Respiratory allergies cause irritation and swelling in the nose. They are caused by an overreaction of the immune system to allergens, such as pollen, dust mites, or mold. They can cause a runny nose, itchy eyes, sneezing, and coughing.

Allergens cannot always be avoided. Symptoms may be managed with medicines, such as antihistamines and steroids. Some people turn to homeopathic medicine to further ease symptoms.
