Drug Levels and Effects

Summary of Use during Lactation

Cannabidiol is a component of cannabis. Cannabidiol has not been studied in nursing women taking the pharmaceutical product, but it has been detected in the breastmilk of some mothers who used cannabis products.[1,2] Because no published information is available with cannabidiol use as an antiepileptic during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Drug Levels

In published reports of anticonvulsant use during breastfeeding, most women were taking a combination of anticonvulsants. Some other anticonvulsants (e.g., phenytoin, carbamazepine) stimulate the metabolism of other drugs including anticonvulsants, whereas others (e.g., valproic acid) inhibit the metabolism of other drugs. Therefore, the relationship of the maternal dosage to the concentration in breastmilk can be quite variable, making calculation of the weight-adjusted percentage of maternal dosage less meaningful than for other drugs in this database.
