Hypersensitivity reactions
As with all antibacterial beta-lactam drugs, there have been serious and occasionally fatal hypersensitivity reactions. In the event of hypersensitivity reactions, administration of ceftriaxone should be stopped at once and appropriate emergency therapy should be initiated.
Immune-mediated haemolytic anaemia Immune-mediated hemolytic anemia has been reported in patients on cephalosporin-class antibacterials such as ceftriaxone. The cases of hemolytic anemia, including fatalities, have occurred during treatment with ceftriaxone in adults and children.
Antibacterial spectrum Ceftriaxone has a limited spectrum of antibacterial activity and may not be suitable for use as a single agent for the treatment of some types of infections unless the pathogen has already been confirmed.
Renal lithiasis
Renal lithiasis cases have been observed, which are reversible if ceftriaxone is discontinued.
Jarisch-Herxheimer reaction (JHR)
It may cause a Jarisch-Herxheimer reaction (JHR) in some patients with spirochete infection shortly after initiating ceftriaxone therapy. JHR is a self-limiting condition in most instances or can be treated symptomatically. The antibiotic therapy must not be stopped if such a reaction does take place.
Encephalopathy
Encephalopathy has been associated with the administration of ceftriaxone, especially in older patients with serious renal impairment or central nervous system disease.
Store below 30°C. Protect from light and moisture. Keep the medicine out of reach of children.
