Risks of Using Emergency Contraceptive Pills


Hello Doctor: I would like to ask a few questions regarding preconception contraceptive pills.

1.
Is it advisable for individuals with a family history of breast cancer to use preconception contraceptive pills? (After researching online, I found conflicting information and am unsure which is correct.)
2.
How long should preconception contraceptive pills be used before discontinuation? If discontinuation is recommended, is there a suggested duration for stopping and resuming use?
3.
If I stop taking preconception contraceptive pills for one month, when should I start taking them again the following month? Should I begin on the first day of my menstrual cycle?
4.
I am currently taking "Yue Ji" (a brand of contraceptive pill).
To reduce the risk of breast cancer and thrombosis, should I switch to a lower-dose contraceptive pill from another brand?
Thank you for your response, Doctor!

Dr. Huang Yuande reply Obstetrics and Gynecology


For individuals with a family history of breast cancer, it is important not to forget routine screenings.
In general, excessive supply of female hormones should be avoided.
Birth control pills are synthetic estrogens or progestins and typically do not increase the cancer risk for women with a family history.
Since there are many types of birth control pills available on the market, with varying compositions, it is recommended to refer to the information provided in the package insert.
Thank you for your inquiry.

When it comes to understanding the risks and considerations surrounding emergency contraceptive pills (ECPs), it's essential to address several key questions that often arise among individuals considering their use. Here, I will provide insights based on current medical knowledge and guidelines.

1. Family History of Breast Cancer and ECP Use: Individuals with a family history of breast cancer often have concerns about using hormonal contraceptives, including ECPs. Current medical guidelines suggest that while there is a theoretical concern regarding the use of estrogen-containing contraceptives in women with a family history of breast cancer, the evidence is not definitive. The risk of breast cancer associated with hormonal contraceptives is generally considered low, especially for short-term use like ECPs. However, it is crucial for individuals with such a family history to discuss their specific risks with a healthcare provider, who can provide personalized recommendations based on their health history and family background.

2. Duration of ECP Use: Emergency contraceptive pills are intended for occasional use and are not designed for regular contraception. If someone is using ECPs frequently, it may indicate a need for a more reliable form of contraception. There is no specific duration for which ECPs should be taken, as they are meant for emergency situations only. If someone finds themselves needing ECPs repeatedly, it is advisable to consult with a healthcare provider to explore long-term contraceptive options.

3. Starting ECPs After a Break: If an individual stops taking ECPs and wishes to start again, they should ideally begin taking the pills at the start of their next menstrual cycle. This typically means starting the pills on the first day of menstruation. However, if there is any uncertainty about the timing or the menstrual cycle, it is best to consult with a healthcare provider for tailored advice.

4. Switching to Lower-Dose Contraceptives: If there are concerns about the risks of breast cancer and thrombosis associated with certain contraceptives, it may be reasonable to consider switching to a lower-dose hormonal contraceptive. Many modern contraceptives are available in lower doses of estrogen and progestin, which can reduce the risk of side effects while still providing effective contraception. Again, this decision should be made in consultation with a healthcare provider, who can assess individual risk factors and recommend the most appropriate contraceptive method.

In summary, while emergency contraceptive pills are a safe and effective option for preventing pregnancy after unprotected intercourse, individuals should be aware of their personal health history and any family medical history that may influence their contraceptive choices. Regular consultations with a healthcare provider can help ensure that individuals make informed decisions about their reproductive health, including the choice of contraceptive methods that best suit their needs and minimize potential risks.
