Nonallergic Rhinitis
What is Nonallergic Rhinitis?
Nonallergic rhinitis is an inflammation of the nasal passages and surrounding area that is not caused by an allergic reaction. Symptoms of nonallergic rhinitis can include congestion, sneezing, runny nose, and post-nasal drip. Common causes of nonallergic rhinitis include viral illness, weather changes, certain medications, beverages or foods, and environmental pollutants.
What are the Symptoms of Nonallergic Rhinitis?
Symptoms of nonallergic rhinitis can vary depending on the individual, but can include:
- Stuffy nose
- Constant runny nose
- Itchy nose and/or throat
- Excessive sneezing
- Post-nasal drip and congestion
- Headaches
- Coughing
- Chronic sinus infections
- The inability to smell properly
What Causes Nonallergic Rhinitis?
The most common cause of nonallergic rhinitis is viral infections such as the common cold and the flu. Other possible triggers include weather changes (hot humid air and cold temperatures), certain medications (such as nasal decongestants, ACE inhibitors used to treat high blood pressure, certain hormone treatments, antidepressants, and some medications used to treat diabetes), inhalation of certain pollutants such as smoke and dust, and consuming alcoholic beverages, spicy foods, and certain beverages, such as cold drinks.
Treatment for Nonallergic Rhinitis
Treatment for nonallergic rhinitis depends on the underlying cause. If the cause is a virus, then the symptoms should improve once the virus has cleared up. In cases where the cause is immune system related, medications can help to alleviate the symptoms. These medications may include antihistamines, decongestants, and corticosteroids.
In some cases, surgery may be necessary to relieve chronic sinus infections or blockage. Additionally, environmental allergens should be avoided, if possible, to prevent recurrent episodes of nonallergic rhinitis.
