Regarding contraception?


Hello, doctor.
I would like to ask: 1.
If I want to use contraception, is taking preemptive contraceptive pills less harmful to the body? 2.
If I take emergency contraceptive pills once a month, will it have negative effects on my health?

Winnie, 20~29 year old female. Ask Date: 2017/09/04

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, the general oral contraceptive pills should be taken within the first 1 to 5 days of the menstrual cycle and need to be taken daily, as each pill is effective for 36 hours.
Emergency contraceptive pills can provide protection against pregnancy from a single act of intercourse.
However, since emergency contraceptive pills primarily contain high doses of female hormones/progestins, they can cause side effects such as nausea, vomiting, and bloating.
Frequent use may not only lead to androgenic effects like oily skin and acne but can also disrupt normal ovarian function, resulting in irregular menstrual cycles.
If intimate encounters are frequent, it is advisable to establish a regular contraceptive method.
Thank you! Wishing you safety and health, Dr.
Zhang.

When it comes to understanding contraception, particularly the use of birth control pills and emergency contraceptive pills, it is essential to consider both their effectiveness and potential health impacts.
1. Safety of Regular Birth Control Pills: Birth control pills, particularly combined oral contraceptives (COCs), are generally considered safe for most women when taken as directed. These pills contain hormones (estrogen and progestin) that work primarily by preventing ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to prevent implantation. When taken consistently and correctly, COCs can be over 99% effective in preventing pregnancy.
The health risks associated with regular use of birth control pills are relatively low for most women. However, there are some contraindications, such as a history of blood clots, certain cancers, or severe hypertension, which may increase the risk of complications. It is crucial to consult with a healthcare provider to assess individual health conditions and determine the most suitable contraceptive method.
Additionally, the benefits of using birth control pills extend beyond pregnancy prevention. They can help regulate menstrual cycles, reduce menstrual cramps, and even lower the risk of certain reproductive cancers. Overall, for most women, taking regular birth control pills is a safe and effective method of contraception.

2. Impact of Emergency Contraceptive Pills: Emergency contraceptive pills (ECPs), often referred to as "morning-after pills," are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. They are most effective when taken as soon as possible after the incident, ideally within 72 hours, but some types can be effective up to five days later.

Taking ECPs occasionally is generally safe for most women and does not have long-term negative health effects. However, they are not intended for regular use as a primary contraceptive method. Frequent use of emergency contraception can lead to menstrual irregularities, such as changes in the timing of the next period, heavier or lighter bleeding, and potential nausea or fatigue.
While using ECPs once in a while is unlikely to cause significant harm, relying on them as a primary form of contraception is not advisable. They are less effective than regular contraceptive methods and can be more expensive over time. Furthermore, frequent use may indicate a need to reassess one’s contraceptive strategy to find a more reliable and consistent method.

In summary, regular birth control pills are generally safe and effective for preventing pregnancy and can offer additional health benefits. In contrast, emergency contraceptive pills are a safe option for occasional use but should not replace regular contraceptive methods. It is always best to discuss contraceptive options with a healthcare provider to ensure that the chosen method aligns with individual health needs and lifestyle.
