CEFOTAN (Injection, Solution)
|
| dailymed-instance:dosage |
Treatment:<br/>Cefotetan injection in Galaxy plastic container should not be used for intramuscular administration.: CEFOTAN in the ADD-Vantage Vial is intended for intravenous infusion only, after dilution with the appropriate volume of ADD-Vantage diluent solution. The usual adult dosage is 1 or 2 grams of CEFOTAN (cefotetan disodium for injection) administered intravenously or intramuscularly or CEFOTAN (cefotetan injection) in the Galaxy plastic container (PL 2040) administered intravenously every 12 hours for 5 to 10 days. Proper dosage and route of administration should be determined by the condition of the patient, severity of the infection, and susceptibility of the causative organism. If Chlamydia trachomatis is a suspected pathogen in gynecologic infections, appropriate antichlamydial coverage should be added, since cefotetan has no activity against this organism.<br/>Prophylaxis:: To prevent postoperative infection in clean contaminated or potentially contaminated surgery in adults, the recommended dosage is 1 or 2 g of CEFOTAN administered once, intravenously, 30 to 60 minutes prior to surgery. In patients undergoing cesarean section, the dose should be administered as soon as the umbilical cord is clamped.<br/>Impaired Renal Function: When renal function is impaired, a reduced dosage schedule must be employed. The following dosage guidelines may be used. Alternatively, the dosing interval may remain constant at 12 hour intervals, but the dose reduced to one-half the usual recommended dose for patients with a creatinine clearance of 10-30 mL/min, and one-quarter the usual recommended dose for patients with a creatinine clearance of less than 10 mL/min. When only serum creatinine levels are available, creatinine clearance may be calculated from the following formula. The serum creatinine level should represent a steady state of renal function. Males:Weight (kg) x (140 - age) 72 x serum creatinine (mg/100 mL) Females:0.9 x value for males Cefotetan is dialyzable and it is recommended that for patients undergoing intermittent hemodialysis, one-quarter of the usual recommended dose be given every 24 hours on days between dialysis and one-half the usual recommended dose on the day of dialysis.

CEFOTAN (cefotetan disodium for injection) and CEFOTAN (cefotetan injection) in Galaxy * plastic container (PL 2040) as cefotetan disodium are sterile, semisynthetic, broad-spectrum, beta-lactamase resistant, cephalosporin (cephamycin) antibiotics for parenteral administration. It is the disodium salt of [6R-(6��,7��)]-7-[[[4-(2-amino-1-carboxy-2-oxoethylidene)-1,3-dithietan-2-yl]carbonyl]amino]-7-methoxy-3-[[(1-methyl-1H-tetrazol-5-yl)thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid. Its molecular formula is CHNNaOSwith a molecular weight of 619.57.<br/>Structural Formula: CEFOTAN (cefotetan disodium for injection) is supplied in vials containing 80 mg (3.5 mEq) of sodium per gram of cefotetan activity. It is a white to pale yellow powder which is very soluble in water. Reconstituted solutions of CEFOTAN (cefotetan disodium for injection) are intended for intravenous and intramuscular administration. The solution varies from colorless to yellow depending on the concentration. The pH of freshly reconstituted solutions is usually between 4.5 to 6.5. CEFOTAN in the ADD-Vantage Vial���is intended for intravenous use only after dilution with the appropriate volume of ADD-Vantage diluent solution. CEFOTAN is available in two vial strengths. Each CEFOTAN 1 g vial contains cefotetan disodium equivalent to 1 g cefotetan activity. Each CEFOTAN 2 g vial contains cefotetan disodium equivalent to 2 g cefotetan activity. CEFOTAN (cefotetan injection) in the Galaxy plastic container (PL 2040) is a frozen, iso-osmotic, sterile, nonpyrogenic premixed 50 mL solution containing 1 g or 2 g cefotetan as sterile cefotetan disodium. Dextrose, USP has been added to adjust the osmolality to 300 mOsmol/kg (approximately 1.9 g and 1.1 g to the 1 g and 2 g dosages, respectively); sodium bicarbonate has been added to convert cefotetan free acid to the sodium salt. The pH has been adjusted between 4 and 6.5 with sodium bicarbonate and may have been adjusted with hydrochloric acid. CEFOTAN (cefotetan injection) in the Galaxy plastic container (PL 2040) contains 80 mg (3.5 mEq) of sodium per gram of cefotetan activity. After thawing to room temperature, the solution is intended for intravenous use only. This Galaxy container is fabricated from a specially designed multilayer plastic (PL 2040). Solutions are in contact with the polyethylene layer of this container and can leach out certain chemical components of the plastic in very small amounts within the expiration dating period. The suitability of the plastic has been confirmed in tests in animals according to the USP biological tests for plastic containers as well as by tissue culture toxicity.

