Warnings/Precautions

Concerns related to adverse effects:

• Irritation: Discontinue if sensitivity or irritation occurs and institute appropriate therapy.

Special populations:

• Immunocompromised patients: Use with caution; use has not been evaluated in immunosuppressed or immunocompromised patients.

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates; the "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer’s labeling.

• Nail lacquer: For topical use only; has not been studied in conjunction with systemic therapy or in patients with type 1 diabetes mellitus (insulin dependent, IDDM) or diabetic neuropathy.

• Shampoo: Patients with lighter hair color may experience hair discoloration.

Other warnings/precautions:

• Appropriate use: For topical use only; avoid contact with eyes or mucous membranes. Use of occlusive dressings or wrappings should be avoided.
