Uses for Cefotaxime
Bone and Joint Infections
Treatment of serious bone and joint infections caused by susceptible S. aureus, streptococci (including S. pyogenes), Pseudomonas (including Ps. aeruginosa), or P. mirabilis.230
Genitourinary Tract Infections
Treatment of serious genitourinary tract infections caused by susceptible S. aureus (including penicillinase-producing strains), S. epidermidis, enterococci, Citrobacter, Enterobacter, E. coli, Klebsiella, Morganella morganii, P. mirabilis, P. vulgaris, Providencia stuartii, P. rettgeri, Pseudomonas (including Ps. aeruginosa), or S. marcescens.230
GI Infections
Empiric treatment of infectious diarrhea† [off-label].412 Alternative for empiric treatment of severe diarrhea in HIV-infected individuals; ciprofloxacin is drug of choice.412
Treatment of gastroenteritis caused by Salmonella† [off-label].197 245 275 412 (See Typhoid Fever and Other Salmonella Infections under Uses.)
Treatment of GI infections caused by Yersinia enterocolitica or Y. pseudotuberculosis† [off-label].218 245 275 Usually self-limited infections, but anti-infectives may be indicated in immunocompromised individuals, for severe infections, or when septicemia or other invasive disease occurs.218 245 275
Gynecologic Infections
Treatment of gynecologic infections (including pelvic inflammatory disease [PID], endometritis, pelvic cellulitis) caused by susceptible S. epidermidis, streptococci (including enterococci), E. coli, Enterobacter, Klebsiella, P. mirabilis, Bacteroides (including B. fragilis), Clostridium, Fusobacterium (including F. nucleatum), Peptococcus, and Peptostreptococcus.230
When parenteral regimen is used for treatment of PID, CDC recommends IV cefoxitin or cefotetan given in conjunction with oral doxycycline or IV clindamycin given in conjunction with gentamicin.167 While other parenteral cephalosporins (e.g., cefotaxime, ceftriaxone) also may be effective, CDC states these drugs are less active than cefoxitin or cefotetan against anaerobic bacteria.167
When oral regimen is used for treatment of mild to moderately severe acute PID, CDC recommends a single IM dose of ceftriaxone, cefoxitin (with oral probenecid), or cefotaxime given in conjunction with oral doxycycline (with or without oral metronidazole).167
Intra-abdominal Infections
Treatment of serious intra-abdominal infections (including peritonitis) caused by susceptible streptococci, E. coli, Klebsiella, P. mirabilis, Clostridium, Bacteroides, or anaerobic cocci (including Peptococcus and Peptostreptococcus).230

Treatment of meningitis and ventriculitis caused by susceptible H. influenzae, N. meningitidis, S. pneumoniae,230 275 291 294 296 335 E. coli, or K. pneumoniae.230 275 291 294 296 336
A drug of choice when a third generation cephalosporin is indicated for empiric treatment of bacterial meningitis;275 290 296 319 should not be used alone for empiric treatment when Listeria monocytogenes, enterococci, staphylococci, or Ps. aeruginosa may be involved.275 290 296 319
Treatment of brain abscesses and other CNS infections† [off-label] (e.g., subdural empyema, intracranial epidural abscesses).319 336 347 Concomitant metronidazole usually recommended for empiric therapy;319 347 used in conjunction with a penicillinase-resistant penicillin or vancomycin if staphylococci suspected.319 347
Respiratory Tract Infections
Treatment of serious lower respiratory tract infections, including community-acquired pneumonia (CAP)197 269 342 caused by susceptible Streptococcus pneumoniae, S. pyogenes (group A β-hemolytic streptococci), other streptococci (except enterococci), Staphylococcus aureus (including penicillinase-producing strains), Escherichia coli, Klebsiella, Haemophilus influenzae (including ampicillin-resistant strains), H. parainfluenzae, Proteus mirabilis, indole-positive Proteus, Serratia marcescens, Enterobacter, or Pseudomonas (including Ps. aeruginosa).230
Recommended by ATS and IDSA as an alternative for treatment of CAP caused by penicillin-susceptible S. pneumoniae and as a preferred drug for treatment of CAP caused by penicillin-resistant S. pneumoniae, provided in vitro susceptibility has been demonstrated.269 Also recommended in certain combination regimens used for empiric treatment of CAP.269 Select regimen for empiric treatment of CAP based on most likely pathogens and local susceptibility patterns; after pathogen is identified, modify to provide more specific therapy (pathogen-directed therapy).269
