Allergic rhinitis
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 a systematic review of randomized controlled trials.[5]
Combination treatment
It is not clear if histamine H1 antagonists add to the effect of intranasal corticosteroids:
- Azelastine nasal spray and fluticasone nasal spray in combination may be more effective than either used alone according to a randomized controlled trial.[6]
- However, mometasone monotherapy may be as effective as mometasone combined with loratadine.[7]
