Summary of Use during Lactation

Although ozanimod and its active metabolites are highly bound in maternal plasma and unlikely to reach the breastmilk in large amounts, it is potentially toxic to the breastfed infant. Because there is no published experience with ozanimod during breastfeeding, expert opinion generally recommends that the closely related drug fingolimod should be avoided during breastfeeding, especially while nursing a newborn or preterm infant.[1-6] Some guidelines recommend avoiding ozanimod during breastfeeding because of a lack of data;[7,8] however, the manufacturer's labeling does not recommend against the use of ozanimod in breastfeeding.
