Which antibiotics cause yeast infection: Can antibiotics cause yeast infections?

Do Antibiotics Cause Yeast Infections?

About one-quarter to one-third of women will get a yeast infection after taking antibiotics. The vagina always has low levels of yeast, but it’s suggested that broad-spectrum antibiotics — those that target a variety of different bacteria because doctors aren’t positive about which might be causing an infection — will kill the good bacteria in the vagina. This “good” bacteria is called lactobacilli, and it prevents the overgrowth of yeast by keeping the vagina slightly acidic. Start targeting that bacteria, and yeast will overgrow.

The longer you take antibiotics, the more likely you are to develop a yeast infection because of how it affects the balance of the vaginal flora, Anna Maya Powell, MD, MS, assistant professor of gynecology and obstetrics at Johns Hopkins Medicine, told POPSUGAR. Examples of broad-spectrum antibiotics that may cause yeast buildup include, Dr. Powell said, tetracyclines, typically used to treat acne, UTIs, STIs, etc. , and cephalosporins, used to treat some UTIs, infections of the ears, skin, sinuses, and others. That being said, Meera Garcia, MD, assistant professor of obstetrics and gynecology at Columbia University Irving Medical Center, told POPSUGAR that though the antibiotics with a “wider spectrum of kill” will usually have increased potential for causing yeast buildup, it all depends on the interaction between the antibiotics and the person.

Risk Factors For Developing Yeast Infections While on Antibiotics

If you are someone who’s prone to yeast infections, then you’re more likely to get one while on antibiotics, both doctors agreed. Both also mentioned diabetes as another risk factor. “When a woman is diabetic, she has issues with her metabolism and her blood sugar can go up. Yeast feeds off of that sugar,” Dr. Garcia said.

Dr. Powell noted that if you’ve had a yeast infection from antibiotics before, you’re more prone to it happening again. And, when someone is being treated for bacterial vaginosis, a common vaginal infection characterized by the overgrowth of bacteria, topical clindamycin (antibiotics) can also cause symptoms of a yeast infection, she said.

How to Prevent a Yeast Infection While Taking Antibiotics

Some patients who are prone to yeast infections can simply take a one-dose antifungal medication, Diflucan, at the same time as their antibiotics, both doctors said. Taking antifungal medication and antibiotics simultaneously is safe, though they cautioned against doing so if you’re pregnant. And, if you’re taking any medication that might interfere, ask your doctor first. Dr. Garcia said that, in the rare case that you have hepatic failure (liver failure), you shouldn’t take both antibiotics and antifungal medication because they’re typically metabolized by the liver. “For someone with liver issues, we might have them finish out their antibiotics . . . and then take the antifungal medication,” she noted.

Dr. Garcia offered more tips below:

  • Don’t take baths. When people take baths, they normally do so to clean their bodies as well as soak, she said. “Water itself has a pH of seven, which is definitely much less acidic than the vagina. On top of that, if you put conditioner and soap . . . the water becomes very basic in nature. That water could go up inside the vagina or lap around the vulvar area, and it kills the bacteria, especially lactobacilli.” Products like shaving cream can also interfere with good bacteria because it, like soap, brings the pH of the vagina up.
  • Take a probiotic. Research is limited, but Dr. Garcia recommends taking a probiotic every day while you’re on antibiotics because it’ll help restore the balance of the vaginal flora. This means restoring the good bacteria that controls the growth of yeast. (Dr. Powell noted that it’s unclear whether taking oral probiotics actually gets enough of the good bacteria into the vagina). Dr. Garcia said that you can actually take a probiotic by vagina, too. There’s also, she said, boric acid. “When it’s taken by mouth, it’s poisonous, but when taken as suppository, it brings the pH down to lab-grade acid. And, when the vagina is at that level, it prevents the overgrowth of yeast.”

How to Treat a Yeast Infection Caused by Antibiotics

To treat a yeast infection, whether or not it was caused by antibiotics, Diflucan is recommended. Dr. Garcia noted that sometimes people prefer creams in the vagina that tend to give symptomatic relief as well. “One is called Terconazole or Terazol, and you can do a three-day course or a four-day course.”

For people with recurrent yeast infections, one of the maintenance regimens is weekly Diflucan that you can use for up to six months at a time, Dr. Powell said. And, remember, if you are prone to yeast infections and are prescribed antibiotics for a bacterial infection, you should consider requesting an antifungal medication that you could take at the same time because, Dr. Powell said, that’s probably the most effective. “Then, if you develop a yeast infection while you’re on antibiotics, you should contact your provider to be treated for that.”

