Which drugs are secreted in breast milk?

Understanding Drug Secretion in Breast Milk
Breastfeeding is a crucial aspect of infant nutrition, but it raises important questions regarding the safety of medications taken by nursing mothers. Many drugs can be secreted into breast milk, and understanding which ones are present and their potential effects on infants is essential for new mothers and healthcare providers alike.
How Drugs Enter Breast Milk
The transfer of drugs into breast milk is influenced by several pharmacokinetic factors, including the drug’s molecular weight, lipid solubility, and protein binding. Generally, smaller, more lipid-soluble drugs are more likely to be excreted into breast milk. The concentration of a drug in breast milk can vary significantly based on these factors, as well as the timing of the dose relative to breastfeeding.
Commonly Found Drugs in Breast Milk
Research indicates that many commonly used medications are relatively safe for breastfeeding mothers and their infants. The amount of drug that a breastfeeding infant receives through milk is typically much lower than the doses that would be administered directly to infants. Some specific drugs that have been identified in breast milk include:
– Caffeine: Found in varying amounts, caffeine can be consumed in moderation by breastfeeding mothers, but excessive intake should be avoided.
– Codeine and Morphine: These opioids can also be present in breast milk, particularly when mothers take combination analgesics that include these substances.
– Acetaminophen and Salicylic Acid: Common pain relievers, these drugs have been detected in breast milk following maternal use.
While many medications are safe, some are contraindicated during breastfeeding. For instance, certain antibiotics like nitrofurantoin should be avoided due to potential risks, especially in infants with specific conditions like G6PD deficiency.
The Importance of Medical Guidance
Despite the presence of some drugs in breast milk, many mothers are often advised to discontinue breastfeeding or avoid necessary medications due to fears of adverse effects on their infants. However, this cautious approach may be unnecessary for many medications, as only a small proportion are truly contraindicated. Healthcare providers play a vital role in weighing the benefits of medication for the mother against the potential risks to the infant, ensuring that both mother and baby receive appropriate care.
Conclusion
In summary, while various drugs can be secreted into breast milk, the majority of commonly used medications are considered safe for breastfeeding mothers. Understanding which drugs are present and their potential effects is crucial for informed decision-making. Mothers should consult healthcare professionals to navigate medication use while breastfeeding, ensuring the health and safety of both themselves and their infants.

Which drugs are excreted through breast milk?

In addition, a study is described confirming the presence of caffeine, codeine, morphine, phenacetin, acetaminophen, and salicylic acid in the breast milk of a lactating mother following oral administration of a combination analgesic containing aspirin, phenacetin, caffeine, and codeine.

What substances are passed through breast milk?

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. This information can help mothers to understand better about the consequences of smoking, using drugs, and drinking alcohol during pregnancy.

How can I reduce my baby’s exposure to drugs in breast milk?

Timing of feeds

1. give the mother’s dose immediately after the infant has been fed with the aim of avoiding feeding at peak milk concentrations; or.
2. withhold breastfeeding until after a suitable washout period of the medicine. This is most appropriate for short courses of a hazardous medicine.

Are most drugs excreted through the lungs and the breastmilk True or false?

In most cases, the amount of excreted drug in the intestine, saliva, sweat, breast milk and lungs is negligible. However, some volatile anesthetics can be exhaled via the lungs. Also, even small drug concentrations in breast milk of lactating women may affect a breastfeeding infant.

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.

How can I breastfeed my boyfriend but not pregnant?

Inducing lactation in people who aren’t pregnant requires medication that mimics hormones your body makes during pregnancy. Suckling from the nipple can initiate lactation, either with a breast pump or by a baby.

• Amphetamines.
• Chemotherapy drugs.
• Chloramphenicol (an antibiotic)
• Radioactive substances used for diagnostic procedures.
• Illicit drugs such as , heroin, and phencyclidine (PCP)
• Medications that may suppress milk production.
