In animal reproduction studies, continuous infusion of cangrelor in pregnant rats and rabbits throughout organogenesis at dose approximately 2-times the maximum recommended human dose (MRHD) did not result in fetal malformations.

Cangrelor use during labor and delivery may increase the risk for maternal bleeding and hemorrhage. Performance of neuraxial blockade procedures is not advised during cangrelor use due to the potential risk of spinal hematoma. When possible, discontinue cangrelor 1 hour prior to labor, delivery, or neuraxial blockade.

There are no data on the presence of cangrelor in human milk or animal milk, its effects on breastfed infants, or on milk production. Due to its short-half life, cangrelor exposure is expected to be very low in breastfed infant. Consult your doctor.
