1 INDICATIONS AND USAGE Ceftriaxone for Injection and Dextrose Injection is indicated for the treatment of the following infections when caused by susceptible bacteria. Ceftriaxone for Injection and Dextrose Injection is a cephalosporin antibacterial indicated for the treatment of the following infections caused by susceptible isolates of the designated bacteria: Lower Respiratory Tract Infections ( 1.1 ); Skin and Skin Structure Infections ( 1.2 ); Complicated and Uncomplicated Urinary Tract Infections ( 1.3 ); Pelvic Inflammatory Disease ( 1.4 ); Bacterial Septicemia ( 1.5 ); Bone and Joint Infections ( 1.6 ); Intra-abdominal Infections ( 1.7 ); Meningitis ( 1.8 ); and Surgical Prophylaxis ( 1.9 ). To reduce the development of drug-resistant bacteria and maintain the effectiveness of Ceftriaxone for Injection and Dextrose Injection and other antibacterial drugs, Ceftriaxone for Injection and Dextrose Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.10 ) 1.1 Lower Respiratory Tract Infections Lower respiratory tract infections caused by Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Escherichia coli, Enterobacter aerogenes, Proteus mirabilis or Serratia marcescens . 1.2 Skin and Skin Structure Infections Skin and skin structure infections caused by Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Viridans group streptococci, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Morganella morganii The efficacy for these organisms in this organ system were studied in fewer than ten infections. , Pseudomonas aeruginosa, Serratia marcescens, Acinetobacter calcoaceticus, Bacteroides fragilis or Peptostreptococcus species. 1.3 Complicated and Uncomplicated Urinary Tract Infections Complicated and uncomplicated urinary tract infections caused by Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii or Klebsiella pneumoniae . 1.4 Pelvic Inflammatory Disease Pelvic inflammatory disease caused by Neisseria gonorrhoeae . Ceftriaxone sodium, like other cephalosporins, has no activity against Chlamydia trachomatis . Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and Chlamydia trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added. 1.5 Bacterial Septicemia Bacterial septicemia caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae or Klebsiella pneumoniae . 1.6 Bone and Joint Infections Bone and joint infections caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae or Enterobacter species. 1.7 Intra-abdominal Infections Intra-abdominal infections caused by Escherichia coli, Klebsiella pneumoniae, Bacteroides fragilis, Clostridium species or Peptostreptococcus species. 1.8 Meningitis Meningitis caused by Haemophilus influenzae, Neisseria meningitidis or Streptococcus pneumoniae . Ceftriaxone sodium has also been used successfully in a limited number of cases of meningitis and shunt infection caused by Staphylococcus epidermidis and Escherichia coli , however, the efficacy for these organisms in this organ system were studied in fewer than ten infections. 1.9 Surgical Prophylaxis The preoperative administration of a single 1 g dose of Ceftriaxone for Injection and Dextrose Injection may reduce the incidence of postoperative infections in patients undergoing surgical procedures classified as contaminated or potentially contaminated (e.g., vaginal or abdominal hysterectomy or cholecystectomy for chronic calculous cholecystitis in high-risk patients, such as those over 70 years of age, with acute cholecystitis not requiring therapeutic antimicrobials, obstructive jaundice or common duct bile …

6 ADVERSE REACTIONS The following serious adverse reactions to ceftriaxone are described below and elsewhere in the labeling: Hypersensitivity reactions [see Warnings and Precautions (5.1) ] Ceftriaxone-calcium precipitates [see Warnings and Precautions (5.2) and Drug Interactions (7.2) ] Neurological Adverse Reactions [see Warnings and Precautions (5.3) ] Clostridioides difficile -associated diarrhea [see Warnings and Precautions (5.4) ] Hemolytic anemia [see Warnings and Precautions (5.5) ] The most common adverse reactions occurring in greater than 2% of patients receiving ceftriaxone include diarrhea, eosinophilia, thrombocytosis, leukopenia, and elevations of SGOT and SGPT. To report SUSPECTED ADVERSE REACTIONS, contact B. Braun Medical Inc. at 1-800-854-6851 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following reactions occurred in less than or equal to 6% of the patients: Local reactions—pain, induration, tenderness, and phlebitis after IV administration. Hypersensitivity—rash, pruritus, fever or chills. Hematologic—eosinophilia, thrombocytosis, leucopenia, anemia, hemolytic anemia, neutropenia, lymphopenia, thrombocytopenia, and prolongation of the prothrombin time. Gastrointestinal—diarrhea, nausea or vomiting, and dysgeusia. The onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment [see Warnings and Precautions (5.4) ]. Hepatic—elevations of SGOT, SGPT, alkaline phosphatase, bilirubin. Renal—elevations of the BUN, creatinine, and the presence of casts in the urine. Central nervous system—headache or dizziness. Genitourinary—moniliasis or vaginitis. Miscellaneous—diaphoresis and flushing. Ceftriaxone-calcium precipitates—Cases of fatal reactions with ceftriaxone-calcium precipitates in lung and kidneys in neonates have been described. In some cases the infusion lines and times of administration of ceftriaxone and calcium-containing solutions differed [see Warnings and Precautions (5.2) and Drug Interactions (7.2) ]. Other observed adverse reactions—abdominal pain, agranulocytosis, allergic pneumonitis, anaphylaxis, basophilia, biliary lithiasis, bronchospasm, colitis, dyspepsia, epistaxis, flatulence, gallbladder sludge, glycosuria, hematuria, jaundice, leukocytosis, lymphocytosis, monocytosis, nephrolithiasis, palpitations, a decrease in the prothrombin time, renal precipitations, seizures, and serum sickness. 6.2 Postmarketing Experience The following adverse reactions have been reported during postapproval use of ceftriaxone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to readily estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal—stomatitis and glossitis. Genitourinary—oliguria, ureteric obstruction, post-renal acute renal failure. Hepatic—hepatitis. Dermatologic—severe cutaneous adverse reactions (erythema multiforme, Stevens-Johnson syndrome or Lyell’s syndrome/toxic epidermal necrolysis), exanthema, allergic dermatitis, urticaria, and edema. Immunologic—Anaphylaxis (anaphylactic shock, transient leucopenia, neutropenia, agranulocytosis and thrombocytopenia). Neurologic – Encephalopathy, seizures, myoclonus, and non-convulsive status epilepticus [see Warnings and Precautions (5.3) ]. 6.3 Cephalosporin-class Adverse Reactions In addition to the adverse reactions listed above that have been observed in patients treated with ceftriaxone, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibacterials: Adverse Reactions: Allergic reactions, drug fever, serum sickness-like reaction, renal dysfunction, toxic nephropa …

