Runny Nose and Sneezing

Respiratory Symptoms of Cow'S Milk Protein Allergy.

Runny nose is the excess drainage of clear to thick fluid, which can also be yellow-green, from nasal and adjacent tissues in the nose.1  

Sneezing is the sudden, forceful, uncontrolled burst of air through the nose and mouth, caused by irritation to the mucus membranes of the nose or throat.2  

A runny nose is also sometimes called rhinorrhea or rhinitis1 but they are not the same thing. Rhinorrhea has been defined as a thin, mostly clear fluid running from the nose, while rhinitis also constitutes irritation and swelling inside the nose.1 

There are 2 types of rhinitis – allergic and non-allergic. Allergic rhinitis is also called hay fever1, while non-allergic rhinitis is sneezing or a stuffy, drippy nose.1


What Causes
Runny Nose and
Sneezing in

Runny nose, sneezing and rhinitis in infants have many potential causes, it could be related to an infection, such as the common cold or flu, or to allergies, such as hay fever, dust-mite allergy1,2 or CMPA.3 

Could It Be a
Symptom of
Cow’s Milk
Protein Allergy?

Rhinitis symptoms (including runny nose and sneezing) can also be due to Cow’s Milk Protein Allergy (CMPA) and usually manifest quite rapidly following ingestion of milk proteins.3  

However, when considering the diagnosis of CMPA, it’s important to note that the majority of these infants have at least two symptoms affecting at least two different organ systems.4-6

Therefore, it is important to consider the individual child as well as the magnitude of their symptoms.  This can be achieved using an awareness tool such as the Cow’s Milk Related Symptom Score (CoMiSS™) which will help you determine if CMPA might be indicated.7,8

Overview of Symptoms

Up to 30% of affected infants with CMPA have respiratory symptoms15,20

Anaphylaxis icon


Anaphylactic shock is a severe, immediate, allergic reaction, which can affect many organ/systems

Skin icon


Up to 75% of infants with CMPA can have skin-related symptoms21

General Symptoms icon


Inconsolable crying is very common in infants with CMPA associated with sleeping problems and food refusal
