Ceftizoxime (Ceftizoxime for injection, USP) is indicated in the treatment of infections due to susceptible strains of the microorganisms listed below.
Lower Respiratory Tract Infections caused by Klebsiella spp.; Proteus mirabills; Escherichia coli; Haemophilus influenzae including ampicillin-resistant strains; Staphylococcus aureus (penicillinase- and nonpenicillinase-producing); Serratia spp.; Enterobacter spp.; Bacteroides spp.; and Streptococcus spp. including S. pneumoniae, but excluding enterococci.
Urinary Tract Infections caused by Staphylococcus aureus (penicillinase- and nonpenicillinase- producing); Escherichia coli; Pseudomonas spp. including P. aeruginosa; Proteus mirabilis; P. vulgaris; Providencia rettgeri (formerly Proteus rettgeri) and Morganella morganii (formerly Proteus morganil); Klebsiella spp.; Serratia spp. including S. marcescens; and Enterobacter spp.
Gonorrhea including uncomplicated cervical and urethral gonorrhea caused by Neisseria gonorrhoeae.
Pelvic Inflammatory Disease caused by Neisseria gonorrhoeae, Escherichia coli or Streptococcus agalactiae. NOTE: Ceftizoxime, like other cephalosporins, has no activity against Chlamydia trachomatis. Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and C. trachomatis is one of the suspected pathogens, appropriate anti-chlamydial coverage should be added.
Intra-Abdominal Infections caused by Escherichia coli; Staphylococcus epidermidis; Streptococcus spp. (excluding enterococci); Enterobacter spp.; Klebsiella spp.; Bacteroides spp. including B. fragilis; and anaerobic cocci, including Peptococcus spp. and Peptostreptococcus spp.
Septicemia caused by Streptococcus spp. including S. pneumoniae (but excluding enterococci); Staphylococcus aureus (penicillinase-and nonpenicillinase-producing); Escherichia coli; Bacteroides spp. including B. fragilis; Klebsiella spp.; and Serratia spp.
Skin and Skin Structure Infections caused by Staphylococcus aureus (penicillinase- and nonpenicillinase-producing); Staphylococcus epidermidis; Escherichia coli; Klebsiella spp.; Streptococcus spp. including Streptococcus pyogenes (but excluding enterococci); Proteus mirabills; Serratia spp.; Enterobacterspp.; Bacteroides spp. including B. fragilis; and anaerobic cocci, including Peptococcus spp. and Peptostreptococcus spp.
Bone and Joint Infections caused by Staphylococcus aureus (penicillinase- and nonpenicillinase-producing); Streptococcus spp. (excluding enterococci); Proteus mirabills; Bacteroides spp.; and anaerobic cocci, including Peptococcus spp. and Peptostreptococcus spp.
Meningitis caused by Haemophilus influenzae. Ceftizoxime (Ceftizoxime) has also been used successfully in the treatment of a limited number of pediatric and adult cases of meningitis caused by Streptococcus pneumoniae.
Ceftizoxime (Ceftizoxime) has been effective in the treatment of seriously ill, compromised patients, including those who were debilitated, immunosuppressed, or neutropenic.
Infections caused by aerobic gram-negative and by mixtures of organisms resistant to other cephalosporins, aminoglycosides, or penicillins have responded to treatment with Ceftizoxime (Ceftizoxime).
Because of the serious nature of some urinary tract infections due to P. aeruginosa and because many strains of Pseudomonas species are only moderately susceptible to Ceftizoxime (Ceftizoxime), higher dosage is recommended. Other therapy should be instituted if the response is not prompt.
Susceptibility studies on specimens obtained prior to therapy should be used to determine the response of causative organisms to Ceftizoxime (Ceftizoxime). Therapy with Ceftizoxime (Ceftizoxime) may be initiated pending results of the studies; however, treatment should be adjusted according to study findings. In serious infections, Ceftizoxime (Ceftizoxime) has been used concomitantly with aminoglycosides. Before using Ceftizoxime (Ceftizoxime) concomitantly with other antibiotics, the prescribing information for those agents should be reviewed for contraindications, warnings, precautions, and adverse reactions. Renal function should be carefully monitored.
Ceftizoxime is in a group of drugs called cephalosporin (SEF a low spor in) antibiotics. It works by fighting bacteria in your body.
Ceftizoxime injection is used to treat many kinds of bacterial infections, including severe or life-threatening forms.
Ceftizoxime may also be used for purposes other than those listed in this medication guide.
