How Much Does Cefuroxime Cost in Mexico vs the USA?

INDICATIONS AND USAGE Cefuroxime for Injection USP and Dextrose 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 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 may be used concomitantly with an aminoglycoside (see PRECAUTIONS ). The recommended doses of both antibacterials 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 Dextrose Injection USP and other antibacterial drugs, Cefuroxime for Injection USP and Dextrose 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 and Dextrose 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 antibacterials in surgery depends on the time of administration. Cefuroxime for Injection USP and Dextrose Injection USP should usually be given one-half to 1 hour before the operation to allow sufficient time to achieve effective antibacterial 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 antibacterial 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 and Dextrose 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 cefuroxime therapy 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.

DOSAGE AND ADMINISTRATION This product is intended for intravenous administration only. Dosage: Adults: The usual adult dosage range for cefuroxime is 750 mg to 1.5 grams every 8 hours, usually for 5 to 10 days. In uncomplicated urinary tract infections, skin and skin-structure infections, disseminated gonococcal infections, and uncomplicated pneumonia, a 750 mg dose every 8 hours is recommended. In severe or complicated infections, a 1.5 gram dose every 8 hours is recommended. In bone and joint infections, a 1.5 gram dose every 8 hours is recommended. In clinical trials, surgical intervention was performed when indicated as an adjunct to cefuroxime therapy. A course of oral antibacterials was administered when appropriate following the completion of parenteral administration of cefuroxime. In life-threatening infections or infections due to less susceptible organisms, 1.5 grams every 6 hours may be required. In bacterial meningitis, the dosage should not exceed 3 grams every 8 hours. For preventive use for clean-contaminated or potentially contaminated surgical procedures, a 1.5 gram dose administered intravenously just before surgery (approximately one-half to 1 hour before the initial incision) is recommended. Thereafter, give 750 mg intravenously every 8 hours when the procedure is prolonged. For preventive use during open heart surgery, a 1.5 gram dose administered intravenously at the induction of anesthesia and every 12 hours thereafter for a total of 6 grams is recommended. Impaired Renal Function: A reduced dosage must be employed when renal function is impaired. Dosage should be determined by the degree of renal impairment and the susceptibility of the causative organism (see Table 2 ). Table 2: Dosage of Cefuroxime in Adults with Reduced Renal Function Creatinine Clearance (mL/min) Dose Frequency >20 750 mg–1.5 grams q8h 10–20 750 mg q12h <10 750 mg q24h Since cefuroxime is dialyzable, patients on hemodialysis should be given a further dose at the end of the dialysis. When only serum creatinine is available, the following formula 1 (based on sex, weight, and age of the patient) may be used to convert this value into creatinine clearance. The serum creatinine should represent a steady state of renal function. Males: Creatinine clearance (mL/min) = Weight (kg) × (140 - age) 72 × serum creatinine (mg/dL) Females: 0.85 × male value Note: As with antibacterial therapy in general, administration of Cefuroxime for Injection USP and Dextrose Injection USP should be continued for a minimum of 48 to 72 hours after the patient becomes asymptomatic or after evidence of bacterial eradication has been obtained; a minimum of 10 days of treatment is recommended in infections caused by Streptococcus pyogenes in order to guard against the risk of rheumatic fever or glomerulonephritis; frequent bacteriologic and clinical appraisal is necessary during therapy of chronic urinary tract infection and may be required for several months after therapy has been completed; persistent infections may require treatment for several weeks; and doses smaller than those indicated above should not be used. In staphylococcal and other infections involving a collection of pus, surgical drainage should be carried out where indicated. Pediatric Patients Above 3 Months of Age: Administration of 50 to 100 mg/kg/day in equally divided doses every 6 to 8 hours has been successful for most infections susceptible to cefuroxime. The higher dosage of 100 mg/kg/day (not to exceed the maximum adult dosage) should be used for the more severe or serious infections. In bone and joint infections, 150 mg/kg/day (not to exceed the maximum adult dosage) is recommended in equally divided doses every 8 hours. In clinical trials, a course of oral antibacterials was administered to pediatric patients following the completion of parenteral administration of cefuroxime. In cases of bacterial meningitis, a larger dosage of cefuroxime is recommended, 200 to 240 mg/kg/day intravenously in divided doses every 6 to 8 hours. In pediatric patients with renal insufficiency, the frequency of dosing should be modified consistent with the recommendations for adults. Cefuroxime for Injection USP and Dextrose for Injection USP in the DUPLEX® Container is designed to deliver a 750 mg or 1.5 g dose of cefuroxime. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full adult dose. For intermittent IV infusion with a Y-type administration set, dosing can be accomplished through the tubing system by which the patient may be receiving other IV solutions. However, during infusion of the solution containing Cefuroxime, it is advisable to temporarily discontinue administration of any other solutions at the same site. Solutions of cefuroxime, like those of most beta-lactam antibacterials, should not be added to solutions of aminoglycoside antibacterials because of potential interaction. However, if concurrent therapy with cefuroxime and an aminoglycoside is indicated, each of these antibacterials can be administered separately to the same patient. Use sterile equipment. Caution: Do not use plastic containers in series connections. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete. DUPLEX® Container Directions for Use To avoid inadvertent activation, DUPLEX® Container should remain in the folded position until activation is intended. Patient Labeling and Drug Powder/Diluent Inspection Apply patient-specific label on foil side of container. USE CARE to avoid activation. Do not cover any portion of foil strip with patient label. Unlatch side tab and unfold DUPLEX® Container. (See Diagram 1.) Visually inspect diluent chamber for particulate matter. Use only if container and seals are intact. To inspect the drug powder for foreign matter or discoloration, peel foil strip from drug chamber. (See Diagram 2.) Protect from light after removal of foil strip. Note: If foil strip is removed, product must be used within 7 days, but not beyond the labeled expiration date. The product should be re-folded and the side tab latched until ready to activate. Reconstitution (Activation) Do not use directly after storage by refrigeration, allow the product to equilibrate to room temperature before patient use. Unfold the DUPLEX® Container and point the set port in a downward direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the diluent meniscus trapping all air above the fold. To activate, squeeze the folded diluent chamber until the seal between the diluent and powder opens, releasing diluent into the drug powder chamber. (See Diagram 3.) Agitate the liquid-powder mixture until the drug powder is completely dissolved. Note: Following reconstitution ( activation ), product must be used within 24 hours if stored at room temperature or within 7 days if stored under refrigeration. Administration Visually inspect the reconstituted solution for particulate matter. Point the set port in a downwards direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the solution meniscus trapping all air above the fold. Squeeze the folded DUPLEX® Container until the seal between reconstituted drug solution and set port opens, releasing liquid to set port. (See Diagram 4.) Prior to attaching the IV set, check for minute leaks by squeezing container firmly. If leaks are found, discard container and solution as sterility may be impaired. Using aseptic technique, peel foil cover from the set port and attach sterile administration set. (See Diagram 5.) Refer to Directions for Use accompanying the administration set. Precautions As with other cephalosporins, reconstituted Cefuroxime for Injection USP and Dextrose Injection USP tends to darken depending on storage conditions, within the stated recommendations. However, product potency is not adversely affected. Use only if prepared solution is clear and free from particulate matter. Do not use in series connection. Do not introduce additives into the DUPLEX® Container. Do not freeze. Diagram 1 Diagram 2 Diagram 3 Diagram 4 Diagram 5

