Levels in milk
Maternal Levels. Twelve healthy women volunteers between 2 an6 6 months postpartum were given a single dose of 75 mg of rimegepant orally. Milk samples from complete emptying of both breasts were obtained 15 to 30 minutes before the dose and 1, 2, 4, 8, 12, 16, 24, 32, and 36 hours after the dose. Peak milk rimegepant levels averaged 169.6 mcg/L at an average of 2 hours after the dose. Average milk levels over the first 24 hours after the dose was 34 mcg/L, which translated into an average daily infant dose of 0.005 mg/kg or a relative infant dose of 0.51%.[ 2 ] Infant Levels.

Alternatives LactMed lists
“No published information” means the studies do not exist yet — not that Rimegepant 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.
