Use of contraceptive pills


Today, I went to the pharmacy to buy contraceptive pills (Levonorgestrel single tablet).
The pharmacist gave me a sugar-coated tablet of active ingredients to take together.
Can you explain why? Will it affect the efficacy of the contraceptive pill?

Dr. Zheng Shuwen reply Pharmacology


Hello: In response to your question, "Huo Xing Bi Tang Yi Ling" contains vitamins B1, B2, B6, and B12.
According to foreign literature, some women may experience lower levels of B vitamins after long-term use of oral contraceptives.
This phenomenon can vary among individuals, and not every woman taking contraceptives will experience it.
Supplementing with B vitamins can help maintain their levels in the bloodstream.
If you prefer not to take supplements, you can obtain the necessary nutrients through your diet by consuming foods such as milk, eggs, leafy greens, meat, seafood, or organ meats.
Taking both supplements and oral contraceptives will not affect the efficacy of the contraceptives.
If you have any further questions, feel free to call us during business hours.
Thank you.

Business hours: Monday to Tuesday: 08:30-22:00; Wednesday to Friday: 08:30-18:00; Saturday: 08:30-14:00.

When it comes to understanding the impact of sugar pills on the effectiveness of birth control, it's essential to clarify a few key points about how hormonal contraceptives work and the role of sugar pills in combination birth control methods.

First, hormonal contraceptives, such as those containing Levonorgestrel, are designed to prevent ovulation, thicken cervical mucus, and thin the uterine lining to prevent pregnancy. These medications are typically taken in a cycle, where active pills containing hormones are taken for a specific number of days, followed by a set of sugar pills (placebo pills) that do not contain any active ingredients. The sugar pills are included in the pack to help maintain a regular pill-taking routine and to allow for a withdrawal bleed, which mimics a natural menstrual cycle.

The sugar pills themselves do not have any contraceptive effect; they are essentially inert. Therefore, taking sugar pills does not diminish the effectiveness of the active hormonal pills taken earlier in the cycle. As long as the active pills are taken correctly and consistently, the contraceptive effectiveness remains intact, even during the sugar pill week.
In your case, if you were given a sugar-coated pill (like a sugar pill) alongside your Levonorgestrel, it is likely that the pharmacist provided it as a supplement or for another purpose unrelated to contraception. It's important to clarify with the pharmacist what the sugar pill is intended for. If it is simply a sugar pill, it should not affect the effectiveness of your birth control.

However, if you are taking any additional medications or supplements, it's crucial to inform your healthcare provider or pharmacist. Some substances can interact with hormonal contraceptives, potentially affecting their effectiveness. For example, certain antibiotics and herbal supplements like St. John's Wort can reduce the effectiveness of hormonal birth control.
Moreover, if you have any concerns about the effectiveness of your birth control method, it is advisable to consult with your healthcare provider. They can provide personalized advice based on your health history and any medications you are taking.

In summary, sugar pills included in a birth control regimen are designed to maintain a routine and allow for a withdrawal bleed without affecting contraceptive effectiveness. If you have received a separate sugar-coated pill, it is important to understand its purpose and ensure that it does not interact with your birth control method. Always consult with a healthcare professional for any concerns regarding medications and their interactions.
