Children
Use under direct adult supervision. Keep out of children’s reach. Lotion for the treatment of head lice is not recommended for infants • Neonates: Intravenous administration of benzyl alcohol–containing products has been associated with a neonatal gasping syndrome. Patients Dosage form specific issues:
Benzyl alcohol and derivatives
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. Other warnings/precautions:
Self-medication (OTC use)
Discontinue use and notify health care provider if condition worsens or does not improve within 7 days, or if swelling, rash, or fever develops. Do not use for >7 days unless instructed by health care professional.
Pregnancy & Lactation
Pregnancy
Adverse events have not been observed in animal reproduction studies.
Lactation
It is unknown if benzyl alcohol is excreted in breast milk. The manufacturer recommends that caution be exercised when administering benzyl alcohol to nursing women.
