BACTROBAN NASAL is indicated for the eradication of nasal colonization with methicillin-resistant S. aureus in adult patients and health care workers as part of a comprehensive infection control program to reduce the risk of infection among patients at high risk of methicillin-resistant S. aureus infection during institutional outbreaks of infections with this pathogen. NOTE: There are insufficient data at this time to establish that this product is safe and effective as part of an intervention program to prevent autoinfection of high-risk patients from their own nasal colonization with S. aureus . There are insufficient data at this time to recommend use of BACTROBAN NASAL for general prophylaxis of any infection in any patient population. Greater than 90% of subjects/patients in clinical trials had eradication of nasal colonization 2 to 4 days after therapy was completed. Approximately 30% recolonization was reported in 1 domestic study within 4 weeks after completion of therapy. These eradication rates were clinically and statistically superior to those reported in subjects/patients in the vehicle-treated arms of the adequate and well-controlled studies. Those treated with vehicle had eradication rates of 5% to 30% at 2 to 4 days post-therapy with 85% to 100% recolonization within 4 weeks. All adequate and well-controlled trials of this product were vehicle-controlled; therefore, no data from direct, head-to-head comparisons with other products are available at this time.
(See INDICATIONS AND USAGE.) Adults (12 years of age and older): Approximately one-half of the ointment from the single-use tube should be applied into 1 nostril and the other half into the other nostril twice daily (morning and evening) for 5 days. After application, the nostrils should be closed by pressing together and releasing the sides of the nose repetitively for approximately 1 minute. This will spread the ointment throughout the nares. The single-use 1.0 gram tube will deliver a total of approximately 0.5 grams of the ointment (approximately 0.25 grams/nostril). The tube should be discarded after usage; it should not be re-used. The safety and effectiveness of applications of this medication for greater than 5 days have not been established. There are no human clinical or pre-clinical animal data to support the use of this product in a chronic manner or in manners other than those described in this package insert. Until further information is known, BACTROBAN NASAL should not be applied concurrently with any other intranasal products.
BACTROBAN NASAL is contraindicated in patients with known hypersensitivity to any of the constituents of the product.
Clinical Trials In clinical trials, 210 domestic and 2,130 foreign adult subjects/patients received BACTROBAN NASAL ointment. Less than 1% of domestic or foreign subjects and patients in clinical trials were withdrawn due to adverse events. The most frequently reported adverse events in foreign clinical trials were as follows: Rhinitis (1.0%), taste perversion (0.8%), pharyngitis (0.5%). In domestic clinical trials, 17% (36/210) of adults treated with BACTROBAN NASAL ointment reported adverse events thought to be at least possibly drug-related. The incidence of adverse events that were reported in at least 1% of adults enrolled in domestic clinical trials were as follows: ADVERSE EVENTS (?1% INCIDENCE)-ADULTS IN US TRIALS % of Subjects/Patients Experiencing Event BACTROBAN NASAL (n=210) Headache 9% Rhinitis 6% Respiratory disorder, including upper respiratory tract congestion 5% Pharyngitis 4% Taste perversion 3% Burning/stinging 2% Cough 2% Pruritus 1% The following events thought possibly drug-related were reported in less than 1% of adults enrolled in domestic clinical trials: Blepharitis, diarrhea, dry mouth, ear pain, epistaxis, nausea, and rash. All adequate and well-controlled clinical trials have been performed using BACTROBAN NASAL ointment, 2% in 1 arm and the vehicle ointment in the other arm of the study. No adequate and well-controlled safety data are available from direct, head-to-head comparative studies of this product and other products for this indication.
AVOID CONTACT WITH THE EYES. Application of BACTROBAN NASAL to the eye under testing conditions has caused severe symptoms such as burning and tearing. These symptoms resolved within days to weeks after discontinuation of the ointment. In the event of a sensitization or severe local irritation from BACTROBAN NASAL, usage should be discontinued.
The effect of the concurrent application of intranasal mupirocin calcium and other intranasal products has not been studied. Until further information is known, mupirocin calcium ointment, 2% should not be applied concurrently with any other intranasal products.
