For topical use only; not for oral, ophthalmic, or intravaginal use. Apply once daily for 4 weeks.

Clinical Trials Experience

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 practice. In two double-blind, vehicle-controlled clinical trials, 495 subjects were exposed to Ecoza topical foam or vehicle (246 subjects were exposed to Ecoza topical foam, 1% and 249 were exposed to vehicle). Subjects with interdigital tinea pedis applied foam or vehicle once daily for approximately 28 days. During clinical trials with Ecoza topical foam, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the Ecoza and vehicle arms.

Warfarin

Concomitant administration of econazole and warfarin has resulted in enhancement of anticoagulant effect. Most cases reported product application with use under occlusion, genital application, or application to a large body surface area which may increase the systemic absorption of econazole nitrate. Monitoring of International Normalized Ratio (INR) and/or prothrombin time may be indicated especially for patients who apply econazole to large body surface areas, in the genital area, or under occlusion.

Pregnancy Pregnancy Category C There are no adequate and well-controlled trials with Ecoza topical foam in pregnant women. Ecoza topical foam should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Econazole nitrate has not been shown to be teratogenic when administered orally to mice, rabbits or rats.

Fetotoxic or embryotoxic effects were observed in Segment I oral studies with rats receiving 10 to 40 times the human dermal dose. Similar effects were observed in Segment II or Segment III studies with mice, rabbits and/or rats receiving oral doses 80 or 40 times the human dermal dose.

Pediatric Use Of the 173 subjects treated with Ecoza topical foam, 1% in the clinical trials, 2 subjects were 12 to 17 years old. In a pediatric maximal use trial, Ecoza topical foam, 1% was applied once daily to eighteen subjects aged 12 to 17 years with interdigital tinea pedis for 28 days. The safety findings for subjects 12 to 17 years were similar to those in adult population.
