Can chlorpheniramine maleate be used while breastfeeding? Is the medication found in the breast milk?
First of all, it is best to remember that all antihistamines may reduce breast milk production. It does appear that occasional doses seem to be tolerated well by the mother and child. It isn’t known for sure how much of the medication is present in breast milk, but it is likely the medicine is present in the milk after the mother takes it.
The risk to the infant my be further reduced by taking the medication after the last feeding of the day. Always be sure to check with your healthcare provider before using any medications while breastfeeding.
It does seem that using loratadine while breastfeeding is better tolerated than chorpheniramine. I would encourage you to be an informed mother and have a copy of Medications and Mother’s Milk: A Manual of Lactational Pharmacology handy. This useful reference can give you peace of mind, when determining which medications and supplements are compatible with breastfeeding.
