Asthma and allergy coughs are typically caused by swelling or irritation of the airways. Allergies like hay fever can cause a chronic dry cough. If you're sensitive to dust, pet dander, pollen, mold, some food items or other common allergens, then your allergy symptoms may include a cough. Chronic allergies, hyperactive gag reflex, and acid reflux can create a prolonged irritation in your throat and cause an ongoing cough.

A cough caused by allergies can be similar to a cough caused by a cold, but they may differ in subtle ways. A cough caused by allergies is usually dry and may feel like an itch or tickle in your throat. Coughs caused by colds tend to be wet and productive, which means you will cough up mucus.

Antihistamines, nasal sprays, and decongestants are a few of the remedies that can help relieve an allergy cough.

An allergy can also set off asthma symptoms, triggering cough and other breathing problems.With asthma, you are more likely to experience chest tightness, shortness of breath, and wheezing due to the narrowing of the airways of the lungs.
