During a wellness examination, a 28-year-old female reports intense vaginal itching and a change in her vaginal discharge that began five days ago. She recently completed a 10-day course of amoxicillin-clavulanate for acute bacterial sinusitis. Her vital signs are within normal limits. Speculum examination reveals a normal-appearing cervix, marked vulvar erythema, and a thick, curd-like white vaginal discharge that adheres to the vaginal walls. The vaginal pH is 4.2. Which of the following is the most appropriate pharmacotherapy for this patient's current condition?
- AIntramuscular ceftriaxone
- BOral metronidazole
- Oral fluconazoleCevap
- DOral doxycycline
- ETopical clindamycin
Cevap
Oral fluconazole
The patient's clinical presentation of intense pruritus, vulvar erythema, and a thick, curd-like (cottage cheese) white discharge, combined with a normal vaginal pH (3.8-4.5), is highly characteristic of vulvovaginal candidiasis. The recent use of broad-spectrum antibiotics (amoxicillin-clavulanate) is a classic risk factor because it alters the normal vaginal flora, allowing Candida species to overgrow. The most appropriate first-line treatment is an antifungal agent such as oral fluconazole.
