Summary of Use during Lactation

No relevant published information exists on the use of simvastatin during breastfeeding. Because of a concern with disruption of infant lipid metabolism, the consensus is that simvastatin should not be used during breastfeeding. However, others have argued that children homozygous for familial hypercholesterolemia are treated with statins beginning at 1 year of age, that statins have low oral bioavailability, and risks to the breastfed infant are low, especially with rosuvastatin and pravastatin.[1] Until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
