From the Guidelines
Topical azole antifungals are the first-line treatment for vaginal candidiasis during pregnancy, with clotrimazole 1% cream applied intravaginally for 7 days being a recommended option. According to the 2021 Centers for Disease Control and Prevention guidelines, as reviewed in the 2022 study 1, clotrimazole 1% cream can be applied intravaginally daily for 7–14 days. Other effective options include miconazole 2% cream for 7 days or 100mg vaginal suppositories for 7 days. These treatments typically resolve symptoms within a few days, though the full course should be completed.
Key Considerations
- Oral fluconazole (150mg single dose) should be avoided during pregnancy due to potential fetal risks, as noted in the guidelines 1.
- For severe or recurrent infections, longer treatment courses of 10-14 days may be necessary.
- Symptoms like itching, burning, and discharge should improve within 2-3 days of starting treatment.
- Partners generally don't require treatment unless they have symptoms.
- Prevention strategies include wearing cotton underwear, avoiding tight clothing, and maintaining good hygiene.
Treatment Options
- Clotrimazole 1% cream: 5 g intravaginally daily for 7–14 days
- Miconazole 2% cream: 5 g intravaginally daily for 7 days
- Miconazole 100 mg vaginal suppository: One suppository daily for 7 days
- Butoconazole 2% cream: 5 g intravaginally in a single application
- Terconazole 0.4% cream: 5 g intravaginally daily for 7 days Topical azoles are preferred during pregnancy because they have minimal systemic absorption while effectively treating the local infection, making them safe for both mother and fetus, as supported by the study from 1993 1.
From the FDA Drug Label

From the Research
Treatment Options for Vaginal Candidiasis in Pregnancy
- Imidazole drugs are more effective than nystatin for treating vaginal candidiasis in pregnancy, as shown in studies 5, 6.
- Clotrimazole is more effective than placebo, with an odds ratio of 0.14 and a 95% confidence interval of 0.06 to 0.31 5, 6.
- Single-dose treatment is less effective than three or four days of treatment, and four days of treatment is less effective than seven days of treatment 5, 6.
- Treatment for seven days may be necessary in pregnancy, rather than the shorter courses commonly used in non-pregnant women 5, 6.
Comparison of Treatment Methods
- Miconazole nitrate administered intravaginally has been found to achieve comparable therapeutic and mycological cure rates in both pregnant and nonpregnant women 7.
- A single oral dose of fluconazole is more effective than intravaginal clotrimazole in the long term, relieves symptoms more rapidly, and is as safe as treatment with intravaginal clotrimazole 8.
- Vaginal treatment with metronidazole and miconazole nitrate is as effective as vaginal plus oral treatment with fluconazole in all three trimesters, with no significant differences in recurrence of VVC 9.
Safety and Efficacy of Treatment
- Local treatment of VVC has several advantageous features, including a low rate of adverse events, safe utilization during pregnancy, and breastfeeding 9.
- Topical imidazole appears to be more effective than nystatin for treating symptomatic vaginal candidiasis in pregnancy, with treatments for seven days may be necessary 5, 6.
