5 WARNINGS AND PRECAUTIONS 5.1 Local Adverse Reactions If irritation develops, discontinue treatment and institute appropriate therapy. Physicians should exercise caution when prescribing ERTACZO cream, 2%, to patients known to be sensitive to azole antifungals since cross-reactivity may occur.
6 ADVERSE REACTIONS Most common adverse reactions observed in clinical trials (incidence >2%) were contact dermatitis, dry skin, burning skin, application site skin tenderness. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bausch Health US, LLC at 1-800-321-4576 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 practice. In clinical trials, cutaneous adverse events occurred in 7 of 297 (2%) subjects (2 of them severe) receiving ERTACZO cream, 2%, and in 7 of 291 (2%) subjects (2 of them severe) receiving vehicle. These reported cutaneous adverse events included contact dermatitis, dry skin, burning skin, and application site skin tenderness. In a dermal sensitization trial, 8 of 202 evaluable subjects tested with ERTACZO cream, 2%, and 4 of 202 evaluable subjects tested with vehicle exhibited a erythematous reaction in the challenge phase. There was no evidence of cumulative irritation or contact sensitization in a repeated insult patch test involving 202 healthy volunteers. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of ERTACZO cream, 2%. 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. Cutaneous adverse events: erythema, pruritus, vesiculation, desquamation, and hyperpigmentation.
