Recurrence of vulvovaginal candidiasis is particularly likely if there are predisposing factors, such as antibacterial therapy, pregnancy, diabetes mellitus, or possibly oral contraceptive use (1)

  • reservoirs of infection may also lead to recontamination and should be treated; these include other skin sites such as the digits, nail beds, and umbilicus as well as the gastro-intestinal tract and the bladder
  • the partner may also be the source of re-infection and, if symptomatic, should be treated with a topical imidazole cream at the same time.

Treatment against candida may need to be extended for 6 months in recurrent vulvovaginal candidiasis.

Some alternative recommended regimens include (1):

  • initially, fluconazole by mouth 150 mg every 72 hours for 3 doses, then 150 mg once every week for 6 months;

  • initially, intravaginal application of a topical imidazole for 10-14 days, then clotrimazole vaginally 500-mg pessary once every week for 6 months;

  • initially, intravaginal application of a topical imidazole for 10-14 days, then itraconazole by mouth 50-100 mg daily for 6 months.

Public Health England guidance states:

If recurrent vaginal candidiasis

  • fluconazole (induction/maintenance)
    • 150mg every 72 hours for 3 doses THEN 150mg once a week

A systematic review showed that weekly treatment with fluconazole (150 mg) for six months was effective against recurrent vulvovaginal candidiasis (2).

Patients with recurrent vaginal thrush can be advised on self-help measures. These may include:

  • if there is any bowel reservoir of organisms then consider treatment with oral antifungals will treat bowel infection
  • treatment of male sexual partner (treatment is simultaneous)
  • avoid precipitating factors e.g. tight fitting clothes,
  • the use of natural yoghurt (taken orally or given intravaginally) - the bacteria in the yoghurt apparently produce pH changes in the vagina that discourage the growth of candida
  • diabetes must be excluded
    • a large proportion of vulvovaginal candidiasis in diabetes is due to non-albicans Candida species such as C. glabrata (3)
    • observational studies indicate that diabetic patients with C. glabrata vulvovaginal candidiasis respond poorly to azole drugs