Another thing to remember, per Dr. Powell: try to avoid self-diagnosis. Studies show that patients are not very good at self-diagnosing vaginitis infections (inflammation of the vagina that causes discharge, itching, etc.) because the symptoms are pretty vague, she said. “The top three causes of vaginitis are yeast, bacterial vaginosis, and trichomoniasis, and a lot of the symptoms cross over for all three,” she said. “Not to say that somebody would get a trich infection after being on [antibiotics], but it could also be just an irritation, or there’s a lot of reasons why women are seeing abnormal discharge.” When in doubt, though, contact your doctor.

Vaginal candidiasis is a common infection in women. The microflora of the vagina are influenced by a number of factors, including pregnancy, oral contraceptive use, menses and diabetes mellitus. Previous antibiotic use is generally accepted to be a risk factor for vaginal candidiasis but the published evidence to support this is limited.


To determine the relative risk of vaginal candidiasis following the use of antibiotics compared with antidepressants in prescription-event monitoring (PEM) studies.


Using data from postmarketing surveillance studies of six antibiotics and six antidepressants, conducted using the observational cohort technique of PEM, the number of reports of vaginal candidiasis was determined in women aged > or =16 years, in each of the first 7 weeks following a prescription for one of these drugs. The relative risks for vaginal candidiasis following the use of these antibiotics and for each of the individual antibiotics compared with antidepressants were calculated for each week and for the overall 7-week period. Women treated with antidepressants were the most suitable comparator group from the PEM database, as they were of a similar age range and the studies were conducted at a similar time period to those of the antibiotics. Also, there was no pharmacological plausibility for vaginal candidiasis being associated with antidepressants.


There were 188 reports of vaginal candidiasis in 31 588 women, aged > or =16 years, treated with antibiotics and 70 in the 45 492 treated with antidepressants. The relative risk for vaginal candidiasis (antibiotic/antidepressants), was highest in the second week, 10.70 (95% CI 4.86-23.55) but was also significantly greater in the first and third weeks after the start of treatment. The risk was also higher in each of the 3 weeks after starting the course for five of the antibiotics, compared individually to the group treated with antidepressants, the exception being fosfomycin, which had a much smaller cohort.


This study shows a significant increase in the risk of developing vaginal candidiasis following the use of the antibiotics studied (ciprofloxacin, ofloxacin, norfloxacin, cefixime, azithromycin and fosfomycin) compared with that after taking the antidepressants fluvoxamine, fluoxetine, paroxetine, sertraline, venlafaxine and nefazodine in these PEM studies.

Treatment of candidiasis (thrush), bacterial vaginosis, human papillomavirus in Naro-Fominsk

Treatment of candidiasis (thrush), bacterial vaginosis, human papillomavirus

Candidiasis or unfortunate thrush in women is a lesion of the vaginal mucosa by a yeast-like fungus of the genus Candida – microorganisms of conditionally pathogenic microflora. This means that fungi constantly live in a woman’s body in a certain amount.
However, under the influence of third-party factors, their concentration increases – the development of the pathological process starts.

Thrush and other pathologies of the vaginal mucosa can be diagnosed and treated quickly and effectively at the GlavVrach Medical Center in Naro-Fominsk. We care about every customer! Our patients come to us sick and leave healthy! Contact the GlavVrach employee right now, do not hesitate!

Medical treatment of candidiasis in women

As part of therapy, systemic preparations are used, the active components of which penetrate into the bloodstream and act on the provocateur of pathology. Among the representatives: Fluconazole, Flucostat.

In addition to the mentioned medicines, local remedies are involved in the treatment of thrush. They are not only detrimental to the pathogen, but are also able to restore the affected mucous membrane. Among these medicines: Natamycin, Pimafucin. Approximately the same mechanism of action differs in suppositories and vaginal tablets (Terzhinan, Polygynax).

Thrush and bacterial vaginosis are not the same thing

Bacterial vaginosis, like candidiasis, is a lesion of the vaginal mucosa, however, the causative agent in this case is a bacterium (Klebsiela, Bacteroid, Fusobacterium, etc.).

Accordingly, the treatment of bacterial vaginosis will be different. The role of the active component of most of the drugs used is metronidazole (Metrogil, Trichopolum, etc.).

Human papillomavirus treatment

Pathology develops in a woman’s body in response to the weakening of the patient’s immune system. Accordingly, the main task of HPV treatment is to influence the patient’s immunity while eliminating the manifestations of the disease.

The therapeutic course begins with vaccination. It is followed by taking antiviral and immunomodulatory drugs. Since bacterial infections often join the clinical picture with HPV, the patient is prescribed antibiotics. In the case of the formation of genital warts on the mucous membrane, local treatment is indicated (vaginal tablets, suppositories).