For empiric inpatient treatment of CAP in patients not requiring treatment in an intensive care unit (non-ICU patients), IDSA and ATS recommend monotherapy with a fluoroquinolone (moxifloxacin, gemifloxacin, levofloxacin) or, alternatively, a combination regimen that includes a β-lactam (usually cefotaxime, ceftriaxone, or ampicillin) given in conjunction with a macrolide (azithromycin, clarithromycin, erythromycin).269
For empiric inpatient treatment of CAP in ICU patients when Pseudomonas and oxacillin-resistant (methicillin-resistant) S. aureus are not suspected, IDSA and ATS recommend a combination regimen that includes a β-lactam (cefotaxime, ceftriaxone, fixed combination of ampicillin and sulbactam) given in conjunction with either azithromycin or a fluoroquinolone (moxifloxacin, gemifloxacin, levofloxacin).269
Septicemia
Treatment of bacteremia/septicemia caused by E. coli, Klebsiella, S. marcescens, S. aureus, or streptococci (including S. pneumoniae).230 An aminoglycoside often is used concomitantly.230
Select anti-infective for treatment of sepsis syndrome based on probable source of infection, causative organism, immune status of patient, and local patterns of bacterial resistance.197
For initial treatment of life-threatening sepsis in adults, some clinicians suggest that a third or fourth generation cephalosporin (cefepime, cefotaxime, ceftriaxone, ceftazidime), the fixed combination of piperacillin and tazobactam, or a carbapenem (doripenem, imipenem, meropenem) be used in conjunction with vancomycin; some also suggest including an aminoglycoside or fluoroquinolone during initial few days of treatment.197

Lyme Disease
Treatment of early neurologic Lyme disease† with acute neurologic manifestations such as meningitis or radiculopathy.273 275 351 354 IV ceftriaxone is the drug of choice; alternatives are IV cefotaxime or IV penicillin G.273 275 351 354 Although an oral regimen (doxycycline, amoxicillin, cefuroxime axetil) may be effective for early localized or early disseminated Lyme disease associated with erythema migrans in the absence of specific neurologic manifestations or advanced atrioventricular (AV) heart block,270 273 275 284 285 286 287 338 351 353 355 356 357 a parenteral regimen usually is recommended when there are acute neurologic manifestations.270 273 275 284 285 286 287 338 351 353 355 356
Treatment of Lyme carditis† when a parenteral regimen is indicated.273 275 351 354 IV ceftriaxone is the drug of choice; alternatives are IV cefotaxime or IV penicillin G.273 275 351 354 Although a parenteral regimen usually is recommended for initial treatment of hospitalized patients, an oral regimen (doxycycline, amoxicillin, cefuroxime axetil) can be used to complete therapy and for the treatment of outpatients.273 275 351 354
Treatment of Lyme arthritis† when a parenteral regimen is indicated.273 275 351 354 361 IV ceftriaxone is the drug of choice; alternatives are IV cefotaxime or IV penicillin G.273 275 351 354 361 Although the comparative safety and efficacy of oral versus IV anti-infectives for treatment of Lyme arthritis have not been fully evaluated,351 those with concomitant neurologic disease generally should receive a parenteral regimen.273 275 351 354 361
Treatment of late neurologic Lyme disease† affecting the CNS or peripheral nervous system (e.g., encephalopathy, neuropathy).351 IV ceftriaxone is the drug of choice; alternatives are IV cefotaxime or IV penicillin G.351
Typhoid Fever and Other Salmonella Infections
Treatment of typhoid fever (enteric fever) or septicemia caused by Salmonella typhi or S. paratyphi†, including multidrug-resistant strains.275 306
Treatment of gastroenteritis caused by Salmonella† (e.g., S. enteritidis, S. typhimurium) in individuals with severe Salmonella gastroenteritis and in those who are at increased risk of invasive disease.197 245 275 412
Alternative for treatment of Salmonella gastroenteritis in HIV-infected individuals to prevent extraintestinal spread of the infection.412 CDC, NIH, and IDSA recommend ciprofloxacin as drug of choice for treatment of Salmonella gastroenteritis (with or without bacteremia) in HIV-infected adults; other fluoroquinolones (levofloxacin, moxifloxacin) also may be effective.412 Depending on in vitro susceptibility, alternatives are co-trimoxazole or third generation cephalosporins (ceftriaxone, cefotaxime).412
