ceftriaxone use in third trimester pregnancy safety neonatal hyperbilirubinemia near term

Yes. Ceftriaxone 1 g is generally considered safe in the third trimester (8 months), as long as there is a proper indication.
Safety
  • Textbooks describe cephalosporins as safe in pregnancy, including ceftriaxone. Rosen's Emergency Medicine says first- to fourth-generation cephalosporins "appear to be safe during pregnancy, although there have been no controlled studies." Sabiston's says most are not associated with any known or suspected teratogenic effects.
  • Ceftriaxone is the preferred or recommended agent in pregnancy for several infections:
    • Gonorrhoea, as a 500 mg IM single dose (Creasy & Resnik's Maternal-Fetal Medicine).
    • Meningococcal prophylaxis, 250 mg IM, preferred in pregnancy (Washington Manual).
    • Pyelonephritis in pregnant women (Brenner & Rector's The Kidney).
  • Penicillins and cephalosporins were formerly FDA category B (Dermatology, 5e).
  • Animal studies show no teratogenicity or fetotoxicity. Human data are limited to observational reports and no controlled trials, so use it only when there is a clear indication.
Dose
  • 1 g once daily, IV or IM, is a standard adult dose and needs no adjustment in pregnancy. Pharmacokinetics are similar to non-pregnant adults, and the drug does not accumulate.
  • The dose and duration depend on the infection. Severe infections such as pyelonephritis, chorioamnionitis or sepsis may need 1 to 2 g daily.
Points to watch near term (8 months)
  • Neonatal jaundice: Ceftriaxone is highly albumin-bound and can displace bilirubin in vitro. The risk is mainly for jaundiced or premature neonates who are given the drug directly. Giving it to the mother a few days before delivery is not considered a contraindication, and kernicterus from this has not been reported. Tell the paediatric team if the mother received it close to delivery.
  • Breastfeeding: Only small amounts pass into milk. It is generally compatible with breastfeeding, though the infant's stool and rash should be watched.
  • Calcium: Do not mix or co-infuse it with calcium-containing IV fluids such as Ringer's lactate. This matters mostly for neonates, but it is good practice for everyone.
  • Allergy: Check for penicillin or cephalosporin allergy before giving it.
  • Biliary sludge: This can occur with prolonged use or high doses. It is usually reversible.
  • IM injection: If you give it IM, dilute it with 1% lignocaine, which is for IM use only and never IV.
When to avoid it
  • Known hypersensitivity (anaphylaxis) to ceftriaxone or other cephalosporins.
  • No clear indication. Avoid unnecessary antibiotics.
A recent PubMed check (last 2 years, systematic reviews and meta-analyses) found nothing that changes this.
Please confirm the indication and the dose with the treating obstetrician, particularly if you are taking this yourself rather than prescribing it.
