Does Fluconazole Work for Vaginal Yeast Infection-

In this article I’ll take a closer look at Fluconazole (sold as Diflucan), a common oral antifungal medication prescribed for vaginal yeast infection.


Studies show that a single dose of fluconazole (150mg) is effective in up to 80% of women with a vaginal yeast infection, which means that in 80% of cases Candida species were completely removed from the vagina.  


What’s more, research shows that a single dose of oral fluconazole is as effective as antifungal vaginal suppositories, such as clotrimazole. Fluconazole is:


  • easier to use than suppositories, which can cause some discomfort and be a bit messy


  • its price is comparable with that of antifungal suppositories


  • it’s got low incidence of side effects.


I also found an interesting study that focused on improving the effectiveness of fluconazole. They found out that women who took  a probiotic supplement with Lactobacillus rhamosus and Lactobacillus reuteri for 4 weeks following a single dose of fluconazole showed significantly fewer Candida cells in their vaginal discharge.  If you’re looking for the right probiotic supplement to treat or prevent vaginal yeast infections, check my article about the best probiotic supplements for vaginal yeast infection.

Is fluconazole safe in pregnancy and breastfeeding

Taking fluconazole is not recommended in pregnancy. A new study from 2016 shows that taking oral fluconazole in pregnancy can significantly increase the risk of spontaneous abortion. When it comes to physical defects in a baby, taking one 150 mg pill of  fluconazole to treat vaginal candidiasisis is considered safe.


Having said that, taking fluconazole during pregnancy is not recommended and it only should be prescribed to patients with potentially life-threatening infections.


Fluconazole is known to be excreted into mother’s milk and its effects on the nursing infant have not been investigated.  In the UK, women can continue breastfeeding after a single dose of up to 200 mg, but should discontinue after repeated dosing or after a high dose.


In the US it’s recommended to avoid taking fluconazole while nursing. Contact you doctor to find out what is the best option for you.

  • Hi.
    I started with a water infection & two antibiotics later gave me the yeast infection twice!
    I’ve just taken Fluconazole 24 hrs ago. Already my symptoms have eased. I’m also using a Lactobacillus pessary for 6 days and a Probiotic twice a day. I’m not sure just using the Fluconazole would work for me, it really all depends how clean your digestion is, the Candida also grows in your digestion with eating too much sugar or Food Intolerances.

  • Blessed to find your article.
    Recently I had VYI and I bought fluconazole (fonzela) I think.
    I was hoping for recovery since it’s my second day.
    Though I didn’t buy diflucan.

  • Hi Kams,

    I really enjoyed reading your article, I found it very interesting!
    I am prone to yeast vaginal infections like many women, I suppose and it get even worse with time. I’ve never used the Fluconazole before, but I would definitely give a try! You have given all the information required, so I don’t think I need to ask any question about it:) I have bookmarked your website so I can read more of your great articles later.
    Thank you very much for this awesome review!

    • Hi Daniella, I’m great you found some useful information in my article. Fluconazole is often the medication of choice by many doctors to treat a vaginal yeast infection because it’s very effective.

  • Does Fluconazole Work for Vaginal Yeast Infection? So important for women as a new drug I see that there are many precautions to also use.

    One of the important ones I saw was – Birth Control pills, that it can make them ineffective.

    My Question though – how superior is this to its Competition seeing the many precautions that have to be taken?

    • Hi Rowan, the most common competition to Fluconazole is Itraconazole, but studies show it’s not as effective as fluconazole. It’s very important that women are reminded by their doctors of pharmacists that it can affect the contraceptive pill, I’ve used fluconazole a few times and nobody told me about it.
