Dextromethorphan Breastfeeding Warnings

Benefit should outweigh risk

Excreted into human milk: Unknown
Excreted into animal milk: Data not available

Comments:
-Excretion of this drug into breast milk has not been studied, however, usual doses are unlikely to cause harm to a nursing infant, especially infants older than 2 months.
-As many cough syrups contain alcohol, be sure to check labels and avoid alcohol containing products.

Based on the low molecular weight of dextromethorphan some passage into breast milk probably occurs. However, maternal use of dextromethorphan products that do not contain alcohol are probably safe to use during breast-feeding.