Vibrio Infections
Treatment of severe Vibrio parahaemolyticus† infection when anti-infective therapy is indicated in addition to supportive care.218
Treatment of infections caused by V. vulnificus†.197 250 Optimum anti-infective therapy has not been identified; a tetracycline or third generation cephalosporin (e.g., cefotaxime, ceftazidime) is recommended.197 218 250 Because the case fatality rate associated with V. vulnificus is high, initiate anti-infective therapy promptly if indicated.250 294
Perioperative Prophylaxis
Has been used for perioperative prophylaxis in patients undergoing liver transplantation†; some experts recommend a regimen of cefotaxime and ampicillin for such prophylaxis.169
Has been used for perioperative prophylaxis to reduce the incidence of infection in patients undergoing contaminated or potentially contaminated surgery (e.g., biliary tract, colorectal, other intra-abdominal or GI surgery, genitourinary surgery, abdominal or vaginal hysterectomy) and in patients undergoing cesarean section.169 230 Other anti-infectives (e.g., cefazolin) usually recommended for these procedures.168 169
First or second generation cephalosporins (cefazolin, cefotetan, cefoxitin, cefuroxime) generally preferred when a cephalosporin is used for perioperative prophylaxis.168 169 Third generation cephalosporins (cefotaxime, ceftriaxone, ceftazidime) and fourth generation cephalosporins (cefepime) not usually recommended for perioperative prophylaxis since they are expensive, some are less active against staphylococci than first or second generation cephalosporins, they have wider spectrums of activity than necessary for organisms encountered in elective surgery, and their use for prophylaxis may promote emergence of resistant organisms.168 169

Cefotaxime Dosage and Administration
Administration
Administer by IV injection or infusion or by deep IM injection.230
IV route preferred in patients with septicemia, bacteremia, peritonitis, meningitis, or other severe or life-threatening infections or in patients with lowered resistance resulting from debilitating conditions (e.g., malnutrition, trauma, surgery, diabetes, heart failure, malignancy), particularly if shock is present.230
Large IM doses may be painful; IV administration may be preferred when large doses are indicated.b
Cefotaxime ADD-Vantage vials and the commercially available frozen cefotaxime injection in dextrose should be used only for IV infusion.
For solution and drug compatibility information, see Compatibility under Stability.
IV Injection
Reconstitution
Reconstitute vials containing 500 mg, 1 g, or 2 g of cefotaxime with 10 mL of sterile water for injection to provide solutions containing approximately 50, 95, or 180 mg/mL, respectively.230
Rate of Administration
Inject directly into a vein over a period of 3-5 minutes or slowly into the tubing of a freely flowing compatible IV solution.230
Do not inject IV over <3 minutes; rapid (over <1 minute) injection is associated with potentially life-threatening arrhythmias.230
IV Infusion
Reconstitution and Dilution
Reconstitute infusion bottles containing 1 or 2 g of cefotaxime with 50–100 mL of 0.9% sodium chloride injection or 5% dextrose injection to provide solutions containing 10–20 or 20–40 mg/mL, respectively.230 May be diluted further in 50 mL to 1 L of compatible IV solution.230
Reconstitute 10-g pharmacy bulk package according to the manufacturer’s directions and then dilute further in a compatible IV solution.230
Reconstitute ADD-Vantage vials or infusion bottles containing 1 or 2 g of cefotaxime according to the manufacturer’s directions.230
Thaw the commercially available premixed injection (frozen) at room temperature or in a refrigerator; do not thaw by immersion in a water bath or by exposure to microwave radiation.230 A precipitate may have formed in the frozen injection, but should dissolve with little or no agitation after reaching room temperature.230 Discard thawed injection if an insoluble precipitate is present or if container seals or outlet ports are not intact or leaks are found.230 Do not use in series connections with other plastic containers; such use could result in air embolism from residual air being drawn from the primary container before administration of fluid from the secondary container is complete.230
Rate of Administration
For intermittent IV infusion, infuse over 20–30 minutes via butterfly or scalp vein-type needles.b
