The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
The usual adult dosage is 1 or 2 grams of Cefizox (ceftizoxime injection) in Galaxy® plastic container 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.

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 Cefizox, 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 intraabdominal abscess), peritonitis, or other severe or lifethreatening infections.
In those with normal renal function, the IV dosage for such infections is 2 to 12 grams of Cefizox (ceftizoxime injection) 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 patients6 months or older
Dosage may be increased to a total daily dose of 200 mg/kg (not to exceed the maximum adult dose for serious infection).
Impaired Renal Function
Modification of Cefizox dosage is necessary in patients with impaired renal function. Following an initial loading dose of 500 mg-1 gram 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.
Clcr =Weight (kg) x (140 age)
72 x serum creatinine
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.
