Treatment includes avoidance of allergens, medical treatment and allergen immunotherapy (allergy vaccines, drops or tablets with allergens). Avoidance of allergens means reduction of allergen load to the respiratory system from the environment, including workplace, which is not easy to accomplish.
Medical treatment is usually necessary to control symptoms, and it includes antihistamines, nasal or in tablets, and nasal glucocorticoids (steroids).
Antihistamines should be second generation, which do not cause sedation, and such treatment shows more efficacy on runny nose, sneezing and nasal itch than on nasal stuffiness.
Nasal steroids are more potent in improving nasal patency than antihistamines, and are at least as potent in the control of all other nasal and ocular symptoms.
Nasal patency may be improved by nasal or oral decongestants, but such treatment should be reduced to as short period as possible. as after few days of use of nasal decongestants rebound congestion may occur and patients remain with a need for nasal decongestants to improve nasal airways even after allergens are not around (like after pollen season).
Viral rhinitis is a part of common cold and usually lasts up to 10 days. Besides previously mentioned nasal symptoms, like obstruction, runny nose and sneezing, other symptoms also often occur, like sore throat, cough and headache. Treatment, analgesics and antipyretics, should improve general symptoms. Nasal symptoms are improved with saline nasal douching. Good hydration, drinking fluids and resting are also recommended.
Some patients respond to antileukotriene drugs which are usually prescribed for asthma.
For non-allergic-non-infectious rhinitis, such patients should avoid exposure to triggers that cause symptoms. If symptoms are often present even without environmental triggers, they may be treated with nasal steroids, if their dominant symptom is obstruction or nasal anticholinergic ipratropium bromide, if they complain of runny nose.
