Precautions for children: Ceftriaxone can displace bilirubin from serum albumin. Newborns with hyperbilirubinemia (especially premature infants) may develop kernicterus. This product should be used with caution or avoided. Precautions for pregnancy and lactation: Reproductive toxicity tests on mice and rats using 20 times the human dose did not show embryotoxicity and teratogenicity. Adequately well-controlled clinical trials have not been conducted in pregnant women. Because animal test results cannot fully reflect human toxicity, pregnant and lactating women should use it only when it is really necessary. Precautions for the elderly: Unless the elderly patient is weak, malnourished, or has severe renal impairment, the recommended adult dose is generally administered without change.
