Small, occasional doses of brompheniramine would not be expected to cause any adverse effects in breastfed infants. 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. Single bedtime doses after the last feeding of the day may be adequate for many women and will minimize any effects of the drug. The nonsedating antihistamines are preferred alternatives.
小剂量、偶尔服用溴苯那敏预计不会对母乳喂养的婴儿产生任何不良影响。较大剂量或更长时间使用可能会对婴儿产生影响或减少乳汁供应，尤其是与拟交感神经药如伪麻黄碱合用时，或在哺乳期尚未完全建立之前。对许多女性来说，每天最后一次喂奶后单次睡前剂量可能就足够了，并且可以将药物的任何影响降至最低。非镇静性抗组胺药是更好的选择。
