|Hair Length||Amount of
|Ounces||8 oz bottle Size|
|Short||0-2 inches||4-6 oz||½-¾ bottle|
|2-4 inches||6-8 oz||¾-1 bottle|
|Medium||4-8 inches||8-12 oz||1-1½ bottles|
|8-16 inches||12-24 oz||1½-3 bottles|

|Over 22 inches||32-48 oz||4-6 bottles|
ULESFIA® Lotion is a white topical lotion containing benzyl alcohol, 5% (50 mg/g of lotion).
Intravenous administration of products containing benzyl alcohol has been associated with neonatal gasping syndrome consisting of severe metabolic acidosis, gasping respirations, progressive hypotension, seizures, central nervous system depression, intraventricular hemorrhage, and death in preterm, low birth weight infants. Neonates (i.e. patients less than 1 month of age or preterm infants with a corrected age of less than 44 weeks) could be at risk for gasping syndrome if treated with ULESFIA® Lotion [see Use in Specific Populations (8.4)].
Avoid eye exposure. ULESFIA® Lotion may cause eye irritation. If ULESFIA® Lotion comes in contact with the eyes, flush them immediately with water. If irritation persists, consult a physician.
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 clinical practice.
The rates of adverse reactions below were derived from two randomized, multi-center, vehicle-controlled clinical trials and one open-label study in subjects with head lice infestation.
Skin, scalp, and ocular irritation were monitored in the clinical trials. All subjects were queried about the presence of skin and scalp symptoms; the results are presented in Table 2.
|Application site |
|2% (11/478)||1% (2/336)|
|Application site |
|2% (10/478)||0% (0/336)|
|Pain||1% (5/478)||0% (1/336)|
The subset of subjects who did not have pruritus, erythema, edema or pyoderma of skin and scalp, or ocular irritation prior to treatment were assessed for these signs and symptoms after treatment; the results are presented in Table 3.
|Pruritus||12% (14/116)||4% (3/67)|
|Erythema||10% (32/309)||9% (19/217)|
|Pyoderma||7% (22/308)||4% (10/230)|
|Ocular irritation||6% (26/428)||1% (3/313)|
Other less common reactions (less than 1% but more than 0.1%) were, in decreasing order of incidence: application site dryness, application site excoriation, paraesthesia, application site dermatitis, excoriation, thermal burn, dandruff, erythema, rash, and skin exfoliation.
Pregnancy Category B
There are no adequate and well-controlled studies with topical benzyl alcohol in pregnant women. Reproduction studies conducted in rats and rabbits were negative. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
No comparisons of animal exposure with human exposure are provided in this labeling due to the low systemic exposure noted in the clinical pharmacokinetic study [see Clinical Pharmacology (12.3)] which did not allow for the determination of human AUC values that could be used for this calculation.
Pregnant rats were dosed with benzyl alcohol via subcutaneous injection at 100, 250, and 500 mg/kg/day. No teratogenic effects were noted at any dose. Maternal toxicity and decreased fetal weight occurred at 500 mg/kg/day. When pregnant rabbits received subcutaneous injections of benzyl alcohol at 100, 250, and 400 mg/kg/day, there were no teratogenic effects in offspring at any dose. In rabbits, maternal toxicity occurred at the two higher doses and was associated with decreased fetal weight at the highest dose.
It is not known whether benzyl alcohol is excreted into human milk. Because some systemic absorption of topical benzyl alcohol may occur and because many drugs are excreted in human milk, caution should be exercised when ULESFIA® Lotion is administered to a nursing woman.
The safety and effectiveness of ULESFIA® Lotion was evaluated in two multicenter, randomized, double-blind, vehicle-controlled studies which were conducted in 628 subjects 6 months of age and older with active head lice infestation [see Clinical Studies (14)].
Rates of adverse events in younger children (6 months to 12 years) were similar to those of older children and adults.
Safety in pediatric patients below the age of 6 months has not been established. ULESFIA® Lotion is not recommended in pediatric patients under six months of age because of the potential for increased systemic absorption due to a high ratio of skin surface area to body mass and the potential for an immature skin barrier.
Intravenous administration of products containing benzyl alcohol has been associated with neonatal gasping syndrome. The gasping syndrome (characterized by central nervous depression, metabolic acidosis, gasping respirations, and high levels of benzyl alcohol and its metabolites found in the blood and urine) has been associated with benzyl alcohol dosages > 99 mg/kg/day in preterm neonates. Additional symptoms may include gradual neurological deterioration, seizures, intracranial hemorrhage, hemotologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Although expected systemic exposure of benzyl alcohol from proper use of ULESFIA® Lotion is substantially lower than those reported in association with the gasping syndrome, the minimum amount of benzyl alcohol at which toxicity may occur is not known.