High plasma levels of cefotetan are attained after intravenous and intramuscular administration of single doses to normal volunteers. The plasma elimination half-life of cefotetan is 3 to 4.6 hours after either intravenous or intramuscular administration. Repeated administration of CEFOTAN does not result in accumulation of the drug in normal subjects. Cefotetan is 88% plasma protein bound. No active metabolites of cefotetan have been detected; however, small amounts (less than 7%) of cefotetan in plasma and urine may be converted to its tautomer, which has antimicrobial activity similar to the parent drug. In normal patients, from 51% to 81% of an administered dose of CEFOTAN is excreted unchanged by the kidneys over a 24 hour period, which results in high and prolonged urinary concentrations. Following intravenous doses of 1 gram and 2 grams, urinary concentrations are highest during the first hour and reach concentrations of approximately 1700 and 3500��g/mL respectively. In volunteers with reduced renal function, the plasma half-life of cefotetan is prolonged. The mean terminal half-life increases with declining renal function, from approximately 4 hours in volunteers with normal renal function to about 10 hours in those with moderate renal impairment. There is a linear correlation between the systemic clearance of cefotetan and creatinine clearance. When renal function is impaired, a reduced dosing schedule based on creatinine clearance must be used. . In pharmacokinetics studies of eight elderly patients (greater than 65 years) with normal renal function and six healthy volunteers (aged 25 to 28 years), mean (��1sd) Total Body Clearance (1.8(0.1) L/h vs. 1.8 (0.3) L/h) and mean Volume of Distribution (10.4(1.2) L vs. 10.3 (1.6)L) were similar following administration of a one gram intravenous bolus dose. Therapeutic levels of cefotetan are achieved in many body tissues and fluids including:<br/>Microbiology: The bactericidal action of cefotetan results from inhibition of cell wall synthesis. Cefotetan has in vitro activity against a wide range of aerobic and anaerobic gram-positive and gram-negative organisms. The methoxy group in the 7-alpha position provides cefotetan with a high degree of stability in the presence of beta-lactamases including both penicillinases and cephalosporinases of gram-negative bacteria. Cefotetan has been shown to be active against most strains of the following organisms both in vitro and in clinical infections .<br/>Gram-Negative Aerobes: Escherichia coli Haemophilus influenzae (including ampicillin-resistant strains) Klebsiella species (including K. pneumoniae) Morganella morganii Neisseria gonorrhoeae (nonpenicillinase-producing strains) Proteus mirabilis Proteus vulgaris Providencia rettgeri Serratia marcescens NOTE: Approximately one-half of the usually clinically significant strains of Enterobacter species (eg, E. aerogenes and E. cloacae) are resistant to cefotetan. Most strains of Pseudomonas aeruginosa and Acinetobacter species are resistant to cefotetan.<br/>Gram-Positive Aerobes: Staphylococcus aureus (including penicillinase- and nonpenicillinase-producing strains) Staphylococcus epidermidis Streptococcus agalactiae (group B beta-hemolytic streptococcus) Streptococcus pneumoniae Streptococcus pyogenes NOTE: Methicillin-resistant staphylococci are resistant to cephalosporins. Some strains of Staphylococcus epidermidis and most strains of enterococci, eg, Enterococcus faecalis (formerly Streptococcus faecalis) are resistant to cefotetan<br/>Anaerobes: Prevotella bivia (formerly Bacteroides bivius) Prevotella disiens (formerly Bacteroides disiens) Bacteroides fragilis Prevotella melaninogenica (formerly Bacteroides melaninogenicus) Bacteroides vulgatus Fusobacterium species Gram-positive bacilli NOTE: Most strains of C. difficile are resistant . Peptococcus niger Peptostreptococcus species NOTE: Many strains of B. distasonis, B. ovatus and B. thetaiotaomicron are resistant to cefotetan in vitro. However, the therapeutic utility of cefotetan against these organisms cannot be accurately predicted on the basis of in vitro susceptibility tests alone. The following in vitro data are available but their clinical significance is unknown. Cefotetan has been shown to be active in vitro against most strains of the following organisms:<br/>Gram-Negative Aerobes: Citrobacter species (including C. diversus and C. freundii) Klebsiella oxytoca Moraxella (Branhamella) catarrhalis Neisseria gonorrhoeae (penicillinase-producing strains) Salmonella