Cefuroxime sodium

INDICATIONS AND USAGE Cefuroxime for Injection, USP is indicated for the treatment of patients with infections caused by susceptible strains of the designated organisms in the following diseases: Lower Respiratory Tract Infections , including pneumonia, caused by Streptococcus pneumoniae, Haemophilus influenzae (including ampicillin-resistant strains), Klebsiella spp., Staphylococcus aureus (penicillinase- and non-penicillinase- producing strains), Streptococcus pyogenes , and Escherichia coli . Urinary Tract Infections caused by Escherichia coli and Klebsiella spp. Skin and Skin-Structure Infections caused by Staphylococcus aureus (penicillinase- and non-penicillinase-producing strains), Streptococcus pyogenes , Escherichia coli, Klebsiella spp., and Enterobacter spp. Septicemia caused by Staphylococcus aureus (penicillinase- and non-penicillinase- producing strains), Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae (including ampicillin-resistant strains), and Klebsiella spp. Meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae (including ampicillin-resistant strains), Neisseria meningitidis , and Staphylococcus aureus (penicillinase- and non-penicillinase-producing strains). Gonorrhea: Uncomplicated and disseminated gonococcal infections due to Neisseria gonorrhoeae (penicillinase- and non-penicillinase-producing strains) in both males and females. Bone and Joint Infections caused by Staphylococcus aureus (penicillinase- and non- penicillinase-producing strains). Clinical microbiological studies in skin and skin-structure infections frequently reveal the growth of susceptible strains of both aerobic and anaerobic organisms. Cefuroxime for Injection, USP has been used successfully in these mixed infections in which several organisms have been isolated. In certain 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, Cefuroxime for Injection, USP may be used concomitantly with an aminoglycoside (see PRECAUTIONS ). The recommended doses of both antibiotics may be given depending on the severity of the infection and the patient's condition. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cefuroxime for Injection, USP and other antibacterial drugs, Cefuroxime for Injection, USP 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 antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Prevention The preoperative prophylactic administration of Cefuroxime for Injection, USP may prevent the growth of susceptible disease-causing bacteria and thereby may reduce the incidence of certain postoperative infections in patients undergoing surgical procedures (e.g., vaginal hysterectomy) that are classified as clean-contaminated or potentially contaminated procedures. Effective prophylactic use of antibiotics in surgery depends on the time of administration. Cefuroxime for Injection, USP should usually be given one-half to 1 hour before the operation to allow sufficient time to achieve effective antibiotic concentrations in the wound tissues during the procedure. The dose should be repeated intraoperatively if the surgical procedure is lengthy. Prophylactic administration is usually not required after the surgical procedure ends and should be stopped within 24 hours. In the majority of surgical procedures, continuing prophylactic administration of any antibiotic does not reduce the incidence of subsequent infections but will increase the possibility of adverse reactions and the development of bacterial resistance. The perioperative use of Cefuroxime for Injection, USP has also been effective during open heart surgery for surgical patients in whom infections at the operative site would present a serious risk. For these patients it is recommended that therapy with Cefuroxime for Injection, USP be continued for at least 48 hours after the surgical procedure ends. If an infection is present, specimens for culture should be obtained for the identification of the causative organism, and appropriate antimicrobial therapy should be instituted.

ADVERSE REACTIONS Cefuroxime for Injection is generally well tolerated. The most common adverse effects have been local reactions following IV administration. Other adverse reactions have been encountered only rarely. Local Reactions Thrombophlebitis has occurred with IV administration in 1 in 60 patients. Gastrointestinal Gastrointestinal symptoms occurred in 1 in 150 patients and included diarrhea (1 in 220 patients) and nausea (1 in 440 patients). The onset of pseudomembranous colitis may occur during or after antibacterial treatment (see WARNINGS ). Hypersensitivity Reactions Hypersensitivity reactions have been reported in fewer than 1% of the patients treated with Cefuroxime for Injection and include rash (1 in 125). Pruritus, urticaria, and positive Coombs' test each occurred in fewer than 1 in 250 patients, and, as with other cephalosporins, rare cases of anaphylaxis, drug fever, erythema multiforme, interstitial nephritis, toxic epidermal necrolysis, and Stevens-Johnson syndrome have occurred. Blood A decrease in hemoglobin and hematocrit has been observed in 1 in 10 patients and transient eosinophilia in 1 in 14 patients. Less common reactions seen were transient neutropenia (fewer than 1 in 100 patients) and leukopenia (1 in 750 patients). A similar pattern and incidence were seen with other cephalosporins used in controlled studies. As with other cephalosporins, there have been rare reports of thrombocytopenia. Hepatic Transient rise in SGOT and SGPT (1 in 25 patients), alkaline phosphatase (1 in 50 patients), LDH (1 in 75 patients), and bilirubin (1 in 500 patients) levels has been noted. Kidney Elevations in serum creatinine and/or blood urea nitrogen and a decreased creatinine clearance have been observed, but their relationship to cefuroxime is unknown. Postmarketing Experience with Cefuroxime for Injection In addition to the adverse events reported during clinical trials, the following events have been observed during clinical practice in patients treated with Cefuroxime for Injection and were reported spontaneously. Data are generally insufficient to allow an estimate of incidence or to establish causation. Immune System Disorders: Cutaneous vasculitis, angioedema, acute myocardial ischemia with or without myocardial infarction may occur as part of an allergic reaction. Nervous System Disorders: Seizure Cephalosporin-class Adverse Reactions In addition to the adverse reactions listed above that have been observed in patients treated with cefuroxime, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibiotics: Adverse Reactions Vomiting, abdominal pain, colitis, vaginitis including vaginal candidiasis, toxic nephropathy, hepatic dysfunction including cholestasis, aplastic anemia, hemolytic anemia, hemorrhage. Several cephalosporins, including Cefuroxime for Injection, have been implicated in triggering seizures, particularly in patients with renal impairment when the dosage was not reduced (see DOSAGE AND ADMINISTRATION ). If seizures associated with drug therapy should occur, the drug should be discontinued. Anticonvulsant therapy can be given if clinically indicated. Altered Laboratory Tests Prolonged prothrombin time, pancytopenia, agranulocytosis.
