Drug Levels and Effects

Summary of Use during Lactation

Preliminary information from one mother indicates that apixaban levels in milk are rather high. An alternate drug is preferred, especially while nursing a newborn or preterm infant.[1-3]

Drug Levels

Maternal Levels. A nursing mother who was 23 months postpartum received 2 doses of 5 mg of oral apixaban 12 hours apart. Blood and milk samples were obtained before the first dose and at 3.5, 7, 12 (before the second dose), 16, and 24 hours after the first dose. Peak apixaban milk levels of about 230 mcg/L occurred at 3.5 to 4 hours after each dose. The average milk level over 24 hours was 113.6 mcg/L, which corresponds to a daily infant dosage of 17 mcg/kg daily and a relative infant dose of 12.8% of the maternal weight-adjusted dosage.[3]
