Hypersensitivity to butoconazole or any component of the formulation.
Documentation of allergenic cross-reactivity for imidazole antifungals is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Vulvovaginal candidiasis: Intravaginal: Insert 1 applicatorful (∼5 g) intravaginally as a single dose. Note: A longer duration may be necessary in patients with complicated infection (ie, recurrent or severe infection, infection with non-albicans Candida, or infection in an immunocompromised host) (CDC [Workowski 2015]; HHS [OI adult 2020]).
Refer to adult dosing.
Intravaginal: Use applicator provided by manufacturer. Do not use applicator if tip has been removed. Do not warm applicator prior to administration. Insertion should be as far as possible into the vagina without causing discomfort.

Dosage form specific issues:
• Vaginal cream: Contains mineral oil that may weaken latex or rubber (condoms or diaphragms); use of these products within 72 hours of treatment is not recommended.
• HIV infection consideration: HIV infection should be considered in sexually-active women with difficult to eradicate recurrent vaginal yeast infections.
This product may weaken latex or rubber condoms or diaphragms (CDC [Workowski 2015]).
Pregnancy Risk Factor
Adverse events have been observed in some animal reproduction studies. Following vaginal administration, small amounts are absorbed systemically. Single dose, topical azole regimens are not recommended for the treatment of vulvovaginal candidiasis; only topical azole therapies with 7 day regimens are recommended in pregnant women with vulvovaginal candidiasis (CDC [Workowski 2015]).
