The product information does not recommend prasugrel during breastfeeding because human milk data are unavailable. UK specialist guidance considers cautious use possible after an individual assessment for a full-term, healthy infant, with monitoring for skin reactions, bruising or prolonged bleeding; seek specialist advice for premature or unwell infants.
