Do Antibiotics Pass to Babies Through Breast Milk?
The question of whether antibiotics can pass to infants through breast milk is a significant concern for many breastfeeding mothers. Understanding the implications of antibiotic use during lactation is crucial for both maternal health and infant safety.
Transfer of Antibiotics to Breast Milk
Research indicates that most antibiotics do pass into breast milk to some degree. According to the Academy of American Pediatrics (AAP), antibiotics are among the most commonly prescribed medications for breastfeeding mothers, and while they do transfer into breast milk, the levels are generally low. This means that while some amount of the medication can reach the baby, it is often not enough to cause harm.
However, the extent of this transfer can vary significantly depending on the specific antibiotic. For instance, certain antibiotics like gentamicin and meropenem are poorly absorbed from the gut, which means that even if they are present in breast milk, they are unlikely to be absorbed in sufficient quantities by the infant. This suggests that the risk associated with these medications may be minimal.
Potential Effects on Infants
While many antibiotics are considered safe for breastfeeding mothers and their babies, there are exceptions. Some antibiotics can disrupt an infant’s gastrointestinal flora, potentially leading to issues such as diarrhea or other gastrointestinal disturbances. The impact of antibiotics on the developing gut microbiota of infants is an area of ongoing research, as the composition of gut bacteria plays a crucial role in overall health.
Moreover, the timing of antibiotic administration can also influence the effects on the infant. For example, taking antibiotics just before breastfeeding may result in higher concentrations in the milk at the time of feeding. Therefore, healthcare providers often recommend timing doses to minimize exposure during breastfeeding.
Guidance for Breastfeeding Mothers
For mothers who require antibiotics, the general consensus among health professionals is that breastfeeding should not be interrupted solely due to antibiotic use, unless the specific medication poses a known risk to the infant. Most commonly prescribed antibiotics are deemed safe, and the benefits of breastfeeding—such as providing essential nutrients and antibodies—often outweigh the potential risks associated with antibiotic exposure.
In some cases, healthcare providers may also recommend the use of probiotics alongside antibiotics to help mitigate any negative effects on the infant’s gut microbiota. This approach can support the infant’s health while allowing the mother to continue her necessary treatment.
Conclusion
In summary, while antibiotics do pass into breast milk, the levels are typically low and often not harmful to breastfeeding infants. Mothers should consult with their healthcare providers to ensure they are using safe medications while breastfeeding. The overarching message is one of reassurance: with proper guidance, breastfeeding can continue safely even when antibiotics are necessary for maternal health.

Can a baby be infected through breastfeeding?

There have been a few documented cases of babies acquiring HIV from mothers with undetectable viral loads. PROMISE, an international study of 1200 breastfeeding mothers, found two cases of HIV transmission from mother to infant during breastfeeding when the mothers had an undetectable viral load.

Can antibiotics in breast milk affect babies?

Antibiotic usage is fairly common among breastfeeding mothers and there is potential for transfer to infants through breast milk. While most medicines taken by lactating women cause no harm to their babies, at times it can result in serious consequences.

Can I breastfeed while taking amoxicillin?

Amoxicillin is safe for use in women who are breastfeeding. Its physical characteristics, including low fat solubility, low protein binding, and acidic pH, limit its transfer into breastmilk. The American Academy of Pediatrics considers this drug to be safe to take when breastfeeding.

What illnesses should you not breastfeed?

When Should I Not Breastfeed My Baby?

• If the mother has been infected with HIV or has AIDS.
• Many medications taken by the mother may pass onto the baby via breast milk.
• Mothers with cancer who are taking cancer chemotherapy medications also cannot breastfeed their babies.

Does antibiotics affect newborn?

Neonatal exposure to antibiotics, in the absence of infection, results in abnormal learning and memory in animals and is linked to changes in gut microbes. The relevance of early-life antibiotic exposure to brain function in humans is not known.

What antibiotics are not safe while breastfeeding?

Antibiotics to Avoid While Breastfeeding

• Clindamycin: Clindamycin can sometimes cause mild gastrointestinal (GI) effects like diarrhea, vomiting, diaper rash, or thrush in a breastfed baby2.
• Co-trimoxazole: Rarely prescribed to breastfeeding parents of newborns because of an association with increased jaundice3.

Can I pass infection to my baby through breastfeeding?

Breast milk can occasionally transmit serious viral and bacterial infections to preterm infants. We present three cases of late-onset neonatal sepsis, including one that resulted in death, occurring in preterm infants. The likely source of the microorganisms in all three cases was expressed breast milk.

Do babies get medicine through breast milk?

Although many medications pass into breast milk, most have little or no effect on milk supply or infant well-being. A few medications should be avoided while breastfeeding.

Can antibiotics affect newborn?

Neonatal exposure to antibiotics, in the absence of infection, results in abnormal learning and memory in animals and is linked to changes in gut microbes. The relevance of early-life antibiotic exposure to brain function in humans is not known.

Do antibiotics transfer to a baby?

Many commonly prescribed antibiotics can be transferred from the parent to infant via milk. Commonly prescribed antibiotics used during lactation are summarized in Table 1.