During infusion, discontinue other IV solutions flowing through a common administration tubing or site230 unless the solutions are known to be compatible and the flow-rate is adequately controlled.b
IM Injection
Inject IM deeply into a large muscle mass such as the upper outer quadrant of the gluteus maximus.230 Use aspiration to avoid inadvertent injection into a blood vessel.230
2-g IM doses should be divided and administered at 2 different injection sites.230
Reconstitution
Reconstitute vials containing 500 mg, 1 g, or 2 g of cefotaxime with 2, 3, or 5 mL, respectively, of sterile or bacteriostatic water for injection to provide solutions containing approximately 230, 300, or 330 mg/mL, respectively.230

Cautions for Cefotaxime
Contraindications
-
Known hypersensitivity to cefotaxime or other cephalosporins.230
Warnings/Precautions
Warnings
Superinfection/Clostridium difficile-associated Diarrhea and Colitis
Possible emergence and overgrowth of nonsusceptible organisms, especially Enterobacter, Pseudomonas, enterococci, or Candida.230 Careful observation of the patient is essential.230 Institute appropriate therapy if superinfection occurs.230
Treatment with anti-infectives alters normal colon flora and may permit overgrowth of Clostridium difficile.230 342 344 345 C. difficile infection (CDI) and C. difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis) reported with nearly all anti-infectives, including cefotaxime, and may range in severity from mild diarrhea to fatal colitis.230 342 344 345 C. difficile produces toxins A and B which contribute to development of CDAD;230 342 hypertoxin-producing strains of C. difficile are associated with increased morbidity and mortality since they may be refractory to anti-infectives and colectomy may be required.230
Consider CDAD if diarrhea develops during or after therapy and manage accordingly.230 342 344 345 Obtain careful medical history since CDAD may occur as late as 2 months or longer after anti-infective therapy is discontinued.230 342
If CDAD is suspected or confirmed, discontinue anti-infectives not directed against C. difficile whenever possible.230 342 Initiate appropriate supportive therapy (e.g., fluid and electrolyte management, protein supplementation), anti-infective therapy directed against C. difficile (e.g., metronidazole, vancomycin), and surgical evaluation as clinically indicated.230 342 344 345
Cardiac Effects
Potentially life-threatening arrhythmia reported with rapid injection (<1 minute) through a central venous catheter.230 Do not inject IV over <3 minutes.230 (See IV Injection under Dosage and Administration.)
Sensitivity Reactions
Hypersensitivity Reactions
Possible hypersensitivity reactions, including rash (maculopapular or erythematous), pruritus, fever, eosinophilia, urticaria, anaphylaxis, erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis.230
If a hypersensitivity reaction occurs, discontinue cefotaxime and institute appropriate therapy as indicated (e.g., epinephrine, corticosteroids, and maintenance of an adequate airway and oxygen).230
Cross-hypersensitivity
Partial cross-allergenicity among cephalosporins and other β-lactam antibiotics, including penicillins and cephamycins.a
Prior to initiation of therapy, make careful inquiry concerning previous hypersensitivity reactions to cephalosporins, penicillins, or other drugs.230 Cautious use recommended in individuals hypersensitive to penicillins:a avoid use in those who have had an immediate-type (anaphylactic) hypersensitivity reaction and administer with caution in those who have had a delayed-type (e.g., rash, fever, eosinophilia) reaction.a
General Precautions
Selection and Use of Anti-infectives
To reduce development of drug-resistant bacteria and maintain effectiveness of cefotaxime and other antibacterials, use only for treatment or prevention of infections proven or strongly suspected to be caused by susceptible bacteria.230
When selecting or modifying anti-infective therapy, use results of culture and in vitro susceptibility testing.230 In the absence of such data, consider local epidemiology and susceptibility patterns when selecting anti-infectives for empiric therapy.230
History of GI Disease
Use with caution in patients with a history of GI disease, particularly colitis.230 (See Superinfection/Clostridium difficile-associated Diarrhea and Colitis under Cautions.)
