No instance of accidental ingestion of permethrin cream has been reported. If ingested, gastric lavage and general supportive measures should be employed.
Permethrin cream is contraindicated in patients with known hypersensitivity to any of its components, to any synthetic pyrethroid or pyrethrin.
In clinical trials, generally mild and transient burning and stinging followed application with permethrin cream in 10% of patients and was associated with the severity of infestation. Pruritis was reported in 7% of patients at various times post- application. Erythema, numbness, tingling, and rash were reported in 1 to 2% or less of patients (see PRECAUTIONS: General).
%medicine_name% (permethrin) Cream 5% is indicated for the treatment of infestation with Sarcoptes scabiei (scabies).
%medicine_name% (permethrin) Cream 5% (wt./ wt.) is supplied in 60g tubes.

Store at room temperature 15°- 25° C (59°- 77° F).
CAUTION: Federal (USA) law prohibits dispensing without prescription.
If hypersensitivity to permethrin cream occurs, discontinue use.
PRECAUTIONSGeneral
Scabies infestation is often accompanied by pruritis, edema and erythema. Treatment with permethrin cream may temporarily exacerbate these conditions.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Six carcinogenicity bioassays were evaluated with permethrin, three each in rats and mice. No tumorigenicity was seen in the rat studies. However, species-specific increases in pulmonary adenomas, a common benign tumor of mice of high spontaneous background incidence, were seen in the three mouse studies. In one of these studies there was an increased incidence of pulmonary alveolar- cell carcinomas and benign liver adenomas only in female mice when permethrin was given in their food at a concentration of 5000 ppm. Mutagenicity assays, which give useful correlative data for interpreting results from carcinogenicity bioassays in rodents, were negative. Permethrin showed no evidence of mutagenic potential in a battery of in vitro and in vivo genetic toxicity studies.
Permethrin did not have any adverse effect on reproductive function at a dose of 180 mg/ kg/ day orally in a three-generation rat study.
Pregnancy
Teratogenic Effects: Pregnancy Category B: Reproduction studies have been performed in mice, rats, and rabbits (200 to 400 mg/ kg/ day orally) and have revealed no evidence of impaired fertility or harm to the fetus due to permethrin. There are, however, no adequate and well- controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the evidence for tumorigenic potential of permethrin in animal studies, consideration should be given to discontinuing nursing temporarily or withholding the drug while the mother is nursing.
Pediatric Use
Permethrin cream is safe and effective in pediatric patients two months of age and older. Safety and effectiveness in pediatric patients less than two months of age have not been established.
Geriatric Use
Clinical studies of permethrin cream did not identify sufficient numbers of subjects aged 65 and over to allow a definitive statement regarding whether elderly subjects respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. This drug is known to be substantially excreted by the kidney. However, since topical permethrin is metabolized in the liver and excreted in the urine as inactive metabolites, there does not appear to be an increased risk of toxic reactions in patients with impaired renal function when used as labeled.
Adults and children: Thoroughly massage %medicine_name% (permethrin) Cream into the skin from the head to the soles of the feet. Scabies rarely infests the scalp of adults, although the hairline, neck, temple, and forehead may be infested in infants and geriatric patients. Usually 30 grams is sufficient for an average adult. The cream should be removed by washing (shower or bath) after 6 to 14 hours. Infants should be treated on the scalp, temple and forehead.
ONE APPLICATION IS GENERALLY CURATIVE.
Patients may experience persistent pruritus after treatment. This is rarely a sign of treatment failure and is not an indication for retreatment. Demonstrable living mites after 14 days indicate that retreatment is necessary.
In clinical trials, generally mild and transient burning and stinging followed application with permethrin cream in 10% of patients and was associated with the severity of infestation. Pruritis was reported in 7% of patients at various times post- application. Erythema, numbness, tingling, and rash were reported in 1 to 2% or less of patients (see PRECAUTIONS: General).
