Chemical structure

Drug Levels and Effects

Summary of Use during Lactation

Small (2 to 4 mg), occasional doses of chlorpheniramine are acceptable during breastfeeding. Larger doses or more prolonged use might cause effects in the infant or decrease the milk supply, particularly in combination with a sympathomimetic such as spseudoephedrine or before lactation is well established. Single bedtime doses after the last feeding of the day may be adequate for many women and will minimize any effects of the drug. The nonsedating antihistamines are preferred alternatives, though.

Effects in Breastfed Infants

In one telephone follow-up study, mothers reported irritability and colicky symptoms 10% of infants exposed to various antihistamines and drowsiness was reported in 1.6% of infants. None of the reactions required medical attention. In this study, no side effects were reported among 5 infants exposed to chlorpheniramine in breastmilk.[1]

Effects on Lactation and Breastmilk

Dexchlorpheniramine in relatively high doses given by injection can decrease basal serum prolactin in nonlactating women and in early postpartum women.[2][3] However, suckling-induced prolactin secretion is not affected by dexchlorpheniramine pretreatment of postpartum mothers.[2] Whether lower oral doses of chlorpheniramine have the same effect on serum prolactin or whether the effects on prolactin have any consequences on breastfeeding success have not been studied.

Alternate Drugs to Consider

Desloratadine, Fexofenadine, Loratadine
