Summary of Use during Lactation

Preliminary evidence indicates that rizatriptan levels in breastmilk are low. Amounts ingested by the infant are small and unlikely to affect the nursing infant, especially if the infant is older than 2 months.

Drug Levels

Maternal Levels. Five women who were at least 1 month postpartum using rizatriptan to treat migraine provided milk samples at intervals over a 24-hour period after a single dose. The authors estimated the weight-adjusted infant dosage to be 0.9% (range 0.3 to 1.4%).[1]
