Question for Betty.
 

How long can a yeast infection last?  Why, when I did take medication for it, didn't it clear up?

 
Betty's Answer.
 

Vaginal yeast infections, also called vulvovaginal candidiasis (VVC), are very common, affecting up to 75% of women at least once in their lifetimes.  Women sometimes believe they have a yeast infection, and they really have another type of infection, such as, bacterial vaginosis, or genital herpes. 

40-50% of women have a recurrence of VVC after self-treatment with over the counter antifungal products, or with prescription products.

Risk factors may include taking certain antibiotics or higher dose OCPs. You are also at risk if you have a current infection with chlamydia, GC, or bacterial vaginosis.  Use of spermicides, feminine hygiene products or douching increase risk.  Receptive oral sex increases risk.  Pantyliner and pantyhose use increase risk.  And, such conditions as diabetes, HIV, and pregnancy, increase risk. 

For an infection that hasn't cleared up after use of Fuconazole 100mg, or OTC antifungal treatment, you will want to return to your health care provider or the SHCC for a vaginal infection check to confirm that it is a yeast infection.  If it is indeed still yeast, than it can be treated with Fluconazole 100mg for a longer period of time, or treated with other medications.
