Hi, I understand your query. - Non responding / recurring yeast infection can occure due to few things which alter vaginal PH & make the yeast survival easy . They are- taking antibiotic / Hormone therapy or pregnancy, Diabetes or Hiv infection. So management of these things with your doctor s advise along with treatment of yeast infection is needful. Another factor ,which needs to be considered is - infection of the sex partner.So treatment of both sex partners at the same time & observing abstinence till infection is cured is important. Both oral pills along with vaginal pessaries ( metranidazole or Flucanozole) / maintaining good genital hygiene & treatment of both sex partners and managing other precipitating factors will help you. Thanks.
