Common adverse effects that occur with the use of intranasal decongestants are sneezing and nasal dryness. Combination therapy with azelastine hydrochloride nasal spray and fluticasone propionate nasal spray in the treatment of patients with seasonal allergic rhinitis. Sublingual immunotherapy with once-daily grass allergen tablets: a randomized controlled trial in seasonal allergic rhinoconjunctivitis. Specific immunotherapy for respiratory allergy: state of the art according to current meta-analyses. Effect of omalizumab on symptoms of seasonal allergic rhinitis: a randomized controlled trial.
Although there is no evidence that one intranasal corticosteroid is superior to another, many of the available products have different age indications from the U. One RCT found the rate of skeletal growth unaffected in children using mometasone for one year.17 Similarly, a well-designed prospective study did not show any difference in growth in children using nasal corticosteroids for at least three years.18 However, one randomized trial of 90 children (six to nine years of age) who were treated with beclomethasone (Beconase) or placebo for one year showed suppressed growth rates in the group taking beclomethasone compared with the placebo group.19 Although nasal fluticasone has been shown to reduce endogenous cortisol excretion in one study, its impact on growth is unknown.20 Despite the data, all intranasal corticosteroids carry a warning that long-term use may restrict growth in children.
Although cetirizine is a second-generation antihistamine and a more potent histamine antagonist, it does not have the benefit of decreased sedation.
As a group, the second-generation oral antihistamines are thought to stabilize and control some of the nasal and ocular symptoms, but have little effect on nasal congestion.21In general, first- and second-generation antihistamines have been shown to be effective at relieving the histamine-mediated symptoms associated with allergic rhinitis (e.g., sneezing, pruritus, rhinorrhea, ocular symptoms), but are less effective than intranasal corticosteroids at treating nasal congestion.

Advantages include that it does not cross the blood-brain barrier and is not systemically absorbed.1 Adverse effects include dryness of the nasal mucosa, epistaxis, and headache.
Compliance is also an issue because it needs to be administered two or three times daily.1Although the leukotriene LTD receptor antagonist montelukast (Singulair) is FDA approved for the treatment of allergic rhinitis, a systematic review of 20 trials involving adults treated with montelukast for allergic rhinitis showed only minimal improvement (which was not clinically relevant) in the symptom of nasal congestion.32 Another RCT involving 58 adults comparing montelukast with pseudoephedrine for two weeks showed no difference between the two therapies.33 In addition, two large, independent meta-analyses concluded that although montelukast is better than placebo, it is not as effective as intranasal corticosteroids or antihistamines and should only be considered as second- or third-line therapy.3234Although many studies have looked at the combination of an intranasal corticosteroid with an antihistamine or leukotriene receptor antagonist, most have concluded that combination therapy is no more effective than monotherapy with intranasal corticosteroids.1137 However, one study looking at the combination of fluticasone and azelastine found this treatment combination to be superior to either treatment alone in patients with moderate to severe allergic rhinitis.38 Therefore, although patients should not have therapy initiated with more than one agent, combination therapy is an option for patients with severe or persistent symptoms. Ten days' use of oxymetazoline nasal spray with or without benzalkonium chloride in patients with vasomotor rhinitis.
Although the precise mechanism by which acupuncture works is unclear, proponents suggest that it releases neurochemicals such as beta-endorphins, enkephalins, and serotonin, which in turn mediate the inflammatory pathways involved in allergic rhinitis. Absence of growth retardation in children with perennial allergic rhinitis after one year of treatment with mometasone furoate aqueous nasal spray.
Based on RCTs looking at acupuncture as a treatment for allergic rhinitis in adults and children, there is insufficient evidence to support or refute its use.4649Based on the limited data to date, probiotics cannot be endorsed as a useful alternative therapy for allergic rhinitis. Kaszuba SM, Baroody FM, de Tineo M, Haney L, Blair C, Naclerio RM. Although safe for general use, intranasal cromolyn (Nasalcrom) is not considered first-line therapy for allergic rhinitis because of its decreased effectiveness at relieving the symptoms of allergic rhinitis and its inconvenient dosing schedule.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.Symptoms include rhinorrhea, nasal congestion, obstruction, and pruritus.1 Optimal treatment includes allergen avoidance, targeted symptom control, immunotherapy, and asthma evaluation, when appropriate.2 In 2001, Allergic Rhinitis and Its Impact on Asthma guidelines were published in cooperation with the World Health Organization, suggesting that the treatment of allergic rhinitis make use of a combination of patient education, allergen avoidance, pharmacotherapy, and immunotherapy.3 In contrast with previous guidelines, these recommendations are based on symptom severity and age, rather than the type or frequency of seasonal, perennial, or occupational exposures.The adverse effects and higher cost of intranasal antihistamines, as well as their decreased effectiveness compared with intranasal corticosteroids, limit their use as first- or second-line therapy for allergic rhinitis.Immunotherapy should be considered for patients with moderate or severe persistent allergic rhinitis that is not responsive to usual treatments.8 Targeted immunotherapy is the only treatment that changes the natural course of allergic rhinitis, preventing exacerbation.39 It consists of a small amount of allergen extract given sublingually or subcutaneously over the course of a few years, with maintenance periods typically lasting between three to five years.