ULESFIA® (benzyl alcohol) Lotion is supplied as a white topical lotion containing benzyl alcohol, 5%. Inactive ingredients in this formulation are water, mineral oil, sorbitan monooleate, polysorbate 80, carbomer 934P and trolamine.
The active ingredient, benzyl alcohol, is a clear, colorless liquid with a mild aromatic odor. Benzyl alcohol has a molecular mass of 108.14 g/mol. The molecular formula is C7H8O.
The chemical structure of benzyl alcohol is:
In vitro studies of the effect of ULESFIA® Lotion on native, captured lice suggest that benzyl alcohol inhibits lice from closing their respiratory spiracles, allowing the vehicle to obstruct the spiracles and causing the lice to asphyxiate.
The absorption of benzyl alcohol from ULESFIA® Lotion was evaluated in 19 subjects with head lice infestation. Subjects were divided into two age groups: 6 months to 3 years and 4 to 11 years. ULESFIA® Lotion was applied for an exaggerated exposure period (3 times the normal exposure period). Benzyl alcohol was quantified in a single plasma sample in 4 out of 19 subjects (21%): three subjects in the 6 months to 3 years age group at 0.5 hour post-treatment (ranging from 1.97 to 2.99 mcg/mL) and one subject in the 4 to 11 year age group (1.63 mcg/mL) at 1 hour post-treatment out of a total of 102 samples analyzed.
Long-term studies in animals to evaluate carcinogenic potential of ULESFIA® Lotion have not been conducted. No evidence of carcinogenic activity was noted for benzyl alcohol in 2 year oral carcinogenicity studies in rats (doses up to 400 mg/kg benzyl alcohol) or mice (doses up to 200 mg/kg benzyl alcohol) conducted by the National Toxicology Program.
Benzyl alcohol has produced mixed results in genetic testing. Benzyl alcohol was negative in the Ames test with and without metabolic activation, sex-linked recessive lethal assay, and a replicative DNA synthesis assay (conducted in male rats). Negative results were obtained in the mouse lymphoma assay with metabolic activation, but a positive response was noted in the mouse lymphoma assay without metabolic activation at a concentration producing a high level of cellular toxicity. Benzyl alcohol was positive in the Chinese hamster ovary chromosomal aberration assay with metabolic activation.
No fertility studies have been conducted with benzyl alcohol.
Two multicenter, randomized, double-blind, vehicle-controlled studies were conducted in 628 subjects 6 months of age and older with active head lice infestation. For the evaluation of efficacy, the youngest subject from each household was enrolled in the Primary Treatment Cohort with ULESFIA® Lotion or vehicle. Other infested household members were enrolled in a Secondary Treatment Cohort and received the same treatment as the youngest subjects. The Secondary Treatment Cohort was not included in the efficacy analysis, but was evaluated for all safety parameters.
In Study One, 125 Primary Treatment Cohort Subjects were randomized to ULESFIA® Lotion (N=63) and vehicle (N=62). Study Two enrolled 125 Primary Treatment Cohort Subjects: 64 randomized to ULESFIA® Lotion and 61 to vehicle. Treatment was applied two times separated by one week.
Efficacy was assessed as the proportion of subjects who were free of live lice 14 days after the final treatment. Subjects with live lice present at any time after first treatment were considered to be treatment failures. Table 4 contains the proportion of subjects who were free of live lice in each of the two trials.

Instructions for Use
Apply the full amount ofULESFIA® Lotion prescribed by your healthcare provider for each of your 2 applications one week apart. ULESFIA® Lotion gets rid of lice but does not get rid of lice eggs so a second application is needed one week (7 days) after the first application.
ULESFIA® Lotion comes in a single 8 oz. bottle, and in a 2 pack containing two 8 oz. bottles with a lice comb. For different hair lengths, use the following as a guide for the amount of ULESFIA® Lotion you may need to cover the hair and scalp completely:
|Hair Length||Amount of ULESFIA® Lotion to apply each time|
|8 oz. bottle|
|Short- up to 2 inches||up to ¾ the bottle|
|Short- 2-4 inches||up to 1 bottle|
|Medium- 4-8 inches||up to 1½ bottles|
|Medium- 8-16 inches||up to 3 bottles|
|Long- 16-22 inches||up to 4 bottles|
|Long- 22 inches or more||up to 6 bottles|
If not enough ULESFIA® Lotion is used, some lice may escape treatment. It is important to use the full amount of ULESFIA® Lotion prescribed by your healthcare provider.
Correct application of ULESFIA® Lotion.
One week (7 days) after your first application, repeat the steps above to help get rid of lice that hatched from eggs.
