Clavulanate / ticarcillin Breastfeeding Warnings

Use is considered acceptable; caution is recommended and benefit should outweigh risk.

Excreted into human milk: Yes (ticarcillin in small amounts); No (clavulanate)

Comments:
-Low levels in milk are not expected to cause harmful effects in the nursing infant; according to some authorities, risk of sensitization/hypersensitivity reactions should be considered.
-Disruption of infant's gastrointestinal flora (resulting in diarrhea or thrush) reported occasionally with penicillins, but such effects have not been adequately evaluated.
-Ticarcillin is considered compatible with breastfeeding by the American Academy of Pediatrics.

After single 1 g IM doses of ticarcillin in 3 women in 1 study and 5 women in another early study, only trace amounts were detected for 6 hours.

After ticarcillin 5 g IV 3 times a day in 10 women, milk levels averaged 2 to 2.5 mg/L; ticarcillin was undetectable in milk by 12 hours after last dose. Total daily intake of a breastfed infant would be negligible.