species Serratia species Shigella species Yersinia enterocolitica<br/>Anaerobes: Porphyromonas asaccharolytica (formerly Bacteroides asaccharolyticus) Prevotella oralis (formerly Bacteroides oralis) Bacteroides splanchnicus Clostridium difficile Propionibacterium species Veillonella species<br/>Susceptibility Tests: Dilution Techniques: Quantitative methods are used to determine antimicrobial minimal inhibitory concentrations (MIC's). These MIC's provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized procedure. Standardized procedures are based on a dilution method(broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations or cefotetan powder. The MIC values should be interpreted according to the following criteria: A report of���Susceptible' indicates that the pathogen is likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable. A report of���Intermediate' indicates that the result should be considered equivocal, and if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of���Resistant' indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected. Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures. Standard cefotetan powder should provide the following MIC values: Diffusion Techniques: Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedurerequires the use of the standardized inoculum concentrations. This procedure uses paper disks impregnated with 30��g cefotetan to test the susceptibility of microorganisms to cefotetan. Reports from the laboratory providing results of the standard single-disk susceptibility test with a 30��g cefotetan disk should be interpreted according to the following criteria: Interpretation should be as stated above for results using dilution techniques. Interpretation involves correlation of the diameter obtained in the disk test with the MIC for cefotetan. As with standardized dilution techniques, diffusion methods require the use of laboratory control microorganisms that are used to control the technical aspects of the laboratory procedures. For the diffusion technique, the 30��g cefotetan disk should provide the following zone diameters in these laboratory test quality control strains. Anaerobic Techniques: For anaerobic bacteria, the susceptibility to cefotetan as MIC's can be determined by standardized test methods. The MIC values obtained should be interpreted according to the following criteria: Interpretation is identical to that stated above for results using dilution techniques. As with other susceptibility techniques, the use of laboratory control microorganisms is required to control the technical aspects of the laboratory standardized procedures. Standardized cefotetan powder should provide the following MIC values:

General:: Prescribing CEFOTANin the absence of a proven or strongly suspected bacterial infection of a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. As with other broad-spectrum antibiotics, prolonged use of CEFOTAN may result in overgrowth of nonsusceptible organisms. Careful observation of the patient is essential. If superinfection does occur during therapy, appropriate measures should be taken. CEFOTAN should be used with caution in individuals with a history of gastrointestinal disease, particularly colitis.<br/>Information for Patients:: Patients should be counseled that antibacterial drugs, including CEFOTAN, should only be used to treat bacterial infections. They do not treat viral infections (eg, the common cold). When CEFOTANis prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment, and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by CEFOTANor other antibacterial drugs in the future. As with some other cephalosporins, a disulfiram-like reaction characterized by flushing, sweating, headache, and tachycardia may occur when alcohol (beer, wine, etc.) is ingested within 72 hours after CEFOTAN administration. Patients should be cautioned about the ingestion of alcoholic beverages following the administration ofCEFOTAN.<br/>Drug Interactions:: Increases in serum creatinine have occurred when CEFOTAN was given alone. If CEFOTAN and an aminoglycoside are used concomitantly, renal function should be carefully monitored, because nephrotoxicity may be potentiated.<br/>Drug/Laboratory Test Interactions:: The administration of CEFOTAN may result in a false positive reaction for glucose in the urine using Clinitest���, Benedict's solution, or Fehling's solution. It is recommended that glucose tests based on enzymatic glucose oxidase be used. As with other cephalosporins, high concentrations of cefotetan may interfere with measurement of serum and urine creatinine levels by Jaffe��reaction and produce false increases in the levels of creatinine reported.