( 5.1 ) 5.1 Local Adverse Reactions Discontinue treatment if irritation or sensitivity develops with the use of Naftifine Hydrochloride Cream. Direct patients to contact their physician if these conditions develop following use of Naftifine Hydrochloride Cream.

6 ADVERSE REACTIONS The most common adverse reaction (≥1%) is pruritus. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries, Inc., at 1-866-923-4914 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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 clinical practice. During clinical trials, 903 subjects were exposed to naftifine 1% and 2% cream formulations. A total of 564 subjects with interdigital tinea pedis, tinea cruris, or tinea corporis were treated with Naftifine Hydrochloride Cream. In two randomized, vehicle-controlled trials (400 subjects were treated with Naftifine Hydrochloride Cream). The population was 12 to 88 years old, primarily male (79%), 48% Caucasian, 36% Black or African American, 40% Hispanic or Latino and had either predominantly interdigital tinea pedis or tinea cruris. Most subjects received doses once-daily, topically, for 2 weeks to cover the affected skin areas plus a ½ inch margin of surrounding healthy skin. In the two vehicle-controlled trials, 17.5% of Naftifine Hydrochloride Cream treated subjects experienced an adverse reaction compared with 19.3% of vehicle subjects. The most common adverse reaction (≥1%) is pruritus. Most adverse reactions were mild in severity. The incidence of adverse reactions in the Naftifine Hydrochloride Cream treated population was not significantly different than in the vehicle treated population. In a third randomized, vehicle-controlled trial, 116 pediatric subjects with tinea corporis were treated with Naftifine Hydrochloride Cream. The population was aged ≥2 to <18 years (mean age of 9 years), predominately male (61%), 47% White, 51% Black or African American, 92% Hispanic or Latino, and infected with tinea corporis. Naftifine Hydrochloride Cream was topically applied once daily for 2 weeks to all affected body surface areas with tinea corporis plus a ½ inch margin of healthy skin surrounding the affected lesions. The incidence of adverse reactions in the Naftifine Hydrochloride Cream treated population was not significantly different than in the vehicle treated population. In two open-label pediatric pharmacokinetics and safety trials, 49 pediatric subjects 2 to <18 years of age with interdigital tinea pedis, tinea cruris, and tinea corporis received Naftifine Hydrochloride Cream. The incidence of adverse reactions in the pediatric population was similar to that observed in the adult population. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of naftifine hydrochloride: redness/irritation, inflammation, maceration, swelling, burning, blisters, serous drainage, crusting, headache, dizziness, leukopenia, agranulocytosis. 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.
