| | Allergy & Asthma Disease Management Center: Ask the Expert: Nasal Congestion |
 | | The differential diagnosis of nasal congestion and cough in a 4 month old infant includes a long list of infectious diseases (congenital syphilis, tuberculosis, URI, sinusitis, infectious rhinitis, etc), anatomic abnormalities (choanal atresia, adenoidal hypertrophy), allergic diseases (asthma, rhinitis, food allergy), and genetic disease (cystic fibrosis). |
 | | I would start with an inclusive physical examination directed at determining whether any pulmonary or nasal pathology is evident (check patency of nares, characterize nasal discharge-clear or greenish yellow-green, lung exam, growth parameters). |
 | | On the other hand, if nasal congestion is the predominant symptom, nasal steroids will generally be effective while antihistamines have very little effect on congestion. |