The usual adult dosage is 1 or 2 grams of Ceftizoxime (Ceftizoxime for injection, USP) every 8 to 12 hours. Proper dosage and route of administration should be determined by the condition of the patient, severity of the infection, and susceptibility of the causative organisms.
General Guidelines for Dosage of Ceftizoxime (Ceftizoxime) | ||
Uncomplicated Urinary Tract | 1 | 500 mg qi 2h IM or IV |
Other Sites | 2-3 | 1 gram q8-1 2h IM or IV |
Severe or Refractory | 3-6 | 1 gram q8h IM or IV 2 grams q8-12h IMa or IV |
PIDb | 6 | 2 grams q8h IV |
Life-Threateningc | 9-12 | 3-4 grams q8h IV |
a) When administering 2 gram IM doses, the dose should be divided and given in different large muscle masses. b) If C. trachomatis is a suspected pathogen, appropriate antichlamydial coverage should be added, because Ceftizoxime has no activity against this organism. c) In life-threatening infections, dosages up to 2 grams every 4 hours have been given. |
Because of the serious nature of urinary tract infections due to P. aeruginosa and because many strains of Pseudomonas species are only moderately susceptible to Ceftizoxime (Ceftizoxime), higher dosage is recommended. Other therapy should be instituted if the response is not prompt.
A single, 1 gram IM dose is the usual dose for treatment of uncomplicated gonorrhea.
The IV route may be preferable for patients with bacterial septicemia, localized parenchymal abscesses (such as intra-abdominal abscess), peritonitis, or other severe or life-threatening infections.
In those with normal renal function, the IV dosage for such infections is 2 to 12 grams of Ceftizoxime (Ceftizoxime for injection, USP) daily. In conditions such as bacterial septicemia, 6 to 12 grams/day may be given initially by the IV route for several days, and the dosage may then be gradually reduced according to clinical response and laboratory findings.
Pediatric Dosage Schedule | ||
Unit Dose | Frequency | |
Pediatric patients 6 months or older | 50 mg/kg | q6-8h |
Dosage maybe increased to atotal daily dose of 200 mg/kg (not to exceed the maximum adult dose for serious infection).
Impaired Renal Function
Modification of Ceftizoxime (Ceftizoxime) dosage is necessary in patients with impaired renal function. Following an initial loading dose of 500 mg-1 gram IM or IV, the maintenance dosing schedule shown below should be followed. Further dosing should be determined by therapeutic monitoring, severity of the infection, and susceptibility of the causative organisms.
When only the serum creatinine level is available, creatinine clearance may be calculated from the following formula. The serum creatinine level should represent current renal function at the steady state.
Males:
Clcr † | Weight (kg) x (140 - age) cr † 72 x serum creatinine ________________________________________ (mg/100 mL) |
Females: Females are 0.85 of the calculated clearance values for males.
In patients undergoing hemodialysis, no additional supplemental dosing is required following hemodialysis; however, dosing should be timed so that the patient receives the dose (according to the table below) at the end of the dialysis.
Dosage in Adults with Reduced Renal Function | |||
Creatinine Clearance mL/min | Renal Function | Less Severe Infections | Life-Threatening Infections |
79-50 | Mild impairment | 500 mg q8h | 0.75-1.5 grams q8h |
49-5 | Moderate to severe impairment | 250-500 mg ql2h | 0.5-1 gram ql2h |
4-0 | Dialysis patients | 500 mg q48h or 250 mgq24h | 0.5-1 gram q48h or 0.5 gram q24h |

What is the most important information I should know about Ceftizoxime?
Ceftizoxime for Injection USP and Dextrose Injection USP is contraindicated in patients with known allergy to the cephalosporin group of antibiotics. Solutions containing dextrose may be contraindicated in patients with hypersensitivity to corn products.
Use Ceftizoxime as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Ceftizoxime is usually administered as an injection at your doctor's office, hospital, or clinic.
- If you are using Ceftizoxime at home, carefully follow the injection procedures taught to you by your health care provider.
- If the medicine contains particles or is discolored, or if the vial/container is cracked or damaged in any way, do not use it.
- Ceftizoxime works best when taken at the same time(s) each day.
- To clear up your infection completely, continue using Ceftizoxime for the full course of treatment even if you feel better in a few days. Do not miss any doses.
- Do not reuse needles, syringes, or other materials. Dispose of properly after use. Ask your doctor, nurse, or pharmacist to explain local regulations for selecting an appropriate container and properly disposing of the container when full.
- If you miss a dose of Ceftizoxime, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Ceftizoxime.
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.Ceftizoxime is used to treat lower respiratory tract infections, urinary tract infections, gonorrhea and pelvic inflammatory disease.
