

First, it's important to understand how emergency contraceptives work. Levonorgestrel primarily works by preventing ovulation; if taken before ovulation, it can stop the release of an egg. Ulipristal acetate, on the other hand, can delay ovulation even if the luteinizing hormone (LH) surge has begun, making it effective closer to the time of ovulation. Neither of these medications is intended for regular use and should not replace a regular contraceptive method.

Regarding your specific situation, taking emergency contraceptives on two occasions within a few months is not uncommon, especially if you are using condoms as your primary method of contraception. However, repeated use of emergency contraceptives can lead to some side effects, although they are generally not harmful in the long term. Common side effects include:
1. Menstrual Changes: You may experience changes in your menstrual cycle, such as earlier or later periods, heavier or lighter bleeding, or spotting between periods. This is usually temporary and should normalize in subsequent cycles.

2. Nausea and Vomiting: Some individuals may experience nausea or vomiting after taking emergency contraceptives. If vomiting occurs within two hours of taking the pill, it may not be effective, and you should consult a healthcare provider.

3. Fatigue and Headaches: Some users report feeling tired or experiencing headaches after taking the medication. These symptoms are typically mild and resolve on their own.

4. Breast Tenderness: Hormonal changes can lead to breast tenderness, which usually subsides after a few days.

While occasional use of emergency contraceptives is not harmful, relying on them frequently can indicate a need for a more reliable contraceptive method. Emergency contraceptives are not as effective as regular contraceptive methods and should not be used as a primary form of birth control. If you find yourself needing to use emergency contraception multiple times, it may be beneficial to explore other contraceptive options that suit your lifestyle and health needs better.

In terms of long-term health effects, research indicates that emergency contraceptives do not have lasting negative impacts on fertility or overall health. They do not cause abortion and are safe for most individuals, including those who may have health conditions. However, if you have specific health concerns or conditions, it is always best to consult with a healthcare provider for personalized advice.

In conclusion, while using emergency contraceptives on two occasions is not likely to harm your health, it is essential to consider a more consistent contraceptive method to avoid the need for emergency contraception in the future. If you have ongoing concerns about your reproductive health or contraceptive options, I recommend scheduling an appointment with a healthcare provider who can provide tailored advice based on your individual circumstances.
