Ceftriaxone Pregnancy |
||
Ceftriaxone crosses the placenta. Pregnancy was found to influence the single dose pharmacokinetics of Ceftriaxone when administered prior to delivery (Popović 2007). The pharmacokinetics of Ceftriaxone following multiple doses in the third trimester are similar to those of nonpregnant patients (Bourget 1993). Ceftriaxone is recommended for use in pregnant women for the treatment of gonococcal infections, Lyme disease, and may be used in certain situations prior to vaginal delivery in women at high risk for endocarditis (consult current guidelines) (ACOG 120, 2011; CDC [Workowski 2015]; Wormser 2006).
Use is considered acceptable; caution is recommended. -UK: A decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother and the benefit of breastfeeding for the child. Excreted into human milk: Yes (small amounts) Comments: -The effects in the nursing infant are unknown; low levels in milk not expected to cause harmful effects in the nursing infant. -This drug is considered compatible with breastfeeding by the American Academy of Pediatrics.
After 1 g IM or IV on day 3 postpartum to 20 women, peak milk levels averaged about 0.7 and 0.5 mg/L, respectively, at about 4 hours after the dose. Levels decreased very slowly over 24 hours with half-lives of 13 to 17 hours. Amounts in milk correspond to infant dose of about 0.5% of the maternal weight-adjusted dose. With usual doses, only a few mg of this drug expected to be ingested per day by the infant. Disruption of infant's gastrointestinal flora (resulting in diarrhea or thrush) reported occasionally with cephalosporins; such effects have not been adequately evaluated. Risk of diarrhea and mucous membrane fungal infections cannot be excluded; possible sensitization should be considered.
