Pemirolast is no longer marketed in the United States. Although no published data exist on the use of pemirolast during lactation, maternal milk levels are likely to be very low after the use eye drops. To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue.
在美国，吡嘧司特已不再销售。虽然目前尚无关于哺乳期使用吡嘧司特的公开数据，但使用滴眼液后母乳中的药物水平可能非常低。为了在使用滴眼液后大幅减少进入母乳中的药物量，可在眼角处按压泪道1分钟或更长时间，然后用吸水纸巾擦去多余的溶液。
