Allergy cough: What are the indications?

Fact Checked

Some individuals experience an allergy cough if exposed to certain allergens. Cough is how the body naturally prevents allergens and bacteria from entering the body. Once an allergen is breathed in, the body responds by coughing to get rid of it from the throat.

In some instances, an allergic reaction can cause the sinuses to generate mucus that drips down at the back of the throat, resulting to a cough. When it comes to an allergy cough, it can be accompanied by other symptoms due to an allergic reaction.

It is important to note that coughing is the usual indication of an allergy cough, usually due to allergic rhinitis. Once the throat is irritated by an allergen or nasal drainage, the cough reflex reacts by sending out signals to the brain to activate the cough.

Even though coughing is useful in loosening and eliminating the buildup of mucus, it can also irritate the throat, thus increasing the cause of the allergy cough.

Postnasal drip

Postnasal drip is a usual symptom of an allergy cough if the sinuses are inflamed. In an allergic response, the sinus cavity becomes irritated which disrupts with the usual stream of mucus out of the nose.

The mucus slowly drains in the throat. The continuous flow of mucus down the throat triggers irritation and a tickling sensation that triggers a cough. Postnasal drip is managed by dealing with the cause of the drainage. During a reaction, the individual should avoid allergens and use his/her daily antihistamine.


If the cough is brought about by allergic asthma, the cough can be accompanied by wheezing. This condition causes the airways in the lungs to become inflamed, limiting breathing and triggering wheezing.

The wheezing increases from further irritation in the throat. This can be managed by avoidance of the triggers and utilizing medicated inhalers that minimize the inflammation in the airways.
