Ticarcillin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Ticarcillin is acceptable to use during breastfeeding. Limited information indicates that maternal doses of ticarcillin up to 15 grams daily produce low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally, disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush, has been reported with penicillins, but these effects have not been adequately evaluated.
Drug Levels
Maternal Levels. Only trace levels of ticarcillin were detected for 6 hours after single 1 gram intramuscular doses in 3 women in one study[1][2] and 5 women in another early study.[3]
After ticarcillin doses of 5 grams intravenously three times a day in 10 women, milk levels averaged 2 to 2.5 mg/L. By 12 hours after the last dose, ticarcillin was undetectable in the milk. The total daily intake of a breastfed infant would be negligible.[4]
