Tygacil Use In Pregnancy & Lactation



Full Prescribing Info
Use In Pregnancy & Lactation
Use in pregnancy: Pregnancy Category C: Tigecycline may cause fetal harm when administered to a pregnant woman. Results of animal studies indicate that tigecycline crosses the placenta and is found in fetal tissues. Decreased fetal weights in rats and rabbits (with associated delays in ossification) and fetal loss in rabbits have been observed with tigecycline.
Tigecycline was not teratogenic in the rat or rabbit. In preclinical safety studies, 14C-labeled tigecycline crossed the placenta and was found in fetal tissues, including fetal bony structures. The administration of tigecycline was associated with slight reductions in fetal weights and an increased incidence of minor skeletal anomalies (delays in bone ossification) at exposures of 4.7 and 1.1 times the human daily dose based on AUC in rats and rabbits, respectively. An increased incidence of fetal loss was observed at exposures of 1.1 times the human daily dose based on AUC in rabbits, at dosages producing minimal maternal toxicity.
There are no adequate and well-controlled studies of tigecycline in pregnant women. Tygacil should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus (see Warnings).
Labor and Delivery: Tygacil has not been studied for use during labor and delivery.
Use in lactation: Results from animal studies using 14C-labeled tigecycline indicate that tigecycline is excreted readily via the milk of lactating rats. Consistent with the limited oral bioavailability of tigecycline, there is little or no systemic exposure to tigecycline in nursing pups as a result of exposure via maternal milk.
It is not known whether Tygacil is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Tygacil is administered to a nursing woman. (See Warnings.)
