Fortum is indicated for the treatment of the infections listed below in adults and children including neonates (from birth).
Treatment of patients with bacteraemia that occurs in association with, or is suspected to be associated with, any of the infections listed above.
Ceftazidime may be used in the management of neutropenic patients with fever that is suspected to be due to a bacterial infection.
Ceftazidime may be used in the peri-operative prophylaxis of urinary tract infections for patients undergoing transurethral resection of the prostate (TURP).
The selection of ceftazidime should take into account its antibacterial spectrum, which is mainly restricted to aerobic Gram negative bacteria (see sections 4.4 and 5.1).
Ceftazidime should be co-administered with other antibacterial agents whenever the possible range of causive bacteria would not fall within its spectrum of activity.
Consideration should be given to official guidelines on the appropriate use of antibacterial agents.

1 In neonates and infants ≤ 2 months, the serum half life of ceftazidime can be three to four times that in adults.
* Where associated with, or suspects to be associated with, any of the infections listed in section 4.1.
The safety and efficacy of Fortum administered as continuous infusion to neonates and infants ≤2 months has not been established.
In view of the age related reduced clearance of ceftazidime in elderly patients, the daily dose should not normally exceed 3 g in those over 80 years of age.
Available data do not indicate the need for dose adjustment in mild or moderate liver function impairment. There are no study data in patients with severe hepatic impairment (see also section 5.2). Close clinical monitoring for safety and efficacy is advised.
Ceftazidime is excreted unchanged by the kidneys. Therefore, in patients with impaired renal function, the dosage should be reduced (see also section 4.4).
An initial loading dose of 1 g should be given. Maintenance doses should be based on creatinine clearance:
Table 3. Recommended maintenance doses of Fortum in renal impairment – intermittent infusion:
Adults and children ≥40 kg:
Creatinine clearance Ml/min | Approx. serum creatinine µmol/l(mg/dl) | Recommended unit dose of Fortum (g) | Frequency of dosing (hourly) |
---|---|---|---|
50-31 | 150-200 (1.7-2.3) | 1 | 12 |
30-16 | 200-350 (2.3-4.0) | 1 | 24 |
15-6 | 350-500 (4.0-5.6) | 0.5 | 24 |
<5 | >500 (>5.6) | 0.5 | 48 |
In patients with severe infections the unit dose should be increased by 50% or the dosing frequency increased. In children the creatinine clearance should be adjusted for body surface area or lean body mass.
Children <40 kg:
Creatinine clearance (ml/min)** | Approx. serum creatinine* µmol/l (mg/dl) | Recommended individual dose mg/kg body weight | Frequency of dosing (hourly) |
---|---|---|---|
50-31 | 150-200 (1.7-2.3) | 25 | 12 |
30-16 | 200-350 (2.3-4.0) | 25 | 24 |
15-6 | 350-500 (4.0-5.6) | 12.5 | 24 |
<5 | >500 (>5.6) | 12.5 | 48 |
* The serum creatinine values are guideline values that may not indicate exactly the same degree of reduction for all patients with reduced renal function.
** Estimated based on body surface area, or measured.
Close clinical monitoring for safety and efficacy is advised.
Table 4. Recommended maintenance doses of Fortum in renal impairment – continuous infusion:
Adults and children ≥40 kg:
Creatinine clearance (ml/min) | Approx. Serum creatinine µmol/l (mg/dl) | Frequency of dosing (hourly) |
---|---|---|
50-31 | 150-200 (1.7-2.3) | Loading dose of 2 g followed by 1 g to 3 g /24 hours |
30-16 | 200-350 (2.3-4.0) | Loading dose of 2 g followed by 1 g /24 hours |
≤15 | >350 (>4.0) | Not evaluated |
Caution is advised in dose selection. Close clinical monitoring for safety and efficacy is advised.
Children <40 kg:
The safety and effectiveness of Fortum administered as continuous infusion in renally impaired children <40 kg has not been established, Close clinical monitoring for safety and efficacy is advised.
If continuous infusion is used in children with renal impairment, the creatinine clearance should be adjusted for body surface area or lean body mass.
The serum half-life during haemodialysis ranges from 3 to 5 h.
Following each haemodialysis period, the maintenance dose of ceftazidime recommended in the tables 5 & 6 should be repeated.
Ceftazidime may be used in peritoneal dialysis and continuous ambulatory peritoneal dialysis (CAPD).
In addition to intravenous use, ceftazidime can be incorporated into the dialysis fluid (usually 125 to 250mg for 2 litres of dialysis solution).
For patients in renal failure on continuous arterio-venous haemodialysis or high-flux haemofiltration in intensive therapy units: 1 g daily either as a single dose or in divided doses. For low-flux haemofiltration, follow the dose recommended under renal impairment.
For patients on veno-venous haemofiltration and veno-venous haemodialysis, follow the dosage recommendations in tables 5 & 6 below.

Residual renal function (creatinine clearance ml/min) | Maintenance dose (mg) for an ultrafiltration rate (ml/min) of1: | |||

1 Maintenance dose to be administered every 12 h.
The dose depends on the severity, susceptibility, site and type of infection and on the age and renal function of the patient.
Fortum 1 g should be administered by intravenous injection or infusion, or by deep intramuscular injection. Recommended intramuscular injection sites are the upper outer quadrant of the gluteus maximus or lateral part of the thigh. Fortum solutions may be given directly into the vein or introduced into the tubing of a giving set if the patient is receiving parenteral fluids. The standard recommended route of administration is by intravenous intermittent injection or intravenous continuous infusion. Intramuscular administration should only be considered when the intravenous route is not possible or less appropriate for the patient.
Overdose can lead to neurological sequelae including encephalopathy, convulsions and coma.
Symptoms of overdose can occur if the dose is not reduced appropriately in patients with renal impairment (see sections 4.2 and 4.4)
Serum levels of ceftazidime can be reduced by haemodialysis or peritoneal dialysis.

After reconstitution:
Chemical and physical in-use stability has been demonstrated for 6 days at 4°C and 9 hours at 25°C.
From a microbiological point of view, the reconstituted solution should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C, unless reconstitution has taken place in controlled and validated aseptic conditions.
After dilution:
Chemical and physical in-use stability has been demonstrated for 6 days at 4°C and 9 hours at 25°C.
From a microbiological point of view, the reconstituted and diluted solution should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C, unless reconstitution has taken place in controlled and validated aseptic conditions.
Store below 25°C.
Keep vials in the outer carton to protect from light.
For storage conditions after reconstitution see section 6.3.
Fortum 1 g powder for solution for injection or infusion is packaged in clear Ph.Eur.Type III glass 17 ml, 26 ml, 60 ml or 77 ml vial with a bromobutyl rubber plug and a flip-off type aluminium overseal.
