Allergic rhinitis, also called seasonal allergic rhinitis is defined as "rhinitis that occurs at the same time every year. It is characterized by acute conjunctivitis with lacrimation and itching, and regarded as an allergic condition triggered by specific allergens."[1]
Cause / etiology
Allergic rhinitis may be associated with bronchial hyperreactivity.[2]
Diagnosis
Treatment
Clinical practice guidelines by written by authors with conflict of interests address the treatment.[3]
Among alpha adrenergic receptor agonists, pseudoephedrine may be better than phenylephrine in the improvement of nasal congestion.[4]
The most effective treatment is intranasal corticosteroids according to systematic reviews of randomized controlled trials.[5][6]
Combination treatment
Regarding adding histamine H1 antagonists to intranasal corticosteroids:
- Intranasal histamine H1 antagonists may help. Azelastine nasal spray and fluticasone nasal spray in combination may be more effective than either used alone according to a randomized controlled trial that was not registered and had conflict of interest.[7]
- However oral histamine H1 antagonists may not help.[8][9][10][11][12]
