I always wondered, why bother having Monistat 7? It takes 5 days longer to cure than Monistat 3. So why would any woman conceivably purchase the slower method? Are yeast infections some sort of rare enjoyment? I wouldn’t think so. So, why in the world would anyone get the 7 day cure, rather than the 3 day cure? It just doesn’t make any sense.
Just wait until you get a load of Monistat 100!
From the CDC ( http://www.cdc.gov/std/treatment/5-2002TG.htm#VulvovaginalCandidiasis)
Treatment of uncomplicated vulvovaginal candidiasis (VVC)
“Short-course topical formulations (i.e., single dose and regimens of 1–3 days) effectively treat uncomplicated VVC. The topically applied azole drugs are more effective than nystatin. Treatment with azoles results in relief of symptoms and negative cultures in 80%–90% of patients who complete therapy.”
Complicated VVC
"Recurrent Vulvovaginal Candidiasis
Recurrent VVC (RVVC), usually defined as four or more episodes of symptomatic VVC each year, affects a small percentage of women (<5%). The pathogenesis of RVVC is poorly understood, and most women who have RVVC have no apparent predisposing or underlying conditions. Vaginal cultures should be obtained from patients with RVVC to confirm the clinical diagnosis and to identify unusual species, including non-albicans species, particularly Candida glabrata (C. glabrata does not form pseudohyphae or hyphae and is not easily recognized on microscopy). C. glabrata and other non-albicans Candidia species are found in 10%–20% of patients with RVVC. Conventional antimycotic therapies are not as effective against these species as against C. albicans.
Treatment
Each individual episode of RVVC caused by C. albicans responds well to short duration oral or topical azole therapy. However, to maintain clinical and mycologic control, specialists recommend a longer duration of initial therapy (e.g., 7–14 days of topical therapy or a 150-mg, oral dose of fluconazole repeated 3 days later) to achieve mycologic remission before initiating a maintenance antifungal regimen."
