From the Guidelines

The first-line treatment for a Candida vaginal infection is typically an antifungal medication such as fluconazole, a single 150 mg oral dose, or topical azole treatments like clotrimazole, miconazole, or terconazole applied intravaginally for 1-7 days depending on the specific formulation. For mild to moderate infections, either oral fluconazole or a topical azole is equally effective, with cure rates of approximately 80-90% 1. Topical options include:

  • Clotrimazole 1% cream (5g intravaginally for 7-14 days)
  • Clotrimazole 2% cream (5g intravaginally for 3 days)
  • Miconazole 2% cream (5g intravaginally for 7 days)
  • Terconazole 0.4% cream (5g intravaginally for 7 days)
  • Fluconazole 150 mg, single dose orally 1. For severe infections or recurrent cases, an extended regimen may be necessary, such as fluconazole 150 mg every 72 hours for three doses 1. These medications work by disrupting the fungal cell membrane, preventing the yeast from growing and reproducing. During treatment, patients should avoid douching, use unscented soaps, wear cotton underwear, and may need to temporarily avoid sexual intercourse or use condoms to prevent reinfection or irritation.

From the FDA Drug Label

Fluconazole tablets are indicated for the treatment of: Vaginal candidiasis (vaginal yeast infections due to Candida). In Patients Receiving a Single Dose for Vaginal Candidiasis: During comparative clinical studies conducted in the United States, 448 patients with vaginal candidiasis were treated with fluconazole, 150 mg single dose.

The first-line treatment for a Candida (fungal) vaginal infection is fluconazole, specifically a 150 mg single dose 2. This is a well-tolerated treatment, with the most common side effects being headache, nausea, and abdominal pain 2. Fluconazole is indicated for the treatment of vaginal candidiasis (vaginal yeast infections due to Candida) 2.

From the Research

Tratamiento de Candida vaginal

  • El tratamiento de primera línea para una infección vaginal por Candida (fúngica) puede variar dependiendo de la gravedad de la infección y la historia médica de la paciente.
  • Según un estudio publicado en el American Journal of Obstetrics and Gynecology en 1995 3, un solo dosis oral de 150 mg de fluconazol es tan seguro y efectivo como 7 días de tratamiento intravaginal con clotrimazol para la candidiasis vaginal.
  • Otro estudio publicado en The New England Journal of Medicine en 2004 4 encontró que el tratamiento con fluconazol una vez a la semana durante seis meses puede reducir la tasa de recurrencia de la candidiasis vaginal sintomática.
  • Un estudio publicado en Mycoses en 1992 5 comparó el tratamiento con un solo dosis oral de fluconazol con un tratamiento local de tres días con miconazol y encontró que ambos tratamientos eran efectivos, con tasas de curación clínica y micológica superiores al 80%.
  • Un estudio publicado en Chemotherapy en 1998 6 comparó tres regímenes de tratamiento para la candidiasis vaginal y encontró que el tratamiento oral con itraconazol o fluconazol era efectivo, con tasas de erradicación de Candida species del 74-80% y tasas de efectividad clínica del 76-92%.
  • En general, los tratamientos antifúngicos orales como el fluconazol y el itraconazol pueden ser una opción efectiva para el tratamiento de la candidiasis vaginal, especialmente en casos de infecciones recurrentes o graves 3, 4, 5, 6.
  • Sin embargo, es importante tener en cuenta que la elección del tratamiento debe individualizarse según la gravedad de la infección, la historia médica de la paciente y sus preferencias personales 3, 7.
