Vulvovaginal candidiasis (VVC), also known as moniliasis, is a type of yeast infection affecting the vulva and vagina. Yeast is a form of fungus, which is why this condition during pregnancy is commonly referred to as a “vaginal yeast infection in pregnancy.” The yeast most often responsible is Candida albicans, although other species—such as Candida glabrata and Candida tropicalis—can also cause these infections.
Statistics show that in the United States, three out of every four women experience at least one yeast infection in their lifetime, and up to 45 percent develop two or more episodes.
During pregnancy, Candida-related infections become even more common. While about 20 percent of women naturally carry Candida yeast in the vagina, this number increases to around 30 percent during pregnancy. Due to hormonal fluctuations, the yeast can overgrow and lead to infection.
Because one of the complications of vaginal yeast infection during pregnancy is the possibility of transmitting the yeast to the baby during birth, timely treatment is very important.
The primary cause of vaginal yeast infections during pregnancy is hormonal changes, which alter the pH balance of the vagina. This creates an environment that is more favorable for yeast growth. In addition, vaginal secretions contain higher levels of sugar during pregnancy, providing a food source that allows yeast to multiply more rapidly.
In general, the causes of vaginal yeast infection during pregnancy may be due to one or more of the following factors:

A doctor can examine your symptoms and prescribe the appropriate treatment for a yeast infection. However, if you have symptoms similar to a yeast infection during pregnancy but your doctor has ruled it out, you may be experiencing one of the following:
At the doctor’s office or a medical clinic, the specialist typically uses a simple, painless swab to collect a sample of vaginal discharge and examine it under a microscope. In most cases, a routine vaginal examination is enough for the doctor to diagnose a yeast infection. In rare situations, the sample may be sent to a laboratory for culture.
For treating vaginal yeast infections during pregnancy, doctors generally recommend only vaginal creams and suppositories. There is no scientific evidence confirming the safety of oral medications—such as the single‑dose drug Diflucan—during pregnancy or breastfeeding, which is why they are not prescribed. At the same time, not all vaginal creams and suppositories are considered safe for use during pregnancy, so it is best to consult your obstetrician or pharmacist to receive the appropriate medication.
Some people use medication on their own to treat a vaginal yeast infection during the first month of pregnancy or the first trimester. Although your doctor may prescribe certain antifungal treatments that are safe during pregnancy, you should never use them without consulting a healthcare professional.
It may take 10 to 14 days for a dermatologist or obstetrician to fully treat a vaginal yeast infection during pregnancy. After the infection clears and the irritation heals, using a non‑starch drying powder or nystatin powder may help prevent recurrence.
Over‑the‑counter medications available for treating vaginal yeast infections in the form of creams, ointments, or suppositories include:
These products can be used as ointments for treating vaginal yeast infections during all stages of pregnancy. They do not pose any risk of birth defects or pregnancy complications. For example, clotrimazole cream is commonly used by many pregnant women. However, you should always consult your doctor or pharmacist before using any medication.
If left untreated, yeast infections during pregnancy can lead to the yeast being passed to your baby during childbirth, causing a condition called “thrush,” which can be effectively treated with Nystatin.
