Frovatriptan Levels and Effects while Breastfeeding
Summary of Use during Lactation
There is no published experience with frovatriptan during breastfeeding. If frovatriptan is required by the mother of an older infant, it is not a reason to discontinue breastfeeding, but until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.[1] Painful, burning nipples and breast pain have been reported after doses of sumatriptan and other triptans. This has occasionally been accompanied by a decrease in milk production.

Effects on Lactation and Breastmilk
A review of four European adverse reaction databases found 26 reported cases of, painful, burning nipples, painful breasts, breast engorgement and/or painful milk ejection in women who took a triptan while nursing. Pain was sometimes intense and occasionally led to decreased milk production. Pain generally subsided with time as the drug was eliminated. The authors proposed that triptans may cause vasoconstriction of the arteries in the breast, nipples, and the arteries surrounding the alveoli and milk ducts, causing a painful sensation and a painful milk ejection reflex.[2]
