Newer, less-sedating antihistamines also have no proven effectiveness for vasomotor rhinitis, and their administration delays proper treatment while incurring significant cost and burden to the health care system.3 According to the AHRQ report,6 there has been only one study regarding the use of oral antihistamines, and that study used an antihistamine-decongestant combination product, so the benefit of individual components could not be determined.15The empiric use of the topical decongestant ephedrine on a chronic basis has resulted in tolerance and development of rhinitis medicamentosa.The inclusion of benzalkonium chloride as a preservative has been speculated to contribute to the development of these problems.Preventive and nonpharmacologic approaches should be tried before beginning medication in children.Approved for use in patients six years and older, nasal anticholinergics such as ipratropium (Atrovent) often reduce rhinorrhea without the undesirable side effects of sedation and fatigue sometimes associated with oral antihistamine use.26 However, anticholinergics have no effect on the other symptoms of vasomotor rhinitis.In studies and in practice, allergic rhinitis is excluded or implicated as the cause of symptoms by using conventional skin testing or by evaluation for specific Ig E antibodies to known allergens.7 According to the AHRQ,6 the results of “only one small recent study suggest that total serum Ig E may be as useful as specific allergy skin prick tests, which, in turn, are more useful than radioallergosorbent testing in confirming a diagnosis of allergic rhinitis.”8 The lack of sensitivity and specificity of nasal cytology, total serum Ig E, and peripheral blood eosinophil counts, which have been favored in the past for differentiating among rhinitis syndromes, makes their clinical use problematic.1 The minimum level of testing needed to confirm or exclude a diagnosis of vasomotor rhinitis has not been established in the literature.6Once a working diagnosis of vasomotor rhinitis has been made, the patient can be empowered to avoid known environmental triggers as much as possible.These may include odors (e.g., cigarette smoke, perfumes, bleach, formaldehyde, newspaper or other inks); auto emission fumes; light stimuli; temperature changes; and hot or spicy foods.According to a 2002 evidence report published by the Agency for Healthcare Research and Quality (AHRQ), there is insufficient evidence to reliably differentiate between allergic and nonallergic rhinitis based on signs and symptoms alone.The minimum level of diagnostic testing needed to differentiate between the two types of rhinitis also has not been established. Specific approaches to the management of rhinitis in children, athletes, pregnant women, and older adults are discussed.
If the presenting symptom is solely rhinorrhea, a topical anticholinergic is the logical first step.614 With nasal congestion and obstruction only, topical corticosteroids would be a wise starting point for therapy.6 If the patient presents with the full range of symptoms including rhinorrhea with sneezing, postnasal drip, and congestion, a topical antihistamine may be initiated.6 describes a possible approach.
An algorithm is presented that is based on a targeted history and physical examination and a stepwise approach to management that reflects the AHRQ evidence report and U. A = consistent, good-quality, patient-oriented evidence; B = inconsistent or limited-quality, patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series.

The vasomotor nasal effects of emotion and sexual arousal also may be caused by autonomic stimulation.
In one small study,4 researchers concluded that autonomic system dysfunction is significant in patients with vasomotor rhinitis (No specific test is available to diagnose vaso-motor rhinitis.
