Ceftazim 1 gm/vial IM/IV Injection

The usual adult dosage is 1 gram administered intravenously or intramuscularly every 8 to 12 hours. The dosage and route should be determined by the susceptibility of the causative organisms, the severity of infection and the condition, and renal function of the patient.

Ceftazidime is to be used by the parenteral route, the dosage depending upon the severity, sensitivity & type of infections and the age, weight & renal function of the patient.

Adults: The adult dosage range for ceftazidime is 1 to 6 gm per day 8 or 12 hourly (IM/IV) in the majority of infections, 1 gm 8 hourly or 2 gm 12 hourly should be given.

• In urinary tract infections and many less serious infections: 500 mg or 1 gm 12 hourly is usually adequate.
• In severe infections, especially immunocompromised patients, including those with neutropenia: 2 gm 8 or 12 hourly should be administered. When used as a prophylactic agent in prostatic surgery 1 gm should be given at the induction of anesthesia. A second dose should be considered at the time of catheter removal.

Elderly: In view of the reduced clearance of Ceftazidime in acutely ill elderly patients, the daily dosage should not normally exceed 3 gm, especially in those over 80 years of age.

• Cystic fibrosis: In fibrocystic adults with normal renal function who have pseudomonal lung infections, high doses of 100 to 150 mg/kg/day as three divided doses should be used.

Infants and Children: The usual dosage range for children aged over two months is 30 to 100 mg/kg/day, given as two or three divided doses. Doses up to 150 mg/kg/day (maximum 6 gm daily) in three divided doses may be given to infected immunocompromised or fibrocystic children or children with meningitis.
