Because absorption from the eye is limited, ketotifen would not be expected to cause any adverse effects in breastfed infants after maternal use of ketotifen 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.
由于眼部吸收有限,预计母亲使用酮替芬滴眼液后不会对母乳喂养的婴儿造成任何不良影响。为了在使用滴眼液后大幅减少进入母乳中的药物量,用眼角按压泪道1分钟或更长时间,然后用吸水纸巾擦去多余的溶液。
