Birth Control Pills: Side Effects and Usage Tips - Obstetrics and Gynecology

Share to:

Oral contraceptives


I have a few questions for the doctor:
1.
I am currently taking Medroxyprogesterone, and I am experiencing side effects such as unusual odor and vaginal dryness, which causes pain during intercourse.
Will switching to a different brand help alleviate these two side effects, or do all contraceptive pills have these side effects?
2.
Regarding the WINSTOP contraceptive pill taken for 21 days, if I consistently take it every day and start taking it on the fifth day of my menstrual cycle, will this affect its contraceptive effectiveness? Or do I need to finish the 21 days, take a seven-day break, and then start again on the eighth day to maintain daily contraceptive effectiveness?

Q, 20~29 year old female. Ask Date: 2017/08/28

2.
Regarding the WINSTOP contraceptive pill taken for 21 days, if I take it consistently every day and start on the fifth day of my menstrual cycle, will this affect its contraceptive effectiveness? Or do I need to finish the 21 days, take a seven-day break, and then start on the eighth day for the contraceptive effect to be effective daily? Answer: Taking it for 21 days and then having a seven-day break before starting on the eighth day will provide similar contraceptive effectiveness as starting on the fifth day of each cycle.

When it comes to understanding birth control pills, it's essential to recognize that while they are effective for preventing pregnancy, they can also come with a range of side effects. Your concerns about the side effects you are experiencing, such as unusual vaginal odor and dryness leading to painful intercourse, are valid and not uncommon among users of hormonal contraceptives.

1. Side Effects of Birth Control Pills: The side effects you mentioned can indeed occur with many types of birth control pills, including those containing estrogen and progestin. Vaginal dryness and changes in vaginal flora can lead to discomfort and odor. Switching to a different brand or formulation may help alleviate these symptoms, as different pills have varying hormone levels and compositions. For instance, some pills are designed to have lower doses of estrogen or to use different types of progestin, which might be less likely to cause dryness. It’s advisable to consult with your healthcare provider about your symptoms; they can suggest alternative options that may be better suited for you.

2. Usage of WINSTOP Birth Control Pills: Regarding the WINSTOP birth control pills, it’s crucial to follow the prescribed regimen for optimal effectiveness. Typically, birth control pills are taken for 21 consecutive days, followed by a 7-day break during which you would experience withdrawal bleeding. If you start taking the pills on the fifth day of your menstrual cycle, you should still maintain the 21-day regimen followed by a 7-day break. If you take the pills consistently every day as directed, the contraceptive effectiveness should remain intact. However, if you start the pills at a different time or do not follow the regimen correctly, it could potentially reduce their effectiveness.
It’s also important to note that if you miss a pill or take it at irregular times, it can compromise the effectiveness of the birth control method. If you have any doubts about your specific situation, such as when to start taking the pills or how to manage missed doses, it’s best to consult with your healthcare provider for personalized advice.

In summary, while birth control pills are a reliable method of contraception, they can have side effects that vary from person to person. If you are experiencing discomfort, switching brands may be beneficial. Additionally, adhering to the prescribed regimen is crucial for maintaining contraceptive effectiveness. Always feel free to reach out to your healthcare provider with any concerns or questions regarding your birth control method. They can provide guidance tailored to your health needs and help you find the most suitable option for you.