7 DRUG INTERACTIONS Vancomycin, amsacrine, aminoglycosides, and fluconazole are physically incompatible. ( 7.1 ) Calcium-containing products: precipitation can occur. ( 7.2 ) 7.1 Vancomycin, Amsacrine, Aminoglycosides, and Fluconazole Vancomycin, amsacrine, aminoglycosides, and fluconazole are physically incompatible with ceftriaxone in admixtures [see Dosage and Administration (2.3) ]. 7.2 Calcium-containing Products Precipitation of ceftriaxone-calcium can occur when Ceftriaxone for Injection and Dextrose Injection is mixed with calcium-containing solutions in the same IV administration line. Ceftriaxone for Injection and Dextrose Injection must not be administered simultaneously with calcium-containing IV solutions. Ceftriaxone for Injection and Dextrose Injection and calcium-containing solutions may be administered sequentially. [see Warnings and Precautions (5.2) ]

8 USE IN SPECIFIC POPULATIONS Hepatic and renal impairment Patients with both hepatic and renal impairment should not receive more than 2 grams of ceftriaxone per day ( 5.8 ) Pediatric Patients Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container is designed to deliver a 1 g or 2 g dose of ceftriaxone. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full adult dose of ceftriaxone. ( 2.2 , 8.4 ) 8.1 Pregnancy Risk Summary Available data from published prospective cohort studies, case series, and case reports over several decades with cephalosporin use, including Ceftriaxone, in pregnant women have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Ceftriaxone crosses the placenta. In animal reproduction studies, no adverse developmental effects were observed when ceftriaxone was administered to pregnant rats at doses up to approximately 2.8 times the clinical dose of 2 g/day (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data Published literature shows that ceftriaxone crosses the placenta. While available studies cannot definitively establish the absence of risk, published data from case-control studies and case reports over several decades have not identified an association with cephalosporin use during pregnancy and major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Available studies have methodologic limitations, including small sample size, retrospective data collection, and inconsistent comparator groups. Animal Data Reproductive studies have been performed in mice, rats, and primates at intravenous doses of 625, 586, and 84 mg/kg/day, respectively, without evidence of embryotoxicity, fetotoxicity, or teratogenicity. These doses are approximately 1.5, 2.8, and 0.8 times the clinical dose of 2 g/day based on body surface area comparisons. Ceftriaxone was tested in a Segment III (pre-postnatal) study in rats at intravenous doses of up to 586 mg/kg/day (approximately 2.8 times the clinical dose of 2 g/day based on body surface area comparison). No adverse effects were noted on various reproductive parameters during gestation and lactation, including postnatal growth, functional behavior, and reproductive ability of the offspring. 8.2 Lactation Risk Summary Data from published literature report that ceftriaxone is present in human milk. There are no data on the effects of Ceftriaxone on the breastfed child or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Ceftriaxone for Injection and Dextrose Injection and any potential adverse effects on the breastfed child from Ceftriaxone for Injection and Dextrose Injection or from the mother’s underlying condition. 8.4 Pediatric Use Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container is designed to deliver a 1 g or 2 g dose of ceftriaxone. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full 1 g or 2 g adult dose of ceftriaxone. 8.5 Geriatric Use Of the total number of subjects in clinical studies of ceftriaxone sodium, 32% were 60 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Ceftriaxone is known to be substantially exc …
