| The most frequently reported adverse events for ceftriaxone are diarrhoea, nausea and vomiting. Other reported adverse events include hypersensitivity reactions such as allergic skin reactions and anaphylactic reactions, secondary infections with yeast, fungi or resistant organisms as well as changes in blood cell counts.Rarely, severe, and in some cases fatal, adverse reactions have been reported in preterm and full-term newborns (aged <28 days) who had been treated with intravenous ceftriaxone and calcium. Precipitations of ceftriaxone-calcium salt have been observed in lung and kidneys post-mortem. The high risk of precipitation in newborns is due to their low blood volume and the longer half life of ceftriaxone compared with adults (see sections 4.3, 4.4 and 5.2). Infections and infestations Rare ( 0.01% - < 0.1%): Mycosis of the genital tract.Superinfections of various sites with yeasts, fungi or other resistant organisms are possible.Blood and lymphatic system disorders Rare ( 0.01% - < 0.1%): Neutropenia, leucopenia, eosinophilia, thrombocytopenia, anaemia (including haemolytic anaemia), slight prolongation of prothrombin time.Very rare (< 0.01 %) including isolated reports: Positive Coombs' test, coagulation disorders, agranulocytosis (< 500/m3), mostly after 10 days of treatment and following total doses of 20g ceftriaxone and more.Immune system disorders Rare ( 0.01% - < 0.1%): Anaphylactic (e.g. bronchospasm) and anaphylactoid reactions (see section 4.4)Nervous system disorders Rare ( 0.01% - < 0.1%): Headache, dizziness.Gastrointestinal disorders Common ( 1% - < 10%): Loose stools or diarrhoea, nausea, vomiting.Rare ( 0.01% - < 0.1%): Stomatitis, glossitis. These side effects are usually mild and commonly disappear during treatment or after discontinuation of treatment.Very rare (< 0.01%) including isolated reports: Pseudomembranous colitis (mostly caused by Clostridium difficile), pancreatitis (possibly caused by obstruction of bile ducts). Therefore, the possibility of the disease should be considered in patients who present with diarrhoea following antibacterial agent use.Hepato-biliary disorders Rare ( 0.01% - < 0.1%): Increase in serum liver enzymes (AST, ALT, alkaline phosphatase). Precipitation of ceftriaxone calcium salt in the gallbladder has been observed (see section 4.4), mostly in patients treated with doses higher than the recommended standard dose. In children, prospective studies have shown a variable incidence of precipitation with intravenous application, in some studies to above 30 %. The incidence seems to be lower with slow infusion (20-30 minutes). This effect is usually asymptomatic, but in rare cases, the precipitations have been accompanied by clinical symptoms such as pain, nausea and vomiting. Symptomatic treatment is recommended in these cases. Precipitation is usually reversible upon discontinuation of ceftriaxone.Skin and subcutaneous tissue disorders Uncommon ( 0.1% - < 1%): Allergic skin reactions such as maculopapular rash or exanthema, urticaria, dermatitis, pruritus, oedema. Very rare (< 0.01%) including isolated reports: Erythema multiforme, Stevens Johnson Syndrome, Lyell's Syndrome/toxic epidermal necrolysis.Renal and urinary disorders Rare ( 0.01% - < 0.1%): Increase in serum creatinine, oliguria, glycosuria, haematuria. Very rare (< 0.01%) including isolated reports: Renal precipitation, mostly in children older than 3 years who have been treated with either high daily doses (80 mg/kg/day and more) or total doses exceeding 10g and with other risk factors such as dehydration or immobilisation. Renal precipitation is reversible upon discontinuation of ceftriaxone. Anuria and renal impairment have been reported in association. General disorders and administration site conditions Rare ( 0.01% - < 0.1%): Phlebitis and injection site pain following intravenous administration. This can be minimised by slow injection over at least 2-4 minutes. Rigors, pyrexia.An intramuscular injection without lidocaine solution is painful. | |
