What Medications Cannot Be Given While Breastfeeding?

It’s crucial for nursing mothers to be aware of the potential risks associated with taking medications while breastfeeding. While many drugs are considered safe for breastfeeding infants, there are certain medications that should be avoided to protect the health and well-being of the baby.

Antineoplastics: A Potential Risk

Antineoplastic drugs, which are used in the treatment of cancer, are among the medications that should not be given while breastfeeding. These drugs can pose a significant risk to breastfed babies due to their potential side effects and adverse reactions.

Drugs of Abuse: Avoid at All Costs

Drugs of abuse, such as recreational drugs and substances like heroin and cocaine, should never be taken by breastfeeding mothers. These substances can be harmful to the baby and can have long-lasting effects on their health.

Anticonvulsants: Exercise Caution

Some anticonvulsant medications may pose a risk to breastfeeding infants. It’s important for nursing mothers who are taking anticonvulsants to consult with their healthcare provider to determine the best course of action to ensure the safety of their baby.

Ergot Alkaloids: Best to Avoid

Ergot alkaloids, which are used in the treatment of migraines and postpartum hemorrhage, should not be taken while breastfeeding. These medications can have serious consequences for the baby’s health and development.

Radiopharmaceuticals: Not Recommended

Radiopharmaceuticals are another category of drugs that should be avoided while breastfeeding. These medications can have radioactive properties that can be harmful to the baby, making it essential to seek alternative treatment options.

While some medications may not be explicitly contraindicated for breastfeeding, it’s essential to monitor the levels of certain drugs in the mother’s system. Medications like amiodarone, cyclosporine, and lithium fall into this category, requiring close monitoring to prevent any potential harm to the baby.