WARNINGS BEFORE THERAPY WITH CEFUROXIME FOR INJECTION USP AND DEXTROSE INJECTION USP IS INSTITUTED, CAREFUL INQUIRY SHOULD BE MADE TO DETERMINE WHETHER THE PATIENT HAS HAD PREVIOUS HYPERSENSITIVITY REACTIONS TO CEPHALOSPORINS, PENICILLINS OR OTHER DRUGS. THIS PRODUCT SHOULD BE GIVEN CAUTIOUSLY TO PENICILLIN-SENSITIVE PATIENTS. ANTIBACTERIALS SHOULD BE ADMINISTERED WITH CAUTION TO ANY PATIENT WHO HAS DEMONSTRATED SOME FORM OF ALLERGY, PARTICULARLY TO DRUGS. IF AN ALLERGIC REACTION TO CEFUROXIME OCCURS, DISCONTINUE THE DRUG. SERIOUS ACUTE HYPERSENSITIVITY REACTIONS MAY REQUIRE EPINEPHRINE AND OTHER EMERGENCY MEASURES. Clostridioides difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Cefuroxime for Injection USP and Dextrose Injection USP, 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 use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial 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.

ADVERSE REACTIONS Cefuroxime 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 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: In addition to the adverse events reported during clinical trials, the following events have been observed during clinical practice in patients treated with cefuroxime and were reported spontaneously. Data are generally insufficient to allow an estimate of incidence or to establish causation. Immune System Disorders: Angioedema, acute myocardial ischemia with or without myocardial infarction may occur as part of an allergic reaction. Neurologic 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 antibacterials: Adverse Reactions: Vomiting, abdominal pain, colitis, vaginitis including vaginal candidiasis, toxic nephropathy, hepatic dysfunction including cholestasis, aplastic anemia, hemolytic anemia, and hemorrhage. Several cephalosporins, including cefuroxime, 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.

Pregnancy Teratogenic Effects Reproduction studies have been performed in mice at doses up to 6,400 mg/kg/day (6.3 times the recommended maximum human dose based on mg/m 2 ), and rabbits at doses up to 400 mg/kg/day (2.1 times the recommended maximum human dose based on mg/m 2 ) and have revealed no evidence of impaired fertility or harm to the fetus due to cefuroxime. There are, however, no adequate and well-controlled studies 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.
