Can Drugs Be Excreted in Breast Milk?
The question of whether drugs can be excreted in breast milk is a significant concern for nursing mothers who may require medication. Understanding the dynamics of drug transfer into breast milk is crucial for ensuring both maternal health and infant safety.
Mechanisms of Drug Transfer
Drugs can enter breast milk through various mechanisms, primarily influenced by their chemical properties and the mother’s physiology. Factors such as the drug’s molecular weight, lipid solubility, and protein binding play critical roles in determining how much of a drug will be excreted into milk. For instance, smaller, more lipid-soluble molecules are more likely to pass into breast milk compared to larger, water-soluble drugs.
Quantities and Safety
Research indicates that while many drugs do transfer into breast milk, the quantities are often minimal. Studies suggest that the amount of drug excreted is typically less than 0.7% of the therapeutic dosage administered to the mother. This low percentage is generally considered too insignificant to pose a clinical risk to the breastfeeding infant. Most commonly used medications are deemed relatively safe, with the doses received via breast milk being much lower than those that would be administered directly to infants.
Clinical Implications
Despite the reassuring data, there remains a tendency for healthcare providers to advise mothers to discontinue breastfeeding when they need medication. This caution can sometimes be excessive, as many medications are safe for use during lactation. The American Academy of Pediatrics emphasizes that only a small number of medications are contraindicated for breastfeeding mothers.
Moreover, the understanding of drug transfer mechanisms has evolved, revealing that carrier-mediated processes are involved in the excretion of certain drugs into milk. This knowledge helps healthcare providers make informed decisions regarding medication management for nursing mothers.
Conclusion
In summary, while drugs can indeed be excreted in breast milk, the amounts are typically very low and unlikely to harm the infant. It is essential for nursing mothers to consult with healthcare professionals about the safety of their medications, as many can be taken without significant risk to their breastfeeding child. The balance between maternal health and infant safety is crucial, and informed decisions can help achieve both.

Which drugs is usually avoided with breastfeeding?

Common medicines that are not recommended when you’re breastfeeding include:

• codeine phosphate.
• decongestants that come as tablets, liquids or powders that you swallow.
• some nasal decongestants that come as nose sprays or drops – check with a GP or pharmacist before using them.
• aspirin for pain relief.

Can anything be passed through breast milk?

Infectious organisms can reach the breast milk either by secretion in the fluid or cellular components of breast milk or by contamination of the milk at the time of or after expression.

What passes through breast milk?

Foods and drinks to avoid while breastfeeding
Caffeine passes into breastmilk, so large amounts of tea, coffee and cola drinks are best avoided. Drinking small amounts of drinks with caffeine (3 or less drinks a day) should not be a problem. Alcohol also passes into breastmilk and can affect your baby.

Can things be transmitted through breast milk?

For some new parents, concerns about breastfeeding revolve less around their babies’ physical condition than their own. Since some infectious diseases can be passed on to the baby through human milk, you will certainly want to discuss your medical history with your doctor and your baby’s pediatrician.

How long does oxycodone stay in breast milk?

Conclusions: Oxycodone is concentrated in human breast milk up to 72-h post-partum. Breastfed infants may receive > 10% of a therapeutic infant dose. However, maternal oxycodone intake up to 72-h post-CS poses only minimal risk to the breast-feeding infant as low volumes of breast milk are ingested during this period.

Which drugs cannot be taken when breastfeeding?

ANSWER: Only a few drugs pose a clinically significant risk to breastfed babies. In general, antineoplastics, drugs of abuse, some anticonvulsants, ergot alkaloids, and radiopharmaceuticals should not be taken, and levels of amiodarone, cyclosporine, and lithium should be monitored.

Which is not excreted in breast milk?

Insulin is not excreted into breast milk and is considered safe for use during breast-feeding.

What drugs are excreted in breast milk?

• analgesics and antipyretics: short courses of paracetamol, acetylsalicylic acid, ibuprofen;
• antibiotics: ampicillin, amoxicillin, cloxacillin and other penicillins, erythromycin.
• bronchodilators (e.g. salbutamol), corticosteroids, antihistamines, antacids.

What substances can pass through breast milk?

A woman’s lifestyle may affect her breast milk, and have an impact on the baby. During breastfeeding, it is important for a woman not to consume alcohol, smoke, or take drugs. These substances are known to pass through the breast milk.

Can drugs be passed through breast milk?

Almost any drug that’s present in the blood will transfer into breast milk to some extent. Most medications do so at low levels and pose no real risk to most infants. There are exceptions, though. Some drugs can be found in high levels in breast milk.
