Is Flagyl Effective for Treating Recurrent Yeast Infections? - Obstetrics and Gynecology

Share to:

Flagyl (metronidazole) is not typically used to treat yeast infections. It is primarily effective against bacterial infections and certain parasitic infections. For yeast


Hello Doctor, I often experience recurrent yeast infections and have undergone various tests.
I have come to accept this frustrating issue.
My gynecologist in the U.S.
suggested that if I have a recurrence, I can go to the pharmacy to purchase the medication he recommended: 1 tablet of Diflucan 150mg.
Yesterday, I went to the pharmacy and they recommended Flagyl 250mg per tablet, with a dosage of 14 tablets, taking one after breakfast and one after dinner.
However, upon further research, I found that this medication is not intended for yeast infections and could promote the growth of Candida.
Should I continue taking this medication? Thank you for your guidance.

Hello: Please come for a consultation.
If the examination reveals candidal vaginitis, it is recommended to use antifungal vaginal suppositories, and generally, oral antifungal medications are not necessary.
If it is trichomoniasis, it is advised to use oral metronidazole (Flagyl).
If the treatment is ineffective, it will be recommended for both partners to take the medication together.

More Info


Flagyl, also known as metronidazole, is an antibiotic that is primarily used to treat infections caused by anaerobic bacteria and certain parasites. It is not effective against yeast infections, which are typically caused by Candida species, most commonly Candida albicans. The confusion arises because both bacterial and yeast infections can occur in similar areas of the body, particularly in the vaginal environment, but they require different treatments.

In your case, it seems that you have been experiencing recurrent yeast infections, and your gynecologist recommended Diflucan (fluconazole), which is an antifungal medication specifically designed to treat yeast infections. Diflucan works by inhibiting the growth of fungi, making it effective against Candida species. On the other hand, Flagyl is not only ineffective for treating yeast infections, but it can also disrupt the normal flora of the vagina, potentially leading to an overgrowth of yeast.

The recommendation you received from the pharmacy to take Flagyl for a yeast infection is concerning. It is crucial to follow the advice of your healthcare provider, especially when it comes to treating recurrent infections. If your gynecologist has prescribed Diflucan, that is the medication you should take for your yeast infection. Taking Flagyl could complicate your condition rather than help it.

Recurrent yeast infections can be frustrating and may require a comprehensive approach to treatment and prevention. Here are some additional considerations that may help manage and reduce the frequency of yeast infections:
1. Identify Triggers: Common triggers for yeast infections include antibiotic use, hormonal changes (such as those related to menstruation or pregnancy), diabetes, and a weakened immune system. Keeping a diary of your symptoms and potential triggers can help identify patterns.

2. Dietary Changes: Some studies suggest that reducing sugar intake may help decrease the frequency of yeast infections, as yeast thrives on sugar. Incorporating probiotics, either through supplements or fermented foods, may also help maintain a healthy balance of vaginal flora.

3. Proper Hygiene: Maintaining good hygiene is essential. This includes wearing breathable cotton underwear, avoiding douching, and using mild soaps without fragrances.

4. Consult with Your Doctor: If you continue to experience recurrent yeast infections despite treatment, it may be worth discussing with your healthcare provider the possibility of a longer course of antifungal treatment or exploring other underlying conditions that may be contributing to the problem.

5. Partner Treatment: In some cases, if you have recurrent infections, it may be beneficial for your sexual partner to be evaluated and treated as well, especially if they are experiencing symptoms.

In conclusion, you should not continue taking Flagyl for your yeast infection. Instead, follow your gynecologist's advice and use Diflucan as prescribed. If you have any doubts or concerns about your treatment plan, it is always best to consult with your healthcare provider for clarification and guidance tailored to your specific situation.
