Femstat 3 is an over-the-counter treatment (OTC) for vaginal
yeast infections. While other OTC vaginal yeast infection
medications require 7 days of treatment, Femstat 3 vaginal cream
will be the first 3-day treatment brand available without a
prescription.
Femstat 3 contains the antifungal agent butoconazole nitrate,
which was developed specifically for the local treatment of vaginal
yeast infections.
Femstat 3 should be used vaginally by nonpregnant women and
girls age 12 and over.
Femstat 3 will be available in a 5-gram prefilled disposable
applicator, with three applicators packaged together as a treatment
regimen. Recommended dosage is one applicatorful each day for three
consecutive days, preferably at bedtime.
Since its introduction in prescription form in 1986, more than
13 million women worldwide have been treated with butoconazole
nitrate for vaginal yeast infections. The safety of prescription
butoconazole nitrate has been established in 45 clinical trials and
eight years of postmarketing experience in the U.S. and abroad.
These clinical studies included 3,267 subjects treated with
butoconazole nitrate; 1,735 subjects treated with other antifungal
agents; and 287 subjects treated with a placebo. In these 45
studies, the drug-related incidence of local adverse events, such
as burning and itching, was consistent with the market leader,
Monistat 7.
Two well-controlled clinical studies conducted in support of the
Rx-to-OTC switch application demonstrated that the 3-day regimen
with butoconazole nitrate 2% cream in over 300 subjects was as safe
and effective as the 7-day regimen of miconazole nitrate 2% cream
(Monistat 7) for the treatment of vulvovaginal candidiasis when
evaluated at 8 and 30 days post-treatment. The efficacy of
butoconazole nitrate in a 3-day regimen was also established in
clinical studies conducted in support of the original prescription
product. These NDA studies included more than 1,300 subjects,
nearly 900 of whom were treated with butoconazole nitrate 2%
cream.
Between 1980 and 1990, the incidence of vulvovaginal candidiasis
nearly doubled in the United States., with an annual occurrence of
13 million cases. OTC vaginal yeast infection products are intended
for use by women who have previously been diagnosed by a physician
as having a vaginal yeast infection and who are experiencing the
same symptoms again. Nonprescription Femstat 3 is the result of the
prescription-to-OTC switch of the prescription products, Femstat
and Femstat Prefill.
First-time sufferers should see a doctor. Femstat 3 should not
be used if experiencing abdominal pain, fever, or foul-smelling
discharge. A physician should be contacted immediately. If the
infection isn't gone in three days, there may be a condition
other than a yeast infection or the use of more medication may be
needed. A doctor should be consulted. If symptoms return within two
months or if women think they have been exposed to the HIV virus
that causes AIDS, a doctor should be consulted immediately.
Recurring infections may be a sign of pregnancy or a serious
condition, such as AIDS or diabetes. Product should not be used if
a woman is pregnant or thinks she may be pregnant, has diabetes, a
positive HIV test or AIDS. Condoms or diaphragms should not be
relied upon to prevent sexually transmitted diseases or pregnancy
while using this product. This product may damage condoms and
diaphragms and may cause them to fail. Another method of birth
control should be used to prevent pregnancy while using this
product. Femstat 3 should not be used with tampons. This product
should not be used in girls under 12 years of age.