<br/>Carcinogenesis, Mutagenesis, Impairment of Fertility:: Although long-term studies in animals have not been performed to evaluate carcinogenic potential, no mutagenic potential of cefotetan was found in standard laboratory tests. Cefotetan has adverse effects on the testes of prepubertal rats. Subcutaneous administration of 500 mg/kg/day (approximately 8-16 times the usual adult human dose) on days 6-35 of life (thought to be developmentally analogous to late childhood and prepuberty in humans) resulted in reduced testicular weight and seminiferous tubule degeneration in 10 of 10 animals. Affected cells included spermatogonia and spermatocytes; Sertoli and Leydig cells were unaffected. Incidence and severity of lesions were dose-dependent; at 120 mg/kg/day (approximately 2-4 times the usual human dose) only 1 of 10 treated animals was affected, and the degree of degeneration was mild. Similar lesions have been observed in experiments of comparable design with other methylthiotetrazole-containing antibiotics and impaired fertility has been reported, particularly at high dose levels. No testicular effects were observed in 7-week-old rats treated with up to 1000 mg/kg/day SC for 5 weeks, or in infant dogs (3 weeks old) that received up to 300 mg/kg/day IV for 5 weeks. The relevance of these findings to humans is unknown.<br/>Pregnancy::<br/>Teratogenic Effects: Pregnancy Category B:: Reproduction studies have been performed in rats and monkeys at doses up to 20 times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to cefotetan. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.<br/>Nursing Mothers:: Cefotetan is excreted in human milk in very low concentrations. Caution should be exercised when cefotetan is administered to a nursing woman.<br/>Pediatric Use:: Safety and effectiveness in children have not been established.<br/>Geriatric Use:: Of the 925 subjects who received cefotetan in clinical studies, 492 (53%) were 60 years and older, while 76 (8%) were 80 years and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and the other reported clinical experience has not identified differences in responses between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. .

In clinical studies, the following adverse effects were considered related to CEFOTAN therapy. Those appearing in italics have been reported during postmarketing experience.<br/>Gastrointestinal:: Symptoms occurred in 1.5% of patients, the most frequent were diarrhea (1 in 80) and nausea (1 in 700); pseudomembranous colitis. Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment or surgical prophylaxis.<br/>Hematologic:: Laboratory abnormalities occurred in 1.4% of patients and included eosinophilia (1 in 200), positive direct Coombs' test (1 in 250), and thrombocytosis (1 in 300); agranulocytosis, hemolytic anemia, leukopenia, thrombocytopenia, and prolonged prothrombin time with or without bleeding.<br/>Hepatic:: Enzyme elevations occurred in 1.2% of patients and included a rise in ALT (SGPT) (1 in 150), AST (SGOT) (1 in 300), alkaline phosphatase (1 in 700), and LDH (1 in 700).<br/>Hypersensitivity:: Reactions were reported in 1.2% of patients and included rash (1 in 150) and itching (1 in 700); anaphylactic reactions and urticaria.<br/>Local:: Effects were reported in less than 1% of patients and included phlebitis at the site of injection (1 in 300), and discomfort (1 in 500).<br/>Renal:: Elevations in BUN and serum creatinine have been reported.<br/>Urogenital:: Nephrotoxicity has rarely been reported.<br/>Miscellaneous:: Fever In addition to the adverse reactions listed above which have been observed in patients treated with cefotetan, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibiotics: pruritus, Stevens-Johnson syndrome, erythema multiforme, toxic epidermal necrolysis, vomiting, abdominal pain, colitis, superinfection, vaginitis including vaginal candidiasis, renal dysfunction, toxic nephropathy, hepatic dysfunction including cholestasis, aplastic anemia, hemorrhage, elevated bilirubin, pancytopenia, and neutropenia. Several cephalosporins have been implicated in triggering seizures, particularly in patients with renal impairment, when the dosage was not reduced. If seizures associated with drug therapy occur, the drug should be discontinued. Anticonvulsant therapy can be given if clinically indicated.

