Pregnancy Category:NR

Breastfeeding: Dexbrompheniramine: Small, occasional doses of dexbrompheniramine may not cause any adverse effects in breastfed infants. Larger doses or prolonged use may cause effects in the infant or decrease the milk supply, particularly in combination with a sympathomimetic such as pseudoephedrine 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.Pseudoephedrine: A small amount of pseudoephedrine is excreted in breastmilk and is unlikely to harm the nursing infant, occasionally causes irritability. A single dose of pseudoephedrine decreases milk production acutely and repeated use interferes with lactation. Mothers of newborns or who are having difficulties producing sufficient milk should not receive pseudoephedrine. This information is based upon Lactmed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 11 December 2012). Manufacturer advises do not breastfeed while using this drug.
