BACTROBAN cream is contraindicated in patients with known hypersensitivity to mupirocin or any of the excipients of BACTROBAN cream.
The following adverse reactions are discussed in more detail in other sections of the labeling:
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In 2 randomized, double-blind, double-dummy trials, 339 subjects were treated with topical BACTROBAN cream plus oral placebo. Adverse reactions occurred in 28 (8.3%) subjects. The following adverse reactions were reported by at least 1% of subjects in connection with the use of BACTROBAN cream in clinical trials: headache (1.7%), rash (1.1%), and nausea (1.1%).
Other adverse reactions which occurred in less than 1% of subjects were: abdominal pain, burning at application site, cellulitis, dermatitis, dizziness, pruritus, secondary wound infection, and ulcerative stomatitis.
In a supportive trial in the treatment of secondarily infected eczema, 82 subjects were treated with BACTROBAN cream. The incidence of adverse reactions was as follows: nausea (4.9%), headache and burning at application site (3.6% each), pruritus (2.4%), and 1 report each of abdominal pain, bleeding secondary to eczema, pain secondary to eczema, hives, dry skin, and rash.
Postmarketing ExperienceIn addition to adverse reactions reported from clinical trials, the following reactions have been identified during postmarketing use of BACTROBAN cream. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These reactions have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal relationship to BACTROBAN cream.
Immune System DisordersSystemic allergic reactions, including anaphylaxis, urticaria, angioedema, and generalized rash.
BACTROBAN® cream is indicated for the treatment of secondarily infected traumatic skin lesions (up to 10 cm in length or 100 cm² in area) due to susceptible isolates of Staphylococcus aureus (S. aureus) and Streptococcus pyogenes (S. pyogenes).
Systemic absorption of mupirocin through intact human skin is minimal. The systemic absorption of mupirocin was studied following application of BACTROBAN cream 3 times daily for 5 days to various skin lesions greater than 10 cm in length or 100 cm² in area in 16 adults (aged 29 to 60 years) and 10 children (aged 3 to 12 years). Some systemic absorption was observed as evidenced by the detection of the metabolite, monic acid, in urine. Data from this trial indicated more frequent occurrence of percutaneous absorption in children (90% of subjects) compared with adults (44% of subjects); however, the observed urinary concentrations in children (0.07 to 1.3 mcg per mL [1 pediatric subject had no detectable level]) are within the observed range (0.08 to 10.03 mcg per mL [9 adults had no detectable level]) in the adult population. In general, the degree of percutaneous absorption following multiple dosing appears to be minimal in adults and children.
The effect of the concurrent application of BACTROBAN cream with other topical products has not been studied.
EliminationIn a trial conducted in 7 healthy adult male subjects, the elimination half-life after intravenous administration of mupirocin was 20 to 40 minutes for mupirocin and 30 to 80 minutes for monic acid.
Metabolism: Following intravenous or oral administration, mupirocin is rapidly metabolized. The principal metabolite, monic acid, demonstrates no antibacterial activity.
Excretion: Monic acid is predominantly eliminated by renal excretion.
There are no adequate and well-controlled studies of BACTROBAN cream (contains equivalent of 2% mupirocin free acid) 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.
Developmental toxicity studies have been performed with mupirocin administered subcutaneously to rats and rabbits at doses up to 160 mg per kg per day in both species. This dose is 22 and 43 times, respectively, the human topical dose (approximately 60 mg mupirocin per day) based on body surface area. There was no evidence of fetal harm due to mupirocin.

Included as part of the PRECAUTIONS section.
PRECAUTIONS Severe Allergic ReactionsSystemic allergic reactions, including anaphylaxis, urticaria, angioedema, and generalized rash, have been reported in patients treated with formulations of BACTROBAN, including BACTROBAN cream.
Eye IrritationAvoid contact with the eyes. In case of accidental contact, rinse well with water.
Local IrritationIn the event of a sensitization or severe local irritation from BACTROBAN cream, usage should be discontinued, and appropriate alternative therapy for the infection instituted.
Clostridium Difficile-Associated DiarrheaClostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over 2 months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
Potential For Microbial OvergrowthAs with other antibacterial products, prolonged use of BACTROBAN cream may result in overgrowth of nonsusceptible microorganisms, including fungi.
Risk Associated With Mucosal UseBACTROBAN cream is not formulated for use on mucosal surfaces. A separate formulation, BACTROBAN® (mupirocin calcium) nasal ointment, is available for intranasal use.
Patient Counseling InformationAdvise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).
Advise the patient to administer BACTROBAN cream as follows:
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 genotoxicity: 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.
Reproduction studies were performed with mupirocin administered subcutaneously to male and female rats at doses up to 100 mg per kg per day which is 14 times the human topical dose (approximately 60 mg mupirocin per day) based on body surface area. Neither evidence of impaired fertility nor impaired reproductive performance attributable to mupirocin was observed.
Use In Specific Populations Pregnancy Pregnancy Category BThere are no adequate and well-controlled studies of BACTROBAN cream (contains equivalent of 2% mupirocin free acid) 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.
Developmental toxicity studies have been performed with mupirocin administered subcutaneously to rats and rabbits at doses up to 160 mg per kg per day in both species. This dose is 22 and 43 times, respectively, the human topical dose (approximately 60 mg mupirocin per day) based on body surface area. There was no evidence of fetal harm due to mupirocin.
Nursing MothersIt 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 UseThe 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 trials of BACTROBAN cream in adults with additional data from 93 pediatric subjects studied as part of the pivotal trials in adults.
Geriatric UseIn 2 adequate and well-controlled trials, 30 subjects 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 with that observed in younger patients.
