Can you take letrozole when breastfeeding?

Letrozole and Breastfeeding: What You Need to Know
Letrozole, a medication primarily used in the treatment of hormone receptor-positive breast cancer and for fertility issues, raises significant concerns when it comes to breastfeeding. As many mothers navigate the complexities of medication use while nursing, understanding the implications of taking letrozole during this period is crucial.
Current Recommendations
The consensus among health professionals and medical literature is clear: letrozole is not recommended for use while breastfeeding. The manufacturer of letrozole advises that breastfeeding should be discontinued during the course of treatment and for at least three weeks after the last dose. This precaution stems from the lack of comprehensive studies on how letrozole interacts with breast milk and its potential effects on nursing infants.
Potential Risks to Infants
While specific data on letrozole’s transfer into breast milk is limited, experts suggest that the amount could be significant compared to other medications. Letrozole functions by inhibiting estrogen production, which could potentially interfere with hormonal development in infants. Given that hormones play a critical role in growth and development, the risks associated with exposure to letrozole through breast milk are a serious concern.
Alternatives and Considerations
For mothers who are prescribed letrozole, the recommendation is often to explore alternative feeding options during treatment. This may include using formula or expressed breast milk that has been pumped and discarded, a practice commonly referred to as “pumping and dumping.” Some sources suggest that after a period of about ten days post-treatment, it may be safer to resume breastfeeding, but this is contingent on individual circumstances and should be discussed with a healthcare provider.
Conclusion
In summary, if you are breastfeeding and considering or currently taking letrozole, it is essential to consult with your healthcare provider. They can provide personalized advice and help weigh the benefits of treatment against the potential risks to your child. The overarching guidance remains that discontinuing breastfeeding during letrozole therapy is the safest course of action to protect the health and development of your infant.
