Terconazole vaginal cream is indicated for the local treatment of vulvovaginal candidiasis (moniliasis). As terconazole vaginal cream is effective only for vulvovaginitis caused by the genus Candida , the diagnosis should be confirmed by KOH smears and/or cultures.

One full applicator (5 grams) of terconazole vaginal cream (40 mg terconazole) should be administered intravaginally once daily at bedtime for three consecutive days. Before prescribing another course of therapy, the diagnosis should be reconfirmed by smears and/or cultures and other pathogens commonly associated with vulvovaginitis ruled out. The therapeutic effect of terconazole vaginal cream is not affected by menstruation.

Patients known to be hypersensitive to terconazole or to any of the components of the cream.

Adverse Reactions from Clinical Trials Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. During controlled clinical studies conducted in the United States, patients with vulvovaginal candidiasis were treated with terconazole 0.8% vaginal cream for three days. Based on comparative analyses with placebo and a standard agent, the adverse experiences considered most likely related to terconazole 0.8% vaginal cream were headache (21% vs. 16% with placebo) and dysmenorrhea (6% vs. 2% with placebo). Other adverse experiences reported with terconazole 0.8% vaginal cream were abdominal pain (3.4% vs. 1% with placebo) and fever (1% vs. 0.3% with placebo). The adverse drug experience most frequently causing discontinuation of therapy was vulvovaginal itching, 0.7% with the terconazole 0.8% vaginal cream group and 0.3% with the placebo group. Post-marketing Experience The following adverse drug reactions have been first identified during post-marketing experience with terconazole:. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General: Asthenia, Influenza-Like Illness consisting of multiple listed reactions including fever and chills, nausea, vomiting, myalgia, arthralgia, malaise Immune: Hypersensitivity, Anaphylaxis, Face Edema Nervous: Dizziness Respiratory: Bronchospasm Skin: Rash, Toxic Epidermal Necrolysis, Urticaria

The therapeutic effect of terconazole is not affected by oral contraceptive usage. The levels of estradiol and progesterone did not differ significantly when 0.8% terconazole vaginal cream was administered to healthy female volunteers established on a low dose oral contraceptive.
