Small, occasional doses of pyrilamine are probably acceptable during breast feeding. Larger doses or more prolonged use may cause effects in the infant or decrease the milk supply, particularly, in combination with a sympathomimetic such as pseudoephedrine or before lactation is well established. The nonsedating antihistamines are preferred alternatives.
