• A safety Score of 5 indicates that usage of Acebutololo may cause serious side effects in breastfed baby.
• Our study of different scientific research indicates that Acebutololo may cause moderate to high side effects or may affect milk supply in lactating mother.
• Our suggestion is to use safer alternate options rather than using Acebutololo .
• It is recommended to evaluate the advantage of not breastfeeding while using Acebutololo Vs not using Acebutololo And continue breastfeeding.
• While using Acebutololo Its must to monitor child for possible reactions. It is also important to understand that side effects vary largely based on age of breastfed child and time of medication in addition to dosage.

Drug is secreted in high amount into breast milk. Several cases have been published that did not report side effects in nursing babies, however, hypotension, bradicardia and tachypnea were found in one newborn.

Because of the relatively extensive excretion of Acebutololo and its active metabolite diacetolol into breastmilk and their extensive renal excretion, other agents may be preferred, especially while nursing a newborn or preterm infant.[1][2][3]

A study of mothers taking beta-blockers during nursing found a numerically, but not statistically significant increased number of adverse reactions in those taking any beta-blocker. Although the ages of infants were matched to control infants, the ages of the affected infants were not stated. One mother reported no adverse effects in her breastfed infant (age unstated) during Acebutololo use.[8] Hypotension, bradycardia, and transient tachypnea occurred in a newborn infant, probably because of Acebutololo and diacetolol in breastmilk. The mother was taking 400 mg/day of Acebutololo and had renal impairment. Two other neonates in this report who were breastfed had no adverse reactions noted.[1]

Relevant published information on the effects of beta-blockade or Acebutololo during normal lactation was not found as of the revision date. A study in 6 patients with hyperprolactinemia and galactorrhea found no changes in serum prolactin levels following beta-adrenergic blockade with propranolol.[9]
