6 ADVERSE REACTIONS The most common adverse reactions (incidence >1%) were ingrown toenails, application site dermatitis, application site vesicles, and application site pain.

In two clinical trials, 1227 subjects were treated with JUBLIA, 1161 for at least 24 weeks and 780 for 48 weeks. Adverse reactions reported within 48 weeks of treatment and in at least 1% of subjects treated with JUBLIA and those reported in subjects treated with the vehicle are presented in Table 1 . Table 1: Adverse Reactions Reported by at Least 1% of Subjects Treated for up to 48 Weeks Adverse Event, n (%) JUBLIA (N=1,227) Vehicle (N=413) Ingrown toenail 28 (2.3%) 3 (0.7%) Application site dermatitis 27 (2.2%) 1 (0.2%) Application site vesicles 20 (1.6%) 0 (0.0%) Application site pain 13 (1.1%) 1 (0.2%) 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of JUBLIA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure. General Disorders and Administration Site Conditions: Application site erythema and exfoliation Skin and Subcutaneous Tissue Disorders: Onychomadesis, Nail discoloration

7 DRUG INTERACTIONS In vitro studies have shown that JUBLIA, at therapeutic concentrations, neither inhibits nor induces cytochrome P450 (CYP450) enzymes.