| dailymed-instance:warning |
BEFORE THERAPY WITH CEFOTAN IS INSTITUTED, CAREFUL INQUIRY SHOULD BE MADE TO DETERMINE WHETHER THE PATIENT HAS HAD PREVIOUS HYPERSENSITIVITY REACTIONS TO CEFOTETAN DISODIUM, CEPHALOSPORINS, PENICILLINS, OR OTHER DRUGS. IF THIS PRODUCT IS TO BE GIVEN TO PENICILLIN-SENSITIVE PATIENTS, CAUTION SHOULD BE EXERCISED BECAUSE CROSS-HYPERSENSITIVITY AMONG BETA-LACTAM ANTIBIOTICS HAS BEEN CLEARLY DOCUMENTED AND MAY OCCUR IN UP TO 10% OF PATIENTS WITH A HISTORY OF PENICILLIN ALLERGY. IF AN ALLERGIC REACTION TO CEFOTAN OCCURS, DISCONTINUE THE DRUG. SERIOUS ACUTE HYPERSENSITIVITY REACTIONS MAY REQUIRE TREATMENT WITH EPINEPHRINE AND OTHER EMERGENCY MEASURES, INCLUDING OXYGEN, INTRAVENOUS FLUIDS, INTRAVENOUS ANTIHISTAMINES, CORTICOSTEROIDS, PRESSOR AMINES, AND AIRWAY MANAGEMENT, AS CLINICALLY INDICATED. AN IMMUNE MEDIATED HEMOLYTIC ANEMIA HAS BEEN OBSERVED IN PATIENTS RECEIVING CEPHALOSPORIN CLASS ANTIBIOTICS. SEVERE CASES OF HEMOLYTIC ANEMIA, INCLUDING FATALITIES, HAVE BEEN REPORTED IN ASSOCIATION WITH THE ADMINISTRATION OF CEFOTETAN. SUCH REPORTS ARE UNCOMMON. THERE APPEARS TO BE AN INCREASED RISK OF DEVELOPING HEMOLYTIC ANEMIA ON CEFOTETAN RELATIVE TO OTHER CEPHALOSPORINS OF AT LEAST 3 FOLD. IF A PATIENT DEVELOPS ANEMIA ANYTIME WITHIN 2-3 WEEKS SUBSEQUENT TO THE ADMINISTRATION OF CEFOTETAN, THE DIAGNOSIS OF A CEPHALOSPORIN ASSOCIATED ANEMIA SHOULD BE CONSIDERED AND THE DRUG STOPPED UNTIL THE ETIOLOGY IS DETERMINED WITH CERTAINTY. BLOOD TRANSFUSIONS MAY BE CONSIDERED AS NEEDED . PATIENTS WHO RECEIVE COURSES OF CEFOTETAN FOR THE TREATMENT OR PROPHYLAXIS OF INFECTIONS SHOULD HAVE PERIODIC MONITORING FOR SIGNS AND SYMPTOMS OF HEMOLYTIC ANEMIA INCLUDING A MEASUREMENT OF HEMATOLOGICAL PARAMETERS WHERE APPROPRIATE. Pseudomembranous colitis has been reported with nearly all antibacterial agents, including cefotetan, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is a primary cause of���antibiotic-associated colitis���. After the diagnosis of pseudomembranous colitis has been established, appropriate therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis. In common with many other broad-spectrum antibiotics, CEFOTAN may be associated with a fall in prothrombin activity and, possibly, subsequent bleeding. Those at increased risk include patients with renal or hepatobiliary impairment or poor nutritional state, the elderly, and patients with cancer. Prothrombin time should be monitored and exogenous vitamin K administered as indicated.

