Medaxone Contraindications

Hypersensitivity to ceftriaxone, to any other cephalosporin or to any of the excipients listed in Description.
History of severe hypersensitivity (e.g. anaphylactic reaction) to any other type of beta-lactam antibacterial agent (penicillins, monobactams and carbapenems).
Ceftriaxone is contraindicated in: Premature neonates up to a postmenstrual age of 41 weeks (gestational age + chronological age)*.
Full-term neonates (up to 28 days of age): with hyperbilirubinemia, jaundice, or who are hypoalbuminaemic or acidotic because these are conditions in which bilirubin binding is likely to be impaired*; if they require (or are expected to require) intravenous calcium treatment, or calcium-containing infusions due to the risk of precipitation of a ceftriaxone calcium salt (see Precautions, Adverse Reactions and Incompatibilities under Cautions for Usage).
*In vitro studies have shown that ceftriaxone can displace bilirubin from its serum albumin binding sites leading to a possible risk of bilirubin encephalopathy in these patients.
Contraindications to lidocaine must be excluded before intramuscular injection of ceftriaxone when lidocaine solution is used as a solvent (see Precautions).
Ceftriaxone solutions containing lidocaine should never be administered intravenously.
