WARNINGS
Avoid contact with the eyes.
In the event of a sensitization or severe local irritation from BACTROBAN CREAM, usage should be discontinued, and appropriate alternative therapy for the infection instituted.
PRECAUTIONS
General
As with other antibacterial products, prolonged use may result in overgrowth of nonsusceptible microorganisms, including fungi. (See Dosage And Administration.)
BACTROBAN CREAM is not formulated for use on mucosal surfaces.
Information for Patients
• Use this medication only as directed by your healthcare provider. It is for external use only. Avoid contact with the eyes.
• The treated area may be covered by gauze dressing if desired.
• Report to your healthcare provider any signs of local adverse reactions. The medication should be stopped and your healthcare provider contacted if irritation, severe itching, or rash occurs.
• If no improvement is seen in 3 to 5 days, contact your healthcare provider.
Drug Interactions
The effect of the concurrent application of topical mupirocin calcium cream and other topical products has not been studied.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies in animals to evaluate carcinogenic potential of mupirocin calcium have not been conducted.
Results of the following studies performed with mupirocin calcium or mupirocin sodium in vitro and in vivo did not indicate a potential for mutagenicity: Rat primary hepatocyte unscheduled DNA synthesis, sediment analysis for DNA strand breaks, Salmonella reversion test (Ames), Escherichia coli mutation assay, metaphase analysis of human lymphocytes, mouse lymphoma assay, and bone marrow micronuclei assay in mice.
Fertility studies were performed in rats with mupirocin administered subcutaneously at doses up to 49 times a human topical dose of 1 gram/day (approximately 20 mg mupirocin per day) on a mg/m2 basis and revealed no evidence of impaired fertility from mupirocin sodium.
Pregnancy
Teratogenic Effects
Pregnancy Category B. Teratology studies have been performed in rats and rabbits with mupirocin administered subcutaneously at doses up to 78 and 154 times, respectively, a human topical dose of 1 gram/day (approximately 20 mg mupirocin per day) on a mg/m2 basis and revealed no evidence of harm to the fetus due to mupirocin. 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, caution should be exercised when BACTROBAN CREAM is administered to a nursing woman.
Pediatric Use
The safety and effectiveness of BACTROBAN CREAM have been established in the age groups 3 months to 16 years. Use of BACTROBAN CREAM in these age groups is supported by evidence from adequate and well-controlled studies of BACTROBAN CREAM in adults with additional data from 93 pediatric patients studied as part of the pivotal trials in adults. (See CLINICAL STUDIES.)
Geriatric Use
In 2 well-controlled studies, 30 patients older than 65 years were treated with BACTROBAN CREAM. No overall difference in the efficacy or safety of BACTROBAN CREAM was observed in this patient population when compared to that observed in younger patients.[1]