| dailymed-instance:indicatio... |
To reduce the development of drug-resistant bacteria and maintain the effectiveness of CEFOTAN and other antibacterial drugs, CEFOTAN should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antimicrobial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.<br/>Treatment: CEFOTAN is indicated for the therapeutic treatment of the following infections when caused by susceptible strains of the designated organisms:<br/>Urinary Tract Infections caused by E. coli, Klebsiella spp (including K. pneumoniae), Proteus mirabilis and Proteus spp (which may include the organisms now called Proteus vulgaris, Providencia rettgeri, and Morganella morganii).:<br/>Lower Respiratory Tract Infections caused by Streptococcus pneumoniae, Staphylococcus aureus (penicillinase- and nonpenicillinase-producing strains), Haemophilus influenzae (including ampicillin-resistant strains), Klebsiella species (including K. pneumoniae), E. coli, Proteus mirabilis, and Serratia marcescens*.:<br/>Skin and Skin Structure Infections due to Staphylococcus aureus (penicillinase- and nonpenicillinase-producing strains), Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus species (excluding enterococci), Escherichia coli, Klebsiella pneumoniae, Peptococcus niger*, Peptostreptococcus species.:<br/>Gynecologic Infections caused by Staphylococcus aureus, (including penicillinase- and nonpenicillinase-producing strains), Staphylococcus epidermidis, Streptococcus species (excluding enterococci), Streptococcus agalactiae, E. coli, Proteus mirabilis, Neisseria gonorrhoeae, Bacteroides species (excluding B. distasonis, B. ovatus, B. thetaiotaomicron), Fusobacterium species*, and gram-positive anaerobic cocci (including Peptococcus niger and Peptostreptococcus species).: Cefotetan, like other cephalosporins, has no activity against Chlamydia trachomatis. Therefore, when cephalosporins are used in the treatment of pelvic inflammatory disease, and C. trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added.<br/>Intra-abdominal Infections caused by E. coli, Klebsiella species (including K. pneumoniae), Streptococcus species (excluding enterococci), Bacteroides species (excluding B. distasonis, B. ovatus, B. thetaiotaomicron) and Clostridium species*.:<br/>Bone and Joint Infections caused by Staphylococcus aureus.*: *Efficacy for this organism in this organ system was studied in fewer than ten infections. Specimens for bacteriological examination should be obtained in order to isolate and identify causative organisms and to determine their susceptibilities to cefotetan. Therapy may be instituted before results of susceptibility studies are known; however, once these results become available, the antibiotic treatment should be adjusted accordingly. In cases of confirmed or suspected gram-positive or gram-negative sepsis or in patients with other serious infections in which the causative organism has not been identified, it is possible to use CEFOTAN concomitantly with an aminoglycoside. Cefotetan combinations with aminoglycosides have been shown to be synergistic in vitro against many Enterobacteriaceae and also some other gram-negative bacteria. The dosage recommended in the labeling of both antibiotics may be given and depends on the severity of the infection and the patient's condition. NOTE: Increases in serum creatinine have occurred when CEFOTAN was given alone. If CEFOTAN and an aminoglycoside are used concomitantly, renal function should be carefully monitored, because nephrotoxicity may be potentiated.<br/>Prophylaxis: The preoperative administration of CEFOTAN may reduce the incidence of certain postoperative infections in patients undergoing surgical procedures that are classified as clean contaminated or potentially contaminated (eg, cesarean section, abdominal or vaginal hysterectomy, transurethral surgery, biliary tract surgery, and gastrointestinal surgery). If there are signs and symptoms of infection, specimens for culture should be obtained for identification of the causative organism so that appropriate therapeutic measures may be initiated.
