Hypersensitivity to the active substance, to any other cephalosporin or to any of the excipients listed in section 6.1.
History of severe hypersensitivity (e.g. anaphylactic reaction) to any other type of beta-lactam antibacterial agent (penicillins, monobactams and carbapenems).
As with all beta-lactam antibacterial agents, serious and occasionally fatal hypersensitivity reactions have been reported. In case of severe hypersensitivity reactions, treatment with ceftazidime must be discontinued immediately and adequate emergency measures must be initiated.
Before beginning treatment, it should be established whether the patient has a history of severe hypersensitivity reactions to ceftazidime, to other cephalosporins or to any other type of beta-lactam agent. Caution should be used if ceftazidime is given to patients with a history of non-severe hypersensitivity to other beta-lactam agents.
Ceftazidime has a limited spectrum of antibacterial activity. It is not suitable for use as a single agent for the treatment of some types of infections unless the pathogen is already documented and known to be susceptible or there is a very high suspicion that the most likely pathogen(s) would be suitable for treatment with ceftazidime. This particularly applies when considering the treatment of patients with bacteraemia and when treating bacterial meningitis, skin and soft tissue infections and bone and joint infections. In addition, ceftazidime is susceptible to hydrolysis by several of the extended spectrum beta lactamases (ESBLs). Therefore information on the prevalence of ESBL producing organisms should be taken into account when selecting ceftazidime for treatment.
Antibacterial agent-associated colitis and pseudo-membranous colitis have been reported with nearly all anti-bacterial agents, including ceftazidime, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhoea during or subsequent to the administration of ceftazidime (see section 4.8). Discontinuation of therapy with ceftazidime and the administration of specific treatment for Clostridium difficile should be considered. Medicinal products that inhibit peristalsis should not be given.
Concurrent treatment with high doses of cephalosporins and nephrotoxic medicinal products such as aminoglycosides or potent diuretics (e.g. furosemide) may adversely affect renal function.
Ceftazidime is eliminated via the kidneys, therefore the dose should be reduced according to the degree of renal impairment. Patients with renal impairment should be closely monitored for both safety and efficacy. Neurological sequelae have occasionally been reported when the dose has not been reduced in patients with renal impairment (see sections 4.2 and 4.8).
Prolonged use may result in the overgrowth of non-susceptible organisms (e.g. Enterococci, fungi) which may require interruption of treatment or other appropriate measures. Repeated evaluation of the patient’s condition is essential.
Ceftazidime does not interfere with enzyme-based tests for glycosuria, but slight interference (false-positive) may occur with copper reduction methods (Benedict’s, Fehling’s, Clinitest).
Ceftazidime does not interfere in the alkaline picrate assay for creatinine.
The development of a positive Coombs' test associated with the use of ceftazidime in about 5% of patients may interfere with the cross-matching of blood.
Important information about one of the ingredients of Ceftazidime:
1 g powder for solution for injection or infusion, 1 g powder for solution for infusion
Ceftazidime 1 g contains 2.26mmol of sodium per vial.
This should be considered for patients who are on a controlled sodium diet.
Interaction studies have only been conducted with probenecid and furosemide.
Concurrent use of high doses with nephrotoxic medicinal products may adversely affect renal function (see section 4.4).
Chloramphenicol is antagonistic in vitro with Ceftazidime and other cephalosporins. The clinical relevance of this finding is unknown, but if concurrent administration of ceftazidime with chloramphenicol is proposed, the possibility of antagonism should be considered.
There are limited amounts of data from the use of ceftazidime in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy embryonal/foetal development, parturition or postnatal development (see section 5.3).
Ceftazidime should be prescribed to pregnant woman only if the benefit outweighs the risk.
Ceftazidime is excreted in human milk in small quantities but at therapeutic doses of ceftazidime no effects on the breast-fed infant are anticipated. Ceftazidime can be used during breast-feeding.
No data are available.
No studies on the effects on the ability to drive and use machines have been performed. However, undesirable effects may occur (e.g. dizziness), which may influence the ability to drive and use machines (see section 4.8).
The most common adverse reactions are eosinophilia, thrombocytosis, phlebitis or thrombophlebitis with intravenous administration, diarrhoea, transient increases in hepatic enzymes, maculopapular or urticarcial rash, pain and/or inflammation following intramuscular injection and positive Coomb’s test.
Data from sponsored and un-sponsored clinical trials have been used to determine the frequency of common and uncommon undesirable effects. The frequencies assigned to all other undesirable effects were mainly determined using post-marketing data and refer to a reporting rate rather than a true frequency. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness. The following convention has been used for the classification of frequency:
Very common (≥1/10)
Common (≥1/100 to <1/10)
Uncommon (≥1/1,000 to <1/100)
Rare (≥1/10,000 to <1/1,000)
Very rare (<1/10,000)
Unknown (cannot be estimated from the available data)
Uncommon: Candidiasis (including vaginitis and oral thrush)
Common: Eosinophilia, Thrombocytosis
Uncommon: Neutropenia, Leucopenia, Thrombocytopenia
Unknown: Agranulocytosis, Haemolytic anaemia, Lymphocytosis
Unknown: Anaphylaxis (including bronchospasm and/or hypotension) (see section 4.4)
Uncommon: Headache, Dizziness
Unknown: Neurological sequelae1, Paraesthesia
Common: Phlebitis or thrombophlebitis with intravenous administration
Common: Diarrhoea
Uncommon: Antibacterial agent-associated diarrhoea and colitis2 (see section 4.4), Abdominal pain, Nausea, Vomiting
Unknown: Bad taste
Common: Transient elevations in one or more hepatic enzymes3
Unknown: Jaundice
Common: Maculopapular or urticarial rash
Uncommon: Pruritus
Unknown: Toxic epidermal necrolysis, Stevens-johnson syndrome, Erythema multiforme, Angioedema, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)4
Uncommon: Transient elevations of blood urea, blood urea nitrogen and/or serum creatinine
Very rare: Interstitial nephritis, Acute renal failure
Common: Pain and/or inflammation after intramuscular injection
Uncommon: Fever
Common: Positive Coombs' test5
1 There have been reports of neurological sequelae including tremor, myoclonia, convulsions, encephalopathy and coma in patients with renal impairment in whom the dose of Ceftazidime has not been appropriately reduced.
2 Diarrhoea and colitis may be associated with Clostridium difficile and may present as pseudomembranous colitis.
3 ALT (SGPT), AST (SOGT), LHD, GGT, alkaline phosphatase.
4 There have been rare reports where DRESS has been associated with ceftazidime.
5 A positive Coombs test develops in about 5% of patients and may interfere with blood cross matching.
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
n the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products.
Ceftazidime is less stable in Sodium Bicarbonate Injection than other intravenous fluids. It is not recommended as a diluent.
Ceftazidime and aminoglycosides should not be mixed in the same giving set or syringe.
Precipitation has been reported when vancomycin has been added to ceftazidime in solution. Therefore, it would be prudent to flush giving sets and intravenous lines between administration of these two agents.
Ceftazidime is incompatible with aminophylline. There is a possible incompatibility with pentamide.
