In a 28-year-old pregnant woman in the second trimester with itching and thick, odourless vaginal discharge, what regimen is considered appropriate treatment for vaginal thrush?

• A. Clotrimazole pessary 500 mg intravaginally at night for 7 consecutive nights and clotrimazole 2% cream two to three times a day
• B. Fluconazole 150 mg orally as a single dose
• C. Nystatin vaginal tablet daily for 3 days
• D. Miconazole vaginal cream nightly for 3 days

Answer: (A)

In pregnancy, treating vaginal thrush focuses on safety for the fetus, so systemic antifungals are avoided and topical treatments are preferred. Clotrimazole is a safe, commonly used topical azole during pregnancy. Delivering the antifungal directly inside the vagina with a 500 mg pessary for a full 7 days ensures high local drug exposure to clear the infection. Adding a clotrimazole 2% cream provides relief for external itching and discharge, addressing symptoms from all surfaces involved. This combination targets the infection thoroughly over a full course, which is particularly important in pregnancy when ensuring efficacy while avoiding systemic therapy. Oral fluconazole is not recommended in pregnancy due to potential risks to the fetus, and simpler or purely topical regimens may be less reliably effective.
