Allergic cough: symptoms, causes and what to do

Allergic cough is a type of dry and persistent cough that appears whenever a person comes into contact with an allergenic substance, which can be dust (house dust), cat hair, dog hair or pollen from grasses and trees, for example.

This type of cough is more common in spring and autumn, although it can also appear in winter, as environments tend to be more closed at this time of year, generating accumulation of allergenic substances in the air.

Causes of Allergic Cough

Allergic cough is usually related to a respiratory allergy, the main causes being dust (house dust) and plant pollen, for example.

In addition, allergic cough can happen due to the presence of fungi in the environment, animal hair and feathers or substances present in the environment, such as perfumes, swimming pool chlorine or cigarette smoke, for example. Thus, it is normal for people who have allergic cough to suffer from rhinitis or sinusitis, for example.

Main symptoms

Allergic cough is characterized by being dry, persistent and irritating, that is, a cough in which there is no phlegm or any other secretion, which happens several times a day, especially at night, and when it starts, it doesn’t seem to stop.

The person may have a respiratory allergy and not know it. Therefore, if there is a dry and persistent cough, it is important to go to the allergist for an allergy study. Children of allergic parents are more likely to develop a respiratory allergy and are therefore more likely to suffer from persistent dry cough.

How is the treatment done

Treatment for allergic cough should be based on its cause, starting with avoiding contact with the allergenic substance. For immediate relief an antihistamine may be indicated. Drinking more water than usual will help soothe your throat, reducing your cough a bit. The doctor will then indicate specific and effective treatment.

Allergic cough syrup

Homemade syrups are a great option to alleviate symptoms related to allergic cough. Carrot syrup and honey or oregano syrup are good options to combat the symptoms of allergic cough, as these foods have properties that reduce the cough reflex. See how to prepare homemade cough syrups.
