In the UK, nearly 92% of people report using at least one over-the-counter medication annually. These medications, which include common remedies like pain relievers or cold treatments, provide convenient solutions for mild health issues. However, certain drugs are not ideal for breastfeeding mothers, as they can either interfere with the breastfeeding process or pose potential risks to the infant.
Here are 5 Common Medications to Avoid While Breastfeeding:
-
Oral Decongestants
Many people experience two to three colds per year, leading to the widespread use of over-the-counter oral decongestants, such as pseudoephedrine and phenylephrine. These medications can alleviate nasal congestion, but breastfeeding mothers should avoid them.
Studies show that even a single dose of an oral decongestant can reduce milk production by significantly lowering prolactin, the hormone responsible for milk synthesis. Continued use could permanently impair milk supply, which is particularly concerning for new mothers or those with initially low milk production.
Safer alternatives include decongestant nasal sprays containing xylometazoline or oxymetazoline, which work locally and have minimal systemic absorption. Steam inhalation and saline nasal drops are also non-intrusive remedies for relieving congestion.
-
Codeine
Codeine, an opioid painkiller often found in over-the-counter medications like co-codamol, can pass into breast milk and affect the baby. This is particularly risky for newborns or premature infants, as it can cause excessive drowsiness and respiratory issues. In rare cases, the effect has been linked to infant fatalities.
For pain relief, mothers should consider safer options like paracetamol or ibuprofen, which pose less risk to the baby and are generally considered safe when taken at recommended doses.
-
Aspirin
Aspirin (acetylsalicylic acid) is a popular anti-inflammatory medication used to treat pain and reduce fever. However, high doses over an extended period can lead to the medication passing into breast milk. Additionally, aspirin is associated with Reye’s syndrome, a rare but serious illness that affects the brain and liver in children under 16.
Some aspirin-based products may also contain caffeine, which can pass through breast milk and potentially lead to a restless baby. Instead of aspirin, ibuprofen is a safer alternative for pain management, and antacid or alginate medications are preferable for treating upset stomachs.
-
Chlorphenamine
Chlorphenamine is an antihistamine used to relieve allergy symptoms such as hay fever. However, breastfeeding mothers should be cautious when using chlorphenamine, as it can cross into the breast milk and cause drowsiness in the infant. This drowsiness can interfere with feeding and lead to issues like poor weight gain in the baby.
While occasional, low doses might be acceptable, it is advisable to opt for non-drowsy antihistamines such as loratadine or cetirizine. Steroid nasal sprays like beclomethasone and sodium cromoglicate eye drops, which act locally, are also safe alternatives.
-
Combined Oral Contraceptives
Combined oral contraceptives, which contain estrogen, are available over the counter in some pharmacies as part of the NHS contraceptive service. However, mothers who are breastfeeding should avoid these pills. Estrogen can suppress prolactin levels, potentially reducing milk production, especially in the early stages of breastfeeding.
Safer contraceptive options for breastfeeding mothers include progestin-only pills (also known as the “mini-pill”) or non-hormonal methods like the copper intrauterine device (IUD).
It is important for breastfeeding mothers to consult the information on drug packaging and, if uncertain, seek advice from a healthcare professional, such as a pharmacist or GP. In many cases, the impact on milk supply is temporary and reversible, especially with short-term use or lower doses of medication.
Commentary by YourDailyFit columnist Alice Winters:
This article offers a practical guide for breastfeeding mothers concerned about the potential effects of over-the-counter medications on their milk supply and the health of their infants. The focus on widely used drugs such as oral decongestants, codeine, and aspirin is crucial, as these are common culprits in many households, yet their risks during breastfeeding are not always well understood.
Ingredient Impact and Risk Analysis:
The discussion surrounding oral decongestants is particularly relevant. Pseudoephedrine and phenylephrine, often used for nasal congestion, are effective for their intended purpose but can significantly interfere with prolactin production, the hormone central to lactation. While the article accurately points out the systemic impact of these decongestants, a more nuanced exploration of the biochemical pathways could further enrich this analysis. For instance, pseudoephedrine inhibits the release of prolactin via its action on adrenergic receptors, which can cause a substantial decrease in milk volume. This information could be beneficial for more scientifically inclined readers, especially those who are familiar with pharmacological mechanisms.
The mention of codeine is also critical, as the risks to the infant, including fatal respiratory depression, have been well-documented. Codeine, which is metabolized into morphine in the liver, can have unpredictable effects on infants, especially in cases where the mother is a rapid metabolizer. The inclusion of a discussion on genetic variations in the CYP450 enzyme system, which affects codeine metabolism, could provide more depth on why some mothers may be more at risk than others. The safer alternatives—paracetamol and ibuprofen—are appropriately recommended, with both being considered low-risk for breastfeeding mothers. However, it is important to note that ibuprofen’s anti-inflammatory properties may be more beneficial than paracetamol for some types of pain.
The risks of aspirin and its potential link to Reye’s syndrome in children are rightly emphasized, though the article could further elaborate on the mechanisms by which aspirin crosses into breast milk and its long-term effects. There is growing research into the subtle effects of prolonged low-dose aspirin use, particularly in relation to developmental health, that would complement the warnings on Reye’s syndrome.
The coverage of chlorphenamine, an antihistamine, is another key point. While its sedative effects on infants are well-documented, the article could further highlight the risks of prolonged sedative effects, particularly in terms of delayed developmental milestones in the infant. Chlorphenamine’s sedative properties, while less of a concern for adult users, can have long-term implications for a growing child, especially when coupled with disturbed feeding routines.
Lastly, the section on combined oral contraceptives is vital for raising awareness among breastfeeding mothers. The impact of estrogen on prolactin and its potential to reduce milk supply is often underestimated. More information on the different formulations of the “mini-pill,” such as desogestrel and norethindrone, would provide further insight into how these options might suit different breastfeeding women.
Conclusion:
Overall, the article succeeds in providing practical, evidence-based guidance for breastfeeding mothers. However, it could benefit from a deeper exploration of the underlying pharmacodynamics of each drug discussed, as well as more details on the latest research regarding long-term or low-dose use of these medications. Such enhancements would not only improve its value for general readers but also increase its credibility among health-conscious audiences.
