Since the last update we have not found published data on its excretion in breast milk.

No problems requiring medical attention have been observed in infants of mothers taking chlorpheniramine (Ito 1993, Paton 1985).

Likely inhibition of lactation within the first weeks post delivery because anti-prolactin effect (WHO 2002, Messinis 1985).

Short-term and low dose (2 mg one or twice-day) treatment is compatible with breastfeeding (Lactmed).
Follow-up for sedation and feeding ability of the infant (Butler 2014, WHO 2002).
For long-term treatment an alternative drug should be preferred (Powell 2007).

Compounds in association with expectorants, corticoids and cough relief medicines are available. Avoid drug associations especially while breastfeeding.

Bed-sharing is not recommended for mothers who are taking this medication (UNICEF 2013, Landa 2012, ABM 2008, UNICEF 2006).
