Infection & Antibiotics


Hello Doctor, I have been taking the seven-day course of antibiotics prescribed by my doctor.
By the fourth or fifth day, the amount of yellow-green discharge decreased, but I still have some occasionally.
At the same time, my menstrual period started, which made it difficult for me to see the discharge and determine if I am still infected.
After finishing the antibiotics, I had a follow-up appointment and told the doctor that I still felt infected before my period, but I think I didn't express myself clearly, leading the doctor to misunderstand that I was still infected (but due to my period, I couldn't tell if there was still an infection).
So, I was given another seven-day course of antibiotics.
Should I continue taking them? I apologize for the inconvenience, but I find it hard to communicate clearly during face-to-face consultations, so I am seeking your advice online.

Hello, it is recommended to finish taking it.
If there are still any discomforts, it is advisable to see a gynecologist; otherwise, just monitor the situation.
Wishing you good health.

When it comes to understanding antibiotics and infections during menstruation, there are several important factors to consider. First, it’s essential to recognize that antibiotics are prescribed to treat bacterial infections, and their effectiveness can be influenced by various factors, including the timing of your menstrual cycle.

During menstruation, hormonal changes can affect the vaginal environment, which may lead to changes in discharge. It’s not uncommon for women to experience variations in the color and consistency of vaginal discharge throughout their menstrual cycle. Yellow-green discharge can indicate an infection, such as bacterial vaginosis or a sexually transmitted infection (STI), but it can also be influenced by hormonal fluctuations.

In your case, you mentioned that you were prescribed a seven-day course of antibiotics, and by the fourth or fifth day, you noticed a decrease in the amount of yellow-green discharge. This is a positive sign, as it suggests that the antibiotics may be working. However, the onset of your menstrual period complicates the situation, making it difficult to assess whether the infection has fully resolved.

It’s crucial to communicate effectively with your healthcare provider about your symptoms and concerns. If you feel that your doctor misunderstood your situation during your last visit, it might be helpful to clarify your symptoms when you return for a follow-up. You can explain that while you experienced a reduction in discharge, the onset of menstruation made it challenging to determine if the infection persisted.

Regarding the continuation of antibiotics, it’s essential to follow your doctor’s advice. If your doctor prescribed an additional seven days of antibiotics, it may be because they believe the infection has not fully resolved or because they want to ensure that any remaining bacteria are eradicated. It’s important to complete the full course of antibiotics as prescribed, even if you start feeling better, to prevent the development of antibiotic resistance and ensure that the infection is fully treated.

If you are still experiencing symptoms after completing the antibiotics, or if you have concerns about the effectiveness of the treatment, it’s crucial to follow up with your healthcare provider. They may recommend further testing, such as a vaginal swab or culture, to identify the specific bacteria causing the infection and determine the most appropriate treatment.

In summary, while menstruation can complicate the assessment of vaginal discharge and potential infections, it’s essential to communicate openly with your healthcare provider about your symptoms. Completing the prescribed course of antibiotics is crucial, and if you have ongoing concerns, don’t hesitate to seek further medical advice. Your health and well-being are paramount, and ensuring clear communication with your healthcare provider can help you receive the best possible care.
