Topical betaxolol for ophtalmic use is unlikely to reach a sufficient concentration in the blood in order to harm the infant.

However, when used systemically, betaxolol is excreted in breast milk in significant amounts, so it is preferable to use an alternative medication. It is estimated that administration of 10 mg of betaxolol may produce a concentration in the milk of 48 mcg/L 24 hours after the intake.

An observational study with few patients showed no significant increase in adverse reactions to beta-exposed infants through breast milk.

Warning of the manufacturer:

It is not known whether betaxolol hydrochloride is excreted through the milk. Since many drugs are excreted in human milk, should be cautious when administering to nursing mothers.
