Is Ubrogepant safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Ubrogepant. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
No information is available on the clinical use of ubrogepant during breastfeeding. However, amounts in breastmilk are low and virtually absent from milk 16 hours after a dose. Ubrogepant is not expected to cause any adverse effects in breastfed infants. If ubrogepant 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 while nursing a newborn or preterm infant. Some experts recommend withholding breastfeeding for 8 to 12 hours after a dose.[1]

Levels in milk
Maternal Levels. Twelve lactating women who were 1 to 6 months postpartum received a single dose of 100 mg of ubrogepant orally. Breastmilk was expressed completely from both breasts using an electric pump and collected at 0 to 2, 2 to 4, 4 to 8, 8 to 12, 12 to 16, and 16 to 24 hours after the dose. The peak concentration in milk was 384 mcg/L in the 0 to 2 hour sample, which was designated as 1 hour. The concentrations of ubrogepant in breast milk were <1 mcg/L in the collection at 16 to 24 hours after the dose in 10 of the 12 participants. The cumulative amount of ubrogepant recovered in breast milk over 24 hour after the dose was 0.014 mg and the mean relative infant dose was 0.15%.[2]

Alternatives LactMed lists
“No published information” means the studies do not exist yet — not that Ubrogepant is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