Local Effects
May be locally irritating to tissues.230 Inflammation, phlebitis, and thrombophlebitis reported with IV administration;b pain, induration, and tenderness may occur at IM injection sites.230
Perivascular extravasation responds to changing the infusion site;230 extensive perivascular extravasation may result in tissue damage requiring surgery.230
Regularly monitor infusion sites and change site when appropriate.230
Hematologic Effects
Possible transient neutropenia, granulocytopenia, leukopenia, eosinophilia, or thrombocytopenia.230
Agranulocytosis may occur rarely during prolonged therapy.230 Monitor blood cell counts if treatment lasts >10 days.230
CNS Effects
Seizures reported with some cephalosporins, especially in patients with renal impairment who received dosages inappropriate for the degree of renal impairment.230
If seizures occur, discontinue cefotaxime and administer anticonvulsant therapy as indicated.230
Sodium Content
Contains approximately 50.5 mg (2.2 mEq) of sodium per g of cefotaxime.230 366 367
Specific Populations
Pregnancy
Category B.230
Lactation
Distributed into milk; use with caution.230
Pediatric Use
Adverse effects similar to those reported in adults.291
Safety of the chemical components that may leach out of the plastic containing commercially available frozen cefotaxime sodium injections not established.230
Geriatric Use
No overall differences in safety or efficacy in those ≥65 years of age compared with younger adults, but the possibility of increased sensitivity in some geriatric individuals cannot be ruled out.230 366 367
Substantially eliminated by kidneys; risk of toxicity may be greater in those with impaired renal function.230 366 367 Select dosage with caution and consider monitoring renal function because of age-related decreases in renal function.230 366 367 (See Renal Impairment under Dosage and Administration.)
Hepatic Impairment
Possible increased plasma half-life and clearance of cefotaxime and its major metabolite.117 289
Renal Impairment
Plasma half-life of cefotaxime and its major metabolite increased in severe renal impairment.13 16 19 Possibility of seizures if dosage is inappropriately high for the degree of renal impairment.230
Dosage adjustment recommended in those with Clcr <20 mL/minute per 1.73 m3.230
Common Adverse Effects
Local reactions at injection sites, hypersensitivity reactions, GI effects.230

Actions and Spectrum
-
Based on spectrum of activity, classified as a third generation cephalosporin.a Usually less active in vitro against susceptible staphylococci than first generation cephalosporins; has an expanded spectrum of activity against gram-negative bacteria compared with first and second generation cephalosporins.a b
-
Usually bactericidal.a
-
Like other β-lactam antibiotics, antibacterial activity results from inhibition of bacterial cell wall synthesis.230 a
-
Spectrum of activity includes many gram-positive aerobic bacteria, some gram-negative aerobic bacteria, and some anaerobic bacteria; inactive against Chlamydia, fungi, and viruses.a
-
Gram-positive aerobes: active in vitro and in clinical infections against S. pneumoniae, S. pyogenes (group A β-hemolytic streptococci), S. agalactiae (group B streptococci), S. aureus (including β-lactamase-producing strains), and some enterococci (e.g., Enterococcus faecalis).230 a b Also active in vitro against some viridans streptococci.350 Oxacillin-resistant (methicillin-resistant) staphylococci and some enterococci are resistant.a b
-
Gram-negative aerobes: active in vitro and in clinical infections against Acinetobacter, Citrobacter, Enterobacter, E. coli, H. influenzae (including ampicillin-resistant strains), H. parainfluenzae, Klebsiella, M. morganii, N. gonorrhoeae, N. meningitidis, P. mirabilis, P. vulgaris, P. rettgeri, P. stuartii, and Serratia.230 a b Also active in vitro against Campylobacter,222 223 Capnocytophaga,312 314 315 Eikenella corrodens,220 221 249 Moraxella,232 236 240 244 Salmonella,a b Shigella,a b and Vibrio vulnificus.292 Active against some strains of Pseudomonas aeruginosa, but less active against susceptible Ps. aeruginosa than ceftazidime.b
-
Anaerobes and other organisms: active in vitro and in clinical infections against Bacteroides, Eubacterium, Fusobacterium, Peptococcus, Peptostreptococcus, Propionibacterium, Veillonella, and some strains of Clostridium.230 265 a b Also active against the spirochete Borrelia burgdorferi.265
Advice to Patients
-
Advise patients that antibacterials (including cefotaxime) should only be used to treat bacterial infections and not used to treat viral infections (e.g., the common cold).230
-
Importance of completing full course of therapy, even if feeling better after a few days.230
-
Advise patients that skipping doses or not completing the full course of therapy may decrease effectiveness and increase the likelihood that bacteria will develop resistance and will not be treatable with cefotaxime or other antibacterials in the future.230
-
Advise patients that diarrhea is a common problem caused by anti-infectives and usually ends when the drug is discontinued.230 Importance of contacting a clinician if watery and bloody stools (with or without stomach cramps and fever) occur during or as late as 2 months or longer after the last dose.230
-
Importance of informing clinicians if an allergic reaction occurs.230
-
Importance of informing clinicians of existing or contemplated therapy, including prescription and OTC drugs as well as any concomitant illnesses.230
-
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.230
-
Importance of informing patients of other important precautionary information.230 (See Cautions.)
