Concerns related to adverse effects:

• Irritation: Discontinue if sensitivity or irritation occurs.

Special populations:

• Immunocompromised patients: 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 and has not been studied in conjunction with systemic therapy or in patients with type 1 diabetes mellitus (insulin dependent, IDDM).

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.

Pregnancy Risk Factor


Pregnancy Considerations

Teratogenic effects were not observed in animal studies, however, there are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if clearly needed.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience hair discoloration or skin or nail changes. Have patient report immediately to prescriber edema, skin sores, oozing, hemorrhaging, severe skin irritation, or significant scalp irritation (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
