Flunarizine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Flunarizine is not approved for marketing in the United States by the U.S. Food and Drug Administration, but is available in other countries. No information is available on the use of flunarizine during breastfeeding. Because of its long half-life of 19 days in children, expert opinion recommends that flunarizine not be used in migraine prophylaxis.[1][2][3] An alternate drug is preferred, especially while nursing a newborn or preterm infant.
